Radiator Fan

[ekstroemtj]

Dear Members

I would like to ask some details about the cooling system, in detail the radiator fans.

I was checking the Search but couldnt find what i was looking for.

I will replace the fans, minimum the big one which is on passenger side.

Car was checked with tester at Porsche. Guy told me the big one is not working. My impression is, no one is working.

Please can somebody tell me at what levels the fans are going to start. When the small one, when the big one. When both?

Thank you bery much

I read the booklet. Thank you again for pointing me to

This . Very interesting and helpful to understand these cars.

I read the section about the radiator fans. As i understand, they are always running TOGETHER. Difference is just the speed.

So regarding my fans. There is more than one problem.

The smaller fan always comes on when you turn on the air conditioner.

Try this first.

Rien . Nada. Nothing. Complete silence.

According to my porsche shop only the big one

Is bad

Check fuses F1, F2, F10 in the motor compartment fuse box.
