What are the regular maintenance items for car air conditioning?
1 Answers
Regular maintenance items for car air conditioning are as follows: 1. Check if the compressor belt is in good condition: If the belt surface and the contact side of the pulley groove appear shiny, and there is a "squeaking" noise when starting the air conditioning, it indicates severe belt slippage. The belt and pulley should be replaced. If the belt is too loose, it should be adjusted; otherwise, it may lead to poor cooling performance of the air conditioning system. 2. Check for oil stains on the hoses and pipe joints of the air conditioning system: If any leaks are found, timely repairs should be conducted. 3. Regularly clean the condenser: Keeping the condenser surface clean facilitates heat dissipation to the outside. Regular cleaning of the condenser surface can significantly improve the cooling efficiency of the air conditioning system. 4. Periodically check the refrigerant level in the air conditioning system: This can be estimated by feeling the temperature difference between the inlet and outlet pipes of the dryer or measured using a manifold pressure gauge. 5. Frequently clean the dust and dirt from the air vents and the cabin: This not only enhances the appearance of the car but also benefits the health of the driver and passengers.
