Thermostat Gates or OEM Nissan

I always use Premium Thermostats, which are billed to fail open. Gates or Stant are my favorite brands.

i personally run a 90c/195f one, the GATES 33209. it gets cold here in WI and it will hold 192f on the highway with the heat at speed 1

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

I have an 06. Had the same issue. Bought a cheap thermostat which turned out to be no good but acted the same as the old thermostat. Then, I changed EVERYTHING else in the coolant system, lol. Switched to Gates, problem solved.

OEM Nissan, but slightly more conservative with cooling.

Replacing the Thermostat with a OEM part has solved the issue (with coolant flush) from a dealership.

To complement this, the Gates thermostat I bought for a Mercedes M272 engine was identical to the Mercedes A2722000115, except that the Mercedes logo cast into the housing had been (mostly) ground down.

After reinstalling an OEM thermostat, I am very happy to say my high temp issues have been solved!

We had to replace thermostat from Nissan group Infinity. So far no problem right now

we warrantied a Gates thermostat on a pentastar 3.6L three fkn times because the guy said it kept overheating going up hills. Originally replaced for P0128 thermostat code. Then we put an oem part in and it’s never overheated since.
