2008 Mercury Grand Marquis A/C Accumulator Parts Questions & Experts Answers

• Q: How to Service the A/C Accumulator in the HVAC System on 2008 Mercury Grand Marquis?

  A: 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.
