Thermostat MOPAR or OEM Mazda

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 narrowed it down to a bad thermostat and bad radiator. I ordered the OEM Mazda parts for $450.00

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.

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.

Batteries crap and so is the thermostat / heat and the trim on the steering wheel and gear shifter is thin and cheap and will come off everything else. Car is great

I just got this fixed at the dealer on my 21. Its the thermostat. They put in over a million bad ones and don't want to own it with a recall so they sent out a TSB. There's also an extended warranty for all the cars for this part/labor.

I replace thermostat even the whole block. Same issue. This fucking car don’t heat.
