At what mileage should the timing belt of a car generally be replaced?
1 Answers
The replacement cycle for a car's timing belt is generally recommended when the vehicle reaches 60,000 kilometers. The specific replacement interval depends on the wear and tear of the belt. Typically, the maintenance manual provided by the manufacturer only gives an approximate maintenance cycle. In reality, the quality of belts varies, and aging conditions differ under different usage environments. Therefore, it is advisable to assess each vehicle individually and address any issues promptly. Below is relevant information: 1. Introduction to the timing belt: The timing belt is a crucial component of the engine's valve system. It connects to the crankshaft and ensures the accuracy of intake and exhaust timing through a specific transmission ratio. Belts are used instead of gears for transmission because they produce less noise, offer precise transmission, have minimal variation, and are easy to compensate. 2. Function: When the engine is running, the piston's movement (up and down), the opening and closing timing of the valves, and the ignition sequence must remain synchronized under the "timing" connection. Timing ensures that each cylinder operates precisely: the piston reaches the top dead center, the valve closes exactly, and the spark plug ignites at the right moment.
