i took top timing belt cover off today, belt is in perfect condition but it is pretty close to the edge. should i be worried? me drive belt pulleys squeak though. i thought it was the idler pulley, but when i sprayed belt dressing on pulleys the squeal went away when i hit the tensioner. So do I just need to replace the tensioner? Is there a way to tell if the idler pulley is bad? and any specific way to replace the idler pulley? (haynes manual has nothing about it) thanks in advance.
