- 0:00I guess it's just a hot show
- 0:02It's on
- 0:03No
- 0:03[ fulfill for the later part of the Sale ]
- 0:09me in profit ] Well, good evening.
- 0:37It's Wednesday night, 8pm Central Time,
- 0:39and that means it's
- 0:40time for another XJtalk.com
- 0:42show.
- 0:43Full name being Jeep Cherokee XJtalk.com.
- 0:47I kind of want to make it clear that
- 0:49we're here to talk about Jeep Cherokees.
- 0:53Just the Cherokee and better known as XJ.
- 0:57That's why the website name is
- 1:00XJtalk as we talk about them.
- 1:03Tonight we're going to be talking about a
- 1:05couple of, well I
- 1:06think, important things.
- 1:08Gas mileage on your XJ and the overall
- 1:14core design of the
- 1:15cooling system, which I believe
- 1:16is going to be a repeat a
- 1:18bit from my previous show.
- 1:19But summertime is upon us.
- 1:22So I think maybe some of the issues that
- 1:26I have found in gothu
- 1:28on my personal Jeep XJ
- 1:32might be of benefit to you.
- 1:34So we'll get right to that after we
- 1:37finish up playing this music.
- 2:39This segment sponsored by
- 2:414wheelingplus.com. Do you want a Jeep? Do
- 2:44you need help getting
- 2:45it up? Check out 4wheelingplus.com for
- 2:47great deals on Jeep lift
- 2:49kits. That's the number
- 2:504 Wheeling Plus PLUS.com.
- 2:55And I want to remind you guys that we
- 2:57love getting calls in on
- 2:59our voicemail, our feedback
- 3:00line. So, you know, give us a call, leave
- 3:03your comment, leave a
- 3:05message, we'll probably
- 3:06play it on the air. Here's that number.
- 3:08Do you have questions or comments that
- 3:09you would like played
- 3:10on the air? We've set up
- 3:11voicemail just for that purpose. All you
- 3:14have to do is call
- 3:15530-675-4102. Just leave your
- 3:21name, your location, and your question or
- 3:24comment. Chances are
- 3:25good it'll get played
- 3:26on the air. That number again is
- 3:28530-675-4102. We look
- 3:34forward to hearing from you today.
- 3:36Also too, if you've got something to talk
- 3:38about, it doesn't
- 3:39necessarily have to be about
- 3:41Jeeps. Jeep related is good. You don't
- 3:44want a Jeep talk show.
- 3:46But we're interested in
- 3:48other things. It may be something that
- 3:51indirectly pertains to
- 3:53Jeeps. It may be a bitter oil
- 3:56product that you've had direct experience
- 3:59with. And maybe it's not even with a Jeep
- 4:03Cherokee. The TJ Wranglers have a very
- 4:09common heritage with the
- 4:11XJs. At least the ones that
- 4:13were made during the same time period and
- 4:16have the 410 liter
- 4:17engine. So, you may have
- 4:20some experiences with engines or
- 4:22drivetrains or the other
- 4:23parts of the drivetrain that
- 4:25might benefit all of us. So, you know,
- 4:27feel free to get in
- 4:29contact with me via the XJTalk
- 4:31website and be a guest. So, as I said in
- 4:36the opening, we're
- 4:37going to be talking about
- 4:38some of the issues that I've gone through
- 4:42with my XJ. And maybe
- 4:45in the hopes of helping
- 4:47you out a bit, I have recently updated
- 4:53the amount of mile per
- 4:55gallon measurements that
- 4:59I've been taking since I believe it was
- 5:01July of 2009. 2009, 10,
- 5:0511, it might be 2008, 2008,
- 5:092009, because I'm coming right up on
- 5:11three years worth of MPG
- 5:14data. And I started recording
- 5:17that data primarily because gasoline
- 5:21prices were spiking
- 5:22pretty bad. And I had just put
- 5:26the lift kit, the 4.5 inch Rough Country
- 5:29lift kit on my Jeep. And I
- 5:31had put the larger tires,
- 5:3532 by 11.5 inches by 15 and the alloy
- 5:41wheels, the 10 by 15 alloy
- 5:43wheels. And I was noticing
- 5:46what seemed to be a gas mileage problem.
- 5:51I had not noticed, and
- 5:53of course I understood
- 5:54that perhaps it wasn't so much that I was
- 5:57noticing the problem
- 5:59as I was noticing how
- 6:00much gas was costing. Because if
- 6:02something is cheap enough,
- 6:05it's below your radar and
- 6:06you really don't pay that much attention
- 6:08to it. Well, I think the
- 6:09combination of the price
- 6:10rising and the gas mileage going down
- 6:14were two critical things
- 6:16that made me care, frankly.
- 6:19So I started measuring that information.
- 6:23And when you lift a vehicle, you
- 6:28understand pretty much
- 6:30going in, especially if you ever have
- 6:31done it in the past, you understand going
- 6:33in, you're not going
- 6:34to get as good a gas mileage simply
- 6:36because you're changing the aerodynamics
- 6:39of the vehicle. And I
- 6:40think more importantly, you're putting
- 6:42more surface area between your vehicle
- 6:46and the road in the form
- 6:48of a larger tire. And let me just answer
- 6:53this question before it
- 6:54comes up. Yes, the speedometer
- 6:56was corrected. If you don't know what I'm
- 6:59talking about, when you change the
- 7:02diameter size of the
- 7:03tire from stock to a larger tire or
- 7:08wheels-hire combination, that
- 7:10basically means that the tire
- 7:12is going to roll further to get back to
- 7:15the same point on the tire. So your
- 7:19speedometer will show
- 7:20slower than what you're actually going.
- 7:23So you actually have to
- 7:24correct that. Now some vehicles,
- 7:26I think you can correct it through the
- 7:28computer, the onboard
- 7:29computer, the ECM. And some have a
- 7:34mechanical means. And there may be those,
- 7:37and the XJ may be included
- 7:40in this, that you can correct
- 7:42either through the ECM or by changing a
- 7:44gear. And the only way I
- 7:46know how to do it is by changing
- 7:47the gear. And I just went on the
- 7:50internet, you guys have heard of the
- 7:52internet I'm sure, and looked
- 7:54up the size tire that I have, the gear
- 7:57ratio that I have in the
- 7:59front and rear differentials, and
- 8:02picked the number of tooth gear that I
- 8:06needed to get it back to the stock
- 8:08setting. So I spent about
- 8:1125 bucks, I think, and I got the 32 or 35
- 8:15or whatever tooth gear it
- 8:16was. And it literally takes
- 8:19about seven minutes to take the one bolt
- 8:22holding the other one in the
- 8:23bracket off and put the new
- 8:28gear in and put it back into the transfer
- 8:31case and put the bolt back
- 8:33in and go on down the road.
- 8:35I really wanted that because the first
- 8:38vehicle that I lifted was a 1983
- 8:42Chevrolet pickup. And
- 8:44there may have been something just as
- 8:46easy to correct that
- 8:47speedometer. If so, I wasn't aware of
- 8:49it. And I drove that truck for quite a
- 8:53while with the speedometer
- 8:55being off. And it's a bit of a
- 8:58scary feeling whenever you're driving
- 9:00around. And especially if
- 9:02there's any police, you know,
- 9:03you're concerned about getting a speeding
- 9:05ticket, especially since I
- 9:07was in my what mid to late
- 9:0920s when I did that. So eventually,
- 9:13looking in a magazine, I found where
- 9:15there was a company that
- 9:16would basically add this little piece of,
- 9:22it was a gear for all
- 9:23intensive purposes, reduction gear
- 9:24set. And that was back in the days of the
- 9:27mechanical
- 9:28speedometer. So you actually had a
- 9:29cable that would come up from the
- 9:31transmission or transfer case
- 9:33all the way to the back of the
- 9:34speedometer in your dash. And that cable
- 9:38would turn and the
- 9:38speedometer needle would turn and
- 9:40measure your speed. So basically, I got
- 9:43this little reduction gear
- 9:44thing or I would assume it was
- 9:47reduction, maybe not, maybe it was an
- 9:48increase. But it basically
- 9:51through the use of a couple of
- 9:53gears, it corrected it and you actually
- 9:57would have to go out and
- 9:58measure time over a fixed
- 10:04distance. And the further the distance,
- 10:07the further the measured distance, the
- 10:10more accurate it was.
- 10:11So anyway, it's a lot easier. It was a
- 10:13lot easier to do on the Jeep and it's
- 10:14just a gear. And the
- 10:16gear is available on many companies
- 10:18online carry those gears. And
- 10:20actually, I got mine from the
- 10:22dealership, local Jeep dealership. And it
- 10:26was about the same price
- 10:28online or just going down to the
- 10:30dealership. So I just did that. So
- 10:33anyway, I did correct the speedometer. So
- 10:36one of the things that
- 10:37I found out, I was on naxja.org website
- 10:43asking questions and trying
- 10:46to gather help from some of
- 10:47the members and visitors there. Tell them
- 10:50that, hey, my gas mileage
- 10:52sucks. And they're basically
- 10:53saying welcome to the club. And I said,
- 10:55yeah, I understand. But
- 10:57interestingly, there was several
- 10:59other people, and of course, it's the
- 11:00internet. Nobody ever lies.
- 11:03But there was several other
- 11:05people that were saying that, hey, I've
- 11:07got 32 inch tires or I've got 33 inch
- 11:10tires and blah, blah,
- 11:11blah, and this bumper and this spare tire
- 11:14and et cetera, et cetera. And I get 600
- 11:15miles of the gallon.
- 11:16And there was enough of them that were
- 11:19saying, and of course, I'm being
- 11:20facetious, they were seeing
- 11:2216 to 18 miles per gallon with this heavy
- 11:30equipment added to their
- 11:32vehicles with speedometers
- 11:34corrected. So highway mileage, of course.
- 11:37And I thought to myself,
- 11:38well, the vehicle is supposed
- 11:41to be rated for 20 miles per gallon
- 11:43highway. And I think we all know that
- 11:46those estimates are never
- 11:47met. I guess in some rare tailwind, jet
- 11:52stream, tornadic activity
- 11:55near your Jeep during the
- 11:58measuring of gas mileage, you might get
- 12:00that. But who knows? But
- 12:02there are people that do get
- 12:04over 20 miles per gallon. Generally
- 12:06speaking, they have standard
- 12:08transmissions. And of course,
- 12:10the nice thing about the standard
- 12:11transmission is you control
- 12:13how much RPM, how much power that
- 12:17you put to the transmission. And more
- 12:19importantly, I believe, how much slippage
- 12:21occurs because there's
- 12:22a lot of slipping going on inside an
- 12:25automatic transmission. And I
- 12:26think they do that partially
- 12:28to make the ride easier, to make it feel
- 12:31smoother because we
- 12:32all know that the Jeep
- 12:34Cherokees are luxury vehicles. But
- 12:36anyway, you do have more
- 12:36control over how much slippage goes
- 12:39between the engine and getting the power
- 12:44to the rear wheels. So I
- 12:45started measuring the MPG
- 12:49for my Jeep. And I was getting around 10
- 12:51miles to the gallon. And
- 12:53I thought that was really,
- 12:54really bad. There was a lot of different
- 12:58things thrown out there
- 12:59from NAXJ members about
- 13:03O2 sensors being bad. You need to change
- 13:07the differential gears
- 13:09because it's taking more power
- 13:12to get the Jeep going. What was another
- 13:15thing that I remember? And
- 13:18over those last three years,
- 13:20I've tried a number of things. I've
- 13:23replaced the fuel
- 13:25injectors from the stock one-hold
- 13:29injector to a Ford Mustang, I think it
- 13:33was a 2009 Ford Mustang
- 13:38injector with, gosh, there was
- 13:41like six or seven holes in that injector.
- 13:44So the idea there giving
- 13:46you a better spray pattern
- 13:49to mix the air and the fuel. And if you
- 13:51get a better pattern, a
- 13:53more diffused pattern,
- 13:54you should get a better burn. And I
- 13:57thought, hey, maybe the injectors are
- 13:58giving me a problem.
- 14:00Anyway, I can get a little ahead of
- 14:01myself. The first thing that
- 14:02I tried were the O2 sensors.
- 14:05And I replaced the two O2 sensors with
- 14:09Bosch, saying that
- 14:11correctly or not, Bosch O2 sensors.
- 14:14And they were about $70 a piece. On the
- 14:171998 Jeep Cherokee like I have, it is,
- 14:22there's only two O2 sensors. One is up
- 14:25close to the exhaust
- 14:29manifold, and one is further away
- 14:32closer to the catalytic converter. And my
- 14:35understanding is that
- 14:36the one closest to the
- 14:37exhaust manifold is the one that is
- 14:40basically telling the
- 14:41computer or giving the computer
- 14:44the information it needs to adjust the
- 14:46air-fuel mixture. And of course, that's
- 14:48critically important
- 14:49in the running of your Jeep, but the
- 14:52efficiency of running of the Jeep,
- 14:55running of the engine.
- 14:56And then the downstream, the one closest
- 15:01to the exhaust sensor
- 15:02would be upstream. The one
- 15:03closer to the catalytic converter would
- 15:05be the downstream O2 sensor. And my
- 15:08understanding is that
- 15:09the downstream O2 sensor measures how
- 15:12well the mixture is being burned.
- 15:16Basically, I think how
- 15:17the catalytic converter is taking care of
- 15:19it. I believe that's
- 15:20right. I believe that's on the
- 15:22back end of the catalytic converter. In
- 15:24other words, it's
- 15:25measuring the mixture after the
- 15:28catalytic converter has done its job
- 15:32trying to scrub up the
- 15:33hydrocarbons out of there.
- 15:35At any rate, the front one I was more
- 15:38concerned with and made no difference.
- 15:42Nothing that I could
- 15:44tell. And I am able to tell, I have heard
- 15:48this before and I've seen
- 15:50this directly. You have to
- 15:51collect a lot of data to be able to see
- 15:55what's going on for your miles per
- 15:59gallon, what your gas
- 16:00mileage is. Because it can vary pretty
- 16:03widely over time. And I'm
- 16:06sorry, not over time, over a short
- 16:08time. And I cannot relate that in three
- 16:12years of data. I cannot
- 16:15relate that to the way I was
- 16:17driving. I don't know why. It goes, I've
- 16:21seen it as low as 11.5, I
- 16:25guess I've seen it down as close to
- 16:2710, almost 11 miles per gallon. And I've
- 16:30seen it as high as, gosh, what was it,
- 16:3413.6, 13.7 miles per
- 16:36gallon. And I mean, we're talking from
- 16:38week to week. And actually, you get a
- 16:42nice sawtooth pattern on
- 16:44the graph. It goes up, it goes down. It
- 16:46goes up, it goes down. And
- 16:48you might get a period in there
- 16:49where two or three weeks will be fairly
- 16:55the same, I mean, within a half, less
- 17:01than a mile per gallon.
- 17:02But it varies widely. And it's really
- 17:06strange. I don't understand that,
- 17:08especially after the ECM has
- 17:12learned your driving habits. The other
- 17:14thing I didn't understand
- 17:15very much was, I can drive like
- 17:18the hypermilers drive. And of course, I'm
- 17:20exaggerating. The
- 17:21hypermiler is basically like,
- 17:23they're usually people driving Hondas.
- 17:26And they plan their courses
- 17:29from wherever they go on work,
- 17:30wherever, where they don't have to stop
- 17:33as much, where they
- 17:34don't have to go very fast,
- 17:36and they can accelerate gradually over a
- 17:39long distance. So they
- 17:41have to plan the most optimum
- 17:43route. They have to plan a route where
- 17:46they, at least here in Texas,
- 17:47don't get shot for driving so
- 17:49slow, or accelerating so slow. But even
- 17:55trying to drive very carefully and slow
- 17:58to accelerate and so
- 17:59forth, I was not seeing a change in gas
- 18:04mileage. Now, it may have
- 18:06shown up if I had done that over
- 18:08a long period of time, but I probably
- 18:10would have killed myself. I probably
- 18:12would have just gone
- 18:12insane and killed myself trying to drive
- 18:15that carefully over a
- 18:17long period of time. I mean,
- 18:18that's one of the fun things about
- 18:19driving the Jeep anyway is, you know,
- 18:22taking off and going.
- 18:24Driving altogether, I guess, is just fun
- 18:26to accelerate. Take the
- 18:28corners sharp, etc., even
- 18:30in a Jeep. So anyway, it basically, you
- 18:35know, I know that it takes
- 18:36more gas to move the Jeep
- 18:40faster. But it just seems like idle or 70
- 18:44miles an hour, it's using
- 18:46about the same amount of gas.
- 18:47So it's your choice. You can, you know,
- 18:49you're going to be going
- 18:50slow, or you can be going fast,
- 18:52or faster. At any rate, the next thing I
- 18:56tried that I recall is
- 18:58replacing the differential gears.
- 19:01The stock differential gears are 3.55.
- 19:06And again, going through
- 19:09NAXJA.org, the members and guests
- 19:13there were suggesting, I mean, and doing
- 19:16my own research, they were
- 19:18suggesting 410 or 450, or
- 19:21sorry, 4.10 or 4.56 gears for the
- 19:26differentials. So basically what that
- 19:29means is that it's going to
- 19:32allow the engine to turn the front and
- 19:36rear axles faster. They
- 19:40will turn more revolutions
- 19:42than what the differential gears that
- 19:45were there, what they would turn the
- 19:48wheels. So you have various
- 19:50ways that you can adjust how much the
- 19:54wheels turn. Certainly if
- 19:55you increase the tire size,
- 19:57that means the tire is not going to turn
- 19:59as many revolutions over a
- 20:02distance. So by changing out the
- 20:04differential gears to a higher numeric
- 20:09gear, or a lower gear
- 20:10ratio, now you're going to be,
- 20:14the tire is actually going, the tire is
- 20:16still going to go over
- 20:17the same distance, but the
- 20:20engine is going to turn more times for
- 20:23that same amount of wheel rotation.
- 20:27Basically what it does
- 20:28is it means that it's going to be easier
- 20:32for the engine to get the mass of the
- 20:35Jeep moving forward,
- 20:37or even reverse. It's going to be easier
- 20:39for the engine to get it
- 20:40going because there's going to
- 20:41be less resistance. Let's see, is
- 20:45resistance, would that be correct? I
- 20:47guess to a degree that's
- 20:49true because it would be like using a
- 20:53lever and you can use a
- 20:54short lever to move something and
- 20:56you have to use more force to get that
- 20:59moving, or you can use a
- 21:01much longer lever and then it
- 21:03doesn't require as much force. So I
- 21:05believe that's a good
- 21:05analogy. It may not be, but anyway,
- 21:08that's what you got. So replace the, I
- 21:11went with, 410 was what I was
- 21:12considering and there was so
- 21:15many people that said, you know, it's a
- 21:18lot of effort, it's a lot
- 21:19of expense to change out the
- 21:22gears. And actually if you have to ask, I
- 21:26was told this, if you have
- 21:27to ask, should I change the
- 21:29differential gears myself, you shouldn't.
- 21:32You shouldn't change
- 21:33them yourself. So I actually
- 21:35had a mechanic change up my differentials
- 21:37and I had to make a big
- 21:39decision since it was going
- 21:40to be rather expensive, not only for the
- 21:44pinion and the ring of
- 21:46the gear and the associated
- 21:48rebuild kits, but also to the charge, the
- 21:52mechanic was going to charge me. So
- 21:56several people said you
- 21:58one gear set higher or lower, depending
- 22:03on if you're looking at
- 22:04the gear number or the ratio,
- 22:10you should get one more than what you
- 22:11want to go because it will, you'll be
- 22:13happier in the long run.
- 22:15So I went back and forth, back and forth,
- 22:18thinking about it and I just
- 22:19went ahead and decided that
- 22:20we'd go with the 456 gears. And I want to
- 22:22tell you, it's great. And
- 22:24also too, I had always planned
- 22:27a larger diameter tire and I knew that as
- 22:32the tire size goes up, you need
- 22:35numerically higher gears to get the same
- 22:39results. So I think maybe I was toying
- 22:41around with the idea
- 22:42of going with some 35 inch tires at that
- 22:45time and 35 inch tires
- 22:47with the 456 gears would be
- 22:51really close to stock gearing. It would
- 22:54be very close as to how
- 22:57the engine, how many RPMs the
- 22:59engine would turn and how much force it
- 23:01would have to give to put out
- 23:03to push the Jeep along. Now,
- 23:05of course, that varies because of the
- 23:07weight of the tires and other
- 23:08things I've added to the Jeep,
- 23:10items that have changed the airflow and
- 23:13also to added additional
- 23:15weight. So I'm sorry, I was just
- 23:17looking here at the chat room and Weldman
- 23:21says, "Tony, what's your
- 23:22RPM at 60 miles per hour?"
- 23:24I don't have it in front of me, but I
- 23:26believe it would be 2500 RPM.
- 23:30I know for a fact that at 80
- 23:33miles an hour, it's 3000 and I believe at
- 23:3670, it is 2800. So yeah,
- 23:42it's pretty high. And just like
- 23:46me on that NAXJ website, the 4.0 can turn
- 23:523000 RPM all day long and
- 23:54it surely can. It has no
- 23:56problem doing that whatsoever. Although I
- 23:58did get heat creep,
- 24:00which was the cooling system
- 24:02gradually heating up and I believe it's
- 24:06because of that additional
- 24:07RPM that the engine is turning.
- 24:10And I'm sure it has to do with airflow
- 24:12and additional weight
- 24:13and so on and so forth
- 24:14and aerodynamics. So anyway, I changed
- 24:17out the 355 gears with 456 gears and
- 24:22continued to measure
- 24:23my fuel consumption versus mileage gained
- 24:30over that fuel usage from
- 24:33week to week. And I say week
- 24:34to week, it's whenever I filled up and
- 24:36generally speaking, I can
- 24:38go a week to whatever job I'm
- 24:41on a tank of gas. And I have the 20
- 24:43gallon tank on the Jeep Cherokee and that
- 24:48effectively is about
- 24:50I think 18.6 gallons is the most I've
- 24:54ever been able to get in a tank. And
- 24:56that's with the power
- 25:00dropping off. In other words, the
- 25:01injectors weren't putting
- 25:04out as much fuel as what they
- 25:06because the tank was almost empty. So I
- 25:10read something about that. I think it's,
- 25:12you have to measure up the tube and it
- 25:14doesn't pick up all the
- 25:15fuel that's in there and so on
- 25:16and so forth. I don't know. They may even
- 25:18have it set that way
- 25:19because they don't want the fuel
- 25:21pump to the fuel pumps in the tank. So I
- 25:24think they do that. They
- 25:25may do that because they don't
- 25:26want the fuel pump to not be in some fuel
- 25:30because they actually use
- 25:31the fuel to cool the fuel pump.
- 25:34And I have, I think I also read someplace
- 25:36you're not supposed
- 25:37to run a tank more than
- 25:40three quarters empty that you needed to
- 25:43have at least a quarter tank
- 25:44of fuel in there. Otherwise,
- 25:45you could overheat the fuel pump. But
- 25:48I've been doing it for
- 25:50the longest time. I mean,
- 25:51I've had this Jeep since 98 and it's
- 25:55still going. Of course,
- 25:57the fuel pump could also be
- 25:58the culprit in a mile per gallon issue.
- 26:03But anyway, I went with the 456 gears,
- 26:05continued to measure the gas mileage, and
- 26:08I noticed a significant
- 26:09jump almost immediately.
- 26:11And it went looking at the graph over
- 26:16just that very short period
- 26:18of time from around July to the
- 26:22end of July. My miles per gallon
- 26:24increased by around two
- 26:26miles to two and a half miles per
- 26:28gallon. Now, that may not seem like that
- 26:31big a deal, but if you're
- 26:33getting around 10 and now
- 26:34you're getting up close to 13 miles per
- 26:38gallon, that makes you
- 26:40feel good that the $1,500 that
- 26:43you spent to have this done by the gears
- 26:47and have them installed. And not to
- 26:50mention the time that
- 26:51I spent there at the mechanics place
- 26:53watching and helping, it
- 26:55makes you feel good that you got
- 26:56a little bang for your buck. Now, I
- 26:59haven't gone through the how much fuel
- 27:00could I have bought and
- 27:02how much fuel did I save? And I probably
- 27:05don't want to know. And
- 27:09that's really it. I mean,
- 27:11that's it. That's the only thing that I
- 27:12have seen a change in three
- 27:15years of collecting mile per
- 27:16gallon data that made any significant
- 27:20improvement. Now, what I will add is over
- 27:23that same time period,
- 27:25I've added a bumper that a front front
- 27:28winch bumper that
- 27:29probably weighs 90 to 100 pounds.
- 27:33I've added a super winch, a 9,000 pound
- 27:37pulling rated pulling super
- 27:39winch that I know is 70 or 80
- 27:43pounds on top of that I've added. And I
- 27:47think I just throw this in
- 27:49because at least from the
- 27:51wind resistance, I've added four KC
- 27:55daylighter, six inch daylighter off-road
- 28:01lights to that bumper,
- 28:02which weighs a little bit. A couple of
- 28:05D-rings on that bumper, so I
- 28:08got all that weight. And even
- 28:10prior to that custom front bumper that I
- 28:12have on there, I added a custom rear
- 28:16bumper and it probably
- 28:18weighs, it probably weighs more than what
- 28:22the front bumper does. Well, it probably
- 28:27weighs about the same actually because
- 28:29the bumper itself probably weighs 90 or
- 28:31so pounds. There's an
- 28:32additional tire carrier added to that
- 28:36bumper so that I can put a
- 28:37spare tire. And then also
- 28:40there's the spare tire, which is probably
- 28:4440, 50 pounds, maybe more.
- 28:48So all's hold, we're probably
- 28:50talking about 300 pounds of weight added
- 28:53to the Jeep just in
- 28:54bumpers, winch, and spare tire. And
- 28:59I guess really that's about it for the
- 29:01weight adding because it
- 29:03already had skid plates
- 29:04at various places. I did take the front
- 29:06skid plate off, which
- 29:08I'm going to put back on
- 29:10just to see if I can help the heat creep
- 29:12problem, but to promote
- 29:15airflow through the radiator
- 29:16instead of maybe under the Jeep. But
- 29:19anyway, so that's one thing
- 29:21that I found very interesting.
- 29:22You hear a lot on the forums that adding
- 29:28this additional weight
- 29:30to your Jeep is going to
- 29:33really hurt your gas mileage. At least in
- 29:36my case, not true.
- 29:38Absolutely not true. Now it is always
- 29:42possible that the various things that
- 29:44I've been trying to
- 29:45improve my gas mileage have been,
- 29:48are not visible over a very short period
- 29:51of time in the measurement
- 29:53of my gas mileage. And those
- 29:56improvements actually are offsetting the
- 29:59negative things that I've
- 30:00done to the Jeep as far as gas
- 30:02mileage goes. And those negative things
- 30:04would be the addition of all
- 30:06that weight and the change in
- 30:08airflow around the general brick shape of
- 30:12the Jeep. So I don't know.
- 30:19All I can tell you is that
- 30:21I have not seen a difference in gas
- 30:23mileage. I am still getting the, most of
- 30:27the time it's around
- 30:2912.7, 12.8 to 13.2, 13.3. With
- 30:34opportunities to go to 13.6 and I do a
- 30:38little dance and a little
- 30:41smiley face as I'm accelerating wildly
- 30:44going to work. I usually
- 30:46fill up, get gas on the way to
- 30:49work. So, and actually that's what I've
- 30:51read that that's the best time to get
- 30:53fuel is in the morning
- 30:54because the fuel is cooler. The atoms are
- 30:58closer packed together
- 31:01and you get more fuel
- 31:03in your vehicle than you do if it's hot.
- 31:06Actually in the early morning
- 31:09hours after the fuel has had
- 31:11time to cool down is probably the best
- 31:13time. If you have a
- 31:14refrigeration unit that you can put
- 31:16over the top of the storage tanks that
- 31:18would help you even more. So anyway,
- 31:21that's kind of my bottom
- 31:23I have not improved my fuel economy by
- 31:27better driving. I have not
- 31:29improved it by really any
- 31:33means that I can see. The data does not
- 31:37bear out that oh and I
- 31:39also installed a performance
- 31:41distributor firewire 4.0 kit in the hopes
- 31:45that it would give me a
- 31:47better spark and give me better
- 31:50combustion of the air fuel mixture and
- 31:52basically you know give me
- 31:54more bang for the fuel buck
- 31:58and that did not occur. That did not
- 32:00occur on my vehicle now. We
- 32:03recently gave away a performance
- 32:06distributor firewire kit about a $200
- 32:08value 170 at least to a
- 32:12xjtalk.com member and show listener.
- 32:15In the chat room tonight, Weldman, I like
- 32:19to call him Weldman and he
- 32:21recently installed it on his
- 32:23Jeep. Kurt what year is he says grr he
- 32:29doesn't like Weldman.
- 32:30What year is your Jeep, Kurt?
- 32:34I think I'm saying your name wrong.
- 32:36Weldman's Jeep is a 1995
- 32:39so it's three years older
- 32:42than my Jeep and he was able to install
- 32:45his firewire kit and gap his plugs 0.054
- 32:51that if I recall his post correctly and
- 32:55he says he has received a
- 32:57increase in throttle response
- 33:00and I think he's very hopeful. Kurt is
- 33:02also getting pretty bad
- 33:06gas mileage. I think he's
- 33:07getting around 140 miles per tank of gas
- 33:11and Kurt is that a 20
- 33:17gallon tank or is it the
- 33:19what's the other one that they have a 16
- 33:2115 gallon I think so
- 33:23it's a 20 gallon okay.
- 33:24See I'm getting around anywhere from 215
- 33:28to 230 miles out of a
- 33:32tank of gas on my vehicle.
- 33:35So that's almost 100 miles to a tank more
- 33:40than what you're getting.
- 33:41Now I've pretty much always
- 33:43been getting that though and that didn't
- 33:45change with the firewire
- 33:46kit. Now I didn't gap my spark
- 33:49plugs. I think well you read the article
- 33:52that I wrote up on that
- 33:53most recently Kurt. I guess
- 33:55I had forgotten. I think that it is oh
- 33:59Kurt says he's at 142 as of today. How
- 34:01much gas do you have
- 34:02I mean what does it
- 34:03say on the fuel meter?
- 34:08Just waiting for him to type in his
- 34:10response. Oh wow well
- 34:13actually if I was sorry he Kurt
- 34:17Weldman responded with just over half a
- 34:19tank. So did you fill up
- 34:22right after you put the firewire
- 34:23kit on or had you already used some gas?
- 34:25He said no on Sunday. So I
- 34:29guess I don't understand.
- 34:31You filled up on Sunday and then you
- 34:35installed the kit or you installed the
- 34:37kit and then filled up
- 34:38on Sunday. I can't remember did you put
- 34:40the kit in on Saturday or
- 34:41you installed it yesterday?
- 34:42Okay so oh and the other thing I had
- 34:45posted up did you reset the
- 34:47ECM because you know you need
- 34:49to reset your ECM so it can relearn
- 34:51everything. Yeah because and I think
- 34:54that's a I think that
- 34:54was a correct statement that I made in
- 34:56that post. I mean you
- 34:58made a significant change
- 35:00to the ignition system and those of you
- 35:02that aren't familiar the
- 35:04performance distributor kit
- 35:05is a higher voltage coil and this isn't
- 35:09unusual this has been doing
- 35:10they've been doing stuff like
- 35:11this. People have been coming up with
- 35:13higher voltage coils and
- 35:16plug wires that are faster to
- 35:19move that that energy from the the the
- 35:21coil to the plug and hotter
- 35:23burning plugs and etc etc.
- 35:25That stuff has been going on for years.
- 35:27It's not some new
- 35:30pseudoscience thing. It does work. They
- 35:32use it in racing. So anyway the
- 35:34performance distributor kit
- 35:35basically is a higher voltage
- 35:37coil some high temperature plug wires.
- 35:40The plug wires are really
- 35:41nice and it allows you to run
- 35:46a greater spark and a bigger gap on your
- 35:49spark plug. Again giving a
- 35:51better larger spark to make
- 35:54hopefully to ignite the air fuel mixture
- 35:57more completely giving you more
- 36:01giving you more oomph for the buck. So
- 36:05Kurt has installed one
- 36:07installed a kit on his
- 36:08his Jeep and I know he's hopeful and I
- 36:11certainly am too that he's going to see a
- 36:14a mile per gallon performance. He says he
- 36:16already feels a seat of the pants change
- 36:19more power. Kurt what you have the 355
- 36:22gears. Kurt just says
- 36:25huge. It's a huge change.
- 36:28You have 355 gears in your axles right
- 36:31and what size tires? Well I love that
- 36:33complete silence when
- 36:34I stop talking. So he's got 30 inch
- 36:37tires. So he's all about if I remember
- 36:41right that's about three
- 36:42inches or an inch and a half on either
- 36:45side of the tire bigger than
- 36:46a stock tire because I think
- 36:48stock tires are 27 inch. Yeah 2.5. Okay
- 36:52so well that's good. You
- 36:54know it's amazing it's just
- 36:56amazing that you are getting that bad of
- 36:58gas mileage on 30 inch
- 37:00tires. Man anyway I don't
- 37:04want to go I have a bunch of questions
- 37:05I'd like to ask you and probably
- 37:07redundant questions that
- 37:08you've been asked like changing o2
- 37:10sensors and so on so forth. I mean I
- 37:13firmly believe that a bad
- 37:15o2 sensor is could give you bad gas
- 37:18mileage. I mean if it's not
- 37:19giving the most accurate data
- 37:21to the ECM the ECM is not going to be
- 37:24able to determine what the
- 37:27proper air fuel mixture is
- 37:28going to be and so on and so forth. Yeah
- 37:30that's the other thing
- 37:31that was my question. Wellman
- 37:33says no codes question mark and that was
- 37:37that was what I always
- 37:38thought if it's not throwing a code
- 37:40if the check engine light's not coming on
- 37:42your dash then the o2 sensor must be okay
- 37:44and they said not so that the o2 sensor
- 37:48can be giving erroneous
- 37:50information but it's still within
- 37:52the the acceptable limits for the
- 37:55computer to say okay you know I'll deal
- 37:58with that and I don't know
- 38:00if that means that it has the ability to
- 38:02adjust well enough to not to
- 38:08significantly impact the
- 38:10mile per gallon that you get or if it
- 38:13just means it doesn't matter it could be
- 38:15that it just it just
- 38:16doesn't matter it's just not that
- 38:18critical and it could be the latter and
- 38:21that might be why when I
- 38:22change the o2 sensors and I've changed
- 38:24the o2 sensors several
- 38:25times that that's why it didn't
- 38:28make a difference. Now I will add looking
- 38:30at the data over the last
- 38:33well in 2010 I did see a on
- 38:37average a decline in my miles per gallon
- 38:42by maybe two tenths of a of a
- 38:45mile per gallon. It probably
- 38:47is closer to a tenth and like I said
- 38:50earlier I think that you
- 38:51have to measure this over a long
- 38:53period of time to really get a sense of
- 38:56what your your fuel mileage
- 38:57is because it is it varies
- 39:00drastically. One of the things that I
- 39:02have noticed though is if you
- 39:04look at how many miles you are
- 39:07on a tank of gas that seems to be and
- 39:11it's probably it's
- 39:12probably the difference in the
- 39:15decimal point numbers as opposed to the
- 39:17mile numbers but just not
- 39:20really thinking about it I guess.
- 39:23You know that always screws things up
- 39:25when you think about it.
- 39:27I've noticed that the anyway the
- 39:28number of miles on a tank of gas is
- 39:31pretty much always the same. I know it's
- 39:34going to be 200 miles
- 39:36at least and it probably is going to be
- 39:39230 if I really want to push
- 39:41it. I mean I've seen it 235
- 39:43and I guess I just get a little nervous
- 39:45and when I get to around 210
- 39:49212 it shows empty and you know
- 39:54I don't carry a fuel can on my Jeep so if
- 39:58it if it stops running then
- 40:01I'm walking or I'm trying to
- 40:04a gasoline station. So there's just so
- 40:06much that you you know how there's so
- 40:08much you want to chance
- 40:09it. So anyway bottom line is over three
- 40:13years or almost three years
- 40:14here in two months it'll be
- 40:15three years of collecting mile per gallon
- 40:18data. I have seen no
- 40:21significant change in my mile miles
- 40:25per gallon either to the positive or to
- 40:27the negative with the
- 40:29exception of changing the
- 40:33front and rear differential gears going
- 40:35from 355 stock to 456
- 40:40not stock. I would be very
- 40:42interested in knowing what it would be
- 40:44like to be on 410 gears. Now what I'm
- 40:47going to be doing here
- 40:48in the next few months maybe just a month
- 40:51or so just depends is
- 40:54changing the tires. I'm going to
- 40:56be going from the 32 11.5 by 15 to the
- 41:02the new KM2. I have the KM1s
- 41:06mud terrains on my vehicle now
- 41:08which I'm sure doesn't help the gas
- 41:10mileage because of those those big lugs.
- 41:13But I'm going to be going
- 41:14to the KM2 because they don't make KM1s
- 41:17anymore otherwise I'd just
- 41:18be getting another shot of
- 41:19those. But I'm going to be going to the
- 41:2133 by 12.5 by 15 tires. Now the KM2 at
- 41:27least in my layman's
- 41:29opinion is not even though they're mud
- 41:31terrain they they are not
- 41:33as aggressive as the KM's.
- 41:37The the lugs are closer together and they
- 41:41they look to me to be more of a
- 41:44all terrain tire. Now they do still have
- 41:47all terrain BFG all
- 41:50terrain tires and they're not
- 41:52as aggressive as this tread pattern. So
- 41:55I've heard that the the KM2s
- 41:57are quieter. I've heard that the
- 41:59KM2s I've heard they work well so you
- 42:04know maybe I'm hoping it's
- 42:05just it's just computers. Able to
- 42:08the same response from a better tread
- 42:12pattern. And I suspect that it may
- 42:16balance out the since I'm
- 42:17going wider an inch wider on the tire
- 42:20it's going to be more contact between my
- 42:24vehicle and the road
- 42:25which is going to mean more friction
- 42:27which should mean a drop in I mean logic
- 42:29says that it should be
- 42:31a drop in miles per gallon. And I will be
- 42:34changing out the the
- 42:35gear in the speedometer gear
- 42:39in the transfer case to so that it will
- 42:41measure the measure the
- 42:44distance and therefore the speed
- 42:46correctly. And so my mile per gallon
- 42:48should still be accurate and
- 42:50and I'm not going to drive it
- 42:52without changing out that gear. I'll get
- 42:53the gear before I get the
- 42:55tires and I'll have it ready and
- 42:56I'll swap it out or I'll do it shortly
- 42:58thereafter. So it would be a very small
- 43:01statistical bump on the
- 43:02the mile per gallon radar even if I
- 43:05change it out a day or so later. So I
- 43:09will be sure and correct
- 43:10that but it's very interesting to see
- 43:12that nothing has made a change and I'm
- 43:14also interested to see
- 43:15if it's going to make any any real change
- 43:18with a larger tire. Now I
- 43:20was thinking about going to a
- 43:2135 inch tire and for two reasons. I like
- 43:25the you know to me the bigger the tire
- 43:27the better it looks.
- 43:29And also too with the 35 inch tire I
- 43:32would be closer to the
- 43:35right ratio with the 456 gears.
- 43:39I'd be very close to stock gearing. In
- 43:42other words I would be very
- 43:44close to the same gearing I was
- 43:47with the stock tire and the 355 gears in
- 43:52the in the axles. The
- 43:54problem with putting the 35 inch
- 43:56tires on these axles the Dana 30 up front
- 44:00and the cross array 0.25 and back is it
- 44:03puts a lot of stress
- 44:04a lot of torque on those axles and on all
- 44:07the parts. It also
- 44:09puts more stress on the
- 44:12steering box and even how it mounts to
- 44:14the to the unibody. So there's a lot of
- 44:17things that you really
- 44:18need to do to beef up your your Jeep to
- 44:22run 35s or 36s or 37s or or
- 44:26whatever. But people have found
- 44:29they can pretty well get away with
- 44:31running 33 inch tires morning noon and
- 44:34night and the engineering
- 44:38of the Jeep Cherokee is sufficient enough
- 44:41to to to do that. Now
- 44:43that's substantial I mean
- 44:44that's I think that's a good four what is
- 44:47that three four five
- 44:50that's that's five inches wider
- 44:53or taller I should say diameter tires
- 44:56than the stock tires. So you
- 44:58know that's giving you another
- 44:59two and a half inches of ground clearance
- 45:01basically. So that's
- 45:02significant it really is a 33
- 45:04inches really is a big tire and I
- 45:08wouldn't think that just a half inch
- 45:10bigger on either side of the
- 45:11the 32 that I have would would make
- 45:15physically look like that big of a
- 45:16difference. But I was
- 45:19went off road with a XJTalk member and
- 45:21friend about a year or so
- 45:24ago and he had just gotten a
- 45:26set of KM2 33 inch tires and when I saw
- 45:30them I thought they were
- 45:3135s. They were just huge and
- 45:34looked so much bigger than mine and they
- 45:36were just a an inch
- 45:38taller and an inch wider. So
- 45:42I would like to see what what it would do
- 45:45and who knows I might be
- 45:47able to run across somebody on
- 45:48the site that has some 35 inch tires that
- 45:51I can just swap out and
- 45:53and drive them for a week and
- 45:56see what it would be like from the
- 45:59standpoint of gas mileage
- 46:02and that heat creep problem
- 46:03I was talking about. So I don't know I've
- 46:06talked a lot about about
- 46:07the mile per gallon a lot more
- 46:08than what I thought I was going to and
- 46:10actually I thought we were
- 46:10going to have a short show today
- 46:12but I guess I got on a rant. Let's see a
- 46:16triple back over here to the
- 46:17the chat room and catch up.
- 46:20So let's see I think Weldman was asking
- 46:23me a question. Tony do
- 46:24you have a six inch on that
- 46:26red thing? I would assume that you're
- 46:28referring to the the lift
- 46:30it's a four and a half inch lift.
- 46:32So yeah 27 inch tire I think is the stock
- 46:35size. I'm just seeing
- 46:37VW Fool says they are
- 46:40say beefy as hell though they are ran
- 46:43with 456 and 33s you get the same mpg.
- 46:47I'm trying to read here
- 46:49VW what do you mean the same mpg is what?
- 46:53The 456 is with the
- 46:5533s you get the same mpg
- 46:56a mile per gallon is is running what?
- 46:59Okay well that's interesting he says
- 47:02versus 355 gears and
- 47:05225 or sorry 235 I think that's a metric
- 47:09measurement of the tire. Oh with Dana 60s
- 47:12as stock axles. Yeah but the Dana 60s and
- 47:15I guess I'm going on going
- 47:16against the thing I've already
- 47:17said the Dana 60s are really heavy and
- 47:20boy you know just by their nature you
- 47:22have to put a bigger
- 47:24on them because if you run data 60s with
- 47:27small tires you know you're
- 47:30you're defeating the whole
- 47:31purpose of lifting lifting the vehicle to
- 47:34start with because you
- 47:35want to get that pumpkin that
- 47:37differential higher off the ground and
- 47:40the Dana 60s are just huge
- 47:43pumpkins and they're going to
- 47:45be close close to the ground so I think
- 47:47you need a 35 inch tire
- 47:49minimum on a Dana 60. Of course
- 47:52nice thing about the Dana 60 I think you
- 47:54can run pretty much
- 47:56anything up to a monster truck tire
- 48:01it's going to take it 54 inch tires I
- 48:04don't think were a problem
- 48:06for Dana 60s and that would just
- 48:08be you know incredible it would be a lot
- 48:11of fun to have a vehicle with
- 48:14a big lift and big tires and
- 48:18some some badass axles it's certainly not
- 48:21going to be a trail
- 48:22vehicle or climbing vehicle like
- 48:24what the the Jeep Cherokee is so I don't
- 48:27know if you guys I think
- 48:29many of you realize that maybe
- 48:30some that aren't into the off-road thing
- 48:33just you just see the
- 48:34lifted vehicles on the street.
- 48:37When you see a truck that's lifted a good
- 48:40foot two foot in the air
- 48:41and has these massive tires
- 48:44on them but it is very impressive very
- 48:46cool to look but for all
- 48:48intensive purposes those are
- 48:50road warriors you aren't going to see
- 48:53those off-road and if
- 48:54you do see them off-road
- 48:56it's going to be mud and even at that one
- 48:59of the vehicles get when
- 49:01the vehicles are really heavy
- 49:04like the the big Ford 350s and stuff they
- 49:08get so heavy that you
- 49:09it's not a good idea to run
- 49:11because they're going to get stuck no
- 49:13matter what size tire you have on there
- 49:15and now you've got a
- 49:16nice 70-80 thousand dollar vehicle stuck
- 49:20in the mud and it's so damn
- 49:21heavy and it's and and with
- 49:22the addition of the the friction of the
- 49:25mud you got something that
- 49:27you can't you can't put enough
- 49:29stuff on it to pull it out so you know
- 49:32there really are just road warriors and
- 49:36they're a lot of fun.
- 49:36If I get an opportunity to get another
- 49:39four-wheel drive pickup I
- 49:41will but it is different from the
- 49:43Jeep. The Jeep is a very fun vehicle to
- 49:48take off-road to drive on
- 49:49the street off the street and
- 49:52it's like it's kind of like having a goat
- 49:54that doesn't eat the eat
- 49:55the cans it will pretty much
- 49:58go anywhere any little spot you want to
- 50:00go and of course I've been looking at
- 50:03these Suzuki Samurai's
- 50:05talk about small and and going places
- 50:07they are you're talking
- 50:08about something that's
- 50:10maybe half the size of a Jeep one of the
- 50:13Wranglers. Wow those things are pretty
- 50:16amazing I can see how
- 50:17that would be a lot of fun to drive those
- 50:18things around. You get the
- 50:19you get a good lift out of it
- 50:21and get some some good sized tires plus
- 50:23the they're very short
- 50:25and narrow and can they seem
- 50:29to be able to go go lots of places as
- 50:30well. So yep I'm not
- 50:32going to be able to get to the
- 50:34to the Jeep cooling. I'll suffice it to
- 50:37say I've changed
- 50:39everything on my cooling system
- 50:42with the exception of the heater core
- 50:44which isn't directly the cooling system
- 50:47but the coolant does
- 50:50through it. So I've changed all that and
- 50:54upgraded all of it. Yeah
- 50:57well the hoses are still made of
- 50:59rubber and you know they're still basic
- 51:02hoses they have been changed I
- 51:03won't call that an upgrade but
- 51:04I have modified the the rest of it. It
- 51:07does cool much better but as
- 51:10I was saying earlier in the
- 51:11program I do have this issue with heat
- 51:12creep going down the highway the cooling
- 51:16system is not capable
- 51:18of keeping up with the amount of heat
- 51:20that's being generated by the
- 51:22engine and traditionally that
- 51:24means that the traditionally that means
- 51:27that the you're not getting
- 51:30enough airflow through the
- 51:31radiator and certainly the the the custom
- 51:35bumper winch and off-road
- 51:38lights would be would seem to
- 51:39be the culprit for that however and I'm
- 51:43not saying they're not not
- 51:44keeping the airflow from going
- 51:46through I'm sure they are but I was
- 51:48having this issue before
- 51:50I changed up that bumper.
- 51:52But I can drive off-road, crawl, a lot of
- 51:57torque, a lot of
- 51:57horsepower usage, off-road,
- 52:00very low speeds and running the air
- 52:04conditioner which just seems kind of
- 52:06counterintuitive but you
- 52:08know I'm a fat boy I don't want to be out
- 52:10there sweating making my
- 52:11own gravy. So driving around
- 52:14air conditioner blaring 9500 degrees air
- 52:18temps and had no problems with it
- 52:20overheating. So all the
- 52:22all modifications that I've made
- 52:24definitely helped but I still got to fix
- 52:27this heat creep issue so
- 52:28that I can actually drive it on the
- 52:29highway and of course that
- 52:30was one of the reasons why I was
- 52:31looking at doing the 35 35 inch tires to
- 52:35see if it was an RPM related issue. Get
- 52:39the RPMs back down to
- 52:412200 at 70 miles per hour and I think
- 52:44that's right. I think 2200
- 52:46RPM and 2300 is about what
- 52:50it was when it was stock. It's another
- 52:52one of those things
- 52:52before you start making changes
- 52:54make notes of things because then you
- 52:56wind up having to go back
- 52:58and ask people what their stock
- 52:59vehicle does. I dearly wish I had done a
- 53:03good gas mileage measurement
- 53:07on my stock Jeep especially
- 53:08when I first got it. You know the fuel
- 53:10was a dollar something a
- 53:12gallon back then and it just
- 53:13really didn't matter. So Weldman is
- 53:15screaming at me here in the chat room he
- 53:17says Tony Reed let's
- 53:18see. Weldman says that I don't know how
- 53:22far back I'm supposed to go Kurt but
- 53:23Weldman says Tony my
- 53:25temps went down with the firewire kit and
- 53:2837 exclamation marks
- 53:29after that and yeah I didn't
- 53:31see that. I didn't see that occur. Let's
- 53:35see always on four trucks and Jeeps and
- 53:38VW water cooled cars
- 53:43Mustangs as well. Okay VW Fool says I
- 53:47can't get my temps over 160 not that good
- 53:51need to change up my
- 53:52T-stat to a 180 or 190. Yeah everything
- 53:56I've read as far as miles
- 53:58per gallon you want to go with
- 54:00the 190. I think the 190 is the stock at
- 54:04least on the the 98s the HO
- 54:07engines 190 degree thermostat
- 54:10is the stock and you do want to and I
- 54:13learned the hard way a thermostat will
- 54:16not lower your temps.
- 54:17It'll just keep the the the coolant
- 54:20temperature cooler longer once it once
- 54:23the temperature rises
- 54:26the thermostat is open and it doesn't
- 54:27matter it's going to run at
- 54:29whatever it's going to run at so
- 54:31it just means it'll open sooner and it
- 54:33will stay cooler longer but
- 54:36if you're if you're going any
- 54:38place over any distance it's going to
- 54:39rise to whatever whatever
- 54:41the value is whatever the
- 54:42balance between how much heat the the
- 54:44engine is creating and how
- 54:46much how much you're able to cool
- 54:48that coolant as it moves through the
- 54:50radiator and the water
- 54:52jackets and so so forth so
- 54:54I understand it now thermostat just
- 54:57delays the inevitable I
- 54:59should say and I certainly saw that
- 55:00because I tried it I put 180 degree
- 55:02thermostat on mine and it basically
- 55:06served to help me freeze my
- 55:08ass off during our winters and remember
- 55:11our winters aren't very
- 55:12very bad here I mean we're
- 55:13talking about some 38 degree days 40
- 55:15degree days and man it was
- 55:17cold and cheap it was really cold
- 55:19in the jeep I know I'm a big baby I don't
- 55:22know what cold is but I
- 55:24do like the cold it's very
- 55:26pleasurable not breaking a sweat getting
- 55:30out of the jeep and walking
- 55:31into the house but it gets a
- 55:33little a little tiresome whenever you're
- 55:38driving an hour two or from
- 55:39work to not have the heat in
- 55:42the jeep I kind of learned that that one
- 55:44that 190 I keep wanting to
- 55:46say 195 but I believe it's 190
- 55:48degree thermostat that one made a big
- 55:51difference as far as keeping the jeep
- 55:53nice and warm and even
- 55:55at that with all the the modifications I
- 55:57made to the cooling system
- 55:58it takes a little while longer
- 56:00to heat up to and get some some nice
- 56:03temps out of the out of the heater so
- 56:08guys I I did a whole
- 56:10hour tonight I was thinking I would be
- 56:11doing this for about 30
- 56:12minutes but I appreciate the the
- 56:16people that showed up in the chat room
- 56:18and the interaction it's
- 56:19always fun I enjoy the I enjoy
- 56:22the show personally a lot more whenever
- 56:25we have some some folks in
- 56:26the in the chat room so thank
- 56:28you very much and and Kurt my apologies
- 56:31for not getting that that
- 56:32firework hit to you sooner
- 56:34but you got it and you are having fun
- 56:37with it and and all it cost you was a
- 56:39little time to record
