Section 12-00: Climate Control System, Service | 1996 F-150, F-250, F-350, F-Super Duty and Bronco, F-Super Duty Motorhome Chassis Workshop Manual |
The A/C evaporator core (19860) is a multi-pass plate/fin aluminum core. The condenser to evaporator tube (19835) (inlet) connects to the bottom of the A/C evaporator core and the suction accumulator/drier (inlet) connects to the top of the A/C evaporator core. The outlet of the accumulator/drier then connects to the evaporator to compressor suction line (19867). The evaporator tube is fitted with an A/C evaporator core orifice (19D990) to control refrigerant flow. This A/C evaporator core orifice can be removed from the evaporator core inlet tube for replacement if it becomes necessary. However, a special tool is necessary to prevent breakage of the A/C evaporator core orifice.
