Cambelt Replacement Norwich

The cambelt, or timing belt, keeps the engine's valves and pistons moving in step. It is a rubber belt, it wears silently, and when it snaps on most engines the pistons meet the valves and the engine is scrap. Manufacturers set an interval in miles and years, whichever comes first, and the years matter as much as the miles because rubber ages whether you drive or not. If you have bought a used car and there is no receipt for the belt, assume it has not been done. We check the interval for your engine, replace the belt with everything that runs with it, and give you the receipt that keeps the next owner happy.

When Is It Due?

Every engine has its own figure, set by the manufacturer, and the range is wide. Some are due at 40,000 miles or four years, others at over 100,000 miles or ten years. The figure is in the service schedule, not the general handbook, and it is the years limit that catches out low-mileage cars: a 12-year-old car with 50,000 miles is well past the age limit on almost any engine. Give us the registration and the mileage and we will look up the interval and tell you honestly whether it is due now, soon or not for years.

Why It Is Never Just the Belt

The belt runs over a tensioner and one or more idler pulleys, and on many engines it also drives the water pump. Those bearings wear at the same rate as the belt, and a seized idler or a leaking pump destroys a new belt just as surely as an old one would have snapped. The labour to reach them is the same labour, so the correct job is the full kit: belt, tensioner, idlers and, where the belt drives it, the water pump with fresh coolant. Doing the belt alone to save money is a false economy we will talk you out of, and we will say so on the quote rather than in the workshop afterwards. Some engines also have an auxiliary belt that comes off to reach the cambelt; it is replaced at the same time.

Timing Chains

Many modern engines use a chain instead of a belt. A chain is meant to last the engine's life but does not always: stretched chains, worn guides and failing tensioners cause a rattle on start-up, a check engine light for camshaft timing, and eventually the same catastrophic failure as a snapped belt. Some engines are well known for it. We diagnose chain wear with a timing check and the fault codes, and replace chains, guides and tensioners where needed. Tell us the engine and we will tell you whether yours is one to watch.

Good to know

How often should a cambelt be changed? It depends on the engine: manufacturers set an interval in both miles and years, whichever comes first, ranging from around 40,000 to over 100,000 miles and four to ten years. Give us the registration and mileage and we will tell you the interval for your car.

Wet Belts

A number of recent small engines run the timing belt inside the engine, in oil. These "wet belts" can degrade early, shedding rubber into the oil pick-up and starving the engine, and their replacement intervals have been shortened by manufacturers after problems in service. If you have one, using the exact specified oil and not stretching the interval matters more than on any other engine. We know which engines are affected and will check the interval that applies to yours.

What We Do

Interval check by registration and mileage, a written quote for the full kit for your engine, the job done with the timing locked and verified with the correct tools, fresh coolant where the water pump is changed, and a dated receipt with the mileage for the service history.
