Q: What are the steps and precautions for servicing and repairing the A/C Accumulator on Lincoln MKZ?
A: Service and repair of the A/C accumulator requires caution against exposure to outside air while also performing it as the final step during work involving multiple A/C components. The A/C system needs to begin its vacuum process automatically after receiving its new A/C accumulator because delayed operation risks desiccant moisture contamination. The replacement of an A/C accumulator becomes necessary only when physical indications point to failed A/C compressor contamination or accumulator damage due to both physical harm and moisture exposure when all refrigerant escapes and permits atmospheric pressure intrusion. The accumulator must stay intact when there exists any positive refrigerant pressure before repair work begins. The recovery of refrigerant should occur first followed by hoisting the vehicle into the NEUTRAL gear and extracting the lower radiator air deflector. Begin by unscrewing and removing the plastic accumulator cap and try to remove the accumulator plug again only after opening a refrigerant system fitting to release any vacuum pressure. The accumulator plug can be removed after pushing it upwards and separating the snap ring so you can insert the bolt from the A/C desiccant cartridge service kit at its center for easier removal. A suitable tool should be used to grasp the grab handle of the accumulator for its removal. The installation requires following the removal steps backward while applying residual refrigerant oil to the O-ring seals of the accumulator plug and verifying that the system contains the appropriate quantity of clean PAG oil. Shut down the system before performing an evacuation of the refrigerant system and leak tests followed by charging operation.
Q: How to Service the A/C Accumulator in the HVAC System on Lincoln Town Car?
A: Service work on the suction accumulator in HVAC should start with vehicle installation on a hoist, keeping it in NEUTRAL. Recover all the refrigerant before you detach the outlet side of the suction accumulator fitting but throw away the O-ring seals. The inlet fitting should then be detached along with replacement of both O-ring seals. Separate the electrical connector of the A/C cycling switch and unscrew the three mounting bolts of the suction accumulator. When reinstalling these bolts apply 15 Nm (11 lb-ft) of torque to them. The removal procedure for the suction accumulator should be reversed for installation while also installing new O-rings and using the correct amount of clean PAG oil for refrigerant system lubrication. The conclusion includes evacuating as well as testing for leaks and charging the refrigerant system.
Q: Is a New Desiccant Cartridge Necessary When Servicing the A/C Accumulator on Lincoln Navigator?
A: To replace the desiccant cartridge during A/C accumulator servicing, you need to check for physical signs of contamination that stem from an A/C compressor failure or cartridge structural damage. The A/C accumulator becomes contaminated by moisture exclusively when refrigerant losses reach total levels and system pressures equalize with atmospheric pressure for longer than one hour. The A/C accumulator desiccant cartridge should stay where it is when the system still contains positive refrigerant pressure before maintenance work. The first step involves eliminating the condenser core from service. Start by first removing the plastic accumulator cap through unscrewing and then detach the accumulator plug using the same procedure. The snap ring removal needs a plug up-push while adding an M5 bolt at its center to create plug removal capability. A proper tool should be used to handle the accumulator cartridge grab handle before removing the cartridge. The installation process requires reverse following removal steps and requires application of accumulator plug O-ring seals with oil found in the accumulator.
