9. If the level changes more than 5 mm, the air is badly
bled. So, bleed air again.
Caution
(1) If the fluid level rises suddenly after the engine
is stopped, the bleeding is incomplete.
(2) Incomplete bleeding causes abnormal noises
from the pump and the flow-control valve. This
could lessen the life of the pump and the other
parts.
OIL PUMP PRESSURE TEST
1. Disconnect the pressure hose from the oil pump, and
then connect the special tools.
2. Bleed the air, and then turn the steering wheel several
times while the vehicle is not moving so that the
temperature of the fluid rises to approximately 50 - 60_C.
3. Start the engine and idle it at 1,000±100 r/min.
4. Fully close the shut-off valve of the pressure gauge and
measure the oil pump relief pressure to confirm that it
is within the standard value range.
Standard value: 8.4 - 9.0 MPa
5. If the standard value is not met, the oil pump is defective.
So, replace the oil pump. Then, measure oil pressure
again.
6. With the pressure gauge shut - off valve fully open, check
the hydraulic pressure in unladen condition.
Standard value: 0.2 - 0.8 MPa
7. If the standard value is not met, the oil line or steering
gear is probably defective. So, repair and measure oil
pressure again.
8. Turn the steering wheel fully either left or right and check
the retention hydraulic pressure.
Standard value: 8.4 - 9.0 MPa
9. If the pressure is below the standard value, disassemble
and reassemble the steering gear. If above, replace the
oil pump. Then, measure oil pressure again.
10. Remove the special tools, and tighten the pressure hose
to the specified torque.
Tightening torque: 18±3 N·m
11. Bleed the system.

CHECK
1. Disconnect the pressure hose from the oil pump, and
then connect the special tools.
2. Bleed the air, and then turn the steering wheel several
times while the vehicle is not moving so that the
temperature of the fluid rises to approximately 50 - 60_C.
3. The engine should be idling.
4. Disconnect the connection of the connector for the oil
pressure switch, and set an ohmmeter in position.
5. Gradually close the shut-off valve of the pressure gauge
and increase the hydraulic pressure, then check whether
or not the hydraulic pressure that activates the switch
is the standard value.
Standard value: 1.8 - 2.4 MPa
6. Gradually open the shut-off valve and reduce the hydraulic
pressure; then check whether or not the hydraulic pressure
that deactivates the switch is the standard value.
Standard value: 1.0 - 2.4 MPa
7. Remove the special tools, and then tighten the pressure
hose to the specified torque.
Tightening torque: 18±3 N·m
8. Bleed the system.

DISCHARGING SYSTEM
Use the refrigerant recovery unit to discharge refrigerant gas
from the system.
NOTE : Refer to the Refrigerant Recovery and Recycling
Unit Instruction Manual for operation of the unit.
REFILLING OF OIL IN THE A/C SYSTEM
Too little oil will provide inadequate compressor lubrication
and cause a compressor failure. Too much oil will increase
discharge air temperature.
When a compressor is installed at the factory, it contains
130 cm
3of refrigerant oil. While the A/C system is in operation,
the oil is carried through the entire system by the refrigerant.
Some of this oil will be trapped and retained in various parts
of the system.
When the following system components are changed, it is
necessary to add oil to the system to replace the oil being
removed with the component.
