Many engines use a toothed rubber belt to synchronize the movement of the camshaft and crankshaft. The belt may also drive the water pump and the balance shaft (if equipped).
When the time belt breaks the engine stops instantly and will not restart. On many vehicles pistons and valves will collide, leading to very expensive repairs.
On most timing belt replacements we also replace the oil seals located behind the time belt. These seals tend to leak and if oil gets onto the new belt it will break prematurely. Belt tensioners and idler pulleys are checked. If any are found to be worn, they will be replaced to ensure full timing belt life. The water pump is also checked.
Recommended Frequency: Every 96,000 km or 60 months (Some cars require service sooner and others later. Check manufacturers’ recommendation)
