Exhaust System InspectionS7RS0B0206006
WARNING! 
To avoid danger of being burned, do not 
touch exhaust system when it is still hot.
Any service on exhaust system should be 
performed when it is cool.
 
When carrying out periodic maintenance, or the vehicle 
is raised for other service, check exhaust system as 
follows:
• Check rubber mountings for damage, deterioration,  and out of position.
• Check exhaust system for leakage, loose  connections, dents and damages.
If bolts or nuts are loose,  tighten them to specification.
• Check nearby body areas for damaged, missing or  mispositioned parts, ope n seams, holes, loose 
connections or other defects which could permit 
exhaust fumes to seep into the vehicle.
• Make sure that exhaust system components have  enough clearance from the underbody to avoid 
overheating and possible damage to floor carpet.
• Any defects should be fixed at once.
Spark Plug ReplacementS7RS0B0206007
Replace spark plugs with new ones referring to “Spark 
Plug Removal and Installation in Section 1H”.
Air Cleaner Filter InspectionS7RS0B0206008
1) Remove air cleaner case clamps.
2) Take air cleaner filter out of case.
3) Check that filter is not excessively dirty, damaged or  oily, clean filter with compressed air from air outlet 
side of filter.
4) Install air cleaner filter  and Clamp cap securely.
Air Cleaner Filter ReplacementS7RS0B0206009
Replace air cleaner filter with new one according to 
Steps 1), 2) and 4) of “Air Cleaner Filter Inspection”.
Fuel Lines and Connections InspectionS7RS0B0206010
Visually inspect fuel lines and connections for evidence 
of fuel leakage, hose cracking and damage. Make sure 
all clamps are secure.
Repair leaky joints, if any.
Replace hoses that are suspected of being cracked.

2) Remove oil, old sealant, and dust from sealing surfaces on cylinder head and cover. After cleaning, 
apply sealant “A” to the following point.
• Cylinder head cover gasket (1) sealing surface area (2) as shown.
“A”:  Water tight sealant 99000–31250 
(SUZUKI Bond No.1207F) 
• Timing chain cover (1) and cylinder head (2)  mating surface as shown.
“A”:  Water tight sealant 99000–31250 
(SUZUKI Bond No.1207F)  3) Install cylinder head cover to cylinder head.
NOTE
When installing cylinder head cover, use care 
so that cylinder head cover gasket or spark 
plug hole gaskets will not get out of place or 
fall off.
 
4) Tighten cylinder head cover bolts as follows.
a) Tighten cylinder head cover bolts to 3 N ⋅m (0.3 
kgf-m, 2.5 lb-ft) according to numerical order (“1” 
through “7”) as shown in figure.
b) In the same manner as  in Step, a) tighten them 
to 5 N ⋅m (0.5 kgf-m, 4.0 lb-ft).
c) Retighten them by turning through 8 N ⋅m (0.8 
kgf-m, 6.0 lb-ft) in same manner as Step a).

N ⋅m (0.8 kgf-m, 6.0 lb-ft) by the specified 
procedure
5) Connect PCV hose (2) to PCV valve (3).
6) Connect breather hose (4).
7) Install oil level gauge (1).
8) Install wire harness clamp to cylinder head cover.
9) Install ignition coil assemb lies with high-tension cord 
referring to “Ignit ion Coil Assembly (Including ignitor) 
Removal and Installati on in Section 1H”.

1) Remove air cleaner assembly with air intake pipe.
2) Disconnect all injector couplers from injectors.
WARNING! 
Without disconnection of injector couplers, 
combustible gas may come out from spark 
plug holes during this test and may get 
ignited in engine room.
 
3) Remove spark plug and check it for condition and 
type referring to “Spark Plug Inspection”.
4) If OK, connect ignition coil coupler to ignition coil  assembly and connect spark plug to ignition coil 
assembly or high-tension cord. Ground spark plug. 5) Crank engine and check if each spark plug sparks.
6) If no spark is emitted, inspect the related parts as 
described in “Ignition System Symptom Diagnosis”.
Repair Instructions
High-Tension Cord Removal and InstallationS7RS0B1806001
Removal
1) Remove air cleaner assembly with air intake pipe  and cylinder head upper cover.
2) Disconnect No.1 cylinder  (2) and No.3 cylinder (3) 
high-tension cords from ignition coil assemblies (1) 
while gripping each cap.
3) Pull out high-tension cords from spark plugs while  gripping each cap.
CAUTION! 
• Removal of high-tension cords together with clamps will be recommended so as 
not to damage their inside wire (resistive 
conductor).
• For the same reason, pull out each  connection by gripping cap portion.
 
Installation
1) Install No.1 cylinder (2)  and No.3 cylinder (3) high-
tension cords to spark plugs and ignition coil 
assemblies (1) while gripping each cap.
CAUTION! 
• Never attempt to use metal conductor  high-tension cords as replacing parts.
• Insert each cap portion fully when  installing high-tension cords.
