When it comes time for replacement, selecting a quality timing belt is imperative. Aftermarket belts can be less expensive but may not always match the standards of the original equipment manufacturer (OEM) belts.

Additionally, when replacing the timing belt, it is wise to replace related components such as the water pump, tensioners, and pulleys, as these parts can also wear out over time.

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.
