What are the symptoms of a broken engine timing belt?

[JamesAnn]

Symptoms of a broken timing belt: 1. The car may experience unstable speed and a tendency to stall while driving. 2. Sometimes, you may feel a lack of power during acceleration, and in severe cases, you might notice engine shaking. Consequences of a broken timing belt: 1. When the timing belt breaks, the connection between the camshaft and the crankshaft is interrupted. Without power from the camshaft, the valve group it controls will fail to open and close properly, and the pistons may bend the valve stems due to inertia. 2. If the engine is running at high RPM, the pistons may also suffer from burn damage, and in severe cases, this can lead to complete engine failure. 3. If you notice the timing belt has broken, pull over safely and wait for assistance. 4. Regularly inspect the condition of the timing belt. Check for oil or coolant stains on the belt surface—if present, clean them thoroughly. Also, examine the belt teeth for wear and look for surface cracks. Replace the belt immediately if any damage is found to prevent engine failure. 5. The typical lifespan of a timing belt is around 3 years or 60,000–80,000 kilometers, depending on the vehicle model and actual usage. Refer to the car's maintenance manual for specific guidance.
