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
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).

9) Install special tools (compression gauge) into spark plug
hole.
Special tool
(A) : 09915-64510-001
(B) : 09915-64510-002
(C) : 09915-64530
(D) : 09915-67010
10) Disengage clutch (1) (to lighten starting load on engine) for
M/T vehicle, and depress accelerator pedal (2) all the way to
make throttle fully open.
11) Crank engine with fully charged battery, and read the highest
pressure on compression gauge.
Compression pressure
12) Carry out Steps 9) through 11) on each cylinder to obtain 4
readings.
NOTE:
For measuring compression pressure, crank engine at
least 250 rpm by using fully charged battery.
If measured compression pressure is lower than limit
value, check installation condition of special tool. If it
is properly installed, possibility is compression pres-
sure leakage from where piston ring and valve contact.

VALVE LASH (CLEARANCE)
INSPECTION
1) Remove negative cable at battery.
2) Remove cylinder head cover referring to “CYLINDER HEAD
COVER”.
3) Remove right side engine cover if necessary.
4) Using 17 mm wrench, turn crankshaft pulley (1) clockwise
until cam lobes (2) become perpendicular to shim faces (3)
at valves “1” and “7” as shown in figure.
5) Check valve lashes with thickness gauge (4) according to
the following procedure.
a) Check valve lashes at valves “1” and “7”.
b) Turn camshafts by 90° (by turning crankshaft with wrench).
c) Make sure that cam lobes are perpendicular to shim faces
at valves to be checked (in this case, “3” and “8”), if not,
adjust it by turning crankshaft. Check valve lashes.
d) In the same manner as b) – c), check valve lashes at valves
“4” and “6”.
e) In the same manner as b) – c) again, check valve lashes at
valves “2” and “5”.
Valve clearance specification
If valve lash is out of specification, record valve lash and adjust it
to specification by replacing shim.
REPLACEMENT OF SHIM
1) Close the valve whose shim (2) is to be replaced by turning
crankshaft, then turn tappet (3) till its cut section (1) faces
inside as shown in figure.
2) Lift down the it valve by turning crankshaft to 180°.
3) Hold tappet at that position using special tool as follows.
a) Remove its housing bolts.When cold
(Coolant temperature
is 15 – 25°C
(59 – 77°F))When hot
(Coolant temperature
is 60 – 68°C
