Pontiac Grand Prix- Close to Heating-up

Thermostat most likely. Relatively cheap. Letting the engine run hot can be very expensive.

a few possibilities

cost of doing nothing is probably about 800 dollars fixing it will cost probably less than 200.

and there's a fan relay involved too. There is not a temp sender for the fan. There's a sender for the PCM. When the PCM sees hot enough temps, it grounds the relay thus energizing the fan.

With 2007 days away, it's time to flush the coolant > a few possibilities

Okay, this is an update. On 12/19/06 --I took my car to a mechanic. He said the Intake Manafold Gasket was leaking --$648.00 was the cost. So he proceeds with the repair and i drive my car less than 1 mile home. Today 12/20/06 -I get in my car to go to work and the car is dead; not even the power locks, power windows ---nothing at all operational. Mechanic comes to my house and says ---your battery is dead -"did you leave something on?". NO. I really need advise on what to do. Anybody have any ideas?

Charge and load test the battery. It's likely shot. The battery in my 2002 GM vehicle died over a year ago.

Sounds like the serpentine belt wasn't reinstalled correctly. It drives the alternator(charges battery) and water pump.

Check to see if the battery cables are loose. The mechanic may have forgotten to tighten them back up when he was done.
