There's not a standard change interval for cambelts.
- Depending on the model and the manufacturer, the recommended interval can be anywhere between 30,000 miles and 100,000 miles. There will often be a time-based interval specified too e.g. 60,000 miles or five years, whichever is the sooner.
- Sometimes the manufacturer will revise the recommended interval during the life of the vehicle so it's best to check with a franchise dealer as they will have the most up-to-date information. They will need to know the make, model, engine number and model year.
- In most cases cambelt failure results in serious damage to many other components in the engine - a major rebuild or even replacement engine will be required!
It does no harm to renew the belt early. If you buy a used car it's wise to get the belt renewed if you are in any doubt that it has been renewed at the appropriate time.
