If the timing belt were to slip or break, the consequences could be catastrophic. For interference engines, a timing belt failure can result in the pistons striking the open valves, leading to extensive internal damage. Conversely, in non-interference engines, a broken timing belt will simply cause the engine to stop running, but the risk of serious damage remains. Therefore, the timing belt's integrity and functionality are vital for a vehicle's overall health.
