Mahle is the OE replacement for the thermostat, the Chrysler logo is on the part but sanded down. Autozone sells them with PT# TI23695 I just replaced mine last weekend.
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.
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’ve been using Germany-made Mahle thermostat for years. Now it throws a code that the heater doesn’t work (so it won’t open electrically, but mechanically it is working just fine), but no leaks.
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.
In regards to replacing the thermostat, Id stay away from Mahle/Behr. I just ran through two that stuck open, so far the Borg and Warner from FCP can actually hold temp @ -19C, which the Mahles could not at -10C.
I have the same one in my E53 X5 3.0 and it takes forever in the winter to warm up. I replaced the old one as it was leaking but the new one takes like 10miles to get fully up to temp. If I have a long coast up to a stop the temp gauge will actually go back down.
