I installed a Gates one a couple months back and it worked well for a little while; engine got up to operating temp fairly quickly and stayed there, but now it’s running really cold no matter how long or how hard I drive it. Think it’s stuck open.
Pros: quick operating temp
Cons: running cold, stuck open
I installed a Gates 33009S 195 degree after my Hughes install and haven’t had issues.
Pros: no issues
Vehicle:
Dodge RAM
Part number: 33009S
The brand new thermostat wasn’t opening all the way. One new Gates thermostat fixed the issue.
Pros: fixed issue
Vehicle:
Jeep Grand Cherokee
I always use Premium Thermostats, which are billed to fail open. Gates or Stant are my favorite brands.
Pros: fail open
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
Pros: holds temperature well
Vehicle:
Volkswagen Golf
Part number: 33209
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.
Pros: solved overheating issue
Vehicle:
Dodge RAM
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.
Pros: identical to Mercedes part
Cons: logo mostly ground down
Vehicle:
Mercedes
Part number: A2722000115
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.
Cons: kept overheating
I’ve got the gates 180, 5 years strong no issues
Pros: 5 years strong, no issues
