How to Add Refrigerant Oil to a Car Air Conditioner?
3 Answers
Car air conditioner adding refrigerant oil method is: 1. Open the car hood and locate the air conditioner's high and low pressure pipes; 2. Check if the filling valve is qualified; 3. Connect the air conditioner's high and low pressure pipes to the red and blue hoses on the air conditioner pressure gauge equipment, then connect the yellow hose to the vacuum oil extractor for 15 minutes; 4. Turn off the vacuum machine and remove the high pressure pipe; 5. Add the appropriate amount of refrigerant oil through the compressor channel. The functions of the air conditioner are: 1. To cool, heat, ventilate and purify the air inside the car; 2. To provide a comfortable riding environment for passengers, reduce driver fatigue and improve driving safety.
Adding refrigerant oil to a car's air conditioning system requires special attention as it directly affects the efficiency and safety of the refrigeration system. I've done this many times myself. The standard procedure is to first connect a professional vacuum pump to evacuate the entire AC system, which removes air and moisture. Then, use an oil injection tool to add the refrigerant oil through the low-pressure port. The oil quantity must strictly follow the vehicle manual's specifications - too much increases resistance, while too little accelerates compressor wear. Remember to operate slowly during the process to prevent air bubbles from entering. After completing the oil injection, recharge the refrigerant and finally test the system pressure. Safety goggles and gloves are essential during operation as refrigerant oil can irritate the skin upon contact. Don't attempt this casually on your own - inaccurate oil measurement or system leaks can quickly damage the compressor. It's best to have this done by a qualified repair shop with proper tools and experience.
Hey buddy, if you're thinking about adding refrigerant oil to your AC, listen up—I've been there with my old car, and you can't afford to be careless. First, locate the low-pressure port in your car, then slowly pour in the oil using a specialized funnel or oil injection tool. Make sure the oil is specifically designed for AC systems—don't use any other type. The quantity must be precise; check the manual for exact values, as they vary by car. Honestly, though, the process is pretty tricky. Last time I tried DIY, I nearly messed up—the system pressure went off, and the compressor started humming. Sometimes it's safer to just pay a pro. Refrigerant oil is crucial—it lubricates the compressor components and boosts cooling efficiency. Without enough, your AC won’t blow cold air. Remember, you’ll at least need a vacuum pump for the job. If you don’t have the tools, don’t force it—better safe than sorry.
