How to Add Refrigerant Oil to the Car Compressor?
2 Answers
Methods for adding refrigerant oil to the car air conditioning compressor: 1. Direct Injection Method: Simply pour the refrigerant oil directly into the compressor through the plug opening, which is very convenient. 2. Vacuum Suction Method: (1) Evacuation: Use a dedicated vacuum tool to remove the air inside the air conditioning system. (2) Negative Pressure Suction: After the air inside the air conditioning system is removed, use negative pressure to suck the refrigerant oil into the compressor through a yellow hose. (3) Adding Refrigerant: Once the refrigerant oil is completely sucked into the compressor, the addition of refrigerant oil is complete, and then the refrigerant can be added directly.
As an experienced DIY car enthusiast, I've got some insights on adding refrigerant oil to the compressor. The first step is determining whether the AC system needs oil replenishment - typically required after compressor replacement or when leaks are detected. Choosing the correct oil is crucial; consult the manual to select either PAG or POE type refrigerant oil. After cleaning residual oil from the system, locate the compressor's filling port and slowly inject the oil using professional tools - overfilling beyond specifications can damage components. Remember to start the engine and test AC cooling performance after refilling to ensure smooth operation. Last time I did it myself, I added about 30ml which took me an hour or so, saving some money. However, this is a delicate procedure - without proper tools or experience, it's better not to risk it to avoid AC failure or compressor damage.
