How to Add Refrigerant Oil to Car Air Conditioning?
2 Answers
Car air conditioning refrigerant oil addition method is: 1. Open the car hood and locate the high and low pressure pipes of the air conditioning system; 2. Check if the filling valve is qualified; 3. Connect the red and blue pipes of the air conditioning pressure gauge equipment to the high and low pressure pipes of the air conditioning system, and connect the yellow pipe to the vacuum oil extractor for 15 minutes; 4. Turn off the vacuum machine and disconnect the high pressure pipe; 5. Add the appropriate amount of refrigerant oil through the compressor channel. Car air conditioning, short for car air conditioning device, is used to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment to a better state, which can provide passengers with a comfortable riding environment and reduce travel fatigue.
I tried adding car air conditioning refrigerant oil myself before, and it ended up being a bit of a mishap. Adding refrigerant oil is done through the low-pressure port of the AC system, requiring a filling gun to inject it slowly while ensuring the system is vacuumed and checked for leaks. Otherwise, if air mixes with the new oil, all the effort goes to waste. Personal experience: preparation is key—buying the right oil and tools, watching tutorial videos—but the actual process is stressful. Using the wrong tools can cause refrigerant leaks, leaving you with a strong odor and doubled repair costs. Nowadays, I just take it to a repair shop—quick and hassle-free. Professional technicians can get it done in half an hour. My advice to car owners: don’t skimp on this expense; safety comes first.
