i took my car to the pontiac dealership, they said everything was ok.
they told me they dont know whats wrong with it, i either think its the thermostat even though they say its not.
but about 2 yrs ago i wrecked it into a ditch and my dad is telling me when i did that, theyre was a piece that took air to the radiator from under the car like a "air duct" "air dam"
or something like that he said we ripped it off and im wondering if thats the problem, ive done alot of research and couldent find any kind of air duct or air dam for the car, if you could please tell me what that part is that recieves air from under the car to the radiator to cool down the car i would really appreciate it, like i said i have no idea what it is called.
ty, gary
Is the fan coming on with the AC? The air duct or dam shouldn't matter with the car not moving
fan comes on when ac is on yea, but it still over heats, idk whats up with it at all
Failing water pump maybe?

Overheating can be caused by several issues. Could be just one, could be several working together to make you life a rolling hell.
Cooing fan not operating
Thermostat stuck closed or partially open
Radiator clogged inside
Radiator fins clogged with dirt, leaves, grass, bugs, etc.
Water pump will not or cannot circulate coolant
Air pocket in cooling system
Ignition timing off
head is cracked or gasket is shot and combustion gases are being forced into the system.
Crack in a cylinder wall to the water jacket.
If the car is running great, you haven't lost any coolant then I'd start with a new thermostat. Easy, cheap, fast. From there I'd do a water pump and next a radiator removal and either replacement or have it rodded out by a radiator shop.
You can have the system pressure tested to see if coolant leaks into a cylinder or if a cylinder leaks into the coolant system also but this is beyond the tool inventory of most home based mechanics. These pressure tests are best performed on a stone cold engine.
Good Luck
