A: SPECIFICATION
B: INSPECTION
1) Check the power steering fluid for deterioration
or contamination. If the fluid is highly deteriorated
or contaminated, drain it and refill with new fluid.
2) Check the joints and units for oil leakage. If any
oil leaks are found, repair or replace the applicable
part.
3) Inspect the fluid level of reservoir tank with vehi-
cle on level surface and engine stopped.
If the level is at “MIN.” point or below, add fluid to
keep the level in the specified range of the indica-
tor. If at “MAX.” point or above, drain fluid by using
a syringe or the like.
(1) Check at power steering fluid temperature
20°C (68°F); read the fluid level on the “COLD”
side.
(2) Check at power steering fluid temperature
80°C (176°F); read the fluid level on the “HOT”
side.
C: REPLACEMENT
1) Lift-up the vehicle.
2) Remove the crossmember support.
3) Remove the pipe joint in the center of gearbox,
and connect the vinyl hose to the pipe and joint.
Wipe fluid off while turning the steering wheel.
4) Add the specified fluid to reservoir tank at “MAX”
level.
5) Maintaining the fluid level of Step 4), continue to
turn the steering wheel slowly from lock to lock until
the bubbles stop appearing on oil surface.
6) If the steering wheel is turned in a low fluid level
condition, air will be sucked into the pipe. If air has
entered, leave it for about half an hour and then re-
peat step 5) again.
7) Start the engine and let it idle.
8) Continue to turn the steering wheel slowly from
lock to lock again until the bubbles stop appearing
on oil surface, while keeping the fluid at the level in
Step 4).
Normally bubbles will stop appearing after turning
the steering wheel from lock to lock three times.
9) In case bubbles do not stop appearing in the
tank, leave it for about half an hour and then repeat
step 4) again.
10) Lower the vehicle, and then idle the engine.
11) Continue to turn the steering wheel from lock to
lock until the bubbles stop appearing and change of
the fluid level is within 3 mm (0.12 in).
12) In case the following happens, leave it about
half an hour and then do step 8) to 11) again.
(1) The fluid level changes over 3 mm (0.12 in).
(2) Bubbles remain on the upper surface of the
fluid.
(3) Grinding noise is generated from oil pump.
13) Check the fluid leakage after turning steering
wheel from lock to lock with engine running.
