How to Determine When to Replace the Car's Timing Belt?

[StFernando]

Methods to determine when the car's timing belt needs replacement are: 1. The timing belt shows numerous cracks; 2. Slipping or abnormal noise occurs; 3. The car has traveled 60,000 to 80,000 kilometers. The timing belt is a crucial component of the engine's valve system, ensuring accurate intake and exhaust timing by connecting to the crankshaft with a specific transmission ratio. The upper part of the timing belt connects to the timing wheel on the engine cylinder head, while the lower part connects to the crankshaft timing wheel. The timing wheel is linked to the camshaft, with the contact point being the small rocker arm. The rocker arm generates pressure through the power transmitted by the timing belt, performing a lifting function.
