WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If fluorescent leak detection dye is also to be added during A/C charging, the dye may be added to the dye/lubricant injector along with the refrigerant oil.

Evacuate the refrigerant system. For additional information refer to AIR CONDITIONING (A/C) SYSTEM RECOVERY, EVACUATION AND CHARGING .
Assemble the dye/lubricant injector using the correct adapters to match the amount of PAG oil to be injected.
Verify that all the valves on the dye/lubricant injector are closed.
