Section 78 (HVAC Systems (Service Information)): Plumbing: Operation

High pressures are produced in the refrigerant system when the A/C compressor is operating. Extreme care must be exercised to make sure that each of the refrigerant system connections is pressure-tight and leak free. It is a good practice to inspect all flexible hose refrigerant lines at least once a year to make sure they are in good condition and properly routed.

Depending on vehicle, model and market application, refrigerant lines are connected to each other or other A/C system components with block-type or quick-connect type fittings. To ensure the integrity of the refrigerant system, flat gaskets and O-rings are used to seal the refrigerant system connections.

The refrigerant lines and hoses cannot be repaired and, if faulty or damaged, they must be replaced.
