Anybody else having issues with there Grand AM over heating? I've got a 99 Grand AM SE , & it's over heating. I cannot drive it more then 5 minutes without it starting to over heat. I'm getting no where fast with this vehicle.

2.4 or 3.4?
Have you checked the coolant level when the engine is cold? If the level is low, you have a coolant leak, and you are creating an air pocket.....
For 2.4, the place to look is the weep hole of the w/p...
For the 3.4, you want to check for leaking at the lower intake gaskets and the w/p....
Other possibilities are, the radiator, heater hoses, radiator hoses, heater core(you would smell that in the interior of the car), etc.

Yes kaySVT, we've all had some over-heating in our Grand AMs. Some more than others. LOL
But as what Tech II mentioned, coolant level, leaks, possible thermostat stuck closed too.
Hope we helped!
