Hi Guys,
My son's 1994 Corrado 2.0 16v has an intermittent problem with the cooling fan. It sometimes seems to be rubbing against something, although I can't quite see what so far. This doesn't happen all the time it's operating - just now and again. Son also tells me that on one or two occasions there has been a noise that sounds like the fan motor is straining to get the fan itself to turn, suggesting that the blades are catching on something to the point where it won't spin, although this is purely a guess as I haven't been able to replicate this.
Apart from removing the top cover (above the radiator area) and having a good look round, does anyone have any ideas for a cure? Is this a common problem on this VW engine? I've tried a squirt of WD40 around the spindle area in case it was dry but no improvement as yet.
All help appreciated.
Thanks

i'd suggest taking the fan off, and having a look at the electric motor assembly. The brushes may be worn, and the commutator is probably mucky. Take the cover off the motor and get some meths, a bodkin and an old toothbrush. Scrape out the grooves between on the commutator, and check that the brushes are long enough. I doubt the fan motor has been touched in the 12 years it's been on the car.
I cured a heater blower fan in a Tipo that was blowing slowly, and blowing fuses on the top setting by doing the above.

Thanks Mr Yokel - I'll give it a go!

While it's off,look at the housing and the blades to see if it has been catching on anything.

Thanks for that. Will do.
