2) With engine stopped, check fluid level indicated on fluid tank,
which should be between MAX and MIN marks. If it is lower than
MIN, fill fluid up to MAX mark.
NOTE:

Be sure to use an equivalent of DEXRON

-II or DEX-
RON

-III for P / S fluid.

Fluid level should be checked when fluid is cool.

POWER STEERING (P/S) SYSTEM
WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:

Some parts in the Power Steering Gear Box cannot be disassembled or adjusted. For detailed informa-
tion, refer to the description of ªPOWER STEERING GEAR BOX ASSEMBLYº.

All steering gear fasteners are important attaching parts in that they could affect the performance of vital
parts and systems, and / or could result in major repair expense. They must be replaced with one of the
same part number or with an equivalent part if replacement becomes necessary. Do not use a replace-
ment part of lesser quality or substitute design. Torque values must be used as specified during reas-
sembly to assure proper retention of these parts.

Although the figures in this section show only the left-hand steering vehicle, the same work procedure
and data apply to the right-hand steering vehicle.

5) Check relief pressure

Increase engine speed to about 1,500 r / min (rpm). Close
gauge valve gradually while watching pressure increase indi-
cated by gauge and take reading of relief pressure (maximum
hydraulic pressure).
Relief pressure:
6200 ± 7000 kPa
(62 ± 70 kg / cm
2, 882 ± 995 psi) G16 Type engine. . . . . . .
6700 ± 7500 kPa
(67 ± 75 kg / cm
2, 953 ± 1067 psi) J20 Type engine. . . . . . .
7050 ± 7850 kPa
(70.5 ± 78.5 kg / cm
2, 1003 ± 1116 psi) H25 Type engine. .

When it is higher than specified values, possible cause is mal-
function of relief valve.

When it is lower than specified values, possible cause is either
failure of P / S pump or settling of relief valve spring.
CAUTION:
Be sure not to close gauge valve for longer than 10 se-
conds.

Next, open gauge valve fully and increase engine speed to
about 1,500 r / min (rpm). Then turn steering wheel to the left
or right fully and take reading of relief pressure.
Relief pressure:
6200 ± 7000 kPa
(62 ± 70 kg / cm
2, 882 ± 995 psi) G16 Type engine. . . . . . .

(70.5 ± 78.5 kg / cm
2, 1003 ± 1116 psi) H25 Type engine. .

When it is higher than specified values, possible cause is mal-
function of relief valve.

When it is lower than specified values, possible cause is failure
in steering gear box. Replace gear box.
CAUTION:
Be sure not to hold steering wheel at fully turned posi-
tion for longer than 10 seconds.
BOOT
STEERING RACK BOOT CHECK
Check boot for crack and damage which, if any, means possibility
of rusty gear, entry of dust or lack of grease. Also, check if any of
such faulty conditions exists.
Check steering rack boot for dent or breakage.
If there is a dent, keep boot in most compressed state for some se-
conds to correct dent.

TIE-ROD END BOOT CHECK
Check boot for crack and damage and if any, replace it with a new
one.
AIR BLEEDING PROCEDURE
1) Hoist the front end of vehicle and apply safety stands.
2) Fill P / S fluid reservoir with fluid up to specified level.
NOTE:
Before starting engine, place transmission gear shift lever
in ªNeutralº (shift selector lever to ªPº range for A / T mod-
el), and set parking brake.
3) After running engine at idling speed for 3 to 5 seconds, stop it
and add fluid to satisfy specification.
4) With engine stopped, turn steering wheel to the right and left as
far as it stops, repeat it a few times and fill fluid to specified level.
5) With engine running at idling speed, repeat stop-to-stop turn of
steering wheel till all foams in P / S fluid reservoir are gone.
NOTE:
Make sure to bleed air completely. If air remains in fluid, P / S
pump may make humming noise or steering wheel may feel
heavy.
6) Finally check to make sure that fluid is filled to specified level.

REMOVAL
CAUTION:
Never disassemble tie-rod except for canvas top LH model.
Performing this prohibited service will affect original per-
formance.
1) Remove steering gear box by referring to ªPOWER STEERING
GEAR BOX ASSEMBLY REMOVALº in this section.

end lock nut position of tie-rod end thread.
3) Loosen tie-rod end lock nut and remove tie-rod end.
4) Remove boot wire and clip.
5) Remove boot from tie-rod.
INSTALLATION
1) Visually inspect that rack and rack end ball joint are free from dirt
or foreign matters. Clean thoroughly with cloth or such.
Position boot properly in grooves of gear case and tie-rod and
clamp it with wire and clip.
Wire should be new and should go around twice.
Pull its both ends together by screw driver or such and make
sure that the wire won't be crossed. Then twist the ends several
times, the twisted ends should be bent in the circumferential
direction.
After this, check to ensure that wire is tight and boot is free from
twist and dent.
