Must be replaced in the engine compartment.
1. Open the engine cover and remove the generator belt secured by screws.
2. Tighten the belt with a sleeve and remove it from inside the generator to buckle the engine timing belt.
3. Remove the gasket inside the motor belt.
4. Pull the new belt outward from the generator and press the seal onto the belt inside the engine.
5. Extend the motor clamp so that the motor belt is secure.
6. Install the rear of the engine cover onto the engine and secure it with screws.
7. Check engine performance and make sure the belt is installed correctly.
The reasons for abnormal noise in the car are as follows:
1. The engine is overheating, check the cooling system. The exhaust system is blocked. In the exhaust system, check whether the exhaust pipeent is broken. The vacuum tube is leaking or broken.
2. The generator bearing may be damaged.
3. Engine oil pressure is too low.
4. The engine is overheated, the engine has carbon deposits, and the oil quality is not good. It is necessary to add premium oil.
5. The relationship between abnormal noise and engine speed. The existence of the most common abnormal noises in engines depends on the condition of the engine speed.
6. Many abnormal noises on the motor are obviously related to its load
7 The relationship between abnormal noise and temperature: It makes noise at low temperatures, and when the temperature rises. , the sound decreases or disappears when the temperature increases, and the sound decreases or disappears when the temperature drops.
8. The relationship between abnormal noise and engine duty cycle. Abnormal engine noise failure is oftenobviously related to the operating cycle of the engine, especially the abnormal noise of the crank rod mechanism. and the valve system are both related to the duty cycle.
9. The relationship between abnormal noise and engine parts. When the motor makes abnormal noise, it will inevitably produce a certain degree of vibration. The characteristics and location of the vibration can help diagnose the cause of the abnormality. noise.
How to Fix Abnormal Engine Noise
To check abnormal engine noise, you must have: The manual intuitive method is to determine directly by looking, touching, testing, listening. , etc., or using simple tools. Technical condition of the machine and methods of failure. Its distinctive feature is that it does not require special equipment, and the accuracy of the diagnostic results depends on the technical level and practical experience of the diagnostic personnel.
1.Observation: Observe the condition of mechanisms, assemblies and parts with suspected defects, such as the indicated values of each instrument, cracks and deformations of the body, the color of the exhaust gases emitted from the muffler and stains d dripping oil and water, then combine it with other relevant situations to analyze and judge the running condition of the engine.
2. Touch: That is, touch the temperature and vibration of possible defective parts with your hands, so as to determine the tightness of the fit, the size of the bearing gap, the weight balance. parts, etc.
3. Test: Use various testing methods to fully reveal the fault phenomenon, such as honking the horn, turning on the ignition switch or light switch, "turning on" the spark plug, quickly increasing the engine speed, or If necessary, the assembled assembly or parts can be remplaced for comparative tests.
4. Listening: It is to judge which ones are normal and which ones are abnormal based on the sounds made by the engine under different working conditions and different parts and rules of sounds. For example, if there is a knocking noise in the cylinder, if there is a whooshing noise or a “pop, pop” sound in the exhaust muffler, etc.
