Cambelt Replacement

Why?

The cambelt does a very important job – it drives major parts of the engine and keeps everything working in harmony. Quite simply, it is one of the hardest working parts in your engine. It is essentially a belt made out of a rubber compound and requires replacing in order to prevent crack, tears, or snapping. Keeping this belt in good condition essentially minimises the risk of major engine damage such as pistons and valves colliding etc. If it were to break it could cause serious damage to your engine resulting in a hefty bill or, in worst case scenarios; even requiring a new engine.

When?

It is recommend that your cambelt should be changed every 60,000 miles or every 4 years (whichever comes first), if your car was registered before September 2009, and every 5 years or 80,000 miles (whichever comes sooner) should your car have been registered after September 2009. This applies to most models – but please call us to double check this as there are some variations to this rule.

We always recommend replacing the water pump at the same time as cambelt replacement, if the water pump is driven by the cambelt (please see below for an explanation).

Why do you always recommend a water pump change at the same time?

Your vehicles water pump is driven by the cambelt. Three common water pump failures include:

  • Bearing can fail & seize
  • Water pump can leak
  • The impeller on the water pump can break off – causing the engine to overheat

If the water pump were to seize, the cambelt would stop suddenly and break. If the water pump leaks or the impeller breaks – the cambelt will need to be removed – in effect having to pay the same labour cost again, in order to replace the water pump. As it is located in the same place as the cambelt it gives you confidence and makes financial sense to replace them both at the same time – saving labour costs in the long run.

The latest generation VAG group vehicle water pumps have an electric solenoid, these water pumps require a special bleeding procedure and distilled water must be used. We have all the specialist equipment and knowledge to carry out this repair correctly.
