• Q: How to Service and Repair the A/C Hose for the Auxiliary Climate Control Evaporator Inlet on 2001 Ford F-350 Super Duty?

  A: Service and repair of the auxiliary climate control evaporator inlet line requires a first step of completing refrigerant discharging and recovery followed by vehicle raising and support. Perform this task by unbolting the fender splash shield through the removal of front and rear right-hand wheels together with four screws, three bolts, and three pin-type retainers. The service begins with vacuum reservoir retaining nut removal then the ABS wiring harness disconnect and removal of the fender splash shield. The evaporator inlet line spring lock coupling requires disconnection before removing the five line bracket retaining nuts and five line brackets by inserting a screwdriver into the stud hole for twisting motion which requires pulling off the bracket before the stud to prevent damage. The installation process starts by removing the auxiliary evaporator inlet line fitting and throwing away the defective line. The first step for installation involves attaching the rear auxiliary evaporator inlet line to the auxiliary evaporator inlet line and lubricating the O-ring seals with PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or an equivalent meeting Ford specification WSH-M1C231-B. Afterward, snap the rear line into the line brackets then install the front auxiliary evaporator inlet line through the wheel well for connection while reapplying lubrication to the O-ring seals. Next attach the rear line into its brackets while mounting the brackets onto the studs before working on the nuts with loose tensions. Connect the two auxiliary evaporator inlet lines while applying wrenches to maintain fitting safety and apply seal lubrication to both rings. Operate the five bracket nuts gently to prevent breaking the stud from the floor pan. The repair begins with restoring the ABS wiring harness before placing the fender splash shield correctly into position and tightening the vacuum reservoir retaining nuts. In the final step, replace both right-hand wheels then lower the vehicle after securing the fender splash shield with its four screws three bolts and three retaining pins. Proceed to evacuate and leak test and charge the A/C system.
