Thermostat MOPAR or MISHIMOTO

The Mopar stats (mfg by Motorad) can be had from Rockauto, and are generally well regarded, if more expensive than generic parts store units.

I got a Mopar thermostat from the dealer a few months ago. Works much better than the previous two aftermarket units

In case anyone else comes across this post, it was the aftermarket thermostat. I managed to get a hold of a mopar one yesterday and the gasket around it was just slightly larger than the aftermarket one and needed a little bit of resistance to seat it. Now my truck is getting up to temperature quickly and working great.

I replaced the thermostat in my wifes 2014 journey with the V6. It was an easy and straight forward job.

I just bought one off RockAuto. I have to overhaul my entire coolant system and through some searching on this subreddit I saw a lot of people saying the Motorad brand kept failing after a few months. I didn\u2019t want to risk it so I opted for the Mopar thermostat from RockAuto for $35.

I spent a good chunk of change on the Mishimoto thermostat and it got stuck closed within a couple months. Needed the car back right away and all I could get was a dirt cheap MotorRad one. Darn thing has been it in now without issue for a good long while now.

Stick with Mopar thermostat. I went off brand and it didn\u2019t work correctly.

The thermostat failed twice. Once at like 80k miles and again at 115k miles. The second time it failed I replaced it with an aftermarket one that had a metal stem instead of plastic. It made it until we traded it in.

Get that mishimoto garbage out of there and put a new oem thermostat in there. Unless you really lile pulling the engine out, to replace coolant seals and rusted rotors...

please remove the mishimoto thermostat they fail a lot, it happened to me as well.
