Cam Belts

What is a cambelt?

The cambelt, also known as the timing belt, is one of the most crucial bits of kit in the engine.

It’s basically a rubber belt with teeth on it which synchronises the rotation of the crankshaft and the camshaft.

What does it do?

In a nutshell, it regulates the way your engine works.

It controls the opening and closing of the valves to the cylinders in time to ensure correct combustion in the engine. Its primary role is to control the timing and sequence of the opening and closing.

Like most bits of kit, it will eventually wear out. If it cracks, tears or snaps, it can cause a whole heap of expensive engine damage. With older cars this usually means they won’t be worth repairing.

How often should you change it?

There’s no ‘one size fits all’ rule when it comes to how frequently a cambelt should be changed, as a lot depends on the car.

Most manufacturers suggest either a time- or mileage-based change, depending on which comes first.

There’s a lot of variation between both manufacturers and engines when it comes to when a change is due. This could range from 40,000 miles up to 100,000 miles, and from four years up to six years.

Your vehicle handbook will specify when a cambelt change is due.

Manufacturer’s intervals should be treated as the absolute maximum, as failure of the cambelt can cause serious mechanical damage.

Any early-warning signs?

Often there’s no sign the cambelt’s reached the end of the road as it’s so deeply embedded in the engine.
