What to do if the car belt slips

1. Turn off the engine and let it cool. Open the engine hood and find the generator belt in front of the engine.

2. Press the belt between the pulleys to check its tension. If pressed more than 1/2 inch, a loose belt will affect generator performance and even damage the generator. belt.

3. Check the generator belt for oil or grease contamination. Turn the belt over to check for cracks in the inner layer, missing rubber parts, and slippage.

4. Loosen the generator adjustment bolt and adjust the pivot bolt.

5. Move the generator inward and loosen the belt. Strip the generator belt from the pulley and remove the generator belt.

6. Compare the removed old belt with the new belt and install the new belt after confirmation.

7. Pull the geneoutward until the belt is taut and make sure the generator belt is installed in the correct position. Adjust the pivot bolt strictly according to the manufacturer's instructions.

8. Start the engine to check the results of the repair, and recheck the belt tightness after stopping the engine.

Car Belt Squealing

In most cases, abnormal belt squealing is caused by the belt being loose. When this happens, it is best to go to a repair shop to have the belt tension adjusted, as the belt will slip and squeal. Once the belt slips, it will extend further due to high friction and the slippage will become more serious, leading to a vicious cycle. Therefore, quick adjustment of belt tension is essential. If you have traveled almost 20,000kilometers and you have never changed the belt before, you should change it now. Don't wait until the belt breaks before replacing it or you'll be in big trouble.

What should I do if the car belt makes an abnormal noise?

A way to judge the abnormal noise of the engine belt

Step 1: If there is an abnormal noise in the engine compartment of the car, it means that the belt is usually loose or poor quality, so first of all check the engine belt. If there are many belts in the car, we cannot know which one is defective. You can start the car and pour water on the belt. If the abnormal noise disappears, there is a problem with the belt. We can see if it is loose or poor quality.

Abnormal noise coming from the engine belt. Water is poured in to increase its viscosity, which actually increases the viscositybelt tee. But once the water dries, the belt will return to its original shape. This is the principle of belt watering.

Step 2: We can also judge which belt has problem by listening to the sound. If there is a problem with the steering wheel, there may be a problem with the steering pump belt. If there is an abnormal noise when the car starts cold, there may be a problem with the engine belt, and we can check it step by step.

A method for determining and solving the problem of abnormal engine belt noise

1. The engine belt squeals.

This is because the joining surface between the belt and the pulley is relatively smooth. This usually happens when the engine speed changes quickly. Sometimes the load on belt-driven accessories increases, which can also cause the belt to idle.

The belt is squeakingA squeaking meansusually that the friction coefficient of the belt surface has been significantly reduced and that it is excessively worn. If there is noise when loading the vehicle, you may want to observe one of the drive belts and notice that the resistance or elasticity of the automatic belt tensioner or tension wheel of the belt will increase abnormally.

Most automatic belt tensioners have a set of belt wear length indicators on the slider located between the bottom of the belt tensioner and the tensioner arm. The mark consists of a pointer and two or three marks indicating the working range of the belt tensioner. If the pointer is outside of this range, the belt may be overstretched and needs to be replaced. On cars without an automatic belt tensioner, use a standard belt tension gauge and measure halfwayin between the two pulleys. If it differs from the standard value, it is better to replace the belt.

2. The motor belt makes a long-term squealing or high-pitched noise

Although the surface of the pulley is stained with sand and other dirt or the worn belt is installed upside down, the The belt will make a long-term high-pitched noise or squeal, but this is usually caused by poorly assembled auxiliary devices.

If the noise occurs in a new car that has not been driven for a long time, it may be caused by poor quality of the original equipment. Check the visual elements that you think could be causing the malfunction. If the above noise occurs in an old car, then you must consider whether you need to completely replace some of the associated accessories of its auxiliary drive unit. Carefully examine any accessories that may have been delicatelyt replaced (such as generator sets, auxiliary steering pumps, etc.). ) and check if their mounting brackets are secure, which can also cause misalignment of the pulley assembly.

Dust or sand between the pulleys and pulleys can also cause loud noises, so if the car is used in a dirty environment, check the surfaces of all pulleys for dust.

Take the example of the timing belt. It must be adjusted immediately after installation. This is why the direction of rotation of the timing belt must be marked. If the timing belt was installed backwards during other maintenance, you will hear a high-pitched squealing sound when the belt is running.

Try reversing the direction of installation of the belt to see if the fault disappears.

3. The motor belt makes a whistling, clicking, roaring sound.t or a chirp.

A persistent whistling or clicking sound that increases with engine speed usually means that the auxiliary rotating mechanism bearings are starved of oil.

Using a stethoscope, we can hear these noises more. Next, remove the drive belt and turn the suspected defective part by hand. If it turns with difficulty or the noise is rough or crackling, do not hesitate to replace the bearings or corresponding parts. However, it should be noted that whenever you replace parts of the auxiliary transmission accessories, remember to replace the belt elastic pulley and automatic elastic device.

As the engine speed increases, the continuous roar gradually turns into a whine, indicating that the corresponding bearing will soon fail.

4. Rumble from the motor belt

The rumble is a noiset typical caused by belt vibration, especially when the auxiliary mechanism transmission system is running. When the engine reaches a certain speed, the noise will increase significantly. The cause of this failure is usually that the drive belt is too loose, too tight, or the belt tensioner and elastic pulley are damaged.

If the car engine belt is abnormal during the warranty period, it is recommended to contact the 4S store as soon as possible to negotiate repairs. Once the warranty expires, you may have to pay for repairs at your own expense. Engine belts are automotive wear products and must be replaced regularly. Replacing the engine belt on some models is very complicated. It is better for car owners to go to a repair shop or 4S workshop for replacement.

This may be because the belt has slipped on the generator and there is strong friction and vibration between the belt and pulley, producing a sound of a certain frequency.

The main cause of belt slippage is belt loosening or aging. Factors that can lead to belt loosening include improper belt tensioner adjustment or insufficient tensioner elasticity. The belt tensioner tension should be adjusted first. If that doesn't work, replace the tensioner.

Belt aging mainly refers to the gradual hardening and loss of elasticity of the belt during long-term use, and the friction between the belt and the pulley is reduced.

In this case, the belt can only be replaced.
