Fitment Notes

• Always match OEM reference number(s) and vehicle details before ordering. Confirm exact fitment using VIN, engine code, or chassis number if multiple variants exist.

• Supplied with 135 ml oil fill quantity - additional system oil may be required depending on the condensation and receiver/dryer state.

Installation / Use / Maintenance Tips

• Air conditioning refrigerant must be safely recovered by a qualified technician before the system is opened - do not vent refrigerant to atmosphere.
• Flush the air conditioning system fully to remove debris or contamination when replacing a failed compressor.
• Replace the receiver/dryer or accumulator and the expansion valve / orifice tube when fitting a new compressor.
• Verify the correct oil type and quantity for the refrigerant being used (R134a vs R1234yf) before charging.
• Rotate the new compressor by hand before installation to distribute the oil evenly, and evacuate the system fully before recharging.
