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!!!!

Pros: coolant stable, low temperature

Vehicle: Volvo XC70

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.

Pros: working without issue

Cons: stuck closed quickly

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...

Cons: poor quality, causes damage

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.

Cons: s'ouvre à mauvaise température, déçu de la réponse, frais de douanes

Vehicle: Nissan
