Remove the Stat and see what happens to your overheating problem

Do you hear the cooling fan? When engine is idling?

Its your choice-Remember the computer has to read the temperature from the coolant temperature sensor for other purposes such as fuel delivery and tranny shifting/overdrive etc. Best bet is just get another T-Stat with the correct Temperature for your model.

The final decision is yours-Good Luck

Should be on the heater hose before it goes in the heatercore.
