Cambelt - Car-Tech


At Car Tech we specialise in replacing cambelts in Leighton buzzard and surrounding villages.

We stock a wide selection of correct manufacturer approve timing tools that are required to fit the belt correctly and professionally.

A cambelt, also known as a timing belt, is a vital component in the internal combustion engine of most modern vehicles.

Here’s a breakdown of its function and importance:

What it does

The cambelt synchronizes the rotation of the crankshaft, which spins due to combustion in the cylinders, with the camshaft. The camshaft controls the opening and closing of the engine’s valves, allowing air and fuel to enter and exhaust gases to leave.

This precise timing ensures the engine operates efficiently and generates optimal power. Without a properly functioning cambelt, the valves and pistons could collide, causing significant engine damage.

What it’s made of

Typically made of reinforced rubber with strong teeth that mesh with gears on the crankshaft and camshaft.

Some high-performance engines might use metal timing chains instead of belts, due to their durability at higher speeds and temperatures.

Why it’s important

Prevents engine damage: Failure of the cambelt, due to wear and tear or breaking, can lead to catastrophic engine damage as pistons and valves collide.

Maintains engine performance: Proper timing ensures optimal fuel efficiency, power output, and reduced emissions.


Cambelts have a recommended replacement interval specified by the car manufacturer, typically between 60,000 and 100,000 miles or every 5 to 10 years, whichever comes first.

Ignoring replacement recommendations can lead to expensive engine repairs.

It’s crucial to follow the manufacturer’s recommended schedule and have the cambelt replaced by a qualified mechanic.

Usually, you can find the recommended replacement in the service or owners manuals. If you would like help, then please feel free to contact us as we have access to the manufacturers data base that has every make and model.

How to spot a faulty timing belt

Identifying a faulty timing belt can be tricky as it’s an internal engine component. However, there are some signs and symptoms that can help you spot a faulty timing belt:

  • Ticking noises: If you hear ticking or clicking sounds from the engine, your timing belt could be damaged.
  • Engine problems: A fault with your timing belt can cause a problem with your engine’s timing, potentially leading to poor performance or a rough-sounding engine.
  • Hard stalling: Stalling can be caused by timing belt issues, as the balance between the camshaft and crankshaft is disrupted.
  • Loss of power: A timing belt slipping or broken can lead to a significant loss of power, as your engine may not work correctly.
  • Visible damage: Sometimes, you may be able to spot visible signs of timing belt damage, such as cracks, fraying, or missing teeth.
Why is the cambelt so important?

It prevents engine damage by ensuring valves open and close at the right time, preventing them from colliding with pistons.

How long does it take to replace a cambelt?

The time it takes to replace a cambelt, also known as a timing belt, can vary depending on several factors, but generally, it takes between 2 and 8 hours. Here's a breakdown of what affects the duration:

Can I replace the cambelt myself?

It's a complex job requiring specialised knowledge and tools. It's best to let a qualified mechanic handle it to ensure proper installation and avoid potential risks.

What is the difference between a cambelt and a timing chain?

Both achieve the same purpose, but cambelts are rubber with teeth, while timing chains are metal. Belts are more common and require regular replacement, while chains typically last the life of the engine.

What does a cambelt replacement cost?

Yes, but it requires knowledge and tools.
