Video tutorial

The timing belt is one of the most important components of the engine, and its failure can cause serious damage to the engine itself, potentially requiring replacement. The lifespan of the timing belt varies from model to model and is specified in the vehicle's user and maintenance manual.

Generally, for a petrol engine, the lifespan is around 62 miles or 5 to 6 years, while for a diesel engine, it can be as much as 112 miles or 10 years. However, the degradation of a belt can vary due to many factors, such as driving style and weather conditions, so it is recommended to check it at least every 18,000 miles.
