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).

6A1-76 ENGINE MECHANICAL (M13 ENGINE)
Use a dial gauge to read displacement in axial (thrust) direction of
crankshaft.
If its limit is exceeded, replace thrust bearing with new standard
one or oversize one to obtain standard thrust play.
Crankshaft thrust play
Standard : 0.11 – 0.31 mm (0.0043 – 0.0122 in.)
Limit : 0.35 mm (0.0138 in.)
Out-of-round and taper (uneven wear) of journals
An unevenly worn crankshaft journal shows up as a difference in
diameter at a cross section or along its length (or both). This dif-
ference, if any, is determined by taking micrometer readings. If
any one of journals is badly damaged or if amount of uneven wear
in the sense explained above exceeds its limit, regrind or replace
crankshaft.
Crankshaft out-of-round and taper
Limit : 0.01 mm (0.0004 in.)
Out-of-round : A – B
Taper : a – b
Main Bearings
General information
Service main bearings are available in standard size and
0.25 mm (0.0098 in.) undersize, and each of them has 5
kinds of bearings differing in tolerance.
Upper half of bearing (1) has an oil groove (2) as shown in
figure.
Install this half with oil groove to cylinder block.
Lower half of bearing does not have an oil groove.
Visual inspection
Check bearings for pitting, scratches, wear or damage.
If any malcondition is found, replace both upper and lower halves.
Never replace either half without replacing the other half.
Main bearing clearance
Check clearance by using gaging plastic according to the follow-
ing procedure.
1) Remove bearing caps.
2) Clean bearings and main journals.

9) Install flywheel (drive plate for A/T).
Using special tool, lock flywheel or drive plate, and tighten
flywheel or drive plate bolts applied with sealant to specifica-
tion.
“A” : Sealant 99000-31110
Special tool
(A) : 09924-17810
Tightening torque
Flywheel or drive plate bolts
(a) : 70 N·m (7.0 kg-m, 51.0 lb-ft)
10) Install the following parts to engine as previously outlined.
Piston and connecting rod
Cylinder head assembly
Camshaft, tappet and shim
Timing chain guide, chain tensioner adjuster, chain ten-
sioner, timing chain and crankshaft timing sprocket
Timing chain cover
Cylinder head cover

ENGINE COOLING SYSTEM INSPECTION
AND SERVICE
1) Check cooling system for leakage or damage.
2) Wash radiator cap and filler neck with clean water by remov-
ing radiator cap when engine is cold.
3) Check coolant for proper level and freeze protection.
4) Using a pressure tester (1), check system and radiator cap
(2) for proper pressure holding capacity.
If replacement of cap is required, use a proper cap for this
vehicle.
Cooling system and radiator cap holding pressure (for
inspection)
: 110 kPa (1.1 kg/cm
2, 15.6 psi)
5) Tighten hose clamps and inspect all hoses. Replace hoses
whenever cracked, swollen or otherwise deteriorated.
6) Clean frontal area of radiator core.
COOLING SYSTEM FLUSH AND REFILL
1) Remove radiator cap when engine is cool.
a) Turn cap counterclockwise slowly until it reaches a “stop”.
(Do not press down while turning it).
b) Wait until pressure is relieved (indicated by a hissing
sound) then press down on cap and continue to turn it
counterclockwise.
2) With radiator cap removed, run engine until upper radiator
hose is hot (this shows that thermostat is open and coolant is
flowing through system). WARNING:
To help avoid danger of being burned, do not remove
radiator cap while engine and radiator are still hot.
Scalding fluid and steam can be blown out under pres-
sure if cap is taken off too soon.
NOTE:
After installing radiator cap to radiator, make sure that
the ear of cap lines is parallel to radiator.
WARNING:
To help avoid danger of being burned, do not remove
radiator cap while engine and radiator are still hot.
Scalding fluid and steam can be blown out under pres-
sure if cap is taken off too soon.
