227. 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.
When should a timing belt be replaced?
The replacement interval depends on the vehicle and engine. Drivers should follow the manufacturer's specified mileage and age interval rather than waiting for obvious symptoms of wear.
What happens if a timing belt breaks?
The engine will stop operating and, depending on the engine design, the pistons and valves can collide and cause severe internal engine damage.
