A wet belt can cause serious engine problems when it starts to deteriorate. The damage is not always obvious until it is too late. If your car has a wet timing belt, keeping up with its replacement is important.
Cardoc provides wet belt replacement in Harrow, with same-day service available from Monday to Saturday.
Our Bosch approved garage has Bosch and IMI-accredited technicians who carry out repairs using genuine parts and manufacturer specifications, without affecting your vehicle’s warranty.
A wet belt performs the same essential timing function as a conventional cambelt, but it runs inside the engine oil. Over time, exposure to heat and oil can cause the rubber material to break down.
The problem goes beyond the belt itself. Small fragments can contaminate the engine oil and block the oil pump pickup, restricting the flow of oil around the engine. If this happens, important components may not receive the lubrication they need, potentially resulting in costly engine damage.
There is no single replacement interval for every vehicle. The recommended mileage and age depend on the engine and manufacturer, so checking your service history is a sensible place to start.

Brought my car in after lights appearing on the dash. After it being checked over, Paul informed me of exactly what was wrong and how to fix it. He was really informative and honest. I cannot fault the work done on my vehicle and the customer service received. I will definitely be returning!
