I’ve had so many replacements fail in all my Nissans over the years that I just get an oem one from a dealer. Never had an oem one shit out yet.
Pros: OEM reliable, no failures
Vehicle:
Nissan
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
Mishimoto has a great thermostat plus it has a lifetime warranty
Pros: great thermostat, lifetime warranty
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
I recently changed my thermostat due to my temp gauge occasionally dancing. The old thermostat appears to be bypassed as theres no actual thermostat in the housing. After putting on a new nissan one and oem gasket i bled the system with a overflow funnel for about 40 minutes until i stopped seeing bubble. Also using peak 50/50. Afterwards my overheating problem has gotten worse i overheat in about 10 minutes. I tried bleeding again and same results.
Cons: overheating problem worse
Vehicle:
Nissan
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
please remove the mishimoto thermostat they fail a lot, it happened to me as well.
Cons: frequent failures
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
