engine cooling
 

Hi All,
I have Audi A6 2.7T (2002). I saw three fans next to the radiator but only one works when engine is running, temp. after regular driving (there wasn't smoke frome tires on every intersection) is 230F. Is somebody able to explain how it works, when the others are ON. Thank You for an answer

They come on a different temps. One will be dependent on the A/C. Try driving it really hard! You can get them all on if you try!
