SOURCE: 2003 Pontiac Grand Prix SE 6 Cyl - Cooling Fan Not Operating

the fan motor could just be bad, you can test this by removing the fan and connecting a wire to each terminal and to a battery. the wires hooked up one way will spin the fan and the other way will spin the fan backwards so you cant hook it up wrong. I hope that helps you out!

Low coolant and service engine soon lights are on. Is this a sensor problem I had to replace the thermostat as it stuck closed and the engine overheated.


Your coolant could indeed be low. Double check the level. Often when the cooling system appears to be full, it drops when the thermostat opens and the coolant flows into the engine.

When turn on air it only directs the air flow to your feet and turn switch to other positions it does nothing as per to direct air in those positions.


Sounds like you have lost vacuum in the engine bay,a broken vacuum hose? Most air flow control is done with vacuum operated dampers

I have a 1995 Pontiac Grand Prix GTP 3.4L DOHC....... The engine is over heating (yes it has coolant in it).... and I had noticed a leak in the coolant so we replaced the radiator (which had a hole in it)...


Maybe a backflushing of the cooling system can help to make it cool more efficiently.

Sediment can build up in the cooling system causing a lack of flow of coolant.

Also, the thermostat could be stuck closed, as others have suggested.

I have a 1995 grand prix I had the water pump replaced but its still leaking coolant and runs hot how do I fix it?


you nave to determine where the problem is. This could be caused by many things here is a list that I can give you but can't be sure as I don't know what was all done when the pump was replaced. Some mechanics don't do the same things when they repair or replace water pumps. Here is possible causes, Plugged catalytic converter Could cause overheating. This could of caused the pump to fail as it would of caused the engine block to get hot and boil the coolant out from the block. As well when the mechanic changed the pump he should of done the following if he inspected the following.

1. Rod out radiator and use scaler for engine before putting in antifreeze.

2. Replace water hoses that may have separated and collapsed

3. Replace Radiator cap Because if the cap has a weak spring allowing coolant to flow into overflow tank and thus, after several cooling and heating periods over a few days causes you to lose coolant.

4. A loose water pump belt. Or a spring tensioner worn out.

5. If it has a automatic Transmission could have plugged oil cooler which could cause the engine to overheat.

6. Oil cooler plugged can cause this as well.

7. A/C Malfunctioning causing the condenser or evaporator to heat up water.

8. Plugged condenser with foreign material it it not allowing correct air flow.

9. on some models fan clutch worn out.

And the list could go on this is not a full list of what could cause it but gives you an ideal how far ranging the problem could be. Hope this helps thanks for using fix-ya.
