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).

ENGINE LUBRICATION
The oil pump is of a trochoid type, and mounted on the crankshaft. Oil is drawn up through the oil pump strainer
and passed through the pump to the oil filter.
The filtered oil flows into 2 paths in cylinder block.
In one path, oil reaches the crankshaft journal bearings. Oil from the crankshaft journal bearings is supplied to
the connecting rod bearings by means of intersecting passages drilled in the crankshaft, and then injected from
the big end of connecting rod to lubricate piston, rings, and cylinder wall.
In other path oil goes up to the cylinder head and lubricates valves and camshafts, etc., after passing through
the internal oilway of camshafts.
An oil relief valve is provided on the oil pump. This valve starts relieving oil pressure when the pressure exceeds
about 400 kPa (4.0 kg/cm
2, 56.9 psi).

DIAGNOSIS
DIAGNOSIS TABLE
Refer to “ENGINE MECHANICAL DIAGNOSIS TABLE” in Sec-
tion 6.
COMPRESSION CHECK
Check compression pressure on all 4 cylinders as follows:
1) Warm up engine to normal operating temperature.
2) Stop engine after warming up.
3) Remove air cleaner assembly (1), resonator (2) and hoses.
Refer to “AIR CLEANER ASSEMBLY AND RESONATOR”.
4) Remove cylinder head upper cover (1).
5) Disconnect ignition coil couplers (1).
6) Remove ignition coil assemblies (2) with high-tension cord
(3).
7) Remove all spark plugs.
8) Disconnect fuel injector wires (4) at the coupler.NOTE:
After warming up engine, 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.

6A1-6 ENGINE MECHANICAL (M13 ENGINE)
13) After checking, install spark plugs and ignition coil assem-
blies (1) with high-tension cord (2).
14) Connect ignition coil couplers (3).
15) Connect fuel injector wires(4) at the coupler.
16) Check cylinder head upper cover gasket for deterioration
and then install it into groove of cylinder head upper cover
(1) securely.
17) Install cylinder head upper cover with gasket on to cylinder
head cover.
18) Install air cleaner assembly, resonator and hoses referring to
“AIR CLEANER ASSEMBLY AND RESONATOR”.
ENGINE VACUUM CHECK
The engine vacuum that develops in the intake line is a good indi-
cator of the condition of the engine. The vacuum checking proce-
dure is as follows :
1) Warm up engine to normal operating temperature.
2) Stop engine and turn off the all electric switches.
3) Remove cap (1) from intake manifold.
NOTE:
After warming up engine, 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.

ENGINE MECHANICAL (M13 ENGINE) 6A1-7
4) Connect special tool (Vacuum gauge) to intake manifold.
Special tool
(A) : 09915-67310
5) Run engine at specified idle speed and read vacuum gauge.
Vacuum should be within specification.
Vacuum specification (at sea level)
: 59 – 73 kPa (45 – 55 cmHg, 17.7 – 21.6 inHg)
at specified idle speed
6) After checking, disconnect special tool (Vacuum gauge) from
intake manifold.
7) Install cap to intake manifold.
OIL PRESSURE CHECK
Oil level in oil pan
If oil level is low, add oil up to Full level mark (hole) on oil
level gauge.
Oil quality
If oil is discolored, or deteriorated, change it.
For particular oil to be used referring to the table in Section
0B.
Oil leaks
If leak is found, repair it.
1) Disconnect oil pressure switch coupler (1) and remove oil
pressure switch (2) from cylinder block.
NOTE:
Prior to checking oil pressure, check the following items.
1. Full level mark (hole)
2. Low level mark (hole)

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.
