Where is the thermostat located on a 2000 Grand Prix SE with a 3100 motor
Follow the top radiator hose back to the engine. Should be right there. The housing is secured with 2 bolts. Do NOT work on it while the engine is hot!! Squeeze that hose first to make sure the cooling system isn't under pressure!! Otherwise scalding hot coolant will BLOW out VIOLENTLY & you'll be injured!! Always work on a cooling system that has been sitting at least 1 hour. Then remember to squeeze that hose! HTH. -Jim
This engine has a special coolant fill proceedure. there are 1 or more air bleed ports that need to be opened to bleed the air trapped in the system.
