Hi there My MK2 16v was squealing from the fan belt area (on and off but especially when cold or idling) so when it was in for its service last month I had the fan belt changed as well. To my relief it solved the problem but 3 weeks later its back but slightly different; It no squeals loudly when I first start the car up from cold for around 5 seconds before disappearing for the rest of the journey. If I then re-start the car from hot its fine but next morning it does the 5 minute loud squeal again which I'm sure the neighbours love Any ideas what this may be as keen to get it gone?! Cheers guys
Yup... what he said ^^ Belt pulleys can also get polished smooth over time, to the point where belts are more likely to slip. A bit of medium-rough emery paper on the pulley surface can help to give it a bit more grip, and use brake cleaner to make sure there's no oil on there.
Thanks so much for the quick reply guys - thankfully a very small job it seems! Thats this weekends job sorted
Make sure you loctite the bolts holding hte alternator to the block! These have a habit of loosening themselves off on my race car! I resorted to stud lock in the end, no problems since. Might just be the solid front mount vibrations though!
Never had that problem on a road car, so you're probably right that it's due to the non-standard mounts.
