How does a timing belt work?

A timing belt provides a connection between the camshaft and the crankshaft to ensure that pistons and valves work together in proper sequence. Timing belts require more frequent replacement than chains, and have been replaced with timing chains on many vehicle engines manufactured today.

What happens if the timing belt breaks?

If a timing belt breaks on a free-running type of engine, the engine will stop, and the vehicle will not run. If the timing belt breaks on an interference type of engine, there will be engine damage. Other timing belt problems include slipping of a loose belt or a damaged belt from wear and tear, which could cause poor performance of the engine.

What are my options?

The vehicle can be taken to a local dealer or repair shop, or the owner can replace the belt. There are numerous automotive websites that offer repair services or sell belts and replacement parts. Other sites offer free DIY instructions or service manuals can also be purchased.
