The timing belt is a reinforced rubber band that connects the crankshaft, which drives the pistons, to the camshaft, which controls the opening and closing of the engine’s valves. The precise connection ensures that the valves open and close at the right times in relation to the position of the pistons. This timing is critical because if the valves collide with the pistons, serious engine damage can occur, known as a catastrophic failure. Therefore, the quality and condition of the timing belt cannot be overstated.

The primary purpose of the timing belt is to ensure that the engine's valves open and close at the proper times in relation to the position of the pistons. This synchronization is crucial; if the timing belt fails and the camshaft and crankshaft fall out of alignment, it can lead to severe engine damage. Such a malfunction could cause the pistons to collide with the valves, resulting in bent valves, damaged pistons, and potentially, a catastrophic engine failure.
