Q: How to service the A/C Hose from the condenser to the evaporator on Ford Ranger?
A: Start the condenser to evaporator line servicing operation by recovering all refrigerant from the system. The evaporator core spring lock coupling needs to be detached first before discarding the O-ring seals. After disconnecting the condenser core line you should remove the component together with the accompanying O-ring seal. The installation process starts by performing the opposite steps of removal while applying clean mineral oil to new O-ring seals before installation. The correct amount of clean PAG refrigerant compressor oil needs to be used to lubricate the refrigerant system with F7AZ-19D589-DA (motorcraft YN-12-C) or WSH-M1C231-B equivalent that meets Ford specification. The refrigerant system requires evacuation followed by a leak check and two subsequent recharging the system. You must replace the suction accumulator only when contamination from a faulty A/C compressor or any damage to the accumulator occurs. Workers should use F73Z-19577-AA (Motorcraft YN-9-A) for lubricating R-134a refrigerant system O-ring seals yet must avoid adding this chemical to the refrigerant system as an A/C compressor lubricant.
Q: How to service and repair the evaporator outlet A/C hose on Ford Explorer?
A: The first step to maintain the evaporator outlet line consists of removing the air cleaner and its outlet tube. Proceed to disconnect the right-hand wheel speed sensor electrical connector and gather the refrigerant from the system. Follow the procedure by removing elements in this specific sequence. During installation use the appropriate amount of clean PAG Refrigerant Compressor Oil F7AZ-19589-DA (Motorcraft YN-12-C) which fulfills Ford specification WSH-M1C231-B to lubricate the refrigerant system. The A/C fittings need new O-ring seals that received clean mineral oil treatment before reinstallation after disconnecting any fittings. Refrigerant system evacuation should be followed by leak testing then final charging completes the process. Customers must replace their suction accumulator with a new one exclusively when present evidence shows either a broken A/C compressor or damaged suction accumulator. The R-134a refrigeration system requires F73Z-19577-AA (Motorcraft YN-9-A) only as a tool to lubricate O-ring seals while this product must never be added into the R-134a refrigerant system as compressor lubrication.
Q: How to Service and Repair the A/C Hose on Ford Mustang?
A: Refrigerant recovery should be the first step in servicing or repairing the HVAC hose/line according to proper discharging and recovery procedures. Unlatch the air breather before disconnecting the electrical connector which connects the Mass Air Flow (MAF) sensor. To work on the HVAC hose/line you must first disconnect the crankcase ventilation tube along with the outlet tube clamp. You must first remove the air cleaner outlet tube before you can detach the line from the condenser by removing its nut and then disconnect the line and unfasten the clamp to extract the line. Installation should follow the reverse sequence of removal steps while completing necessary evacuating along with charging procedures.
