AIR CONDITIONING SYSTEM
PRECAUTION
1. DO NOT HANDLE REFRIGERANT IN AN ENCLOSED
AREA OR NEAR AN OPEN FLAME
2. ALWAYS WEAR EYE PROTECTION
3. BE CAREFUL NOT TO GET LIQUID REFRIGERANT IN
YOUR EYES OR ON YOUR SKIN
If liquid refrigerant gets in your eyes or on your skin.
(a) Wash the area with lots of cool water.
CAUTION:
Do not rub your eyes or skin.
(b) Apply clean petroleum jelly to the skin.
(c) Go immediately to a physician or hospital for professional
treatment.
4. NEVER HEAT CONTAINER OR EXPOSE IT TO NAKED
FLAME
5. BE CAREFUL NOT TO DROP CONTAINER AND NOT
TO APPLY PHYSICAL SHOCKS TO IT
6. DO NOT OPERATE COMPRESSOR WITHOUT
ENOUGH REFRIGERANT IN REFRIGERANT SYSTEM
If there is not enough refrigerant in the refrigerant system oil lu-
brication will be insufficient and compressor burnout may occur,
so take care to avoid this, necessary care should be taken.
7. DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE
WHILE COMPRESSOR IS OPERATING
If the high pressure valves opened, refrigerant flows in the re-
verse direction and could cause the charging cylinder to rup-
ture, so open and close the only low pressure valve.
8. BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH
REFRIGERANT
If refrigerant is overcharged, it causes problems such as insuffi-
cient cooling, poor fuel economy, engine overheating etc.

(a) Remove the pipe from the clamp.
(b) Remove the 4 bolts, then remove the engine moving con-
trol rod and radio setting condenser.
10. REMOVE INTAKE MANIFOLD
(a) Disconnect the fuel pipe No. 1.
(1) Remove the fuel pipe clamp.
(2) Pinch the tube connector, then pull out the fuel pipe
No. 1.
NOTICE:

Check around the quick connector for dirt or mud be-
fore this operation. Remove the dirt if necessary.

Be careful of mud because the quick connector has
an O-ring which seals the pipe and quick connector
that can be contaminated.

Do not use any tools in this operation.

Do not bend or twist the nylon tube. Protect the quick
connector by covering it with a vinyl or plastic bag.

When the pipe and quick connector are stuck, push
and pull the quick connector to release and pull the
quick connector out carefully.
(b) Disconnect the heater inlet water hose.

FUEL SYSTEM (3MZ-FE)
PRECAUTION
1. PRECAUTION
(a) Before working on the fuel system, disconnect the engine wire No. 3 (battery negative terminal) from
battery.
(b) Do not smoke or work near open flame when working on the fuel system.
(c) Keep gasoline away from the rubber or leather parts.
2. DISCHARGE FUEL SYSTEM PRESSURE
CAUTION:

Do not disconnect any parts of the fuel system pres-
sure until you have discharging the fuel system pres-
sure.

Even after discharge the fuel pressure, place a shop
rag over fittings as you separate them in order to re-
duce risk of fuel spray on yourself or in the engine
compartment.
(a) Disconnect the engine wire No. 3 (battery negative termi-
nal).
(b) Remove the circuit opening relay from the engine room
relay block.
(c) Connect the engine wire No. 3 (battery negative terminal).
Torque: 5.4 NVm (55 kgfVcm, 48 in.Vlbf)
(d) Start the engine. After the engine has stopped on its own,
turn the ignition switch OFF.
HINT:
There is a case that DTC P0171 (system to lean) is output.
(e) Check that the engine does not start.
(f) Remove the fuel tank cap, then let the air out of the fuel
tank.
(g) Disconnect battery negative terminal.
(h) Reinstall the circuit opening relay.
3. FUEL SYSTEM
(a) When disconnecting the high fuel pressure line, a large
amount of gasoline will spill out. So observe these proce-
dures.
(1) Work in order to prevent gasoline from spilling out.
(2) Disconnect the fuel pump tube (see page 11-20).
(3) Drain the fuel remaining inside the fuel pump tube.
