The cambelt is a vital component of the engine, as it synchronises the movement of the camshafts and crankshaft, ensuring that the valves open and close at the correct times.
Over time, the cambelt can stretch or wear, which can lead to engine damage if it fails. The manufacturer recommends that the cambelt is changed every 10 years or 100,000 miles, whichever comes first.
It is important to have the cambelt changed by a qualified mechanic, as the process is complex and requires specialist tools.
