A/C Discharge Line - Installation
INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system See: Service and Repair/Refrigerant Oil Level
. Failure to properly adjust the refrigerant oil level will prevent the A/C system from operating as designed and can cause serious
A/C compressor damage.
CAUTION: If replacing the A/C discharge line, be sure to use the discharge line designed for the A/C compressor in the vehicle. If replacing
the 6SEU16 compressor, be sure to use the latest level of A/C discharge line during replacement. Failure to use the correct A/C
discharge line could result in possible discharge line and/or compressor damage.
NOTE: When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be
added to the refrigerant systemSee: Service and Repair/Refrigerant Oil Level .
NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is disconnected. Failure to replace
the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.
1. If removed, install the A/C pressure transducer (2) onto the A/C discharge line (3). Tighten the A/C pressure transducer securely.
2. Position the A/C discharge line into the engine compartment.
3. Remove the tape or plugs from the discharge line fitting and the condenser port.
4. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it and a new gasket onto the discharge line fitting. Use only the specified
O-ring as it is made of a special material for the R-134a system. Use only refrigerant oil of the type recommended for the A/C compressor in the
vehicle.
5. Reach down through the opening between the radiator and the front fascia and connect the A/C discharge line to the A/C condenser (4).
6. Install the nut (5) that secures the A/C discharge line to the A/C condenser. Tighten the nut to 5 Nm (44 in. lbs.).
7. Connect the wire harness connector (1) to the A/C pressure transducer.
8. Install the upper radiator closure panel See: Body and Frame/Spoilers, Flaps, and Air Dams/Air Dam/Service and Repair/Upper Closure Panel -
Installation.
