Question about 2003 Pontiac Grand Am
Youve replaced the thermustat in your car
your car may be air locked
remove the cap for the coolent bottle and let the car run for a bit you should get bubbling and a boiling sound comming from the bottle
worning: hot liquid dont stand too close while the bubling is going on wate till it stops then shut off the car
(keep a close eye on the temp gadge while the car is running after the air has bubbled out if thecoolent is low replace with the rite coolent
with any pontiac/chev vehicle its usually "DEX-COOL" its usually orange in color (dont put in the green stuff youll ruen your moter) if it calls for the other coolent (the green stuff) put that in and not the orange stuff
i hope this helps you i hope you get your car fixed

check the coolant level fiirst...if that is low it wont give you any heat.....to change the thermostat you have to follow the top radiator hose to the engine.at the send of it you will see a clamp take it loose...then you will see the thermostat housing its held in place by 2 bolts . once you remove them you have the thermostat....make sure you clean all the old gasket material off both the housing and mount.also make sure you get a new gasket.
