2006 Mercury Mountaineer A/C Accumulator Parts Questions & Experts Answers

• Q: How to Service the A/C Accumulator in the HVAC System on 2006 Mercury Mountaineer?

  A: The HVAC refrigerant servicing process for the suction accumulator must start with refrigerant recovery. Starting by disassembling the PCM then the low-side service port stem bracket bolt needs to be tightened at 8 Nm (71 lb-in). Reinstallation follows the same torque specifications. Detach the electrical connector of A/C cycling switch and remove suction accumulator bolt by tightening it to 9 Nm (80 lb-in) for the installation phase. Tighten the suction accumulator stud to 9 Nm (80 lb-in) after its replacement. The suction accumulator-to-compressor line bracket nut should be removed from the condenser-to-evaporator line at 4.6L vehicles. The technician should first disconnect the two suction accumulator fittings by removing their nuts before disposal of O-ring seals and proper tightening of new fittings to 8 Nm (71 lb-in) during reinstallation. Disassemble the suction accumulator bracket bolt as well as the suction accumulator. The final step for installation involves the reversal of current procedures followed by new O-ring seal installation and correct PAG oil lubrication of the refrigerant system. The refrigerant system needs evacuation followed by leak testing and charging during completion.
