WARNING:
For vehicles equipped with Supplement 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 “Air Bag System Components and Wiring Location View” under “Gener-
al Description” 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 “Service Precau-
tions” 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 or 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).

1) Warm up engine.
2) Stop engine after warming up.
NOTE:
After warming up engine, place transmission gear shift le-
ver in “Neutral” (shift selector lever to “P” range for A / T
model), and set parking brake and block drive wheels.
3) Remove ignition coil assemblies (1) and all spark plugs (2) refer-
ring to Section 6F.
WARNING:
Failure in disconnecting couplers from ignition coil as-
semblies can cause spark to occur in engine room possi-
bly resulting in a dangerous explosion.
4) Disconnect fuel injector wire harness at couplers (2).

ENGINE VACUUM CHECK
The engine vacuum that develops in the intake line is a good indica-
tor of the condition of the engine. The vacuum checking procedure
is as follows:
1) Warm up engine to normal operating temperature.
NOTE:
After warming up engine, place transmission gear shift le-
ver in “Neutral” (shift selector lever to “P” range for A / T
model), and set parking brake and block drive wheels.
2) With engine stopped, disconnect EVAP canister purge valve
hose from intake manifold and connect 3-way joint, hoses and
special tools (vacuum gauge and joint) between intake manifold
and vacuum hose disconnected.

(C): Hose 09343-03087
(D): 3-way joint 09367-04002
3) Run engine at specified idle speed, and read vacuum gauge.
Vacuum should be within the following specification.
Vacuum specification (at sea level):
52.6 – 65.8 kPa (40 – 50 cm
Hg, 15.7 – 19.7 in.Hg) at specified
idling speed
4) After checking, connect vacuum hose to intake surge tank.

6A1-50 ENGINE MECHANICAL (G13B, 1-CAM 16-VALVES ENGINE)
ASSEMBLY
1) Before installing valve guide into cylinder head, ream guide hole
with special tool (11 mm reamer) to remove burrs and make it
truly round.
Special Tool
(A): 09916-34542
(B): 09916-38210
2) Install valve guide to cylinder head.
Heat cylinder head uniformly at a temperature of 80 to 100C
(176 to 212F) so that head will not be distorted, and drive new
valve guide into hole with special tools. Drive in new valve guide
until special tool (Valve guide installer) contacts cylinder head.
After installing, make sure that valve guide protrudes by 11.5
mm (0.45 in.) from cylinder head.
Special Tool
(C): 09916-56011
(D): 09916-58210
NOTE:

Do not reuse valve guide once disassembled.
Install new valve guide (Oversize).

Intake and exhaust valve guides are identical.
Valve guide oversize: 0.03 mm (0.0012 in.)
Valve guide protrusion (In and Ex): 11.5 mm (0.45 in.)
3) Ream valve guide bore with special tool (5.5 mm reamer). After
reaming, clean bore.
Special Tool
(A): 09916-34542
(B): 09916-34550
4) Install valve spring seat to cylinder head.

A: Valve spring retainer side
B: Valve spring seat side

5) Install new valve stem seal (1) to valve guide.
After applying engine oil to seal and spindle of special tool (Valve
guide installer handle), fit oil seal to spindle, and then install seal
to valve guide by pushing special tool by hand.
After installing, check to be sure that seal is properly fixed to
valve guide.
Special Tool
(A): 09917-98221
(B): 09916-58210
NOTE:

Do not reuse seal once disassembled. Be sure to install
new seal.

When installing, never tap or hit special tool with a ham-
mer or else. Install seal to guide only by pushing special
tool by hand. Tapping or hitting special tool may cause
damage to seal.
6) Install valve to valve guide.
Before installing valve to valve guide, apply engine oil to stem
seal, valve guide bore, and valve stem.
7) Install valve spring and spring retainer.
Each valve spring has top end (large-pitch (1) end) and bottom
end (small-pitch (2) end). Be sure to position spring in place with
its bottom end (small-pitch end) facing the bottom (valve spring
seat side).
8) Using special tools (Valve lifter), compress valve spring and fit
two valve cotters (1) into groove in valve stem.

SPECIAL TOOLS

1. Cooling fan motor

ENGINE COOLING 6B-3
THERMOSTAT
A wax pellet type thermostat is used in the coolant outlet passage
to control the flow of engine coolant, to provide fast engine warm
up and to regulate coolant temperatures.
A wax pellet element is hermetically contained in a metal case, and
expands when heated and contracts when cooled.
When the pellet is heated and expands, the metal case pushes
down the valve to open it.
As the pellet is cooled, the contraction allows the spring to close the
valve.
Thus, the valve remains closed while the coolant is cold, preventing
circulation of coolant through the radiator.
At this point, coolant is allowed to circulate only throughout the en-
gine to warm it quickly and evenly.
As the engine warms, the pellet expands and the thermostat valve
opens, permitting coolant to flow through the radiator.
In the top portion of the thermostat, an air bleed valve (1) is pro-
vided; this valve is for venting out the gas or air, if any, that is accu-
mulated in the circuit.

COOLING FAN
The cooling fan is driven by electric motor, and the motor is acti-
vated by ECM / PCM (engine coolant temp.). For its details, refer to
Section 6E.
WARNING:
Keep hands, tools, and clothing away from engine cooling
fan to help prevent personal injury. This fan is electric and
can come on whether or not the engine is running. The fan
can start automatically in response to the ECM / PCM (en-
gine coolant temp.) with the ignition switch in the “ON”
position.
