How Do You Maintain An Air Compressor?
The function of the air compressor is very different from other parts inside the car. The parts of the air compressor are special and cannot be used for the car engine. Therefore, its maintenance is also slightly different from other accessories.

- Check compressor belt tension:
The tension of the automotive compressor belt is 376N±50N. If the belt tension is too large, it is easy to cause early failure of the compressor pulley bearing. It is manifested by the loud noise of the compressor. If it is not repaired in time, it will cause damage to the clutch. If the belt tension is too small, the belt will slip, causing the speed of the compressor to drop, and the cooling effect will be poor.
- Evaporator maintenance and maintenance:
Like the condenser, the evaporator is a heat exchanger, and it is required to keep the vents clean, the drains unblocked, and the blower running normally. When the car is at maximum cooling, pay attention to check whether there is engine hot water leaking in through the warm water valve, so as not to affect the cooling effect.
- liquid storage tank:
The liquid storage tank should be replaced in time after two years of normal use which can be purchased from air compressor parts online stores. Because the desiccant in the liquid storage tank will fail after about two years of use. If it absorbs moisture supersaturated, the dry bag is easy to burst, and the desiccant powder will block the pipeline. Every time the pipeline is disassembled for repair or cleaning, it must be replaced with a new fluid storage tank.
- Throttling device:
The throttling device used in the front air conditioner of the car is a throttle tube, while the rear air conditioner uses an expansion valve. When cleaning the pipeline, it is best to replace the throttling device at the same time to prevent the pipeline from being blocked again or even damaging the compressor. No matter what kind of expansion valve is used, it is absolutely not allowed to adjust the opening of the expansion valve in order to pursue the cooling effect, otherwise, the light one will affect the cooling effect, and the severe one will cause the liquid shock of the compressor.
- Condenser maintenance and maintenance:
The main thing is to ensure that the condenser has maximum airflow. Therefore, it is usually necessary to pay attention to whether the condenser is operating normally. Clean the condenser channel frequently, and don't be blocked by sundries, oil, mud, and insects. Pay attention when cleaning:
1. Do not use a high-pressure water gun, otherwise, it will easily damage the heat dissipation fins and reduce the heat dissipation effect.
2. In addition to cleaning the surface of the condenser, it is also necessary to clean the gap between the condenser and the radiator. If the blockage here is serious, it will often cause the engine water temperature to be too high and affect the cooling effect.
- Air conditioning system connector:
Check whether there is any oil stain on the joints of the pipelines. Oil stains indicate that there is leakage at this part, and repairs should be carried out in time. Do not use self-made tools or other substitutes, otherwise, the lock spring in the joint will be easily damaged, resulting in refrigerant leakage, and once the damage cannot be repaired, the air-conditioning pipe assembly must be replaced.
