Refrigerant Lines
WARNING: This page is about a different car, the 2003 Ford RV Cutaway, 2003 Ford Econoline, 2003 Ford E550 Super Duty, 2003 Ford E450 Super Duty, and 2003 Ford Cutaway. 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 (19835) contains high pressure liquid refrigerant upstream of the evaporator core orifice.
The compressor manifold and tube assembly is attached to the A/C compressor and has the following features:
- The upstream side contains low pressure refrigerant gas.
- The downstream side contains high pressure refrigerant gas.
- A serviceable high pressure A/C charge port valve is located on the downstream side.
- The downstream side also contains a fitting used to mount the pressure cutoff switch. A long-travel Schrader-type valve stem core is installed in the fitting so that the pressure cutoff switch can be removed without discharging the A/C system.
