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).

2) Install special tools (Oil pressure gauge) to vacated threaded
hole.
Special tool
(A) : 09915-77310
(B) : 09915-78211
3) Start engine and warm it up to normal operating tempera-
ture.
4) After warming up, raise engine speed to 4,000 rpm and mea-
sure oil pressure.
Oil pressure specification
: 280 – 430 kPa (2.8 – 4.3 kg/cm
2, 39.8 – 61.1 psi)
at 4,000 rpm
5) Stop engine and remove oil pressure gauge and attachment.
6) Before reinstalling oil pressure switch (2), be sure to wrap its
screw threads with sealing tape (1) and tighten switch to
specified torque.
Tightening torque
Oil pressure switch (a) : 14 N·m (1.4 kg-m, 10.5 lb-ft)
7) Start engine and check oil pressure switch for oil leakage.
If oil leakage is found, repair it.
8) Connect oil pressure switch coupler (1).
NOTE:
Be sure to place transmission gear shift lever in “Neu-
tral” (shift selector lever to “P” range for A/T model), and
set parking brake and block drive wheels.
NOTE:
If sealing tape edge is bulged out from screw threads of
switch, cut it off.

b) Check housing No. and select special tool corresponding to
housing No., referring to “special tool selection table”.
Special tool selection table
c) Hold down the tappet so as not to hang to the shim with
special tool by installing it on camshaft housing with hous-
ing bolt (1) to specified torque.
Special tool
(A) : 09916-67020
Tightening torque
Camshaft housing bolts (for tightening of special tool )
(a) : 8 N·m (0.8 kg-m, 6.0 lb-ft)
4) Turn camshaft by approximately 90° clockwise and remove
shim (3).
5) Using a micrometer (2), measure the thickness of the
removed shim (1), and determine replacement shim by cal-
culating the thickness of new shim with the following formula
and table.
Intake side:
A = B + (C – 0.20 mm (0.008 in.))
Exhaust side:
A = B + (C – 0.30 mm (0.012 in.))
A : Thickness of new shim
B : Thickness of removed shim
C : Measured valve clearance No. on camshaft
housingEmbossed mark

WARNING:
Never put in the hand between cam shaft and tappet.

9) Install camshaft housing (1) and tighten bolts to specified
torque.
Tightening torque
Camshaft housing bolt (a) : 11 N·m (1.1 kg-m, 8.0 lb-ft)
10) Check valve clearance again after adjusting it.
11) After checking and adjusting all valves.
12) Install cylinder head cover, referring to “CYLINDER HEAD
COVER”.

4) Tighten bolts in such order as indicated in figure a little at a
time till they are tightened to specified torque.
Tightening torque
Cylinder head cover bolts (a) : 8 N·m (0.8 kg-m, 6.0 lb-ft)
5) Connect PCV hose (2) to PCV valve (1).
6) Install oil level gauge (3).
7) Install ignition coil assemblies with high-tension cord.
8) Connect ignition coil couplers and clamp harness securely.
9) Install cylinder head upper cover.
10) Install air cleaner assembly, resonator and hoses referring to
“AIR CLEANER ASSEMBLY AND RESONATOR”.
11) Connect negative cable at battery.NOTE:
When installing cylinder head cover, use care so that cyl-
inder head cover gasket or spark plug hole gaskets will
not get out of place or fall off.
