Hi,

Please can someone help????? My 2006 RRS Supercharged is over heating in traffic. Had water pump changed, but the fan does not seem to run up to full speed every time when I am in a german traffic jam (frequent occurrence)!!!!

I have heard the water pump wiring could be incorrect, or the fan sensor or viscous fan could be faulty.

Does anyone have any experience or solutions for this problem please????

If I need a new fan, any recommendations would be appreciated as there are so many available....

Thank in advance for your help.

The one you are talking about is the auxiliary pump for the supercharger which can come from the factory wired backwards which usually brings on limp mode when you are driving hard not in traffic so unlikely thats your issue

Ok. thanx Geoff, limits it to sensor or fan!

heck your fan is working it should sound noisy when you start the car and then quiet and when iy starts to get hot you should hear it if it come on but it does sound like the viscous is maybe not working correctly if it only does it in traffic

Thanx Geoff,

it runs, but does not speed up each time it is hot. Have ordered a new complete fan.

Some say if you can hold the fan when it’s supposed to be on when temp is high it means the viscous is knackered but never had the bottle to try to be honest

and if it chops your fingers off its working ok

And that’s why I never did it

and 350 quid for a new fan is cheaper than prosthetic fingers!
