Common A/C Service Issues

• Moisture contamination in the A/C system
• Improper refrigerant metering through a worn expansion valve
• Service delays when matching compressor oil and sealing parts separately

Installation Notes

Verify the vehicle’s refrigerant type and compressor oil specification before service. This kit is intended for R134a systems using PAG 46 oil, and the expansion valve uses sealing washer inlet and outlet connections. Replace all sealing components during installation, evacuate the system, and recharge to the vehicle’s specified service amount after repairs.
