REMOVAL 1. DISCHARGE REFRIGERANT FROM REFRIGERATION SYSTEM HINT : At the time of installation, please refer to the following item. Evacuate air from refrigeration system. Charge system with refrigerant and inspect for leakage of refrigerant. Specified amount: 600 ±50 g (21.16 ±1.76 oz.) 2. DISCONNECT LIQUID TUBE 5VZ-FE Shown a. Using SST, remove the piping clamp. SST 09870-00025 (Liquid tube) 1. Insert SST to piping clamp. HINT : Confirm the direction of the piping clamp claw and SST using the illustration showing on the caution label. 2. Push down SST and release the clamp lock. NOTE: Be careful not to deform the tubes, when pushing SST. 3. Pull SST slightly and push the release lever, then remove the piping clamp with SST. 4. Remove the piping clamp from SST. b. Disconnect the both tubes.

The manual climate control system heats and/or cools the vehicle depending on the function selector switch position and the temperature selected. The function selector switch position determines heating or cooling and air distribution. The temperature control setting determines the air temperature. The heater blower motor switch varies the blower motor speed. Component Locations Air Conditioning System Components Refrigeration System Components – 5.4L And 6.8L (7.3L Diesel Similar) Refrigeration System Components The A/C refrigerant system is a clutch cycling orifice tube type. The system components are: A/C compressor. A/C clutch. A/C condenser core. A/C evaporator core. Suction accumulator/drier. Connecting refrigerant lines. The refrigeration system operation is controlled by the following: A/C evaporator core orifice. A/C cycling switch. A/C pressure cut-off switch. The refrigerant system incorporates an A/C compressor controlled by an A/C cycling switch. The A/C cycling switch senses pressure in the suction accumulator/drier to

1. RUN ENGINE AT APPROX. 1,500 RPM 2. OPERATE AIR CONDITIONER AT MAXIMUM COOLING FOR A FEW MINUTES 3. CHECK AMOUNT OF REFRIGERANT Observe the sight glass on the receiver. Insufficient* (1) Check for gas leakage with gas leak Bubbles present in sight glass tester and repair if necessary (2) Add refrigerant until bubbles disappear Refer to items 3 and 4 No bubbles present in sight glass None, sufficient or too much Empty or nearly empty (1) Check for gas leakage with gas leak No temperature difference between tester and repair if necessary compressor inlet and outlet (2) Add refrigerant until bubbles disappear Refer to items 5 and 6 Proper or too much Temperature between compressor inlet and outlet is noticeably different (1) Recover refrigerant Immediately after air conditioner is turned Too much (2) Evacuate air and charge proper off, refrigerant in sight glass stays clear amount of purified refrigerant When air conditioner is turned off, Proper refrigerant foams and then stay clear

Compressor Assembly Removal 1. Run engine at idle with A/C ON for 10 minutes . 2. Disconnect negative (-) cable at battery. 3. Recover refrigerant from refrigeration system using recovery and recycling equipment. NOTE: The amount of compressor oil at removed must be measured and the same amount must be poured when installing the compressor. 4. Remove P/S pump referring to Step 4) to 7) of “Removal” in “P/S Pump Removal and Installation:”. NOTE: It is not necessary to drain P/S fluid. 5. Disconnect magnet clutch connector. 6. Disconnect suction hose (1) and discharge hose (2) from compressor.
NOTE: Cap open fitting immediately to keep moisture out of system.
