How to remove and replace the A/C accumulator in a Mercury Mountaineer?

Have the air conditioning system dis-charged by a dealer service department or by an automotive air conditioning shop before proceeding. Remove the air filter housing. Remove the front grille. Disconnect the condenser line and the evaporator line from the top of the accumulator. Remove and discard the old O-rings. Push the radiator air deflector forward to access the accumulator mounting nut on the backside of the radiator support panel. Remove the accumulator mounting bolts and remove the accumulator. Note: The lower mounting bolt must be accessed from behind the radiator support panel while the upper bolt can be accessed from inside the engine compartment. Replace all old O-rings. Before installing the new O-rings, coat them with refrigerant oil. Tighten the inlet and outlet air conditioning line mounting nuts to the torque. Installation is otherwise the reverse of removal. Take the vehicle to the shop that discharged it and have the system evacuated and recharged.

Mercury Mountaineer A/C Accumulator

The Mercury Mountaineer A/C Accumulator safeguards the SUV climate system by removing moisture and grit before refrigerant returns to the compressor, mounted in the low pressure line between evaporator and compressor, the A/C Accumulator uses a desiccant bag to soak up water and trap debris, avoiding corrosion and ice. Every Mercury model year of the Mountaineer relies on this cylinder as a small reservoir that meters oil laden vapor back to the compressor so the pump never runs dry. Though similar in shape to the receiver drier located on the high pressure side, that unit conditions liquid after the condenser while the A/C Accumulator treats vapor before compression. Only the A/C Accumulator protects against harmful liquid slugs that could fracture compressor pistons. Once the desiccant saturates or debris builds, replacing the Mercury Mountaineer component is vital because flushing cannot free what the bag has captured. Installing a fresh A/C Accumulator restores drying capacity, keeps refrigerant clean, and upholds the long term reliability Mercury drivers expect from their Mountaineer air conditioning system.

We provide a wide range of Mercury Mountaineer A/C Accumulator at the optimal prices. If you need Mercury Mountaineer A/C Accumulator, you can shop with confidence on our website. All our OEM parts come with a manufacturer's warranty and are delivered to your doorstep with a fast delivery service.
