Does My Car Have a Timing Belt?

If your car is 20 years old or more, you probably have a timing belt. Manufacturers started to phase out the timing belt in favor of a metal timing chain in the 1990's. Unlike the belt, timing chains can last for your car's lifetime. Timing belts, on the other hand, need to be replaced at certain intervals to keep your car working.

If you're not sure if your car has a timing belt or not, you can check your owner's manual or look up the maintenance schedule online. If you don't see a timing belt on your list of routine repairs, you don't have one. If you do, it's important to stick to the recommended schedule to prevent bigger issues. But timing belts can snap ahead of schedule, so having it checked during routine inspections is a good idea.
