I have now confirmed as it is defo the alternator belt as the belt is running right on the edge of one of the pulleys plus if I give it hard full lock the sqweek goes and the battery light comes on the dashboard as the belt slips.
Has anyone ever changed a alt belt tensioner and if so how hard is it to do.
A quick look at the manual and it doesn't show or tell a lot but it looks as though there are 2 maybe 3 bolts that go into the back of the block underneath thealternator. There is not a lot of room around the back of the engine from the top so it may be easier having a look from underneath to see if its better to do it from there. If possible I would try and avoid taking the alternator off as they are a real tight fit into the top bracket which is fastened to the cylinder head. Good luck
