COMPRESSOR ASSEMBLY
CAUTION:
None of refrigerant, compressor oil and component parts is interchangeable between two types of A / C:
one using CFC-12 (R-12) and the other using HFC-134a (R-134a).
For identification between these two types, refer to page 1B-2.
When replenishing or changing refrigerant and compressor oil and when replacing parts, make sure
that the material or the part to be used is appropriate to the A / C installed in the vehicle being serviced.
Use of incorrect refrigerant or compressor oil will result in leakage of refrigerant, damage in parts or
other faulty condition.
PRECAUTION
When servicing the compressor, keep dirt or foreign material away from getting on or into the compressor parts
and system. Clean tools and a clean work area are important for proper service.
The compressor connection and the outside of the compressor should be cleaned before any ªOn-vehicleº repair
or before removal of the compressor. The parts must be kept clean at all times and any parts to be reassembled
should be cleaned with Trichloroethane, naphtha, kerosene or equivalent solvent and dried with dry air. Use only
lint free cloths to wipe parts.
The operations described are based on bench overhaul with compressor removed from the vehicle, except as
noted. They have been prepared in order of accessibility of the components.
When compressor is removed from the vehicle for servicing, the oil remaining in the compressor should be dis-
carded and new refrigerant oil added to the compressor.
Minor repair procedures may be done on the vehicle without discharging the system. Major repair procedures re-
quire that the system be discharged of refrigerant.
INSPECTION
1) Install manifold gauge set (1) as shown in the figure.
2) Close Hi (4) and Lo (5) hand valves.
3) Run engine at fast idle.
4) Check compressor assembly for following items.
If any of the above checks indicated a defect, repair compressor
assembly.

High pressure gauge reading is not low and low pressure
gauge reading is not higher than normal.

Metallic sound.

Leakage from shaft seal.

HYDRAULIC PRESSURE IN P / S CIRCUIT
HYDRAULIC PRESSURE CHECK
1) After cleaning joint of high pressure hose and P / S pump thor-
oughly, disconnect hose from pump and install special tool (oil
pressure gauge, attachment and hose).
Tighten each flare nut to specified torque.
CAUTION:
Take care not to cause damage to A / C condenser during
service operation, if equipped.
Special Tool
(A): 09915-77410 (Oil pressure gauge)
(B): 09915-77420
2) Check each connection for fluid leakage and bleed air.
Refer to ªAIR BLEEDING PROCEDUREº in this section.
3) With engine idling, turn steering wheel and warm up engine till
temperature of fluid in P/S fluid reservoir rises to 50 ± 60
C (122
± 140
F).
4) Check back pressure by measuring hydraulic pressure with en-
gine idling and hands off steering wheel.
Back pressure: Lower than 1000 kPa (10 kg / cm
2, 142 psi)
When back pressure is higher than specified values, check con-
trol valve and piping for clogging.

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. . . . . . .
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 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.

SECTION 3C1
AIR BAG STEERING WHEEL AND COLUMN
WARNING:

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Please observe all WARNINGS and ªService Precautionsº under ªOn-Vehicle
Serviceº in air bag system section before performing service on or around the air bag system compo-
nents 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.

The procedures in this section must be followed in the order listed to disable the air bag system tem-
porarily and prevent false diagnostic trouble codes from setting. Failure to follow procedures could
result in possible activation of the air bag system, personal injury or otherwise unneeded air bag sys-
tem repairs.
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were re-
moved. If a fastener needs to be replaced, use the correct part number fastener for that application. If
the correct part number fastener is not available, a fastener of equal size and strength (or stronger) may
be used. Fasteners that are not reused, and those requiring thread-locking compound, will be called
out. The correct torque value must be used when installing fasteners that require it. If the above proce-
dures are not followed, parts or system damage could result.

STEERING WHEEL
CAUTION:
Removal of the steering wheel allows the contact coil to turn
freely but do not turn the contact coil (on the combination
switch) more than allowable number of turns (about two and
a half turns from the center position clockwise or counter-
clockwise respectively), or coil will break.
REMOVAL
1) Remove driver air bag (inflator) module from steering wheel re-
ferring to ªDRIVER AIR BAG (INFLATOR) MODULEº earlier in
this section.
2) Remove steering shaft nut.
3) Make alignment marks on steering wheel and shaft for a guide
during reinstallation.
4) Remove steering wheel with special tool.
Special Tool
(A): 09944-36011
CAUTION:
Do not hammer the end of the shaft. Hammering it will
loosen the plastic shear pins which maintain the column
length and impair the collapsible design of the column.
CENTERING CONTACT COIL
1) Check that vehicle's wheels (front tires) are set at straight-ahead
position.
2) Check that ignition switch is at ªLOCKº position.
3) Turn contact coil counterclockwise slowly with a light force till
contact coil will not turn any further.
NOTE:
Contact coil can turn about 5 turns at maximum, that is, if
it is at the center position, can turn about two and a half
turns both clockwise and counterclockwise.
4) From the position where contact coil became unable to turn any
further (it stopped), turn it back clockwise about two and a half
rotations and align center mark with alignment mark.
