I put a thread in the garage section the other day about my fan belt squealing but I've had time to look at it today and it's not the fan belt. Today I tried to tighten the fan belt but the squealing persisted so I then loosened it again and took the fan belt off to check it was ok, I then moved the car a few feet backwards without the fan belt on and the queal was still there, I've narrowed it down to one of the wheels that the fan belt goes round and of the three it's the one that is nearest the bulk head and it's below the timing belt I think. Anyone any ideas what is causing this noise and if I'm doing any damage by driving round, any help is appreciated. Thanks.? 
Well the one nearest the bulkhead will be the crankshaft pulley (Alternator, top front and water pump, bottom front). You say its squealing even with the belt off! That is odd - and possibly very worrying - Stop driving it, seriously!
I don't think it is that pulley. My money is on your timing belt tensioner which is just above that pulley, obviously under the timing belt cover. Stop driving (I can't emphasize that enough) and check it out mate because if it is that (and I'm almost certain it is) it can break up and cause pistons to meet valves - ask Gaz, he knows all about that with his 20V
It is recommended that the tensioner is replaced when you replace the timing belt, too many engines have been written off because of the damn tensioner breaking up and not the timing belt itself
Give me a call tomorrow (after 11am, I'm on nights tonight) if you want to chat about it..........
