How to Service and Repair the A/C Hose from the Suction Accumulator to the Evaporator in the HVAC System on Mercury Grand Marquis?

The first step for servicing the suction accumulator to evaporator line in the HVAC system involves a refrigerant recovery process followed by disconnecting the spring lock coupling and discarding O-ring seals. The disconnection procedure must be applied to the second spring lock coupling and the suction accumulator-to-evaporator line should be removed before O-ring seals are discarded. Install new O-ring seals that got PAG oil lubrication by following the opposite steps of removal. The correct amount of clean PAG oil should be used for lubricating the refrigerant system. The final steps require evacuation and leaking and charging of the refrigerant system to conclude the process.
