Well i have tryed every thing i can think of .to stop this rattle but it is still there has anybody got any idea what it could be. it is coming from the main belt where the alternator is and the lolly pop tensionor which has been replaced,and it is not the bottom pulley as some had rubber ones, not any bearings, i have tryed spraying it with brake fluid which did stop it for about 4 days .. so i think it could be some thing to do with the belt. any body had the same proplem?
