Review on 🔧 Dorman Engine Coolant Thermostat Housing Assembly - 902-3312 (Select Models) - Improved SEO by Robert Aliraqi

Fits my 2004 WJ 4.7 no problem no leaks. Pay special attention to the cutout in the housing, which is designed to align with the pressure relief. The gasket and housing are keyed to align properly, but I had to rotate the keyed gasket on the thermostat myself to get it aligned. When the previous owner installed the one I replaced, the 180 degree alignment was incomplete and the pressure relief valve was closed and they cut a key from the gasket to fit it. Given some bad reviews about the thermostat itself, I'll be keeping a close eye on it. If it doesn't work after 2 years I will update the review. 8/24/2020***UPDATE*** 8/12/2021 - Still opens and closes as intended at 195f. Zero problems, zero worries.
