This is a known issue affecting thousands of 2012+ JKs, most notably in extreme cold conditions.

Now back to the original thread:
I have a 2014 JKUR. I noticed a big puddle of engine oil in the garage last weekend, and looking under the Jeep, the oil was dripping off the clutch cover, so I suspected it was the rear main seal. After thinking about it, I thought it was odd that the clutch wasn't chattering like I expected it would with a rear main issue, so I was a little skeptical that it was actually that. I just received a call from the dealer, and they said it was a cracked oil cooler housing.
Googling around, there are a bunch of people who have experienced this already, and all seem to be 2014s, including at least one Cherokee KL (the new one) with the 3.2. So, I looked around and yes, the 3.2L uses the same oil filter/cooler assembly as the 3.6L.
The 2014 3.6L oil filter/housing/cooler appear to be NEW parts from 2013 and earlier. They probably re-engineered these so they would be common between the 3.2L and 3.6L, saving money.
So, ladies and gentlemen, we have a Fiat/Jeep/Chrysler clusterfork in motion.
This is not a trivial issue. While mine cracked and wasn't leaking a ton, others apparently have blown out. If this happens on a trail 20 miles from town, you are going to be screwed.
We need a survey sticky thread on this issue. How do we do that?:atomic:
This is a known issue affecting thousands of 2012+ JKs, most notably in extreme cold conditions.
Failures range from:
- Cracked housings
- Leaking O rings
- Sensor failure
Important notes:
- 2012 & 2013 are the original style
- 2014, 2015 & 2016 have an updated style including a filter change
- 2017 & 2018 had a change in the Oil Pressure Sending Unit and will be a different part number
- Dorman makes an aluminum alternative (926-876)
