Mine has been chilling little to no problem so far in 20-30° PA

Sometimes going down long hills engine braking will close the thermostat and will warm up to 200, but then opens back up

I replaced it with the motorad thermostat that opens 10° lower

Pros: little to no problem

Motorad (SNN-2000-195) 195 thermostat for quite awhile now. Zero issues.\n\nI did try something that claimed to be a Mopar t-stat my last upgrade and it wouldnt open up until about 225 degrees. It was like 40 bucks too. So i went back to the Motorad (SNN-2000-195)

Pros: zero issues

Cons: Mopar opened at 225

Part number: SNN-2000-195

Update: replacing the MotoRad thermostat it had in it with an OEM one fixed it and it sits at 1/3rd like it should.

Pros: fixed the temperature issue

In the past and up to several months ago, I’ve always gone with Saleri (Italy) pumps and Wahler (Germany) thermostats for the M54 and have had great results.

Pros: great results

I would suggest a failsafe thermostat from Motorad and an OEM Motorcraft seal.

Pros: failsafe thermostat

Rating 1.0

I bought a Motorad 7908203 Thermostat and replaced it. Got all the air out of the system after replacing and all seemed good but now, my car only heats up to the correct temp when idle and when I start to drive is when my car starts to cool down closer to C again and doesn’t heat up any further.

Cons: car cools down while driving

Vehicle: Chrysler 200

Part number: 7908203

Don't get the Motorad that includes the thermostat housing, because that one is junk, and the thermostat housing is not OEM sized.

Cons: junk quality, non-OEM size
