Ford Escort Diesel 1997 - Belt squeal in the morning / cold engine - Englishbullterrier

Hi all, just had the alternator removed/refitted (with a new belt) after I refurbed/fixed it. (I don't currently have the ability to get underneath it).

This car has a/c so the compressor was also dropped (but not disconnected) to get to the alternator.

Now, in the morning, it's developed quite a loud belt squeal. This disappears if I rev the engine (blip it really) for a short while.

Can someone advise if this normally indicates a loose or too tight belt ?

Many thanks all..........ebt

It often indicates a loose or worn belt but the problem may be caused by a tight bearing either in the alternator or something else contacting the belt. Try putting some WD40 on the belt and see if that clears the problem, if it does it's the belt slipped rather than a bearing, if the WD40 doesn't help then it's likely to be a mechanical issue elsewhere.
