Cambelts & Timing Chains - Cars & Light Vans – Norwich & Norfolk
Cambelts and timing chains are critical engine components that keep everything inside the engine moving in the correct order and at the correct time. Their job is to synchronise the movement of the engine’s internal parts so the engine runs smoothly and efficiently.
A cambelt (also known as a timing belt) is a reinforced rubber belt, while a timing chain is a metal chain. Both perform the same role, but they wear in different ways and have different maintenance requirements depending on the vehicle.
If a cambelt or timing chain fails or slips, the engine can stop running instantly and may suffer internal damage. For this reason, these components are replaced or inspected based on time, mileage, and manufacturer guidance — not just when symptoms appear.
At BURE AUTO CENTRE, we carry out cambelt and timing chain work for cars and light vans across Norwich and Norfolk, explaining clearly what your vehicle uses, when it needs attention, and why.

Understanding cambelts vs timing chains (plain English)
Cambelts
Cambelts are made from reinforced rubber and operate inside the engine. Over time, they degrade due to heat, age, and use.
Most cambelts are replaced at set intervals, commonly between 5–10 years or specific mileage limits, depending on the vehicle. Some engines also use a wet belt, which runs inside engine oil and has its own service requirements.
Timing chains
Timing chains are made of metal and are generally designed to last longer than cambelts. However, they are not maintenance-free.
Chains rely on proper oil quality and pressure. Poor servicing or low oil levels can cause chains to stretch or tensioners to wear, leading to noise, poor running, or timing issues.
When should you consider cambelt or timing chain work?
You should consider cambelt or timing chain attention if:
- Your vehicle has reached a mileage or age interval recommended by the manufacturer
- There is no clear record of the cambelt being replaced
- You’ve recently bought a used vehicle
- The engine is making unusual rattling or ticking noises
- Warning lights related to engine timing appear
- The vehicle runs poorly or struggles to start
- A service or inspection highlights timing-related concerns
Cambelts often show no warning signs before failure, which is why replacement is based on schedule rather than symptoms.
Benefits of addressing timing components on schedule
Looking after cambelts and timing chains properly helps to:
- Protect the engine from internal damage
- Maintain smooth, efficient engine performance
- Avoid unexpected breakdowns
- Support long-term vehicle reliability
- Preserve engine value, especially on higher-mileage vehicles
- Give peace of mind that critical components are in good order
Timing system maintenance is preventative — it’s about avoiding problems rather than reacting to them.
If you’re unsure whether your vehicle uses a cambelt or timing chain, or when it’s due for attention, we’re happy to advise. We’ll check the specifications, review the service history, and explain the options clearly before any work is carried out.
