What are the usual signs of a bad timing belt? My car is making loud squeals and other weird noises, I've looked at all my belts, and none are cracked or broken, I tried tightening the tensioner and still nothing, so I've come to the conclusion that my timing belt is going out. It's been doing this for a few days, and I'm worried that it might go on me before I get the money to replace it.
How much does a usual timing belt job take?
