engine cooling fan comes on after air con regas
« on: May 23, 2012, 08:30:19 am »
Hi,

I've had an air con re-gas which is working fine but ever since I've notice my engine cooling fan kicks in all the time when the engine is idling this happen even when the car has been started from cold. if i turn my air con off the fan doesn't kick in. is this supposed to happen or is this a fault?

Hi
Both of my 6's have done exactly the same thing, I am sure it is quite normal.

this is quite normal in fact if it didnt id get worried heat build up in engine bay is the natural enemy to engine performance youll notice two fans in your car one for the air con and one for the engine so what your hearing is your air con fan try turning all heaters or air con off then see what happens.......

Yep if i turn off the air con i get no fan

I thought it would be something to do with cooling the engine cos of the extra heat load from the air con. what confused me was the fan kicking in straight away before the engine got hot.

thanks for the reply ;-)

The fan kicking in isn't to cool the engine, it is to draw air through the AC condensor to take the heat out of the AC gas.
