Question about 2002 Pontiac Montana
Are you talking about your coolant thermostat? if so follow the upper radiator hose down to where it connect to the engine, remove the bolts on the peice the radiator hose is clamped to, remove old thermostat and clean gasket surfaces. Put on new gasket and new thermostat and replace bolts. then top the coolant back off, I failed to mention at the start you should drain the radiator of about a gallon of coolaqnt before you start so it won't go everywhere when you take the bolts out. Merry Christmas!
