Squeeking/ shreiking drive belt

[Nutrunner]

My drive belt makes a terrible noise for about 2 mins or until engine starts to warm, i have tried various belt dressings and the only way to stop it is a quick spray of silicon oil. Its 3 weeks, replaced the belt because the old one looked knackered. Is something else worn. The idler pulley and water pump replacement made no odds, its definately the belt. 4.0 chim 1995

Mine was the same, to cut a long story short the new belt came off again tiny stone in the grooves, cleaned up the pulleys and your aunts husband is Bob.
Wouldn't advise silicon lube 'cos your belt will just slip quietly and probably not charge the battery too well, talcum powder on the other hand will quieten it down until you get the job done. Funny looks from passers by though but a luverly whiff from the engine bay when warm

I friend of mine was told by a mechanic to drip candle wax onto the belt. He tried it an it worked a treat. Lasted for ages as well.

My 1998 Chimp has the same symptoms. It shreiks within 2 or 3 minutes from cold and stops shortly after. Interestingly it stops when I am on the throttle but starts when I come off it.

My garage tell me that it is the inlet manifold ( taking to much air) but they have been unable to fix the problem, even after three visits!

Has anybody got a solution?

I had this problem, fixed it by tightening my manifold bolts which are notorious for loosening off on 500's

I had the Inlet Manifold taking in too much air problem, only manifested itself when the engine was warm though. The dealer just tightened it up apparently and it was fine. Caused a non starting problem as well though, not sure how, but thats what they said.

Bizzare noise, sounded like an old whistle kettle just under boil constantly.

Slightly off topic, but this has reminded me of an early fault I encountered with my 500. The belt snapped the first week I had the car from new, and the AA guy who replaced it found the pulleys were out of line.

I had ticking noise from Chm 450 fan belt, three dealers told me it was stones / changed it over a 2 yr period , but kept coming back.
Finally it was sorted think they had to also make some pulley adjustments, but noise gone !
