Pacific Automotive Network Generally speaking, as engine load increases, pulleys will slip. Most of these are caused by belt slack. Check the electric pump belt and generator belt for looseness and that there are no signs of aging or cracks in both belts. The only solution is to replace the power steering pump with a new one.
First, judge whether the abnormal noise only occurs when starting. There will be no abnormal noise after the vehicle starts. If so, the most likely reason is the starter. makes an abnormal noise. Because after starting the engine, the starter stops working and the abnormal noise disappears.
If the abnormal noise persists after starting the engine and changes with the change in engine speed, it is likely that there is abnormal noise in the rotating parts of the engine. For example, there isabnormal noises in the engine belt, air conditioning compressor, engine itself and other parts. We can use a stethoscope to determine the location of the problem. If the abnormal noise has nothing to do with the engine speed but with the gear ratio, the transmission system may be faulty and you should contact a maintenance agency for inspection and repair.
Any noise coming from the car's alternator is abnormal and it is necessary to check and confirm the fault location to prevent the fault from spreading.
There are two causes of abnormal noise in automobile generators:
1
The noise is caused by the generator belt becoming loose when the belt is loosened. , the gap between the belt and the pulley is There will be relative movement, and this movement will produce a special whistling sound, which is mainly produced when the vehicle vistarting or when heavily loaded electrical devices such as headlights are turned on. When business is busy, there will be a smell of burning rubber in the engine room. The inspection method is to spray a small amount of clean water on the generator pulley when there is abnormal noise when starting the vehicle. If the abnormal sound disappears, it is belt noise. The solution to this kind of abnormal noise is to tension the generator belt to the appropriate position to eliminate it.

The sound of loose bearings or lack of oil is a metallic rubbing noise or a continuous brushing noise. Loosen the belt and rotate the generator pulley alone to check for play or abnormal noise. If there is a problem with the generator, the generator must be replaced and repaired.
The automobile generator is the main source of power for the car. Its function is topower all electrical equipment (except the starter) when the engine is running normally (above idle speed) and charge the battery. at the same time.
