Automotive Knowledge 101: What is a Timing Belt?

If you're wondering what a timing belt is, then we can be of assistance at Diablo Subaru of Walnut Creek in Walnut Creek, CA. A timing belt is an important part of your engine that keeps the camshaft and crankshaft running correctly. A timing belt will need to eventually be replaced because it will wear over time and could snap.

If your timing belt happens to snap while you are driving, then your vehicle will suddenly stop. This can put you in danger if you're driving at higher speeds or in traffic. Moreover, if you have an interface engine, then a snapped timing belt could cause the pistons to break and intake valves to bend, which would cost thousands of dollars to repair. If your vehicle has a non-interface engine, then you don't have to worry about damage to the pistons or intake valves. However, you should still have a damaged timing belt on a non-interface engine replaced immediately.

How many miles can you drive before your timing belt needs to be changed? For most vehicles, every 60,000 to 100,000 miles is when a timing belt needs to be replaced. Check your owner's manual to see the specific recommendations from your vehicle's manufacturer.
