It connects the crankshaft, which drives the pistons, to the camshaft that controls the opening and closing of the valves. If the timing belt were to fail or slip, it could result in the valves being out of sync with the pistons, potentially leading to catastrophic engine damage. This is especially critical in high-performance applications, such as racing, where precision timing is essential for optimal engine performance.
