Q: How to Properly Maintain the A/C Accumulator in the HVAC System on a Ford Explorer?
A: Refrigerant recovery must begin the process of servicing the suction accumulator in HVAC systems. Start by removing the air cleaner together with radiator grille followed by five pin-type retainers and air deflector. You should first remove the suction accumulator bracket nut before disconnecting the two A/C fitting nuts by torquing them to 8 Nm (71 lb-in) before reinstallation. The suction accumulator service requires two steps: removing the suction accumulator bracket bolt before taking out the suction accumulator. The reinstallation process follows the reverse of removal actions by using fresh O-ring seals which must be coated in clean mineral oil before installation. PAG Refrigerant Compressor Oil F7AZ-19589-DA (Motorcraft YN-12-C) with equivalent Ford specification WSH-M1C231-B (or equivalent about WSH-M1C231-B) should be used for A/C compressor lubrication and in combination with Refrigerant Compressor Oil F73Z-19577-AA (Motorcraft YN-9-A) to lubricate the R-134a refrigerant system O-ring seals. The last step involves evacuation followed by a leak-check then charging of the refrigerant system with the needed amount of fresh PAG oil. The replacement of suction accumulator translates to physical evidence that emerges from a bugged A/C compressor or destruction from a suction accumulator.
Q: How to Service the A/C Accumulator in the HVAC System on Ford Mustang?
A: Starting the accumulator servicing for HVAC system operation requires following the Refrigerant Discharging and Recovery Procedure first. The first step is to remove the cycling switch after you disconnect its connector. Disconnecting the suction line followed by removing its clamp nut allows you to separate the accumulator from the evaporator. The service of the accumulator begins by reversing the removal procedure after removing the accumulator from the system. Lubricate the O-ring with PAG Compressor Oil or YN-12c or F7AZ-19589-DA or an equivalent product that fulfills Ford specification WSH-M1C231-B.
Q: How to Properly Maintain the A/C Accumulator in the HVAC System on a Ford Ranger?
A: 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.
