2013 oil filter/cooler housing leaking

I just encountered a common oil leak coming from the oil filter/cooler housing. We purchased our Wrangler Unlimited brand new and for the most part has been a reliable vehicle. The repair shop that is fixing this issue says they have seen many 2012 forward 3.6 Wranglers with this issue. I'm posting this so that if it happens to you, and I'm also writing to Fiat/Chrysler in the event that they happened to address this design flaw.

Its a pretty common problem for most all 2014s and less common for the rest of the 3.6s. The filter/cooler part (2012-13 is 92957NB I think) Is over $200 and a ton of service hours.

If you have any mechanical know-how, you can save yourself some money and do it yourself. get some valve intake manifold gaskets, and spark plugs while youre at it, because you need to remove the intake manifold to get to them anyways.

Drain the coolant and oil before you start... ill only make that mistake once.

I actually have a fair amount of mechanical acumen, on older simpler motors, but newer motors intimidate me, because a mistake could really cost you big bucks.

The company I used to do the repair, they used the OEM par and it was over $400. and it was 4 hours of labor. My total bill was $1000 with a 10% military discount.

My hope is that Fiat/Chrysler is paying attention to this really flawed design and fixes this major problem.

And one person recently attempted a self repair and destroyed the engine due to losing a bit in the intake. If you attempt this get yourself a fiberoptic camera for your phone and double check the plenum before reassembling.

I just did this repair in my 2012. Also replaced my rockers and lifters in my right cylinder head due to tapping/ticking. Engine is running like its new again. The worst part was cleaning all the crap in the valley and on the intake manifold taking special care not to get any of that crap in the manifold where the valves are. Disassembly was ok and reassembly was even easier. Taking off the pcv valve on the rear of the valve cover was a pain

Well, the JK is not a simple vehicle in any way. You want a high output, clean burning small CI engine you have to put lots of "stuff" on it. It all works great till it doesn't. You think the JL is any better,,LOLOLOL. When these Wranglers get old and start to fail they will not be re-buildable like the old ones were. When it won't pass smog and the CEL lights up you own a parts vehicle. I am guessing a 20 year life for most. I know there are some 80's and 90's jeeps out there but that was then and this is now. Enjoy the JK but don't put a ring on it.

I checked with my local Jeep dealer and they want $600 for the job. They do a lot of them so to them it's like an oil change. I'll let them do it and perhaps get a warranty on the work done. I have done a lot of mechanical work on vehicles to the point of engine rebuild but I am just over it. With any luck I'll never need the work done.

Between that and all the other things that can go wrong it might be as much as $3500. That's not even close to the sales tax on a new one.

Back in 2016, my 2013 JKU developed an internal crack in the oil cooler and it let oil flow into the cooling system. It was quite a mess. Luckily it was still under warranty so the dealer fixed it at no charge to me. They said that if I were to pay for it myself, it would have been around $1,500. They had to flush the cooling system and replace the oil cooler and several cooling hoses.

Just paid 460.00 to have the oil pressure sensor changed in my 2012 JKR... They also did the spark plugs since they had to pull the manifold anyway. I had them check the oil cooler when they did it just in case.

I normally do my own stuff but doing it on a 4" lifted Jeep on 35's in the driveway in the middle of winter in MI was not the way I wanted to go, so I bit the bullet and had the shop down the street do it for a couple hundred less than the dealer wanted......Really need a taller garage door...LOL

I have a friend who just replaced his himself since he was out of warranty. Jeep agreed to pay for the oil cooler itself as he purchased it from a dealer. Maybe worth looking into to at least get them to pay for the parts. And yes, he did get paid. Took 30 days but he got a check.

its a real bear to replace....need to take the whole top of the engine intake manifold off to get to it....very poor design....I helped a friend do the repair and it takes a full 8 hour day to accomplish. an $800 repair bill is very fair if you cant do the work yourself. if you are patient and take your time, it can be done in your garage. mark everything and take photos.
