The suction accumulator/drier requires removal which begins by disconnecting the battery ground cable followed by performing the Refrigerant Discharging and Recovery Procedure to vacuum out the refrigerant. You must first separate the air cleaner assembly before detaching the speed control servo by disconnecting the electrical connector and unbolt the servo. Afterward, set the servo to the side. The coolant expansion tank/windshield washer reservoir needs to be moved aside with the removal of screws and nuts. Protect the refrigerant tubes from damage by using a wrench while you disconnect both the suction accumulator/drier connector and its refrigerant lines from the A/C cycling switch. The last step involves removing the two screws that fasten the suction accumulator/drier. The installation process begins by following the removal sequence in reverse order unless a new A/C cycling switch is needed which requires transfer to the suction accumulator/drier; then bring sufficient refrigerant oil quantities. The A/C system requires evacuation, leak testing and charge operations following installation steps.

Service of the suction accumulator requires starting by disconnecting the ground cable from the battery and recovering the refrigerant from the system. The speed control servo must be detached after you remove the air cleaner assembly and disconnect the electrical connector and the bolt. Position the servo aside for service. The first step involves setting the coolant expansion tank/windshield washer reservoir to the side after unscrewing and unnutting it. The A/C cycling switch electrical connector requires disconnection but a back up tool protects the tubes as the technician works on the suction accumulator/drier refrigerant lines. The suction accumulator/drier requires removal of its two screws for separation. Reverse the process during installation by applying the A/C cycling switch to the new suction accumulator/drier if required and follow proper procedures for refrigerant oil addition. The completion of the A/C system procedure requires evacuation, leak testing and system charging.

Recovery of refrigerant should be the first step when servicing the suction accumulator in an HVAC system. You should both disconnect the A/C cycling switch electrical connector and apply a back up wrench before taking off the suction accumulator refrigerant lines, discarding their O-ring seals afterward. The suction accumulator installation requires you to remove the screws which hold the bracket in place then remove the suction accumulator itself. Install the suction accumulator by following the reverse order of removal while moving the A/C cycling switch to the new accumulator unit if you add a new accumulator. The installation requires new O-ring seals treated with mineral oil and the refrigerant system needs lubrication with PAG refrigerant compressor oil F7AZ-19D589-DA (Motorcraft YN-12-C) or any equivalent agent that respects Ford specification WSH-M1C231-B. Evacuation follows by leak detection and pressurization completes the refrigerant system process.

Starting the suction accumulator service in HVAC requires first recovering the refrigerant. Start by disconnecting the electrical connector of the A/C cycling switch while performing line removal with a dual-function wrench then discard used O-ring seals. The suction accumulator bracket holds in place through three screws which need removal for extraction of the suction accumulator itself. To install the suction accumulator follow the backward order of uninstallation then transfer the A/C cycling switch to the accumulator during a new installation process. The refrigerant system requires a proper amount of clean PAG refrigerant compressor oil F7AZ-19D589-DA (Motorcraft YN-12-C) or an equivalent which matches Ford specification WSH-M1C231-B along with new O-ring seals pre-lubricated in clean mineral oil. Evacuate the refrigerant system next after which you should perform leak tests followed by system charging.

The servicing operation for the HVAC accumulator begins by removing the battery ground cable. The Refrigerant Discharging and Recovery Procedure should be executed afterwards. Using a back up wrench guard the tubes from damage during the disconnect between the A/C evaporator core fitting and the suction accumulator/drier and A/C cycling switch electrical connector. The suction accumulator/drier separation begins by disconnecting its hose coupling from the A/C manifold then the removal proceeds by unscrewing the mounting bracket bolt for extraction. The new suction accumulator/drier should receive the A/C cycling switch for installation. Installation requires the opposite order of disassembly and professional service of the new suction accumulator/drier to accept PAG compressor oil YN-12-C F7AZ-19589-DA or their equivalent which satisfies Ford specification WSH-M1C231-B.

Use a back-up wrench.

Disconnect the battery ground cable and recover the refrigerant.

Evacuate, leak test, and charge the refrigerant system.

Installation of a new suction accumulator is necessary if there is physical evidence of contamination from a failed A/C compressor or damage to the existing suction accumulator.

Finally, evacuate, leak test, and charge the refrigerant system.

Installation of a new suction accumulator is necessary if there is physical evidence of contamination from a failed A/C compressor or damage to the existing suction accumulator.

For installation, reverse the removal steps, ensuring to lubricate the A/C cycling switch O-ring seal with Motorcraft YN-12c refrigerant oil or an equivalent that meets Ford specification WSH-M1C231-B.

Ensure to install new O-ring seals and lubricate the refrigerant system with the appropriate amount of clean PAG oil or equivalent.
