Generally speaking, the replacement cycle of the timing belt is 60,000 to 100,000 kilometers. However, the specific replacement time should be determined according to the vehicle's maintenance manual and combined with the actual vehicle usage scenario. If the vehicle is often driven in harsh environments, such as high temperature, high load or frequent start and stop, the wear rate of the timing belt will be significantly accelerated. In this case, it is recommended to check the timing belt at 60,000 to 80,000 kilometers, and consider whether to replace it based on the inspection results. For vehicles with low mileage but long service time, even if the mileage does not reach the recommended replacement standard, Você deve ir a uma compra profissional 4S regularmente para verificar o envelhecimento da correia dentada . durante a inspeção, se as rachaduras forem encontradas na superfície da correia dentada e um forte cheiro de borracha for emitido, ela deve ser substituída imediatamente para evitar possíveis riscos de segurança .}}
Além disso, se o manual de manutenção do veículo mencionar que a correia dentada precisará ser substituída regularmente, o veículo usará uma correia dentada; if the manual does not mention the timing belt replacement cycle, then the vehicle is likely to use a timing chain. Although the timing chain is basically "maintenance-free" in design, car owners still need to pay attention to it, because during long-term use, the timing chain may become loose due to stretching, causing engine performance to decline and even triggering the engine fault light.
