POWER STEERING SYSTEM -Checking
Fluid Level Check
Check the fluid level when the fluid IS cold.
Refer to MA section
Power Steering Pump
Belt Tension
Refer to MA section
Fluid Leakage Check
1 Run engine at idle speed or 1,000 rpm
Make sure temperature of fluid
in tank rises to
60 to 80°C (140 to 176°F).
2 Turn steering wheel to right-to-left several
times
3 Hold steering wheel at each "lock" position for
five seconds
and carefully check for fluid
leakage
CAUTION :
0 Do not hold steering wheel at "lock" position
for more than 15 seconds at a time.
0 If fluid leaks at connectors, replace O-ring (if
equipped) Do not overtighten connector as
this can damage O-ring and connector.
- Bleeding Hydraulic System -
1. Raise front end of vehicle until wheels clear
ground
2 While adding fluid, quickly turn steering wheel
fully to right and
left and lightly touch steering
stoppers.
Repeat steering wheel operation until fluid
level no
longer decreases
Repeat step 2 above
3. Start engine.
Hydraulic System Check
Before starting, check belt tension, driving pulley
and tire pressure. (Refer to MA section )
1 Set Tool Open shut off valve Then bled air

2 Run engine.
Make sure temperature of fluid in tank rises to
60 to 80°C
(140 to 176°F).
3 Check pressure with steering wheel fully turned
in left and right
CAUTION:
Do not hold steering wheel at lock position for
more than fifteen seconds.
Standard pressure:
6,669 - 7,257 kPa
(68
- 74 kglcm' ,967 - 1,052 psi at idling)

0
If oil pressure is below the standard, slowly
close shut-off valve and check pressure
If pressure raises to standard, gear is damaged
If pressure remains below standard, pump
IS
damaged.
Gear may be damaged
If oil pressure is above the standard, pump may
be damaged 5
CAUTION:
Do not close shutoff valve for more than fifteen
seconds.
6 After checking hydraulic system, remove Tool
and add fluid as necessary, then completely
bleed
air out of system
