When should my fan be cutting in ?
« on: 03 August 2009, 09:57 »
Dont think i have heard fan running in the 3 months that the Golf  has been on the road , Temp gauge never goes above half way but in traffic or round town temp light comes on and flashes constantly . A bit of a hot rubbery smell come into car and to be honest worries me a bit , Any ideas people  :sad: Thanks

should come on at around 3/4 on gauge, see the coolant faq on tips on testing all the different parts of the cooling system

Check your PAS and alt. belts. I had that smell and my alternator belt kept flipping out of the V and upside down  :angry:  I didn't bother fixing it because it failed the MOT not long after  :lipsrsealed:

But for the purest engine experience, displacement has no replacement. All other methods are simply attempts to artificially recreate the benefits of displacement.

Sorry to jump in here btw, but my fan also comes on quite often, especially if i've been darting around town - although temp gauge never gets to half way... is my gauge bust or is that normal? I have a 16V and I understand they run hot.  :undecided:

It can't do any harm can it?  :huh:
My 1.6's fan used to come on quiet a lot last year summer time, I knew this because the fan was buggered and made a racket and sounded like the engine was failing :grin:  :shocked:

the gauge could be under-reading, what does the oil temp say? could be the fan switch is cutting in a bit early too. or you may have the after-run system fitted and the wire has fallen off and is earthing to the engine. its a single pin sensor with a black wire, on the inlet somewhere
