#1: Slow Sppeed fan Author: ldare2000, Location: SwanseaPosted: Tue Nov 22, 2011 11:02 am ---- Hi,
I posted on here that my CC was overheating.
Did a compression test and one cyclendar was much lower than rest.
Paid 374 to main dealer to head gasket change which was by far cheapest quote.
Then had car back.... Still overheated.... Just collected today got stung 141 quid for resistor and labour as slow speed fan wasnt working.
Should slow speed fan always be on? Looks like it kicks in around 92'c is that right?
Thanks
Louis

Car gets brought in over heating & with head gasket gone, doesnt take a genius to work out somethings wrong with the cooling system.
Slow speed fan comes on around 92 deg C
The slow speed fan will also run if the air con / climate control system is switched on.

Hi,
You're spot on thats exactly how I felt which is why I felt I should double check all their work after the 2nd visit. Glad 92c is the point as that's what is happening so should all be good now.
Thanks

If you slow speed fan fails your high speed fan will kick in at around 100c however if like me your high speed fan comes on whilst stuck in rush hour traffic you may find all the high speed fan will do is get you home to face a big repair bill.
Cheers
Louis

If the resistor has failed then normally the fan will be at high speed even if the ECU thinks it's at low speed
