    Radiator (?) cycling on and off....

    My 997 (with 5,000 km on the odometer) has lately had a fan cycle on and off. It's coming from the right front of the car and I'm not sure what fan it's for. It usually occurs when the a/c is on, but it will go on and off when the a/c is off. There are no warning lights on the car and it otherwise runs well.

    Is this a common occurrence? I would say the fan cycles on and off when driving in city traffic once or twice every few minutes. Thanks in advance!

    Re: Radiator (?) cycling on and off....

    normally could be okey but the best to anwer is your service dealer, check it ASAP. The fan misbevaviour can cause the engine to overheat, or stay cool which is pretty much the same. Not good at all/.

    Thanks Dilinger,
    Just spoke to my service advisor and have an appointment to bring the car in. He has seen this happen in 996's before. He thinks that the left side fan is not working, and the right side is working double time to keep up.

    Re: Radiator (?) cycling on and off....

    that mght be the case as if one radiator is not eorking the temp sensor gives signal to the other radiator to keep working to lower the temp...

    Better to go to the service and return with no problem , than to go later with a BIG problem

    Re: Radiator (?) cycling on and off....

    Just an update on my radiator "problem"

    The dealer had my car today and noticed that a rock had wedged itself into the drivers-side radiator fan, preventing it from working. They removed the rock and now all is well.

    So many posts pertain to problems with the car itself, just thought I'd share a problem I had that was not related to build quality issues.

    Re: Radiator (?) cycling on and off....

    i'm glad to hear that it's not a build quality problem! pleased to hear your car is ok too!
