Cars are important to us. After all, cars are bought with money. There is a lot of knowledge about cars that we need to know. Everyone must pay more attention to car knowledge! Today I will introduce it to you. How to add oil to the compressor of automobile air conditioner.
1. Shut down cars. Open the front cover. You check whether the air conditioning system meets the requirements.
2. You open the protective cover of the low-pressure end filling port of the car air conditioning system. Connect the low-pressure end nozzle with a barometer. Place a thermometer in the center of air conditioner outlet in the car.
3. Start the car. Turn the air circulation and wind speed of the air conditioner to the maximum. Door closed. The engine must remain in operation throughout the filling process.

4. After the system runs for 3 minutes. You can record the temperature of the air outlet of the air conditioner.
5. Check and confirm whether the air conditioning pressure is in normal working state. If it is confirmed to be normal, the maintenance oil can be filled. The normal working range of air conditioner pressure reference (low pressure end): 25-45PSI. When the ambient temperature is 24 ℃-30 ℃, the ideal filling pressure range is 45-50PSI. Under the condition of high temperature, high humidity or no exhaust. The pressure at the low-pressure end may rise by 5-10PSI. In the absence of professional guidance. Do not fill curing oil at pressures below 25PSI or above 50PSI. Out of the range of 25-50PSI. This means lack or excess of refrigerant and mechanical failure.
How to add oil to the compressor of car air conditioner: Add maintenance oil.
1. Start filling after checking and confirming that the air conditioning system is suitable for conditions. The engine needs to be running at all times during filling. The air conditioner is set to the maximum state.

2. Connect the product to the filling tool. Insert the filling tool into the curing agent bottle. Tighten the connection threads of the curing agent bottle and the filling tool. Make sure that the filling tool is fitted with the inlet hose and the connection is tight.
3. During operation, the filling tool is parallel to the ground. You pull the filling tool to exhaust air from the hose. It needs to be pulled 2-4 times for the first time. This fills the hose with curing oil to ensure that all air in the hose is removed. This is important.
4. Connect the hose joint of the filling tool to the low-pressure end filler port.
5. Pull the filling tool 12 times. Fill the air conditioning system with maintenance oil.
6. Remove the hose connector of the filling tool from the low-pressure end filler. Cover protection cover for low-pressure end filler.
7. Wait for 3-5 minutes and record the temperature of the air outlet in the car.
Make sure you use professional tools and industry standard barometers. The installation tool can only be filled from the low-pressure end nozzle of the air conditioner. It is dangerous for the high-pressure end. It is worth noting that safety glasses should be used during filling.
These are the steps for adding engine oil to the car air compressor. I hope this article can help you.
