Your timing belt makes sure the different parts of your engine move in sync, and if it starts to fail, you’ll want to replace it as soon as possible. But what will that cost? Will your warranty help?

No matter whether you’re changing a belt for maintenance issues or a timing chain for running issues, you need to be careful.
