The belt may have slipped on the generator, causing 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.
How to identify the Bora generator belt is broken
Abnormal belt noise Pacific AutomotiveNetwork in most cases is that the belt is loose. In this case, it is better to go to the hospital. The repair shop should adjust the belt tension because the belt will make a squealing noise when it slips. Once the belt slips, the friction and high temperature will cause the belt to stretch further and. the slippage will become more serious, entering a vicious circle. Therefore, quick adjustment of belt tension is essential.
Most of the time, when the belt makes an abnormal noise, it is because it is loose. In this case, it is better to go to the repair shop to adjust the belt tension, because the belt will produce noise. a squeak if it slips. Once the belt slips, it will cause the friction temperature to be further stretched and slip more seriously, entering a vicious circle. Therefore, quick adjustment of the tension of the belt is essential. If you have driven almost 20,000 kilometers and have never changed the belt before, you should normally replace the belt now. Don't wait for the belt to break before replacing it and you'll be in big trouble.
How to judge the abnormal noise of the engine belt: Step
First: If there is an abnormal noise in the engine compartment of the car, it is usually because the belt is loose or of poor quality. You must therefore first check the engine belt. If there are multiple belts in the car and we cannot determine which belt is the problem, we can start the car first and then pour water on the belt. If the abnormal noise disappears, there is a problem with this belt. , and we will. You will be able to check if it is loose or of poor quality.
The motor belt makes an abnormal noise. Water itith water will increase its viscosity, which effectively improves the viscosity of the belt. But after the water dries, the belt will return to its original state. This is the principle of belt watering.
Step
Second: We can also determine which belt has the problem by listening to the sound. If there is an abnormal noise when the air conditioner is turned on, there may be a problem with the air conditioner compressor belt. If there is a problem with the steering wheel turning, there may be a problem with the power steering pump belt. If the car makes abnormal noises when starting from cold, there may be a problem with the engine belt. We can check it step by step.
Diagnosis and solutions to abnormal engine belt noise faults: The engine belt squeaks: This is due to relatively mild wear of the joining surface of the belt and pulley. This usually happenst when the engine speed changes quickly. Sometimes the increased load on belt-driven accessories also causes belt noise. The belt makes a squeaking noise. In this case, it means that the friction coefficient of the belt surface is significantly reduced and the belt is excessively worn. If the vehicle makes noise when loaded, you may want to observe one of the drive belts. You will find that the resistance or elasticity of the automatic belt tensioning device or the belt tensioning wheel will increase abnormally.
Most automatic belt tensioners have a set of belt wear length indicators somewhere between the bottom and arm of the tensioner, along the slide. The mark consists of a pointer and two to three marks that indicate the operating range of the belt tensioner. If the pointer is at dOutside of this range, the belt is probably too tight and needs to be replaced. On vehicles without an automatic belt tensioner, use a standard belt elongation tape measure halfway between the two pulleys. If there is a difference from the standard value, it is best to replace the belt.
Long squealing or squealing noises from the engine belt: Although the pulley surface is stained with dirt such as sand or the worn belt is installed upside down, the belt will also emit long squeaks or squeaks. noises. This is generally due to incorrect mounting of the auxiliary device. If the noise occurs in a new car that has been on the road for some time, it may be caused by poor quality original equipment.
The Kia Sorento 2.4 generator makes noise When the car is cold, it makes a humming sound. When the car is hot, it emitsa noise k when the accelerator is lightly. press. Please respond.
Pacific Automotive Network 1. First, remove the mounting bolts on the generator shaft. 2. Then pull the generator idler pulley outward to make it easier to wind the belt. 3. Then wrap the generator belt around the generator shaft. 4. Then wrap the belt around the two idler pulleys of the generator. 5. Then install the generator shaft housing and the generator belt is installed.
If there is an abnormal noise in the engine compartment of the car, it is usually because the belt is loose or of poor quality, so check the engine belt first. If there are multiple belts in the car and you cannot determine which belt is the problem, you can start the car first and then pour water on the belt. If the abnormal noise disappears, it means thatthere is a problem with this belt. I can take a look. Is it loose or the quality is bad?
The motor belt makes an abnormal noise. Dousing it with water will increase its viscosity, which effectively improves the viscosity of the belt. But after the water dries, the belt will return to its original state. This is the principle of belt watering. Whatever the timing belt or chain, they are invisible from the outside and are covered by a side cover. You can tell this by looking at the material and tightness of the cover that covers the timing belt or chain. If the cover is plastic and just attached with a few simple screws, there is the timing belt inside.
If it is made of iron or aluminum, has many screws and is tightly sealed, it is a chain. The belt cover only blocks dust and foreign objects, tannote that the chain cover not only blocks foreign objects, but also has a sealing function because it is lubricated by engine oil and contains organic oil. Look for the exposed accessory belt, which is the large cover near the accessory belt.
Look at the maintenance manual. In the maintenance content it is written how much. If the timing belt is replaced after a few kilometers, it is the belt. If it's not specified, it's the channel.
Why does the belt make an abnormal noise when starting a cold car?
1. The generator belt may be making noise, or the generator bearing may be making noise.
2. When the car is cold, pour water on the belt. If it stops ringing, the belt is ringing. Check if there is still noise when the car is warmed up and also use the method of pouringr water on it. After diagnosing the belt noise, it is necessary to replace the belt.
3. If the sound remains the same after being sprayed with water, it means that the generator bearing is noisy. Then it's time to disassemble and inspect the generator.
The sound produced by friction between the timing belt and the timing cover. Such problems can damage the timing belt in advance. If it breaks, it will damage the engine valve and require servicing. The water pump makes an abnormal noise. But most of them happen when the car is hot. If the sound is not loud, you can ignore it and replace the generator belt or generator tensioner when the timing is changed to 9 weeks/km/6 years. As long as the sound is not loud, you can ignore it. Will not affect belt life. Even if it breaks, you can replace it immediatelyimmediately before the battery runs out. Generally there will be no loss of other components. Even if the power steering pump is disconnected, it will not work. How to confirm if the generator belt makes abnormal noise: Pour water on the generator belt before starting, turn on and the chirping noise disappears. After the water dries for 1 or 2 minutes, the chirping will reappear. Pour a little more water and the abnormal noise disappears again.
