How to Determine When a Car's Timing Belt Needs Replacement?

[DelLogan]

Methods to determine when a car's timing belt needs replacement: If the belt shows significant cracks, slippage, or abnormal noises, it needs to be replaced. Nowadays, many vehicles no longer use belts for their timing systems, as most car engines have switched to timing chains. In most cars, belts are still used only for components like the generator, compressor, and power steering pump. Belts are wear-prone parts that can deteriorate and wear out over time. It is recommended that car owners check the belt's condition during every maintenance service and replace it promptly if it shows signs of failure. During normal use, if you hear a squeaking sound coming from the engine compartment, it indicates severe belt slippage, and the belt should be replaced immediately.
