Timing Belt Replacement in Vantaa

When the timing belt needs replacing

The timing belt links the crankshaft and camshaft rotations and makes sure the valves open at exactly the right moment relative to the piston travel. If the belt snaps or jumps a tooth, the valves strike the pistons and the internal engine components are destroyed — the bill can run to thousands of euros or force a full engine replacement. Manufacturers specify the replacement interval in the service schedule: most common is every 5–10 years or 90 000–150 000 km, whichever comes first. A car racking up city kilometres quickly hits the mileage limit, but a lightly used car is limited by age — rubber hardens and cracks as it ages. The belt kit includes the belt itself plus the tensioner and idler pulleys. All are replaced together because they wear at the same rate and stripping the engine later is the same amount of labour. On most engines we also recommend replacing the water pump at the same time, since it sits under the timing belt and replacing it separately later is not cost-effective.
