ive started hearing a strange hissing noise and last noise it finally got much worseand was coming from the cam belt, but i just rang this guy up to order a timing belt kit and he said it would be the alternator belt ttry tightening that first, where would i find this other belt and how do i tighten it ??

 

down the same side alternator will have a 13mm bolt with a slide bracket undo the bolt and lever the alternator to tighten the belt abit! all the above is IF the belt is loose!
