A broken timing belt will cause the timing belt to break while driving, which will cause the engine to lift the valve, requiring the engine to be overhauled.
Under normal circumstances, if the timing belt is maintained normally and the timing belt is replaced according to the kilometers or years specified by the manufacturer, the timing belt will not break.
Generally, if the timing belt breaks, the car will lose power, accompanied by strong abnormal noises, and there will also be abnormal noises when it is started again.
The timing belt is an important part of the engine valve system. It is connected to the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the intake and exhaust times.
