  4. Using a lint-free clean, dry cloth, clean the sealing surfaces of the A/C refrigerant components.
  5. Carefully install the new seal washer onto the A/C refrigerant component.

    The washer must completely bottom against the surface of the fitting.

  6. IMPORTANT: After tightening the A/C components, there should be a slight sealing washer gap of approximately 1.2 mm (3/64 in) between the A/C line and the A/C component.
  7. Assemble the remaining A/C refrigerant components. Refer to the appropriate repair procedure.
