Thermostat Wahler or MISHIMOTO

A proper Wahler thermostat is what solved it.

I just put a new Waller in every 8 to 10 years when it comes time to redo the cooling system. Never had a leaking or stuck thermostat but we do live in Southern California, so I think things tend to last longer Here

I've had a Wahler fitted for 1.5yrs and everything's ok so far

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!!!!

I wanted to upgrade from plastic and got an aluminum Mishimoto thermostat, but i didn’t notice that it opens at 180°. Can i get away with the 180° thermostat, or should i ship it back and re-order a different, higher rated thermostat?

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.

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.

The wahler thermostat is either broken or its too cold where i live cause the car never really gets up to temp (or my temp sensor is broken).

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