How Often Should the Engine Belt Be Replaced?

[AutumnLynn]

For ordinary vehicles, the engine belt needs to be replaced after one and a half to two years of use. Alternatively, if the mileage reaches 60,000 kilometers, the belt can also be replaced. The belt is a crucial part of the engine's valve timing system. It connects to the crankshaft and ensures accurate intake and exhaust timing through certain transmission mechanisms. Belts are preferred over gears due to their low noise, precise transmission, minimal dimensional changes, and ease of compensation. Therefore, regular belt replacement is essential. Hazards of not replacing the belt: Belt failure usually occurs due to cracks or aging, causing the belt to become stiff. Without maintenance, the belt may lose teeth, leading to timing belt slippage in the engine. In severe cases, the belt may break entirely. If the belt breaks, its inertia causes the camshaft to continue rotating freely, resulting in misalignment between the piston and valve movements. This misalignment can cause continuous collisions, potentially damaging both components severely.
