  Q: How to install a new A/C condenser and ensuring proper functionality on Mercury Grand Marquis?

  A:

  The condenser core operates as an integrated cooling device that employs bottom rows for an oil-to-air (OTA) transmission cooler functionality. Before installing a new condenser to detect refrigerant leaks using fluorescent markers it needs to be verified that the dye does not originate from transmission fluid. A suction accumulator replacement should be carried out only when system contamination becomes evident due to failed A/C compressor failure or damaged suction accumulator. Depower the vehicle when fire suppression is present and start by collecting the refrigerant to prevent injuries. Position the vehicle in neutral gear on a hoist before removing the pin-type retainers for the radiator sight shield at both upper and lower positions. After the condenser fittings disconnect remove the pin-type retainers from each of the four lower side deflectors and the bottom cooling module deflector. Disconnect the two transmission cooler line fittings at the condenser before removing its two nuts to disconnect the fittings. Discard the O-ring seals and gasket seals before tightening the new fittings to 15 Nm (11 lb-ft). Begin by removing the four upper side air deflector pin-type retainers then proceed to eliminate the two cooling module bracket bolts (install with 10 Nm torque or 89 lb-in torque). Finally detach the two cooling module brackets. Separate the condenser bolt then disconnect the Power Steering Cooler from the cooling module clips. The cooling module should be tilted slightly backward to obtain the condenser core for removal. Repower the vehicle with its fire suppression system while strictly following any displayed safety instructions. Follow the uninstallation steps in reverse order, while installing the new condenser by using fresh O-ring as well as gasket seals, and providing the refrigerant system with the correct amount of clean PAG oil. The refrigerant system evacuation and leak testing must be performed to finalize the process; then the system can be charged with refrigerant while filling the transmission fluid to its specified level.

  Q: How to service the A/C condenser core on Mercury Grand Marquis?

  A:

  A leak test should be performed first to check for leaks before removing the A/C condenser core. A new suction accumulator/drier needs installation only when system contamination stems from compressor failure or when the suction accumulator/drier shows damage. The first step requires refrigerant recovery followed by battery removal together with the radiator upper sight shield detachment. The A/C condenser core service begins with using peanut fittings to detach the condenser to evaporator tube and the A/C compressor to condenser discharge line. Proceed by taking out the bolts that maintain the radiator supports and the two additional bolts. To remove the A/C condenser core you should first tilt the radiator backward and then pull the core up. Service and install the new A/C condenser core by reversing the removal process while applying PAG Refrigerant Compressor Oil (R-134a Systems) F7AZ-19589-DA (Motorcraft YN-12-C or equivalent that fulfills Ford specification WSH-M1C231-B). After applying oil, lubricate the O-ring seal with the same PAG Refrigerant Compressor Oil.
