Hi,
Can anybody tell me how to ttighten a Vauxhall Corsa 1.2 diesel fan belt? The Alternator seems to be fixed hard to the engine - with no adjustment groove at all!

There is a roller tensioner on it - you will need a Torx key or spanner on the tensioner pulley centre bolt and turn it against the spring tension - Hold the tensioner in position by inserting a suitable locking bolt through the special hole provided.
If the belt is loose then the tensioner has taken up alll the slack it can and the belt must be replaced and Vauxhall recommends that you change the tensioner roller at the same time.
