Questions and Answers

Saturn SL2 Cooling Fan Problem?

Q. Vincent, First, thank you for doing such a wonderful job on About.com. I love reading your part of the site. I have a question. I drive a:

  • 1996 Saturn SL2
  • 1.9 liter DOHC
  • Manual transmission
  • About 79,000 miles
  • Fuel Injection
  • ABS Brakes
Saturn SL2 Cooling Fan Problem?

A while back I had to have my thermostat replaced. It seems as far as I can remember that ever since I had this done, my cooling fan will shut off when I turn my car off. I thought I had remembered that my cooling fan would stay on for a few minutes even after I turned my car off – is that not correct?

My situation is that I am currently out of the United States and will be for a while. Where I am, there are no Saturn dealers, and I am hoping that this is a problem that I could fix myself?

My cooling fan does work when I am driving, air conditioner OFF, and as long as the car is actually turned on. Only as soon as I turn off the car, BAM! the fan shuts off also. Alternatively if I do use the air conditioner, the fan will also come on.Can you help me?

Sincerely,
Eric

A. Here is how the cooling fan operates. When the PCM supplies a ground to the coil of the Cooling Fan Motor Relay, current is allowed to flow through the switch contacts of the relay to the engine cooling fan.

The engine cooling fan will be turned on or off by the PCM dependent upon engine coolant temperature, vehicle speed or A/C on request. Under high ambient conditions, the fan may run up to four minutes with the key off. If the PCM should become disabled a ground for the fan control relay will be automatically provided.
