REMOVAL
1. Remove engine assembly from vehicle. Refer to EM-236, "ENGINE ASSEMBLY" .
2. Remove the following components and related parts:

Drive belt auto tensioner and idler pulley; Refer to EM-171, "Drive Belt Auto Tensioner and Idler Pulley"
.

Thermostat housing and hoses; Refer to CO-51, "THERMOSTAT AND WATER CONTROL VALVE" .

Ignition coil; Refer to EM-185, "IGNITION COIL" .

Rocker cover; Refer to EM-193, "ROCKER COVER" .
3. If necessary, remove intake valve timing control position sensor
(right and left bank) and camshaft position sensor (PHASE) from
intake valve timing control cover and front cover.
CAUTION:

Handle carefully to avoid dropping and shocks.

Do not disassemble.
4. If necessary, remove intake valve timing control solenoid valve from intake valve timing control cover.
CAUTION:

Handle components and parts carefully to avoid dropping and shocks.

Do not disassemble.

Do not allow metal powder to adhere to magnetic part at sensor tip.

Do not place sensors in a location where they are exposed to magnetism.

b. Install new O-rings on front cover.
c. Apply a continuous bead of liquid gasket with tube presser [SST:
WS3930000 ( — )] to intake valve timing control covers as
shown in the figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS".
d. Tighten mounting bolts in numerical order as shown in the fig-
ure.
12. Install intake valve timing control position sensor, intake valve timing control solenoid valve and camshaft
position sensor (PHASE) to intake valve timing control cover and front cover if removed.

Be sure to tighten bolts with flanges completely seated.
13. Install oil pan and oil strainer. Refer to EM-181, "
OIL PAN AND OIL STRAINER" .
14. Install crankshaft pulley as follows:
a. Fix crankshaft with ring gear stopper [SST: J-45476].
b. Install crankshaft pulley, taking care not to damage front oil seal.

Install according to dowel pin of oil pump drive spacer.

Lightly tapping its center with plastic hammer, insert pulley.
CAUTION:
Do not tap pulley on the side surface where belt is installed (outer circumference).
c. Apply engine oil onto threaded parts of crankshaft pulley bolt and seating area.
d. Tighten crankshaft pulley bolt.
e. Put a paint mark on crankshaft pulley aligning with angle mark on crankshaft pulley bolt.
