Timing belts are often referred to as the heart of an engine because they keep various critical engine components in sync. If the timing belt fails, the consequences can be severe. An engine may experience a catastrophic failure, leading to costly repairs and potential damage to other components. This is particularly true for interference engines, where the pistons and valves occupy the same space in the combustion chamber. A timing belt failure in such engines can cause pistons to collide with open valves, leading to bent valves, damaged pistons, and extensive engine repairs.

For Volvo vehicles, the PK belt is engineered to withstand high levels of stress and maintain efficiency over long periods. Given the demanding nature of Volvo cars, the durability and effectiveness of the PK belt are crucial.
