Is the time belt replacement criteria exaggerated?

처리 내용

If the engine you are putting the timing belt on is an interference engine, it is definitely NOT exaggerated. The reasoning here is, the timing belt is cheap insurance over breaking the old one, which can cause complete engine destruction (at the worst). You cannot just look at the timing belt and see if it's bad/good. You can possibly look at the print on the back of the belt. If the print is really clear , it may be okay. Really, the only way you could tell is if the belt starts fraying, but usually by then it's too late. I changed out a belt once (on a non-interference engine) where just the teeth on the belt at the crankshaft gear had peeled off. The crank would just sit and spin when you cranked it over and the cam belt stayed still. The belt itself looked okay, until I took it off the engine. Then you could see where the particular teeth on the belt were missing. Point is, you never know how much life there is left in a timing belt until you change it, then you can start counting
