The OE version is the only one that works. Knock off t-stats will generally last a few weeks to a few months. The OE thermostat has been updated, pops at 203 degrees and lasts much longer than anything else. An OE thermostat seems to fail open. Whereas the knock-offs fail shut.
I got a duralast part from autozone with a lifetime warranty for 25 bucks. My jeep has been been running well for the last year since the change to the duralast part
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?
Duralast thermostat? They are a piece of shit!
