A/C Refrigerant System, Servicing
HD = high pressure side
ND = low pressure side
NOTE:
- Always observe safety measures.
- A/C system components identified with an asterisk (*) may only be serviced or replaced after properly discharging refrigerant system.
- A/C system components not identified with an asterisk (*) can be serviced or replaced without discharging refrigerant system.
- Compressors supplied as replacement parts already contain the full quantity of refrigerant oil required for the A/C system.
- Do not add refrigerant to the A/C system. Always discharge, evacuate and recharge system.
- The tightening torques and O-ring diameters given also apply to the threaded connections for the refrigerant lines between components.
- Install only O-rings that are approved for use with refrigerant R134a (currently color-coded red, light purple and dark purple).
