Refrigerant Lines
WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Installation of a new suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.
The condenser to evaporator line contains high-pressure liquid refrigerant upstream of the evaporator core orifice. The A/C manifold and tube assembly is attached to the compressor with O-ring seals.
There is also an additional set of lines that carry refrigerant to the rear evaporator for high-voltage battery cooling. These lines are spliced into the front lines in the engine compartment and the liquid line contains a filter.
