3.6 Pentastar Jeep Wrangler Unlimited Rubicon JKUR Oil Cooler Replacement How To Oil Leak Fix 

Check out this other great oil cooler video for more info and details! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-E6klsFThvTY.html Oil cooler to engine block is 106 in-lbs Upper intake bolts 89 in-lbs Lower intake bolts 106 in-lbs Thanks for the view!

I want to thank you! Your video got me thru the install in about 3 hours and been running great with no leaks for a couple weeks now. Great video, saved me $$. 👍🏼

Just finished this job a few hours ago, thanks for making the process alot less daunting, no leaks so far and keeping my fingers crossed with a keen eye watching for any warnings! Thanks a bunch!

Hey man, thank you so much for making this video. I’m no mechanic and this was the most advanced auto repair I’ve ever attempted. I went slow over two days and did it with no leaks or codes! Besides the injector plugs being designed by satan, I got my dorman unit installed. The only thing I broke was the pcv vent tube while taking it out of the clamp. I fixed that with a short section of rubber tubing joining the snapped tube and was good to go. Thanks again for expanding this layman’s abilities!

Thank you so much ! I follow your video and change my cooler, took me 3 hours and it works like new. You saved me $1000

If I could pay you I would, I literally watched this video the whole time I was doing it

After experiencing coolant spilling over my bell housing and not finding ANY hint of where it was coming- my research pointed to the oil/coolant filter housing. After watching a few videos, I’m really appreciative that you provided yours. This, to me, is an excellent guide. You did a great job! Thanks again!!

This is a brilliant video, and the most comprehensive I've seen on this subject. I'm confident I can replace the oil cooler on my Wrangler tomorrow. Thank you!

Wow you made that look Super simple and really not that complex , as long as you keep items in order and don’t forget to hook up. I was told it would take a mechanic 4 to 6 hours and cost $1100 with parts and labor. You just blew that scenario out of the water. Thanks and props to you it doesn’t look that daunting anymore.

Fantastic explanation. I appreciate taking the time to detail what each thing is as well as demonstrate the removal. Seriously. Helps me with my sister in law’s Jeep.

Dam man this is one of the most comprehensive and clearly outlined instructional vids I’ve watched, thank you.

Did this with caravan, seems the same idea. Appreciate your time there.

Thanks! This is the second time I will need to replace it, but this time it's not under warranty. This video was very good, so I am going to attempt it myself.

great video so nice to see it as you were well organized and stuck to exactly the point of showing the work and getting it done.

Worked perfectly ! thanks to your video was able to complete in a few hours, and changed the plugs while the intake was split. You Rock !

Part will be here tomorrow and I'm dreading this job. Nothing ever comes off in one go for me. Thanks for this video!!

Great tutorial, took 4 hours and change for me including a significant amount of cleanup and went ahead and changed the thermostat while there.....Figuring out how to get the fuel pump connectors off was my biggest problem....Much patience was needed but little was exercised! LOL

Excellent video tutorial. Thank you so much for this. I was able to complete in less than 4 hours. I also changed the spark plugs while I was in there. Looks like you did this in about 20 min. Nice work!!!

Man one of the best videos of this fix.

you are a good man. Thanks for the video. A friend of my wife's has had some real bad luck. Her apartment was flooded in the hurricane, and then she moved into a mobile home only to find water damage, then her jeep started to randomly overheat. Looks like the dealership used stop leak to seal the oil cooler rather than fix it under warrantee. I'm going to attempt it tomorrow. You saved her over $1,400

Thanks. This was very helpful. I had the upper intake off before but not any further. Made it easy to understand. The flip on the intake is great.

Well, after studyinig your videos intensely, I replaced my oil cooler this afternoon. Connectors & tabs are the most challenging part IMO. Big thanks Tyler for putting this tutorial together.

Fantastic video, thank for making it. I am going to be replacing my oil cooler next weekend so this help tremendously.

Thank you, great video, the dealer wanted $1800+ to do that. My warranty ran out in January (it's now April). I do believe I can do this!!

Thanks for the most informative, detailed, and well edited video. Now I know what all is involved. I thought about doing this repair for a friend's low mileage 2015 Wrangler, but it looks like more than I want to tackle. (The aftermath of COVID, the brain says "We can do this! The body says "No way!")

Getting ready to replace this part for the SECOND time on my 2015. Thinking of doing it myself this time. So, thanks for posting.

Hey, thank you for this video. I had no mechanical experience and I followed every step in this video and I was able to replace this part.

Just wanted to let you know that this video was extremely helpful. I watched this step by step and it made it go SOOO easy. Thanks for sharing. I did like and subscribe to your channel.

Awesome video not so scared anymore if my warranty doesn't cover it thank you!

Thanks so much for your video ! I followed your video and changed the oil pressure sensor switch as it was causing a check engine light from time to time which would not allow my granddaughters jeep (college student) to pass the state EPA inspection? Thanks again as we were able to save the $1400 dollars the dealer wanted to replace it and apply it towards a semester costs of her education.

I've got a TJ with the 4.0... what a great engine !

Hello, thank you very much for the video, I have the same problem in my Wrangler 3.6 year 2014 and I did not know what was happening. greetings from Coyhaique CHILEAN PATAGONIA

Bro, thank you very much! I didn't find a suitable video in Russian, in your opinion I did everything without any problems! Thanks again! This car doesn't like our frosts)

Super helpful! Thank you so much for putting in the effort to create this how to masterpiece.

I just did this job. Took me a few hrs. A couple of tips: Get that clip removal tool he has. There are A LOT of clips in this. Disconnecting the fuel injectors was the most difficult part. Also, contrary to what has been said, it is very easy to drop stuff into the engine so take care to make sure that doesn't happen. For removing the lower intake manifold: I disconnected driver said fuel injectors first, loosened all the fasteners, wiggled the manifold, and removed the pass. side injectors (they are the ones buried under all those hoses). Also, I didn't have that rush of coolant that he used the pinch of pliers on the back of the oil cooler for, some coolant came out but nothing significant (maybe I'm low?)

Nice video! My daughter’s boyfriend and his father did this on her 2015 Jeep JKU tonight. Wish I was there to do it. I thought it was more daunting, but you made it look easy. If ours ever lets go on our 2012 JKU, at least I know what to expect. Again, nice video!!! 👍🏻😎

Thank you so much. I followed this video and I just finished the job. The hardest part was dealing with the passenger side and the connectors on the back of the oil cooler. I wish I bought a power ratchet as well. You save me a 1000 dollars man. Thank you. I put the upgraded doorman metal part in. I did get a p0113 intake air temp code. I clean the TB so I wonder if I damaged the sensors in the tube.

Great Vid Tyler. I am trying this weekend to do this. Shopping for some hose pinch pliers and hose clamp pliers now.

I can’t thank you enough for making this

Awesome video. Thanks so much for the details.

Those M12 stubbies are the best thing ever

Excellent video brother. I went with the aluminum replacement on our 2015 Wrangler. I thought maybe it was the housing itself that was the issue being plastic and the fact we bought it used. I always torque the oil filter housing but it turned out the seals on the bottom were the issue. Anyone with a 3.6 with 100000 miles should probably just replace it. Thanks again

That was really a 20 min job? Man you made this look extremely easy. I think I feel confident enough to tackle this myself.

Fantastic video!

Awesome! I learned so much from this.

Phenomenal video man!

Awesome vid! Definitely confidence inspiring.

Great video. I've seen a few of these done now and yours doesn't look as daunting as others have made it out to be

Great video and well explained!

Good video with explanation...few tips doing this DIY will save you $$$ Take it easy on electrical wires clips and ensure the bolts are tightened to manufacturer specified torque using star pattern. Replace the coolant :) good luck

Thanks a lot! You removed those fuel injector red clips and plugs in about 2 sec each........I broke 3 and fought them for an hour.

Thank you! Got er done today. I am a banker with limited mechanical know how. I equate my advancement today to a pimple popper becoming a brain surgeon. Thanks to your great video!

This video was extremely helpful!!! My Housing was not cracked but the gaskets on the bottom of the cooler were leaking oil.

First off, Thank you so much for this video! It helped me so much fixing a way too common in all 3.6L engines. Second, I do caution novice DIYs on attacking this themselves. There are many frustrations that you will run into and you will question your sanity a lot. Before starting make sure you have socket extenders, some of these both are just tough to get too. Make sure you have no where to drive too for a few days because it may take you more than just one afternoon like others have been successful with, so don't rush. The biggest trouble I ran into was removing the fuel injector plugs from the fuel rail. Damn red safety clips are a bitch especially when they put brackets and wiring in your way. Something soo stupid pissed me off for too long. This project took me a solid two days of just taking my time as it was 30 degrees out. Putting things back together was a lot easier. I have been the driveway family mechanic for 10 years and I do not look forward to doing this again. Do your best to find the aluminum cooler dorman 926-876 so you can avoid cracks in the future but always out of stock! Good luck Jeepers, MillerLites help a lot.

Awesome job and thank you for this videoing help me a lot to tackle this job

Clear, concise, informative, and amazing. I just wanted to replace the oil pressure sensor but I am hesitant about whether or not I should do it but your video gave me some confidence, I have turned some wrenches in my lifetime but have never done something this risky. Do you think I should try doing it myself? 😬

Excellent video! Thank you!!

great video! getting ready to do for the 3rd time on my 2014... this time using the aluminum housing, enough with the plastic!

Such a good video. Thanks for the help.

Great video, pretty confident i can pull this off. Wondering why you didnt go for a cast aluminum replacement.

Excellent Video !!! Thank you so much.

Excellent video

Great video!

I thank you very much it’s a very helpful video .

Very well done sir!

Thank you very much. video was super easy to follow. Disassembly went fine, cleanup was a breeze using a vacuum extraction tool to suction that mess up. No leaks. Unfortunately, i pinched the map sensor connector/wires when i installed the upper intake manifold (didn't see the MAP connector and it got pinched between the upper manifold and the metal bracket where the 10mm nuts attach to the manifold studs). The wires on the MAP harness look ok but i am getting P0108 (MAP) and P0113 (IAT) errors. The Intake Air Temp sensor is connected as is the MAP sensor. Not sure if i have a vacuum leak, pinched MAP wire by the connector or something else. ugh.

Great job! I felt like I was listening to Owen Wilson!😄

Just did this job ,,on a 2013 dodge challenger..3.6 L....used the all aluminum replacement part.926-876 Came with upper and lower intake manifold gaskets...83,79$ ebay.... 89.50$,,,with tax....took about an hour in the driveway... pretty easy job... Un plug coils instead of the injectors... makes it easier....

@Tyler Potter Great video!!!

Great video

Thank you awesome video

Thank you!

Our 10th Anniversary Jeep wrangler is our first ever american car. your video has helped me gain confidence in tackling this job. Unfortunately from everywhere i'm reading, the oil cooler is back ordered everywhere!

I have used the foam orange or yellow ear plugs to stop oil lines from dripping/leaking.

Well seems like I'm the only here who did way ...way more than just the intake...I forgot where all the freaking wires go. Pretty useful for that as well. I did the oil filter housing spark plugs, timing chains and guides, Radiator, obviously oil and Coolant as well as cleaning the air filter and checked the rocker arms in the valve train. Trust me this engine is a real task to work on and you'll need alot of professional grade tools. I am a Tech so I have no worries that way but the routing for the wiring harnesses is something easy to forget and not so fun to find how to put back

Thanks pal And Good Job

Thank you

You make this look doable for a diy person. How long does it take you on average to do that job? Yes i know it will take me 2 or 3 times longer but I know most shops charge a standard labor fee and i want to decide if it's worth it to do it myself if the time comes. I also would like your opinion on Dorman aluminum replacement parts. Would recommend upgrading to aluminum parts when doing this job or thermostat housing replacement jobs?

Life saving video! Saving it in case, god forbid, I have to do this again!

oh man as you were working on those intakes without putting rags in there I was just holding my breath that that socket didn't come off that auto rachet each time you were over the intake. Great video though.

My daily job is a watchmaker, that being said I am mechanically minded and try most of my jeep work myself. This was the most I have ever done in a engine bay. And would say it wasn't easy or hard, but patience is key.I just did this today and this video was what I mainly based my repair off of. I watched as many as I could and took notes. One thing I heard and I did was to open the oil fill cap. Not sure if it affects it or not but apparently it gives less oil lose. That being said, damn. It's a job. I did my spark plugs as well and tool fitment is a bitch for 2 of them. Another thing I wondered is how tall are you? You are reaching in that thing like you are a giant. Hahahha. As well as being lifted and front bumper set up with lights, it makes this job a bit harder. Everything was straight forward and in total it took me 6 hrs. Yup. 6hrs. But took my time and made sure I did the best I could do. As of now all is well. Well check for leaks, although I didn't have any, it was just a bad sensor. But from everything I heard, replace the unit if you are in there. That's it. Was some what fun. Got a little frustrated putting the lower manifold take on but it all worked out. Thank you very much for the wonderful video.

So if i were upgrading my lower intake manifold to an aluminum manifold should i clamp the fule line shut? Ive never really wirked on vehicles and your video is helping me son much! Thank you for the info!

Nice!

It goes nice and fast when the wire connector locks just slide like they should, instead of taking 10 minutes each and then crumbling into pieces when you try to lever them with a pick or small screwdriver. And then there's the PCV vent tube that is brittle from all the heat and snaps in the middle and you try to free it from the plastic support clip. Stop work and order the part, reset 2 days later. Oh, and then you find out that your injectors are crusted with burnt oil and crud, so you order those. And you find that the prior owner spliced wires directly to the inside of the coil pack because mice chewed the connector, so now you are waiting on a new coil pack and a new connector to splice in. And while you're replacing the PCV vent tube you may as well replace the PCV valve itself, so that gets ordered. And while you're waiting for parts to arrive, you decide you don't want to do this again, so you change the spark plugs. Did I miss anything ?

Thanks!

Its actually possible to tighten down the intake plenum without the thing being seated. Ive done that before. I had to take all that back apart and re-seat the intake. And if its not perfectly seated it will suck air from the side and wont run right.

Really liked the video. Very obvious you have done this quite a few times. I was wondering why you didn't torque the intakes bolts down. I know that it doesn't take a lot of torque, but you basically seemed to snug it down by feel. Do you recommend adhering strictly to the torque specs especially since this is the first time pulling these manifolds?

Hi Tyler thanks for putting this together. I think I may need to do this and have two questions. 1. Online catalogs suggest the correct oil cooler depends on engine plane date code but I can’t that info. I have a 2016 grand Cherokee 3.6 Laredo AWD. Do you know the correct part number? 2. You mention filling the coolant at the end but didn’t talk about draining it in the beginning. Is that necessary if you clamp the hose like you did?

Hey man thank you very much for this Video very well explained ,,, I like to torque everything so by chance do have the torque specs for the lower and upper manifold bolts also the 5 oil cooler bolts again thank you very much for this awesome video

Please change all intake gaskets and o-rings and you will stop problems for a long while. This is a very good engine if properly maintained. The 62te transmission is a very good transmission if also properly maintained with regular oil changes. Remember less than half the fluid is drained by removing the oil pan so needs done twice with filter replacement. My car gets 30mpg at 80mph so the engine is excellent as a last one before going electric.

I have a friend that owns a repair shop and the very first day I worked for him he asks me if I've ever done a 3.6 oil cooler. I've been a mechanic for 27 years but took 20 years off from it to work a job that would actually feed my family. I told him no I don't even know what you're talking about and he told me you can't say that after today. Needless to say it took me a bit longer to do it than it took you lol.

Pricey but worth it to get snap ons 1/4 in super swivel sockets. Made this job a walk In the park getting those 8 mm bolts

Correct me if I'm wrong, isn't disconnecting the negative battery terminal one of the first steps in the procedure? Seems I remember this always being in almost every service manual back when I was wrenching twenty...just the other day...Excellent explanation, very informative and clear with good pointers. Well done Tyler

Literally anyone with a 3.6 is having this issue I just placed a order for 5 units and I’m looking at April time frame , overall a bad design that’s been a issue since 2013 and still no recall thanks fca

2months ago i went in and did all 6coils/plugs from a one misfire. Now i get a big oil puddle and its this. So now i have to go back in again which i wish i had info about the cheap oil housing and I could’ve replaced it while i had it tore down. Story of my jeeplife.

I forgot to put the foam back in lol But will be installing new plugs ASAP so I will reinstall it then.. Not driving the car 2013 dodge challenger....3.6 L.....just got it last week....working on all the challenger issues..trunk , windows.. electric hydrolic power steering pump o ring's.....and trunk Lock..... almost done with everything...be driving in a week or so..

thanks for the video. I did it yesterday on my 2012 Wrangler and the car will not start. It cranks, but won't start over. During the installation I cleaned almost all the oil under the assembly, made sure everything lines up before tightening. Put everything together - does not start properly, cranks, makes weird noises and shuts off. Rechecked the fuel injectors - they all are connected. Any suggestions? Thank you

You can replace the cooler which is a piece of garbage and then the left bank valve train (which happened to mine) then replacing the left head because of cracked valves and not the dealer tells me that I have coolant leaking THROUGH the cylinder WALLS and contaminating the oil. He told me these are common problems. He ordered a new engine and they are on 5-6 month back order. His remedy for the wait, "drive it until it blows up" There are recalls and class action law suits for all of these problems. Stelantis has known about these problems for many years!

What are the reasons you use the impact and the ratchet? I’m looking to add to my Milwaukee collection now that I need to do this on my jeep but don’t see the difference in the tools really for this job and why you use both? Thanks for a great vid

How will the oil cooler leak manifest itself? Dealer quoted me $1.2k and am always weary when a dealership tells me I need to drop that much money for a leak. Thanks, in advance, for the insights, and great video!!!
