997.2 cooling fan running for extended period.
Discussion
The engine fan came on for the first time ever today, and it wasn't that hot, nor was I in particularly heavy traffic. Then it stayed on permanently until I turned off and restarted the car. Is this normal?
I've just had the car back from the OPC after some work, but nothing to do with the engine fan as far as I am aware.
I check everything!13m said:
Turns out its the fan under the NSF front panel. It seems to be coming on even from cold, but will go off if I turn off the ignition and re start the car.
Porsche wants to book it in again....
I had the same problem in a 997.2 GTS. Ended up swapping the control unit for the fans under warranty.Porsche wants to book it in again....

As part of the work they did earlier in the week they had to remove the front spoiler. I cannot help thinking the two may be linked.
It was one of the fans jammed with debris apparently. OPC Nottingham was kind enough to sort it gratis, but now the problem has started again.
Is anyone familiar with the anatomy of the cooling fans? Is a blockage something that can be cured with the judicious use of a pressure washer, or otherwise easily remedied by a physical intervention? I have to assume that it isn't very difficult to address the problem.
Morning!
Yes - I have had this on my 997.1 C2s. Using a pressure washer, it's possible to clear the fans from behind by blasting through the slats in the wheel arch liners.
Occasionally however, it's prudent to drop the wheel off, and remove the five bolts to clear behind the cowling properly. The grit deposits eventually form a sludge which builds up to the point where it's almost like a weak concrete mix jamming the fan, and there's really nowhere for it to go.

Thanks. Its not a problem I had in the first year but year 2 and it has happened twice. The second time it sorted itself out.Yes - I have had this on my 997.1 C2s. Using a pressure washer, it's possible to clear the fans from behind by blasting through the slats in the wheel arch liners.
