How often should the car engine pulley be replaced?

[DiGemma]

Generally, the timing belt should be replaced every 60,000 kilometers for most cars. However, in actual conditions, this figure may vary significantly. If the vehicle is used in harsh environments, such as areas with heavy sandstorms or high temperatures, it may need replacement around 50,000 kilometers. Below are specific situations for replacing the car engine pulley: 1. When inspecting the belt, if defects such as core breakage or groove section cracking are found, immediate replacement is required. 2. The belt must be replaced if the cover layer and cord separate or if the cord frays. 3. When the belt is placed on the pulley, there should be a gap between the inner diameter of the belt and the bottom of the pulley groove. If there is no gap, the belt must also be replaced.
