Removal and InstallationNBS004OU
REMOVAL
WAR NING :
To avoid the danger of being scalded, never drain the engine coolant when the engine is hot.
1. Remove engine room cover (RH and LH). Refer to EM-173, "
ENGINE ROOM COVER" .
2. Remove engine cover with power tool.
3. Release fuel pressure. Refer to EC-809, "
FUEL PRESSURE RELEASE" .
4. Remove air duct (inlet), air cleaner case and air duct and resonator assembly. Refer to EM-177, "
AIR
CLEANER AND AIR DUCT" .
5. Drain engine coolant from radiator. Refer to CO-40, "
DRAINING ENGINE COOLANT" .
CAUTION:
Perform this step when the engine is cold.
Do not spill engine coolant on drive belts.

Exhaust Manifold Gasket
Install exhaust manifold gasket with its directional protrusion set
upward.
Exhaust Manifold
Install exhaust manifold and tighten mounting nuts in numerical
order as shown in the figure.
NOTE:
Tighten mounting nuts No. 1 to 4 in two steps. The numerical
order No. 9 to 12 shown second steps.
Air Fuel Ratio Sensor
CAUTION:
Before installing a new air fuel ratio sensor 1, clean exhaust system threads using oxygen sensor
thread cleaner (commercial service tool: J-43897-18 or J-43897-12), and apply anti-seize lubricant
(commercial service tool).
Do not over torque air fuel ratio sensor. Doing so may cause damage to the air fuel ratio sensor 1,
resulting in “MIL” coming on.

REMOVAL
1. Remove ignition coil. Refer to EM-190, "IGNITION COIL" .
2. Remove spark plug with spark plug wrench (commercial service
tool).
CAUTION:
Do not drop or shock it.
INSPECTION AFTER REMOVAL
Use standard type spark plug for normal condition.
Hot type spark plug is suitable when fouling occurs with standard type spark plug under conditions such as:
Frequent engine starts
Low ambient temperatures
Cold type spark plug is suitable when spark plug knock occurs with standard type spark plug under conditions
such as:
Extended highway driving
Frequent high engine revolution

7. Install oil pump drive spacer as follows:
a. Insert oil pump drive spacer according to the directions of crank-
shaft key and the two flat surfaces of oil pump inner rotor.
If the positional relationship does not allow the insertion,
rotate oil pump inner rotor with a finger to allow spacer.
b. After confirming that the position of each part is in correct condi-
tion to allow for spacer, force fit spacer by lightly tapping with
plastic hammer until it contacts and does not go further.
8. Install front oil seal on front cover.
Apply new engine oil to both oil seal lip and dust seal lip.
Install it so that each seal lip is oriented as shown in the fig-
ure.
CAUTION:
Be careful not to scratch or make burrs on circumference
of oil seal.
Using front oil seal drift (commercial service tool), press fit
until the height of front oil seal is level with the mounting sur-
face.
Make sure the garter spring is in position and seal lips not
inverted.
9. Install chain tensioner cover to front cover.
Apply a continuous bead of liquid gasket with tube presser
[SST: WS39930000 ( — )] to front cover as shown in the
figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
10. Install front cover as follows:
