How many kilometers should the engine timing belt be replaced?
1 Answers
Engine timing belts should be replaced at 60,000 kilometers, but the specific replacement interval depends on the wear condition of the belt. Generally, the maintenance manual provided by manufacturers only gives an approximate maintenance cycle. In reality, the quality of belts varies, and aging conditions differ under different usage environments. Therefore, it should be determined case by case based on the vehicle's condition, and any issues should be addressed promptly. Precautions for replacing timing belts: Do not use a hammer to strike during the compaction process: Using hammering for repair not only damages the teeth of the crankshaft gear but also inevitably leads to distortion of the crankshaft position sensor signal, ultimately affecting engine performance. To protect the parts, avoid using a hammer to strike. Understand the vehicle's usage condition and check the engine noise: If a strange "clicking" sound is heard near the top of the timing belt cover, and the noise decreases but persists after engine adjustment, it can be judged as typical tensioner damage. Before pressing the tappet, carefully inspect the condition of the tensioner. Note that the tightening torque of the balance bolt has specific requirements: After replacing the water pump or timing belt, difficulties in starting, reduced power performance, and increased engine noise may occur. Some of these issues are caused by the tightening torque of the balance bolt not meeting the required value. Some maintenance personnel may not even know the tightening torque requirements and simply tighten it, thereby creating potential hazards.
