Determining when a car's timing belt needs replacement involves the following methods: 1. The belt has numerous cracks; 2. The belt slips or makes unusual noises. The steps to replace a car's timing belt are: 1. Lift the vehicle and remove the right front wheel liner; 2. Remove the alternator belt and the alternator 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 alternator mounting bolt and remove the alternator; 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 the timing belt tensioner for replacement.
When it's time to replace the timing belt, I mainly judge it based on mileage and belt condition. My car manual states that it generally needs to be replaced every 60,000 to 100,000 kilometers, depending on the vehicle model—don’t take this lightly. Frequent drivers know that if there’s an unusual squeaking sound when starting the engine or a noticeable lack of power during acceleration, it’s likely a belt issue. I’ve experienced it myself—fine cracks or wear marks on the belt mean it’s time for an immediate check. It’s simple to do it yourself: just open the hood and inspect the belt surface. But it’s best to have a professional use tools for a thorough test. If you delay replacement and the belt snaps, the engine valves and pistons can collide, leading to costly repairs. So regular maintenance is key—skimping on small costs can lead to big troubles.
