Dont know if anybody knows the reply to this .but i will never know.. Fitted a new fanbelt and how do i ajust it, i have done it once with the engine running and the noise went away, if i fit a new tensioner dos anybody think the noise will go. if i spray oil over it it gos very quite down there.so i am thinking it the tensioner.also i think if i do the ajuster up any more i think the belt will snap.(it only makes a noise first thing and when the car has cooled down)
