Service.)
(3) Start the engine and let it idle.
(4) Loosen the bleeder screw on the left side of the control
valve and set the special tool to the bleeder screw.
(5) Turn the steering wheel all the way to the left, immediately
returning it half way back.
At this time confirm that air is discharged with the fluid.
(6) Repeat step (5) two or three times to make sure that
there is no more air in the system. Tighten the bleeder
screw and remove the special tool.
(7) Repeat steps (4) through (6) for the right side bleeder
screw, turning the steering wheel to the right this time.
(8) Loosen the power cylinder bleeder screw and set the
special tool to the bleeder screw.
Caution
Loosen the bleeder screw about 30 to 45 degrees,
and secure it with the special tool (rotation prevention
metal fixtures) so as not to be loosened more.
(9) Start the engine and keep the front wheels in a straight
ahead position. Increase the engine speed once to a
speedometer reading of 70-80 km/h (43-50 mph) to
operate the oil pump for the rear wheels.
Caution
Pay particular attention to all four wheels that rotate.
NOTE
When the engine speed is increased, the fluid circulates
through the oil pump but it does not circulate through
the tube (special tool).
(lO)With a 30-40 km/h (19-25 mph) speedometer reading
maintained, turn the steering wheel all the way clockwise
and counterclockwise to ensure that pressure rises, caus-
ing air to circulates through the tube (special tool) and
to be discharged from the reserve tank.
(11) Repeat step (10) several times to make sure that there
is no more air in the system. Tighten the bleeder screw
and remove the special tool.
that the difference in the fluid levels when the
engine is running and when it is stopped are within 5
mm
in.).
If the difference exceeds 5 mm in.), there is still
air in the system and it must be bled again.
Caution
If air has not been completely bled from the system,
the pump will make a humming sound or an unusual
noise will come from the flow control valve; this also
contributes to shortened pump life.
