Review on Dorman 902 2836 Integrated Thermostat Assembly by Blake Larson

This thermostat was easy to fit and proved to be of high quality. It has held steady at 203 for the last three months, but for the past week it has started to climb above 210 shortly after launch and then dropped back to 203. Today it reached 215 and then fell back to 203 after the start. a few minutes. This is worrying because she usually never hesitates. I'm going to replace it with a failsafe thermostat (which only sticks in the open position) because I think the sticking is likely to get worse and I can't risk it never opening.
