Since the engine belt is an important part of the engine, in order to avoid engine problems, the 4S store will require that it is best to replace the timing belt after driving about 60,000 kilometers. If it is a new car, the timing belt must be replaced. The belt usually runs 80,000-100,000 kilometers. After replacing the timing belt, due to the depreciation, use, installation and other problems of the car, the service life of the timing belt will be reduced accordingly. In order to ensure the service life of the engine, it is recommended that the timing belt must be replaced every one and a half to two years. , or when driving about 60,000 kilometers, you need to replace the timing belt.

Once the timing belt breaks, the camshaft valve sequence will not operate according to the timing. At this time, it is very likely to cause the valve and piston to collide and cause serious damage to the engine, so the timing belt must be in accordance with the timing. Replace it within the mileage or time specified by the original factory, otherwise the consequences will be very serious.

There are two fundamental reasons for the loud engine noise: excessive carbon deposits in the engine. The engine oil is inappropriate or the oil is dirty.

In addition, most of the engine noise is caused by abnormal engine noise:

1. Engine lower protection Board screws are loose. A relatively common minor fault is tightening or adjusting the engine lower guard plate screws.

2. The engine claw pads are aging. The claw pads play a role in supporting the engine and can only be replaced after aging.

3. The plastic parts in the engine compartment are loose. For example, the engine cover, air intake pipe, etc. can be tightened.

4. The engine belt makes abnormal noise. Including power belts, generator belts, etc. If the belt is old or is too loose or too tight, it will produce abnormal noise. Replace or adjust the tightness.

5. Engine knocking. There is too much carbon deposit inside the engine or the fuel usage is substandard. Clean carbon deposits and replace fuel.

6. Abnormal valve noise. Especially after the car is cold, the valve will make a "click-click" sound, and then it will be fine when the car is warmed up. This is because the engine oil is deposited in the oil pan and is not "pressed" in time when the engine is started. But if the valve keeps ringing, you should consider changing to a thicker engine oil (for how to choose engine oil, please refer to "How to Choose the Engine Oil Correctly").

7. Engine "backfire" failure. The engine will make a "puff-puff" sound, which may be caused by excessive carbon deposits on the valves or improper timing adjustment. Clean the carbon deposits on the valves and adjust the valve timing.

8. The engine is missing a cylinder. If a certain cylinder does not ignite, most likely the spark plug or ignition module is faulty and can be replaced.

9.Bearing noise. There will be regular "buzzing" sounds in bearings, such as engine tensioners, idlers, generators, etc. This can be solved by replacing relevant parts.
