Most modern vehicles are equipped with a timing belt instead of a timing chain due to its quieter operation and lighter weight. However, timing belts are not meant to last indefinitely. Depending on the vehicle's make and model, these belts typically need to be replaced every 60,000 to 100,000 miles. Failing to replace a timing belt on schedule can lead to catastrophic engine damage, including bent valves and a complete engine failure, which can be incredibly costly to repair.

The PK belt is vital for efficient vehicle operation. It transfers power from the engine to essential components, allowing them to function correctly. For instance, the alternator relies on the PK belt to generate electricity, while the water pump is crucial for maintaining engine temperature. If the PK belt fails, it can lead to a chain reaction of problems, including engine overheating, battery failure, and loss of power steering, significantly affecting the vehicle's driveability and safety.
