What to do if your Pontiac cooling fan is not running?
There is a table located here that shows diagnostic steps you can take. It’s for a 1999 model, but 1999-2001 are virtually the same (I own a 2001 G/T model). Hook your temp sender up to a meter and drop it in some boiling water.
How does the cooling system work on a Pontiac?
The PCM sends the signal to the BCM, which turns the fans on. Or you can buy a separate temperature fan relay system with a temp probe and bypass the system. It will work as normal cooling when needed only. Its the connecter that you unplug from the temp sensor.
Why is my Pontiac Grand Am GT not cooling?
It leaks coolant into the cylinders and causes inefficiency in the cooling system, leading to low coolant and overheating. You can replace this gasket with a metal one, the repair is a little involved but I managed with a Haynes manual. Good luck! My 2000 Pontiac Grand Am GT (6 cy/3.4L) has been having cooling issues.
Why are the cooling fans on my car not running?
The problem persists; the engine will reach 200, the thermostat opens (determined by watching the temp. gauge), but the fans do not start. If I disconnect the (new!) temperature sensor, both fans start.
