How to Add Refrigerant Oil to an Automotive Compressor?

1Answers
Aurora
08/25/2025, 11:48:18 PM

Discharge the refrigerant from the crankcase into the condenser to create a vacuum in the crankcase. Prepare the lubricating oil. Use your finger to block the suction pipe opening, then start the compressor to evacuate the air from the crankcase. Immerse the blocked pipe opening into the oil. Once immersed, the oil will be drawn into the crankcase through the pipe. Observe the oil level indicator to ensure the oil reaches the specified level. Open the suction and discharge stop valves to complete the oil addition process.

What Causes Squeaking Noises While Driving a Car?

Reasons for squeaking noises while driving a car: 1. It may be due to poor retraction of the brake caliper, causing the brake disc and brake pads to remain in slight friction; 2. It could be caused by hard spots on the surface of the brake pads or small particles like sand getting between the brake disc and brake pads; 3. A broken shock absorber can result in no damping or rebound when the car goes over bumpy roads, making it prone to abnormal noises when passing speed bumps or rough surfaces. Many people think that abnormal noises while driving must be due to suspension issues, but a car's suspension includes components like links, springs, shock absorbers, and stabilizer bars. Any abnormality in these suspension components can cause the car to feel very loose or even produce abnormal noises while driving.
