Thermostat OEM Audi or MOPAR

I highly suggest only getting genuine mopar. Myself and others have had issues with the generic part store thermostats that were fixed by using mopar.

I replaced mine with this one and it has been running perfectly for 6+ months after my original one stuck open. I would not buy anything other than Mopar.

I had the same issue and throwing a bad thermostat error code. I had the thermostat replaced and it kept happening. He said the thermostats out there are crap and they’ve had to change some 3 times. He did recommend getting a Mopar thermostat if I could. It was replaced and I’ve had no issues.

The OE version is the only one that works. Knock off t-stats will generally last a few weeks to a few months. The OE thermostat has been updated, pops at 203 degrees and lasts much longer than anything else. An OE thermostat seems to fail open. Whereas the knock-offs fail shut.

Gave up and bought the genuine Mopar stat, haven't had issues since.

Finally got around to replacing the thermostat on my 2000 XJ. Temp rarely hit 210 unless I was idling for a while so I suspected a bad thermostat. Sure enough it was stuck in the open position. I was able to find an OEM one part # 5202 8186AC. 195 degree with a weephole. Noticeable difference in performance and it’s nice to have heat again.

Yep, these are a known bitch to bleed out the air, as well as aftermarket thermostat's not working well after replacement. I have seen some go thru a few to get one that works.

Oil cooler and radiator. I changed the thermostat when my radiator went. I would recommend using a mopar thermostat as I had two aftermarket fail on me

I had a very similar issue. Radiator and Thermostat replaced after accident. 2014 WK2 3.6 V6 was overheating when I drove up the mountains in Colorado. The problem was the mechanic put a Napa thermostat in, then replaced with another napa thermostat. I bought a MOPAR thermostat and swapped it myself.

The current plastic thermostat looks a little more beefy, but is still shatty plastic. They're commonly failing at 30-55k miles in the stuck closed position, instant overheat.
