Question about 1999 Pontiac Grand Am GT
I believe that, u are meaning to learn why the electric cooling fans connected to the back of the radiator. Seem to turn on intermittently or not at all. Well, depending on the driving conditions, the region u live in, an the condition of the vehicle. The preventive maintenance schedule, the amount of devotion to which that schedule was followed. Is the key to most all Vehicle problems. I believe that ur pontiac has a V6-3.1liter 4sp AT. Front-wheel drive- The cooling system on ur vehicle requires it be serviced at 100,000miles Although I would'nt recommend that large of an interval between service. It is what the Manufacture determined was efficient enough. What GM did not replicate when testing that vehicle. Are those variable consequences of ACTUAL vehicle wear an tear. It is normal for the cooling fans to start up even after you turn the engine off an park. But the fans should kick in durning operation if the tempature of the engine raises above normal operating range. Which is 140F- 210F. another factor to consider. AC usage, I recommend that the cooling system be serviced,if u don't know the last time it was serviced. GM introduced a special coolant (red)necessary for that system to function properly. If the car continues to go hot the problem is electrical.
