Just replaced my thermostat and temp sensor on the top of the housing yesterday, not too difficult. I took the advise of many here and used some lube on the O rings, went in pretty easy. Previously the coolant temp was 73 tops on the highway and the temp needle was always parked on the left dot. Now the temp stays at 79, and the temp needle is just a hair left of dead center, very pleased.
