RC.600.373 926003RJ1A 926001KA3A 926001HC2D Car AC Compressor For 10S11C For NISSAN VERSA WXNS028

Parameter:

Here are the key precautions to consider when replacing a car air conditioning compressor:

1.Safety First

• Disconnect the battery to avoid electrical hazards.
• Wear safety gloves and goggles to protect against refrigerant and sharp components.

2.Recover Refrigerant Properly

• Use an EPA-approved recovery machine to safely extract refrigerant (e.g., R134a or R1234yf) before disassembly.
• Never vent refrigerant into the atmosphere—it’s illegal and environmentally harmful.

3.Inspect the AC System

• Check for contamination (metal debris, black dust) indicating compressor failure.
• Flush the system if debris is present to prevent new compressor damage.
• Replace the receiver-drier/accumulator and expansion valve/orifice tube (critical for moisture and debris control).

4.Correct Oil Quantity & Type

• Drain and measure the old compressor’s oil; add the manufacturer-specified amount of PAG or ester oil to the new unit.
• Incorrect oil can cause lubrication failure.

5.Proper Installation

• Align belts/pulleys correctly to avoid premature wear.
• Tighten bolts to the specified torque to prevent leaks or damage.
• Replace O-rings/lubricate them with refrigerant oil to ensure seals.

6.Vacuum & Recharge

• Evacuate the system with a vacuum pump (30+ minutes) to remove air/moisture.
• Recharge with the exact refrigerant amount listed on the vehicle’s underhood sticker.

7.Leak Test & Performance Check

• Use a leak detector or UV dye to verify no refrigerant leaks.
• Test AC operation: Check cooling performance and abnormal noises.

8.Dispose of the Old Compressor Responsibly

• Follow local regulations for recycling/disposing of refrigerant and metal parts.
