Does anyone have info on how to replace the thermostat on a 1994 Cutlass Supreme, 3.1 V6? The thermostat is buried in the middle of the engine and it looks like there is not way to put a socket on the housing. What parts do I have to remove? Pep Boys wants $130 labor to replace the thermostat!

 

Drain about 1 gallon of coolant from radiator Follow upper radiator hose to engine housing Remove 2 bolts on housing--make note how thermostat is installed Clean both surfaces completely Install new gasket and thermostat Tighten both bolts evenly and securely Re-fill radiator slowly to prevent "airlock" Check for leaks Start engine with heater on Run to normal operating temp Check coolant level
