How to Ensure Proper Functioning of the A/C Accumulator in a Mercury Grand Marquis?

The first step to service the HVAC accumulator requires executing the Refrigerant Discharging and Recovery Procedure. Use spring lock coupling general steps to disconnect the evaporator to compressor suction line from the suction accumulator/drier. Perform the suction accumulator/drier separation from the A/C evaporator core while using a back up wrench to protect both fitting and tube from harm. Preparation of the suction accumulator/drier consists of unscrewing the mounting bracket retaining screw which connects to the A/C evaporator core before extracting the assembly. The next step requires removal of the insulation cover from the suction accumulator/drier and separation of the A/C accumulator mounting bracket from it. The installation process should be done in reverse order by first servicing the suction accumulator/drier with PAG compressor oil YN-12-C F7AZ-19589-DA or equivalent that follows Ford specification WSH-M1C231-B. The O-ring seal demands application of the same PAG compressor oil during installation while using a back up wrench to protect the fitting torsion from damage.

How to Service the A/C Accumulator in the HVAC System on Mercury Grand Marquis?

The initial step for suction accumulator HVAC system service requires placing the vehicle at neutral in a hoist position. It is essential to disable the fire suppression system because this move protects employees from severe harm. Recovery of the refrigerant must be completed before you disconnect the suction accumulator outlet fitting and get rid of the O-ring seals. The next step requires removal of the suction accumulator inlet fitting along with the throwing away of its O-ring seals. First disconnect the A/C cycling switch electrical connector then remove and tighten to 15 Nm (11 lb-ft) the three suction accumulator bolts. Sever the suction accumulator from the system and activate the fire suppression system if present while observing all security notifications. The installation of the new suction accumulator starts by reverse following the removal instructions while adding new O-ring seals before lubricating the refrigerant system precisely with clean PAG oil. The refrigerant system requires evacuation and leak testing then charging as the last step.
