A properly functioning timing belt is critical for the operation of an internal combustion engine. If the belt were to slip or break, it could lead to catastrophic engine failure. In interference engines, where the transmission allows for overlapping movements between the pistons and valves, a timing belt failure can result in the pistons striking the valves. This can cause significant damage and lead to costly repairs, making regular maintenance of the timing belt vital.
