What are the consequences of a broken engine timing belt?

[MiguelLee]

If the timing belt breaks, the valves and ignition system will fail to operate properly. In severe cases, it may lead to engine repairs or even replacement. Generally, a broken timing belt can cause abnormal noises when starting the car, inability to accelerate or sluggish acceleration, or ignition misfires, which may result in engine failure. Below are the reasons: 1. The timing belt controls the opening and closing of the valves. When it breaks, the pistons and valves may collide, causing varying degrees of damage to these internal components and affecting the engine's normal operation. 2. Timing belts are not highly durable, and breakage is common. Therefore, when a vehicle has been driven for 60,000 to 100,000 kilometers, it is advisable to promptly visit an auto repair shop to check for wear on the timing belt and replace it immediately if necessary. Most 4S shops recommend that owners replace the timing belt every 60,000 kilometers to prevent unexpected accidents.
