Jeep Wrangler YJ Thermostat Replacement

[@UlimateWarriorz]

I'm glad your channel exists. I just got my hands on a 90 YJ and your videos help me be able to do my own servicing and upgrades on it. Thank you. I thought changing my thermostat was going to be a pain, but it was super easy and I knocked it out in an afternoon.

[@DonBrujo027]

Best yj channel around here. Thanks!

[@Wheresmycar89]

One of the only guys videos I trust on KZbin lol

[@AstanaxKnight]

I had to remove the radiator to install an aftermarket a/c system with condenser and fan. I got it all back together, and the temperature went from 210 on the gauge to 265 degrees before suddenly moving back down to 210 and staying there. I read the thermostat sticking was the problem. So I am glad to of found your video and the coolant hasn't even cycled ten miles yet. I figured I would nip this in the bud before it becomes a problem further down the road.

[@JeepSolid]

Great! I'm glad you found it helpful.

[@AstanaxKnight]

@@JeepSolid I did happen to notice that, for the gray RTV sealant for thermostats, the directions said to wait 24 hours before refilling. I don't know if that black RTV sealant you used required the same 24 hours. Other than that, the gray sealant behaved the same way in terms of holding the thermostat in place while I put the housing on.

Hi jeep solid ....COOL!!! Great video ! I learn a lot from your videos . You saved me a lot of money so far . ( I like the nap time )

[@pierrer6605]

Thank you for this video ! 😊🇫🇷

[@willburk]

Great video, thanks!

[@jeffchappell4856]

Another good video! and great tips on the process. Good idea to go Grade 8 bolts just to ensure they never snap again. doesn't hurt to use never seize on the bolt shafts where they got stuck last time!

[@JeepSolid]

+Jeff Chappell yeah, anti seize is a good idea as well

[@franciscoloriamafud8614]

Hey! Thanks for the video! Very helpful and necessary!

[@urighht]

Awesome video dude..ha i new there was a reason for that little whole! So you putting lube on the thermostat to make it stay and not leak was why i found your video! Question my replacement thermostat came with a rubber “O” protecting type situation around the rim! Is it for a reason or part of the packing? Thanks ahead of time!

[@JeepSolid]

I'd look up images of that brand. See what you can find out. I'd guess it's part of the thermostat

[@marcosmata4625]

Thank you so much what a wonderful video it help you so much on my repair

[@BMWJourney]

Yup; as I’m doing my water pump I decide to do my thermostat as well once I was done and what happened the bolt came clean off just like yours, and nowhere could I find the top bolt ended up going with a 1/4th inch shorter bolt which I suppose won’t cause a problem since it’ll be in there either way. Great video thank you!

[@JeepSolid]

yeah, what a pain.

[@AstanaxKnight]

Measuring mine to the old, unbroken bolt, it was 2 1/2 inches. I could not find the 2 1/4th inch bolt either, so I got both 2 and 2 1/2 inches to measure up.

[@joelmaealiuaki7450]

Very helpful. Question for you. Own a 2000 jeep wrangler, replace the thermostat but the bolt hole on the bottom is stripped and have a bad leak. Any recommendations, what would you do? Thank you for your time ,aloha🤙🏽🍍

[@nathanmciver6496]

Right away! This is what I'm talking about! I can already tell this is the solution! I just figured the automotive industry wouldn't be so stupid and when you buy a gasket it is quality and will work the first time as it should!!!!! This isn't helping that people have to make money of knowing cheap tricks (unrelated) At least your video seems to be helping and this would be the resolve I'm sure(a gasket that seems to be the correct width and proper sealant just incase), I might have to order a new thermostat housing to be safe! Not sure yet. Really don't see a need! Just not a fun job to be direct! I appreate the humor within your videos. Lmao? You said felpro? I don't think so! That's the gasket I used and it was shit, the other gasket looks like the 30$ gasket, also not colored the same 35630 was the part for the felpro gasket Grey and red lines around the gasket for the one I ordered and tried! It ripped even with perfect seating, so not likely the r.t.v would have worked with this gasket! This was for a 2000 jeep wrangler 2.5L Altought the gaskets look the same at least for the fitment! Yours looks like 30$ edelbrock gasket

[@ace1gun]

Do you have to remove the radiator to replace the water pump??

[@CT--us4mc]

Just did this. How long does it take for your jeep to start sort of regulating its temp again? I started off and it would get really hot. And now it's starting to come back down again. Not sure if it's gonna stay like that though.

[@jamessnook15]

I was wondering if you ever had an issue with your temperature gauge? I have a 94 YJ. I pulled the gauge cluster out to replace the light bulbs to LED. When I put everything back together my gauge began to give me problems. So I replaced the gauge. Still didn’t give me a good reading. Jeep would sit all night, and still read 210. I finally replaced the engine coolant temp sensor and now the gauge it maxed out to the limit by driving less than 5 minutes. Any suggestions? I’m thinking about wiring in a gauge through the fire wall straight from the temp sensor. I have replaced the thermostat and the sensor that goes to the ECM. I have no check engine light.

[@charlesnosbisch922]

Which temperature thermostat should I use for my 93 yj 4.0 didn’t realize there were so many options

[@Dozier717]

I've got a 1997 Jeep Wrangler SE with a 2.5 4 cylinder engine; I need to put a thermostat in it badly. 170k miles on the housing but hopefully, the bolts won't break!!

[@JeepSolid]

Yeah. Mine broke as I show on video. What a pain it was.

[@kevinengland4675]

Another great vid man 👍

[@williamowens1325]

Did your thermostat have the weep hole and would you use one that doesn't have a weep hole. I've seen recommendations on yj forums of drilling a weep hole but there's no way I'm doing that as it would void the warranty. But let me know what you think. Got to do it tomorrow

[@colossalman]

/thanks, I would not have known to use RTV!

[@GerardoLopez-cd9mb]

Hi good video I did everything and it seems fine but my temp gauge is now fluctuating between 210 and 195 it won’t stay steady any suggestions would help thank you

[@billyshelleynorth]

Do you think this is something I should try to attempt? I have no experience working on vehicles, but I was able to figure out how to change spark plugs, wires & distributor cap last month...... I'm trying to figure things put!

[@jerrygonz7708]

Good Evening, I’m in the process of ordering the parts you have listed for my 94 YJ 6cl and all the parts match except for the ACDelco 12TP1E Professional Engine Coolant Thermostat. Do you think that’s an error from Amazon?

[@hellohello8556]

Nice cat.😍👍

[@davidpartida3856]

Good tips thank you👍

[@JeepSolid]

Thanks for watching!

[@davidwehman2673]

I have a YJ, freshly rebuilt motor and runs really cool, to the point where the heater barley works and run around 120-140 degrees. Do you recommend where the weep hole on newer thermostats should be oriented?

[@robertoldham2122]

Does anyone know where he got the bolts I’ve been to advanced an everywhere an know one has them ??

[@jaygee291]

Great video, helped me immensely!! I noticed a tiny leak after I was done near the housing. I read to park on an incline in order to fill the engine block and have coolant pass through thermostat. That sound right to you??

[@JeepSolid]

Paring on incline is fine. Just have to make sure you're getting all the air out and topping it off as you go.

[@jaygee291]

@@JeepSolid thx again!! It worked. Its getting overheated still but takes a lot longer. Im thinking it's the water pump maybe. Heat is working fine too.

[@LoL_LittleBigEddy]

Thanks dude

[@JeepSolid]

No problem.

[@builtnotbought7787]

Lol my yjs engine is greasyyyyy so I doubt I'ma break any bolts on it... Hopefully

[@MrSlickmonster6973]

I have a question... the manual says it takes around 2.6 gallons of coolant. It only took 2 gallons. Any ideas? I have a 92 wrangler with a 4.0L

[@JeepSolid]

Probably want completely empty. Just make sure you burp all the air out

[@MrSlickmonster6973]

@@JeepSolid ok. thanks. Love your channel

[@sam6009]

Loved the video, just wished you had put the part about the purge hole in at the same time as placing the thermostat in. I was doing this step by step and got to end hoping I had the hole at the top.

[@JeepSolid]

They don't all have purge holes. Easy to add one if you want.

[@sushil1983]

with the thermostat that you are installing I saw that you don't have a purge hole in it, how should we purge a thermostat that dont have that hole to purge the air?

[@kevinengland4675]

sushil1983 he explains at the end of the video if you want you can drill a purge hole yourself if you like other wise you have to wait till the thermostat open I believe if I remember correctly.

[@sushil1983]

Thanks Kevin, yea I made that question before ending the video. But thanks for the suggestion. I will do that

[@JeepSolid]

+sushil1983 yeah, bleeder is helpful, but not absolutely necessary. Thanks for watching!

[@PahjoDesigns]

where do you purchase your grade 8 bolts from?

[@JeepSolid]

Ace Hardware or Hubbards. Those are local hardware shops where I live.

[@PahjoDesigns]

JeepSolid - I have Ace Hardware. I’m in Destin Florida. Thanks for the response. Your videos have helped me tremendously.

[@alonzomendoza5393]

I need to change mine to a 195 before winter so I don’t freeze my ass off this winter lol

[@craiggeratorbest9323]

You hide 1 important part removal, some how the fan belt was removed before you started on the other parts!!!!!!

[@nevermeanttobuild1514]

It’s definitely in the video…

[@heinzkitzvelvet]

Ok. I just used this video to change my thermostat. The old thermostat was stuck open. Temp wouldn't come up past 120. Very cold. Installed the new Tstat. NOW, the temp gauge hangs out around 240-250°F, which scared the hell out of me. So I made certain that it was fully topped off with antifreeze. Gauge still running hot. Couldn't figure it out. So I decided to put my digital temp gauge on the Tstat housing. It says 180-185°. Does this mean the temp sensor is faulty? Or possibly the gauge? The heater gets really hot. In my experience, if the car is overheating, the heater will turn cold, but it's not. It's not bubbling or steaming or running bad. So I think maybe it's not displaying the correct temp.

[@davidschlabach8817]

same for 2.5l?

[@JeepSolid]

Yep 👍

when did you start you youtube channel?

Dude you're killing it! I hope you're able to gain some steam!

[@JeepSolid]

Thanks Bud! Slowly but surely..

[@anitaramospiper7199]

What’s the sensors name

[@davidjessee7701]

Never use a thread sealant on temperature sensor as it may impede the grounding of the sender..

[@MrPiimpslap]

Dont have to worry about that for the sensor in the thermostat housing, it is a 2-wire sensor for the ECU. The one for the gauges in the rear of the head could have an issue if doesnt get a proper ground.

[@scottsmith6571]

What temp gauge 175 ?
