Thermostat Gates or MISHIMOTO

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 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.

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.

I’ve got the gates 180, 5 years strong no issues

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?

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

I put the mishimoto 160* in hot water to test it out. Lo and behold, wax started seeping out.

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.

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.
