The cambelt, or timing belt, keeps your engine's valves and pistons moving in time. On many engines, if the belt breaks the pistons hit the valves, causing major engine damage. It gives no warning, which is why manufacturers set a replacement interval by kilometres or years.
Engines with timing chains don't have a fixed replacement interval, but chains and their tensioners can wear, especially if oil changes have been stretched.
Cambelt replacement
We replace the cambelt according to your manufacturer's schedule. A proper job usually includes:
- A new cambelt and tensioner
- Idler pulleys where specified
- The water pump, where it is driven by the cambelt and the manufacturer recommends it
- Auxiliary belts checked and replaced if worn
Timing chain problems
- A rattle on cold start that fades as the engine warms
- A check engine light with timing-related codes
- Rough running
- Usually caused or worsened by low or old oil, so regular servicing helps
Not sure when yours is due?
If you've bought a used car with no record of a cambelt change, treat it as due. Tell us the make, model, engine and mileage and we'll check the interval and quote. Get a quote or call the workshop on 011 783 3440.
Common questions
How do I know if my car has a belt or chain?
Give us the make, model and engine and we'll tell you.
How often should a cambelt be replaced?
At your manufacturer's interval, by kilometres or years, whichever comes first.
Should the water pump be replaced too?
On many engines it is driven by the cambelt and recommended at the same time. It saves paying for the labour twice.
Is a rattling timing chain urgent?
Yes. Have it checked soon before it causes damage.
