173. Timing belt
A timing belt is a toothed belt in an internal-combustion engine that synchronises the rotation of the crankshaft and camshaft so that the engine's valves open and close at the correct time relative to piston movement.
The timing belt is a wear component and must be replaced according to the vehicle manufacturer's maintenance schedule. If it becomes excessively worn or breaks, the engine can stop suddenly and, in many engine designs, serious internal engine damage can occur.

What does a timing belt do?
The timing belt synchronises the crankshaft and camshaft so that the pistons and valves move in the correct sequence while the engine is operating.

What happens if a timing belt breaks?
Loss of timing-belt drive disrupts the engine’s timing and can stop the engine or cause serious damage. The consequences depend on the engine and failure. Follow the manufacturer’s replacement and inspection requirements rather than assuming all designs fail in the same way.
