Thermostat Gates or Motorcraft

I requested they use only Motorcraft thermostat, because I knew there was a part # update. Threw the updated Motorcraft one in and it solved the issue.

Soon as i bought Motorcraft all was normal again

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.

Make sure you use the motorcraft thermostat.

Go with the Motorcraft thermostat as it has a rubber seal on the outside edge.

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’ve had a Motorcraft thermostat fail after 100mi on my Ford

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.
