UNDERBODY AUXILIARY A/C LINES

The underbody auxiliary A/C lines carry refrigerant to the auxiliary A/C evaporator inlet line, and away from the auxiliary A/C evaporator outlet line. The auxiliary underbody lines have the following characteristics.
- The underbody auxiliary A/C evaporator inlet line consists of two separately serviceable pieces.
- The fore auxiliary A/C evaporator inlet line carries high pressure refrigerant liquid from the condenser to evaporator line to the aft auxiliary A/C evaporator inlet line.
- The aft auxiliary A/C evaporator inlet line carries high pressure refrigerant liquid from the fore auxiliary A/C evaporator inlet line to the auxiliary evaporator inlet.
- The underbody auxiliary A/C evaporator outlet line consists of two separately serviceable pieces.
- The aft auxiliary A/C evaporator outlet line carries refrigerant vapor from the auxiliary A/C evaporator outlet to the fore auxiliary A/C evaporator outlet line.
- The fore auxiliary A/C evaporator outlet line carries refrigerant vapor from the aft auxiliary A/C evaporator inlet line to the manifold and tube assembly.

UNDERBODY HEATER LINES

The underbody auxiliary heater lines have the following features.
- The underbody auxiliary heater inlet line consists of two separately serviceable assemblies.
- The fore underbody auxiliary heater inlet line is a steel tube assembly that carries coolant from the front heater core inlet line to the aft underbody auxiliary heater inlet line.
- The aft underbody auxiliary heater inlet line carries coolant from the fore underbody heater inlet line to the auxiliary heater core.
- The aft underbody auxiliary heater inlet line consists of a steel tube with formed rubber hoses at each end. The rubber hoses are attached and sealed to the tube using constant tension pop clamps.
- The aft underbody auxiliary heater outlet line carries coolant from the auxiliary heater core to the fore underbody auxiliary heater outlet line.
- The aft underbody auxiliary heater outlet line consists of a steel tube with formed rubber hoses at each end. The rubber hoses are attached and sealed to the tube using constant tension pop clamps.
- The fore underbody auxiliary heater outlet line is a steel tube assembly that carries coolant from the aft underbody heater outlet line to the front heater core outlet line.
