[SanKendra]

A car's timing belt should be replaced approximately every 60,000 kilometers. The timing belt is a crucial component of the engine's valve train system. As a rubber part, its functions include: 1. Ensuring the accuracy of intake and exhaust timing; 2. Synchronizing the engine's ignition and cylinder movement; 3. Guaranteeing smooth power output from the engine. The method for replacing the timing belt is as follows: 1. Lift the vehicle and remove the right front wheel fender liner; 2. Remove the generator belt and generator belt tensioner; 3. Loosen the crankshaft pulley bolt; 4. Open the engine hood and remove the water reservoir; 5. Remove the engine mounting bracket and the protective cover on the timing belt; 6. Unscrew the generator mounting bolt and remove the generator; 7. Remove the cylinder block mounting bracket and take off the crankshaft pulley; 8. Rotate the crankshaft to the top dead center position of the cylinder and mark it; 9. Remove the timing belt and timing tensioner to complete the replacement.
