Thermostat MOPAR or MISHIMOTO

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.

It’s now got an 85°c Mishimoto thermostat. Took it out today and got it up to temp and did multiple 0-85mph pulls. The new thermostat opens at 85°C/185°F. Under load the coolant never registered above 197°F!!!!

Mishimoto has a great thermostat plus it has a lifetime warranty

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

Même souci sur 350Z

Le thermostat Mishimoto s'ouvre à 82° au lieu de 68°/ la réponse du constructeur → du moment ou la température reste stable !!!!!!!!!

Je suis énormément déçu de cette réponse surtout au prix et frais de douanes que cela comporte.

Forget about the Mishimoto thermostat. The OEM thermostat is way more reliable and does the job.

I put the mishimoto 160* in hot water to test it out. Lo and behold, wax started seeping out.

I had 2 fail back to back. The first lasted 3 months, a couple thousand miles, the 2nd lasted 5 weeks, also a couple thousand miles. Left me stranded. 275 degree spike followed by coolant puking.
