1. Timing Belt The timing belt is crucial for coordinating the movement between the engine's crankshaft and camshaft. Its primary function is to ensure that the engine's valves open and close at the proper times during each cylinder's intake and exhaust strokes. This synchronization is essential for optimal engine performance. A faulty timing belt can lead to severe engine damage because if it breaks, the valves and pistons can collide, resulting in costly repairs. Typically, manufacturers recommend replacing the timing belt every 60,000 to 100,000 miles, but it's essential to consult the owner's manual for specific guidelines related to your vehicle.
