  Q: How to Service and Repair the A/C Orifice Tube in the Evaporator Core on Ford F-350 Super Duty?

  A:

  Refrigerant recovery should begin as a first step when servicing the evaporator core orifice. A technician must remove the right-hand fender splash shield in 6.4L diesel vehicles before proceeding. The service starts with turning off the evaporator core orifice access fitting then throwing away the O-ring seal. A thorough examination of the evaporator core orifice should come before the removal process starts. The Fixed Orifice Remover/Installer should be used to extract the orifice while maintaining a fixed position on the T-handle and rotating the tool body. You should use the Broken Orifice Remover to handle damaged orifices by inserting its small end into the aperture and then continuing with standard usage protocols. Clean PAG oil should be used to lubricate the new evaporator core O-ring seals before placing the orifice into the Fixed Orifice Remover/Installer for installation. Reinstall the evaporator core orifice access fitting using a new O-ring seal for every vehicle type including 6.4L diesel vehicles. During this process replace the right-hand fender splash shield. Lubrication of the refrigerant system needs the appropriate amount of clean PAG oil before eliminate remaining vacuum while leak-checking all components and charging the system with refrigerant.
