Question about 1999 Pontiac Grand Am GT
I have a 2001 grand am GT. Its the V6 ram air. It started to overheat all the way to redline and also i noticed that the ac would only throw cold air and not any hot air (with the heater on). I replaced the water pump about 3 months ago but im not sure if the mechanic put it incorrectly. Now they think i need to rebuild my engine. Is that the solution or is it something more or less complicated? I have a DHP Pcm and a throttle body as my performance parts.
If you get cold air when the heater is on, you have lost quite a bit of coolant. Now the question is what caused you to lose your coolant.
As long as you didn't drive around with your engine overheating, your engine should be fine. I think you would know if you had damaged your engine.
When the engine cools, fill your cooling system, start it up and check for leaks or overflow. If the only water your see is from the overflow when the engine starts to overheat, then it very well could be the water pump or thermostat. Chances are the thermostat will need to be replaced anyway.
If this doesn't solve your problem, write back.
