Oil Injection Using a Dye/Lubricant Injector
WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Fluorescent refrigerant system dye is added to the refrigerant system at the factory to assist in refrigerant system leak diagnosis using a Rotunda-approved UV black light. It is not necessary to add additional dye to the refrigerant system before diagnosing leaks, even if a significant amount of refrigerant has been removed from the system. Replacement suction accumulators and receiver/driers are shipped with a fluorescent dye wafer included in the desiccant bag which dissolves after approximately 30 minutes of continuous A/C operation. It is not necessary to add dye after flushing the refrigerant system because a new suction accumulator or receiver/drier is installed as part of the flushing procedure. Replace hose/accumulator, receiver/drier or receiver/drier element.
NOTE:
The dye/lubricant injector is included as part of the 219-00069 R-134a Loop/Add On Injector Kit-Set.
NOTE:
Before using the R-134a Loop/Add On Injector Kit-Set for the first time, refer to the equipment manufacturer's instructions on evacuation of non-condensable gases from the hoses.
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.
NOTE:
Refrigerant system pressure should be between 413-551 KPA (60-80 psi) at 24 ° C (75 ° F) with the engine off and cool.
- 1.
Evacuate the refrigerant system. For additional information, refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging .
- 2.
Assemble the dye/lubricant injector using the correct adapters to match the amount of refrigerant compressor oil to be injected.
- 4.
Fill the dye/lubricant injector with the correct amount of clean, new PAG (polyalkylene glycol) oil.
- 5.
Install the dye/lubricant injector between the low-side service gauge port valve and the refrigerant service station or manifold gauge set.
- 6.NOTE: Make sure all tools and hoses are clear of the engine cooling fan and drive belt before starting the engine. Failure to keep tools and hoses clear from the engine cooling fan and drive belt results in damage to the tools and/or vehicle.
Open all valves and charge the refrigerant system. For additional information, refer to Air Conditioning (A/C) System Recovery, Evacuation and Charging .
