Precursors of a broken timing belt, consequences of a broken timing belt

Timing belts are rubber products, which are prone to aging and fracture after a long time of use, which will affect the operation of the car engine, and cause many failures in the car, and some signs will also occur. What are the signs of a broken timing belt? Ignoring these precursors can have adverse consequences. Let's find out below.

Symptoms of a Broken Timing Belt

If the car is runningFindThere are the phenomenon of unstable speed and easy flameout. Sometimes you will feel weak in acceleration. In severe cases, you may feel the engine jitter. In these cases, it is very likely that there is a problem with the timing belt, which may be cracked or dropped. Teeth, which are all precursors to belt breakage.

Consequences of a broken timing belt

The timing belt is broken, and the connection between the camshaft and the crankshaft is interrupted. At this time, the camshaft has no power to drive, and the valve group controlled by it fails to open and close, and the piston will bend the valve stem due to inertia. If the speed is high, the piston may also cause ablation damage, which will directly lead to the scrapping of the engine in severe cases. If you find that the timing belt is broken, you should pull over in time and wait for rescue. In general, the condition of the timing belt should be checked regularly, and the surface of the belt should be checked for oil and coolant stains. If there is, it should be completely removed; check whether the tooth shape of the belt is worn and whether there are cracks on the surface. If there is, it should be replaced in time to avoid breakage. Engine failure.

The service life of the timing belt is generally about 3 years or 60,000-80,000 kilometers, depending on the model and the actual use of the car, refer to the car maintenance manual. In addition, the tightness of the belt is also very important. If it is too tight, the tension will be too large and it will easily break; if it is too loose, it will make noise during operation, and it is easy to slip. Insufficient power, increased fuel consumption, etc., it is easy to jump teeth when the engine load is large or power shocks, which may cause the top valve, thereby damaging the engine. It is best to adjust the belt tension to a 10mm slack when it is pressed down and can be turned 90 degrees.
