INSTALLATION
NOTE:

All parts to be installed must be perfectly clean.

Be sure to oil crankshaft journals, journal bearings, thrust
bearings, crankpins, connecting rod bearings, pistons, pis-
ton rings and cylinder bores.

Journal bearings, bearing caps, connecting rods, rod bear-
ings, rod bearing caps, pistons and piston rings are in com-
bination sets. Do not disturb combination and try to see that
each part goes back to where it came from, when installing.
1) Fit main bearings to cylinder block (1).
Among two halves of main bearing, one halt has oil groove (3).
Install this half with oil groove to cylinder block, and another half
without oil groove to bearing cap.
Make sure that two halves are painted in the same color.
2) Fit thrust bearings (1) to cylinder block between No.2 and No.3
cylinders. Face oil groove (2) sides to crank webs.
3) Put crankshaft on cylinder block.
4) Fit bearing caps sequentially in ascending order, 1, 2, 3 and 4,
starting from pulley side. Be sure to point arrow mark (2) (on
each cap) to crankshaft pulley side (1).
Gradual and uniform tightening is important for bearing cap
bolts. Make sure that four caps become tight equally and pro-
gressively till specified torque is attained.
Tightening Torque
(a): 53 N
.m (5.3 kg-m, 38.5 lb-ft)
NOTE:
After tightening cap bolts, check to be sure that crankshaft
rotates smoothly when turned by hand.

5) Install oil seal housing and its gasket.
Install new gasket. Do not reuse gasket removed in disassem-
bly. Oil lip portion of oil seal before installing. Tighten housing
bolts to specification.
After installing oil seal housing, gasket edges might bulge out;
if so, cut them off to make them flush with cylinder block and
oil seal housing.
Tightening Torque
(b): 12 N
.m (1.2 kg-m, 9.0 lb-ft)
6) Install oil pump.
Refer to item “Oil pump” for installation of oil pump.
7) Install flywheel (M / T model) or drive plate (A / T model).
Using special tool, lock flywheel and torque its bolts (1) to spec-
ification.
Special Tool
(A): 09924-17810
Tightening Torque
(c): 78 N
.m (7.8 kg-m, 56.5 lb-ft)
8) Install pistons and connecting rods as previously outlined.
9) Install oil pump strainer and oil pan.
10) Install cylinder head assembly to cylinder block (1).
Before installing cylinder head assembly to cylinder block,
install check valve (2) into oil gallery in cylinder block, directing
slit of valve toward top of cylinder block.
NOTE:
Tighten cylinder head bolts to specified torque as pre-
viously outlined.
Whenever installing cylinder head to new cylinder block,
use following procedure to tighten cylinder head bolts.

Tighten cylinder head bolts to specified torque as pre-
viously outlined and loosen them once till tightening
torque becomes “zero”. And then torque them to specifi-
cation again.
11) Install crankshaft timing belt pulley, timing belt, crankshaft
pulley, water pump pulley, etc., as previously outlined.
12) Install clutch to flywheel (M / T model).
For clutch installation, refer to Section 7C.
13) Install engine with transmission to body as previously outlined.

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).

Check compression pressure on all four cylinders as follows:
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).
5) Install special tools (Compression gauge) into spark plug hole.

OIL PRESSURE CHECK
NOTE:
Prior to checking oil pressure, check the following items.

Oil level in oil pan.
If oil level is low, add oil up to Full level mark on oil level
gauge.

Oil quality.
If oil is discolored, or deteriorated, change it.
For particular oil to be used, refer to the table in Section 0B.

Oil leaks.
If leak is found, repair it.
1) Remove oil pressure switch (1) from cylinder block.
2) Install special tool (Oil pressure gauge) to vacated threaded
hole.
Special Tool
(A): 09915-77311
3) Start engine and warm it up to normal operating temperature.
NOTE:
Be sure to place transmission gear shift lever in “Neutral”
(shift selector lever to “P” range for A / T model), and set
parking brake and block drive wheels.
4) After warming up, raise engine speed to 4,000 r / min and mea-
sure oil pressure.
Oil pressure specification:
360 – 440 kPa (3.6 – 4.4 kg / cm
2, 51.2 – 62.6 psi) at 4,000 r / min
(rpm)
5) Stop engine and remove oil pressure gauge.

6) Before reinstalling oil pressure switch (1), be sure to wrap its
screw threads with sealing tape (2) and tighten switch to speci-
fied torque.
NOTE:
If sealing tape edge is bulged out from screw threads of
switch, cut it off.

CYLINDER HEAD COVER
REMOVAL
1) Disconnect negative cable at battery.
2) Disconnect breather hose (2) and PCV valve (3) from head cov-
er.
3) Disconnect ignition coil couplers (6).
4) Remove ignition coil assemblies (5) with high-tension cord (4).
5) Remove cylinder head cover (1) with cylinder head cover gasket
and O-rings.
INSTALLATION
1) Install O-rings (3) and cylinder head cover gasket (2) to cylinder
head cover (1).
NOTE:
Be sure to check each of these parts for deterioration or any
damage before installation and replace if found defective.
2) Install cylinder head cover to cylinder head and tighten cover
bolts to specified torque.
Tightening Torque
(a): 11 N
.m (1.1 kg-m, 8.0 lb-ft)
NOTE:
When installing cylinder head cover, use care so that cylin-
der head cover gasket or O-rings will not get out of place or
fall off.
3) Install ignition coil assemblies (5) with high-tension cord (4).
4) Connect ignition coil couplers (6).
5) Connect breather hose (2) and PCV valve (3) to head cover (1).
6) Connect negative cable at battery.

4. Damper

2) Install tensioner (2) and tensioner plate (3):
Do not tighten tensioner bolt (1) with wrench yet. Hand tighten
only at this time.
Check to ensure that plate movement in arrow direction as
shown in figure causes tensioner to move in the same direction.
If no associated movement between plate and tensioner occurs,
remove tensioner and plate again and reinsert plate lug into ten-
sioner hole.
3) Check that timing mark (2) on camshaft timing belt pulley is
aligned with “V” mark (1) on cylinder head cover. If not, align two
marks by turning camshaft but be careful not to turn it more than
its allowable turning range which is described on previous page.
4) Check that timing mark (2) on crankshaft timing belt pulley is
aligned with arrow mark (1) on oil pump case. If not, align two
marks by turning crankshaft but be careful not to turn it more
than its allowable turning range which is described on previous
page.
5) Install timing belt and tensioner spring (2).
With two sets of marks aligned and tensioner plate pushed up,
install timing belt on two pulleys in such a way that drive side (1)
of belt is free from any slack.
And then install tensioner spring as shown in figure, and hand-
tighten tensioner stud (3).
NOTE:

When installing timing belt, match arrow mark (
) on
timing belt with rotating direction of crankshaft.

In this state, No. 4 piston is at top dead center of compres-
sion stroke.
