Ford 6C2Z-19860-C
Evaporator Core, Front

New suction accumulator/driers should only be installed for the main climate control system when contamination or damage becomes evident. Perform a leak test before removal of the core when there is reason to suspect a leak in the A/C evaporator. Start the process by recovering then discharging the refrigerant from the system. The needed screws must be removed so you can take out the battery and battery tray. Use a wrench to disconnect compressor suction and evaporator discharge lines by placing the wrench on both sides of their fittings to avoid damage and move the oil fill pipe and windshield washer reservoir cover out of the way. The A/C system maintenance should start with standard vehicles by removing the suction accumulator/drier line spring lock coupling followed by unscrewing the screw to disconnect the condenser to evaporator tube. First disconnect and then remove the isolator from the compressor discharging lines after separating the refrigerant lines from the condenser core. You must first remove the six and five screws on the evaporator cover before taking off the support bracket by unscrewing it from the evaporator core housing. You should uninstall the A/C evaporator core while preserving the integrity of its cooling fins. During A/C evaporator installation service the core with PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or an equivalent compatible with Ford specification WSH-M1C231-B. Proper sealing is essential while paying attention to the cooling fins. Return the evaporator cover after installing its screws until you place the evaporator core housing support bracket back before screwing it down. Before installing new O-ring seals users should apply the same PAG Refrigerant Compressor Oil to lubricate them. Reinstall the discharge line of the compressor and place the compression isolator in its position. Follow the applicable procedure to install the screw into the spring lock coupling between the auxiliary evaporator and compressor tube. Lubricate the O-ring seals of the compressor suction line before completing its installation and proceed by lubricating the O-ring seals of the evaporator discharge line. The final steps include reattaching the windshield washer reservoir cover and oil fill pipe with the battery tray and battery before performing evacuation and charging on the A/C system.

The first step to service or repair the evaporator core in auxiliary climate control system is to remove the air conditioning and heater assembly. You must disconnect the evaporator core spring lock couplings which require disposal of the O-ring seals. First displace the heater water hoses before disconnecting the evaporator case cover through screw removal. You should first remove the cover along with the A/C evaporator core by taking off its seal after cover removal. One must take out the thermostatic expansion valve (TXV) after peeling off the seal for a second time. The reversal of removal steps should be followed for installation.

The main step to fix the evaporator core in the system's main climate control is to recover refrigerant first. The service starts with removing both the battery and tray by unscrewing their mounting screws. Clear the space for oil fill pipe and windshield washer reservoir cover by unfastening all screws and relocating them aside. You should disconnect the evaporator discharge line and compressor suction line while using wrenches on their fittings to avoid harm during the process. Standard A/C system owners should disconnect their suction accumulator/drier line spring lock while auxiliary A/C-heater system drivers should remove their screw. Use a wrench to disconnect the condenser to evaporator tube from both its sides. Van owners with 4.2L engine power need to untwist the condenser core refrigerant lines while all other vehicles require isolation of the compressor discharge line through screw removal. Proceed by first disconnecting the screws that attach the evaporator core housing support bracket before moving to the evaporator cover where six and five screws need to be removed. You should extract the A/C evaporator core while avoiding harm to its cooling fins. Before usage of the new A/C evaporator core it needs to be serviced with PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C) or an equivalent meeting Ford specification WSH-M1C231-B. After servicing, install evaporator core and seal while paying attention to cooling fins. Remount the evaporator cover after attaching it with the original screws from removal. The evaporator core housing support bracket gets reinstalled together with screws when you install the new condenser core refrigerant lines after applying PAG Refrigerant Compressor Oil to the O-ring seals as a lubricant. The task involves joining the compressor discharge line and adding the compressor discharge line isolator. The 4.2L engine installation requires condenser and evaporator tube connection followed by new O-ring seal lubrication according to the initial procedure. The compressor suction line must be connected through the auxiliary evaporator to compressor tube spring lock coupling if relevant while lubricating all O-ring seals. You should finish the installation process by connecting the evaporator discharge line followed by the windshield reservoir cover installation and adding an oil fill pipe and battery tray and battery before doing system evacuations and charging.

Recover the refrigerant.

Disconnect the evaporator inlet fitting by removing the screw and disconnecting it, discarding the O-ring seal.

Conduct a vacuum leak test before removal.

Begin by recovering the refrigerant and disconnecting the battery.

Reverse the removal procedure to complete the process.

Remove the air cleaner assembly, battery, and battery tray by removing the bolts.

Install the new components by reversing the removal procedure.

Position the heater hoses aside.

Remove the A/C and heater assembly.

Remove the A/C evaporator core by first taking off the seal and then extracting the core itself.

Remove the 2 bolts and tighten it to 9 Nm (80 lb-in) upon reinstallation.

Remove the junction box bracket bolts and the junction box bracket itself, tightening to 28 Nm (21 lb-ft) upon reinstallation.
