Thermostat MISHIMOTO or MotoRad

All I could get on short notice was a motorad...been in there over a year now and haven't had an issue. It's an OE 195 temp and seems to open around 205-210.

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 found an exact copy of the factory thermostat with the baby one next to the primary the Amazon description says it’s good up to a 2000. It’s a Motorad. My temp never moves from the set point.

Mishimoto has a great thermostat plus it has a lifetime warranty

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?

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.

I had issues with the MotoRad that every parts store in Canada seems to sell

issue that i noticed is that the jiggle pin is inside the bridge, compared to the standard one. i have installed the thermostat, bled the coolant, and still made sure that the jiggle pin and head gasket carve out lines up at the 12oclock position when installing; but now theres some ticking noise sometimes and i can feel my heater blowing really hot air (warmer than the usual heat).

Motorad isn't a good brand. You don't want to do the job again in a year.

Installed a Motorad thermostat and noticed the temp gauge dropping on the highway. I never had this issue before I changed the tstat
