spring if the old one is damaged or missing.

Remove any surface residue from the inside of the coupling by polishing with 400-grit emery cloth (or equivalent). Polish the surface by
using a twisting motion so that any scratches made will not cross the O-rings sealing surface. Finish polishing with 600-grit emery cloth or
equivalent. Remove all polishing residue from the fitting with a lint free cloth.
8. Use the (A) Plastic O-ring Tool supplied with the O-rings kit or equivalent to remove the (B) O-rings seals from the male fitting.
NOTE: Do not use metal O-rings tools. They can cause axial scratches across the O-rings grooves resulting in refrigerant leakage.

Use Motorcraft Refrigerant Oil YN-12b, F2AZ-19577-AC or equivalent meeting Ford specification WSH-M1C231-B to lubricate seals.
NOTE: Use only specified O-rings seals. Use of any O-rings seal other than the one specified may allow the connection to leak intermittently
during vehicle operation.
