vs
Thermostat MISHIMOTO or OEM Nissan
Reviews
Since going with the OEM thermostat, my temp gauge has stayed pinned just below the middle of the gauge, even towing campers and heavy loads on hot days.
Pros: stable temperature, handles heavy loads
Vehicle:
Nissan
Only an OEM Thermostat fixed it.
Pros: fixed issue
Vehicle:
Nissan
I had this exact issue with 3 aftermarket thermostats that were opening too early. Bought one from Nissan and my temps went back to normal
Pros: temps went back to normal
OEM Nissan, but slightly more conservative with cooling.
Pros: conservative cooling
Vehicle:
Nissan
Replacing the Thermostat with a OEM part has solved the issue (with coolant flush) from a dealership.
Pros: solved issue
Vehicle:
Nissan
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?
Pros: aluminum, upgrade from plastic
Cons: wrong opening temperature
Vehicle:
Jeep Wrangler
Forget about the Mishimoto thermostat. The OEM thermostat is way more reliable and does the job.
Cons: less reliable than OEM
Vehicle:
Mazda
I put the mishimoto 160* in hot water to test it out. Lo and behold, wax started seeping out.
Cons: wax seeping out, failed test
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.
Cons: failed quickly, left stranded, coolant puking
Mileage: 3218 km
when installing a mishimoto thermostat, check that the shoulder/flange is the same thickness as oem. Otherwise your stock hardware WILL NOT FIT. You will bottom out the bolt in the timing cover and snap that mf. Those bolts are extremely hard to access and a MAJOR HEADACHE to get extracted.
Cons: incorrect flange thickness, hardware fitment issues, difficult extraction
