1999 SUZUKI GRAND VITARA torque

0A-4 GENERAL INFORMATION
WARNING:
SDM
 During service procedures, be very careful when handling a Sensing and Diagnostic Module (SDM).
Never strike or jar the SDM.
Never power up the air bag system when the SDM is not rigidly attached to the vehicle. All SDM and
mounting bracket fasteners must be carefully torqued and the arrow must be pointing toward the
front of the vehicle to ensure proper operation of the air bag system.
The SDM could be activated when powered while not rigidly attached to the vehicle which could
cause deployment and result in personal injury.
WARNING:
Driver and Passenger Seat Belt Pretensioners
 For handling and storage of a live seat belt preten-
sioner, select a place where the ambient temperature
below 65°C (150°F), without high humidity and away
from electric noise.
 Never carry seat belt pretensioner by wire or connec-
tor of pretensioner. When placing a live seat belt pre-
tensioner on the workbench or some place like that, be
sure not to lay it with its exhaust hole (1) provided side
facing down. It is also prohibited to put something on
its face with an exhaust hole or to put a seat belt pre-
tensioner on top of another. Otherwise, personal injury
may result.
 Never dispose of live (inactivated) seat belt pretension-
ers (drive and passenger). If disposal is necessary, be
sure to activate them according to activation proce-
dures described in SECTION 10B before disposal.
 The seat belt pretensioner immediately after activation
is very hot. Wait for at least half an hour to cool it off
before proceeding the work.
 With many service procedures, gloves and safety
glasses should be worn to prevent any possible irrita-
tion of the skin or eyes.

MAINTENANCE AND LUBRICATION 0B-7
1) Drain engine oil by removing drain plug.
2) After draining oil, wipe drain plug clean. Reinstall drain plug,
and tighten it securely as specified below.
Tightening torque
Engine oil drain plug (a) :
50 N·m (5.0 kg-m, 36.5 lb-ft)
3) Loosen oil filter by using oil filter wrench (special tool).
Special tool
(A) : 09915-47310
4) Screw new filter on oil filter stand by hand until the filter O-
ring contacts the mounting surface.
5) Tighten the filter 3/4 turn from the point of contact with the
mounting surface using an oil filter wrench.
Tightening torque
(For reference)
Oil filter (b) : 14 N·m (1.4 kg-m, 10.5 lb-ft)
NOTE:
Before fitting new oil filter, be sure to oil its O-ring. Use
engine oil for this purpose.
CAUTION:
To tighten oil filter properly, it is important to accurately
identify the position at which filter O-ring first contacts
the mounting surface.

Never use heat for bending pipes. When bending a pipe, try to make its bending radius as slight as possible.
Keep internal parts of air conditioning free from moisture and dirt. When disconnecting any line from system,
install a blind plug or cap to the fitting immediately.
When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.
Tighten flared nuts to specified torque.
Tightening torque
8 mm (0.31 in.) pipe : 13 N·m (1.3 kg-m, 9.5 lb-ft)
12.7 mm (0.5 in.) pipe : 22 N·m (2.2 kg-m, 16.0 lb-ft)
16 mm (0.63 in.) pipe : 33 N·m (3.3 kg-m, 24.0 lb-ft)
Route drain hose so that drained water does not make any contact to vehicle components.
Handling refrigerant HFC-134a (R-134a)
When handling refrigerant, always wear goggles to protect your eyes.
Avoid you direct contact to liquid refrigerant.
Do not heat refrigerant container higher than 40 °C (104 °F).
Do not discharge refrigerant into atmosphere.
Do not allow liquid refrigerant to touch bright metals. Refrigerant combined with moisture is corrosive and
will tarnish surfaces of bright metals including chrome.
After recovering refrigerant from system, the amount of compressor oil removed must be measured and the
same amount added to the system.
Refrigerant recovery
When discharging refrigerant out of A/C system, always recover it by using refrigerant recovery and recycling
equipment. Discharging refrigerant HFC-134a (R-134a) into atmosphere would cause adverse effect to environ-
ments.
Refrigerant charge
Charge a proper amount of refrigerant to A/C system according to charging procedure described in recovery,
evacuation and charging.NOTE:
When handling recovery and recycling equipment, be sure to follow the instruction manual for the
equipment.
CAUTION:
Do not perform an additional refrigerant charging to A/C system. This cause it to overcharge.

4) Install magnet clutch (1).
a) Set magnet clutch squarely over clutch installation boss.
b) Place special tool onto clutch bearing.
Ensure that edge rests only on inner race of bearing.
Special tool

c) Install new circlip.
5) Adjust clearance between armature plate (1) and magnet
clutch (2) by putting shim(s) on compressor shaft.
Standard clearance between armature plate and magnet
clutch “a” :
0.35 - 0.6 mm (0.014 - 0.023 in.)
6) Tighten new armature plate nut (1) to specified torque.

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
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” 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
“LOCK” 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:
For the descriptions (items) not found in this section, refer to the same section of the Service Man-
ual mentioned in the FOREWORD of this manual.
Some parts in the Power Steering Gear Box cannot be disassembled or adjusted. For detailed infor-
mation, refer to the description of “POWER STEERING GEAR BOX ASSEMBLY”.
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 replacement part of lesser quality or substitute design. Torque values must be used as speci-
fied during reassembly to assure proper retention of these parts.
