(B): 09915-78211
NOTE:
At this time, be very careful not to exert force to where
heated oxygen sensor and its lead wire are connected.
4) Reinstall oil filter.
5) Start engine and warm it up to normal operating temperature.
6) After warming up, raise engine speed to 4,000 r / min and mea-
sure oil pressure.
Oil pressure specifications: 270 – 370 kPa

38.4 – 52.6 psi) at
4,000 r / min (rpm)
7) After checking oil pressure, stop engine and remove oil filter
and oil pressure gauge.
8) Before reinstalling oil pressure switch (1), be sure to wrap its
screw threads with a sealing tape and tighten switch to speci-
fied torque.
NOTE:
If sealing tape edge is bulged out from screw threads of
switch, cut it off.

9) After oiling oil filter “O” ring (rubber gasket), screw oil filter on
oil filter stand by hand until filter “O” ring contacts mounting sur-
face.
CAUTION:
To tighten oil filter properly, it is important to accurately
identify the position where filter “O” ring first contacts
mounting surface.
10) Tighten filter (1) 3 / 4 (270) turn from the point of contact with
mounting surface using an oil filter wrench.

but do not overtighten it.
11) After installing oil filter, start engine and check oil filter for oil
leakage.

6A-20 ENGINE MECHANICAL (G10, 1-CAM 6-VALVES ENGINE)
CAUTION:

Don’t turn camshaft or start engine (i.e., valves should not be operated) for about half an hour after
reinstalling hydraulic valve lash adjusters and camshaft. As it takes time for valves to settle in place,
operating engine within half an hour after their installation may cause interference to occur between
valves and piston.

If air is trapped in valve lash adjuster, valve may make tapping sound when engine is operated after
valve lash adjuster is installed. In such a case, run engine for about half an hour at about 2,000 – 3,000
r / min., and then air will be purged and tapping sound will cease. Should tapping should not cease,
it is possible that valve lash adjuster is defective. Replace it if defective.
If defective adjuster can’t be located by hearing among 6 of them, check as follows.
1) Stop engine and remove cylinder head cover.
2) Push adjuster downward by hand (with less than 15 kg or 33 lbs force) when cam crest is not on
adjuster to be checked and check if clearance exists between cam and adjuster. If it does, adjuster
is defective and needs replacement.
VALVE LASH ADJUSTER NOISE DIAGNOSIS
In case of the followings, valve lash adjuster noise may be caused by air trapped into valve lash adjusters.

Vehicle is left for 24 hours or more.

Engine oil is changed.

Hydraulic lash adjuster is replaced or reinstalled.

Engine is overhauled.
If noise from valve lash adjusters is suspected, perform the following checks.
1) Check engine oil for the followings.

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

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

Oil leaks
If leak is found, repair it.

Oil pressure (refer to Oil Pressure Check in this section)
If defective pressure is found, repair it.
2) Run engine for about half an hour at about 2,000 to 3,000 r / min., and then air will be purge and tapping sound
will cease.
3) Should tapping sound not cease, it is possible that hydraulic valve lash adjuster is defective.
Replace it if defective.
If defective adjuster can’t be located by hearing among 16 of them, check as follows.
a) Stop engine and remove cylinder head cover.
b) Push adjuster downward by hand (with less than 20 kg or 44 lbs. Force) when cam crest is not on adjuster
to be check if clearance exists between cam and adjuster.
If it does, adjuster is defective and needs replacement.

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.

ON-VEHICLE INSPECTION
1) With battery negative cable disconnected, disconnect injector
coupler.
2) Connect ohmmeter to each injector terminal and measure resis-
tance.

3) Connect injector coupler.
4) Remove air cleaner assembly without disconnecting IAT sensor
coupler.
5) Check that fuel is injected out in conical shape from fuel injector
when cranking or running engine.
If no fuel is injected, check wiring harness for continuity and cou-
plers for proper connection referring to “DIAGNOSTIC FLOW
TABLE B-1”.
If fuel is not injected out in conical shape, replace injector.

EVAP CANISTER PURGE INSPECTION
NOTE:
Before inspection, check to make sure that gear shift lever is
in neutral position (with A / T model, selector lever in “P” range)
and that parking brake lever is pulled all the way up.
1) Disconnect purge hose from EVAP canister.
2) Place finger against the end of disconnected hose and check
that vacuum is not felt there when engine is cool and running at
idle speed.
3) Connect purge hose to EVAP canister and warm up engine to
normal operating temperature.
4) Disconnect purge hose from EVAP canister.
5) Also check that vacuum is felt when engine is running at idle
speed.
NOTE:
The EVAP canister purge system does not perform purging
(vacuum is not detected at the purge hose) unless the en-
gine is sufficiently warmed up and the heated oxygen sen-
sor is activated fully. Also, when the purge hose is discon-
nected in Step 4), the air is drawn into the purge line. As a
result, ECM detects a change in the purge gas concentra-
tion and sometimes stops purging but this indicates noth-
ing abnormal.
If check result is not satisfactory, check vacuum passage, hoses,
EVAP canister purge valve, wire harness and ECM.
VACUUM PASSAGE INSPECTION
Start engine end run it at idle speed. Disconnect vacuum hose from
EVAP canister purge valve. With finger placed against hose discon-
nected, check that vacuum is applied.
If it is not applied, clean vacuum passage by blowing compressed
air.
VACUUM HOSE INSPECTION
Check hoses for connection, leakage, clog and deterioration. Re-
place as necessary.

5) Check fuel pressure as follows.
[Not using SUZUKI scan tool]
a) Turn ignition switch ON to operate fuel pump and after 2 seconds
turn it OFF. Repeat this 3 or 4 times and then check fuel pres-
sure.
b) Start engine and warm it up to normal operating temperature.
c) Measure fuel pressure at idling.
If measured pressure doesn’t satisfy specification, refer to
“Diagnostic Flow Table B-3” in “Engine Diagnosis” section and
check each possibly defective part. Replace if found defective.
d) After checking fuel pressure, remove fuel pressure gauge.
CAUTION:
As fuel feed line is still under high fuel pressure, make
sure to release fuel pressure according to following pro-
cedures.

Place fuel container under joint.

Cover joint with rag and loosen joint nut slowly to re-
lease fuel pressure gradually.
e) Remove special tools from fuel delivery pipe.
f) Connect fuel feed hose to fuel delivery pipe and clamp it secure-
ly.
g) With engine OFF and ignition switch ON, check for fuel leaks.
