A cambelt, or timing belt, is a reinforced rubber belt that connects the crankshaft to the camshaft, ensuring the engine’s valves open and close at the correct time. This precise synchronisation supports smooth performance, fuel efficiency, and power. Because it operates continuously while the engine is running, the cambelt is a key wear-and-tear component. Modern materials make it durable and flexible, but it’s essential to follow recommended replacement intervals. Failure to replace a worn cambelt can lead to serious engine damage, including damage to valves, pistons, and cylinders.
The economy and power of your engine will be affected over time. If failure of the cambelt were to occur it could result in significant damage to the engine, and a very high cost.
What if I'm unsure whether my cambelt has been replaced or not?
Your vehicle service book should have a record of any instances where the cambelt has been replaced.

Your cambelt—also known as the timing belt—is one of the most critical components of your engine. It keeps the internal parts of your engine moving in perfect sync. Over time, it wears down, and if it snaps, it can cause serious and costly engine damage.
That’s why regular cambelt servicing and timely replacement are essential for keeping your vehicle safe, reliable, and performing at its best.
Cambelt intervals vary depending on the make and model of your vehicle, but most manufacturers recommend replacement every:
If you’re unsure when your cambelt was last changed, it’s always safer to get it checked—waiting too long can lead to unexpected and expensive repairs.
Unfortunately, it's not possible to carry out a quick visual inspection of cambelt condition. To gain access to the belt, parts of the engine have to be dismantled. During a cambelt change we strip down the relevant components of the engine and renew the belt and cambelt tensioner. Then we re-assemble the engine and road-test your vehicle before recording it in your service book.
A cambelt (timing belt) replacement typically costs between £500 and £1,000, with an average, common price point around £500–£600 for many cars. Costs are heavily influenced by the make and model of the car and any additional work carried out during cambelt replacement.

Failure to replace a cambelt can lead to it snapping, which can cause severe, often terminal, engine damage.
