How often should a car's timing belt be replaced?
1 Answers
Generally, it is common to replace the timing belt every 60,000 to 80,000 kilometers, but some may require replacement at longer intervals such as 80,000 to 100,000 kilometers. The exact replacement time is not entirely uniform, as each car brand and model has its own specific requirements. The precise timing should always be based on the "Owner's Manual" provided with the vehicle at the time of purchase. Below is more information about timing belts: 1. Function of the timing belt: The timing belt is a consumable automotive part made of rubber, which will degrade over time. It connects the camshaft and the crankshaft, controlling the opening and closing of the valves and coordinating the rotation of the crankshaft with the up-and-down movement of the pistons. 2. Effects of a broken timing belt: A broken timing belt will cause the valves to open and close at the wrong time, and the pistons to move out of sync. This misalignment can lead to the valves and pistons colliding, resulting in damage to both components. In such cases, the engine will cease to function and may require a major overhaul. 3. Impact on the engine: If the timing belt breaks, the engine will not operate properly, leading to symptoms such as unstable idling, poor acceleration, or failure to start. The engine may stall immediately. In multi-valve engines, a broken timing belt can cause the pistons to bend the valves, and in severe cases, the engine may be rendered completely inoperable.
