A timing belt is a critical component in an internal combustion engine that synchronizes the rotation of the crankshaft and camshaft(s). Checking the timing belt is necessary to ensure that the engine is running correctly and to prevent catastrophic engine failure.
A properly functioning timing belt ensures that the valves open and close at the correct time in relation to the piston’s movement. This precise timing is essential for efficient engine operation, fuel economy, and emissions control. Neglecting to check the timing belt can lead to skipped or broken teeth, which can cause the valves to hit the pistons and result in extensive engine damage.
