Cooling fans

Postby zorak » Wed Oct 23, 2013 1:16 pm

Hi all
I pulled my aircon a while ago but still have both fans on the radiator.
Which fan is the aircon fan - drivers side or passenger side?
Also what is the easiest way to trip the engine cooling fan to come on? It doesnt seem to come on even after a long drive.

Cheers

Drivers side is AC fan.

What car do you have?

Drivers side is AC, but confirm by letting engine warm up and look at which fan is spinning.

The later NB8 models do take a while to come on... it will, it may take 10 mins of fast running (2000rpm) when sitting still. I would not want to trip it as you're not doing a good test of the system - you want to see it come on after running idle/fast for 10 mins as you then know it is working ok.

As above, if the car is moving it's not likely to set the fan off.


Is there a reason to remove the a/c fan? I would have thought it's nice to leave there for some extra cooling if it's ever a really warm day. The A/c switch will become a manual fan switch.

Thanks guys - i like the idea of keeping the ac fan and switching it on/off with the ac button but it doesnt work for some reason anymore so will just pull it out.
