b.

Apply a continuous bead of liquid gasket with the tube presser
(commercial service tool) to intake valve timing control covers as
shown in the figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-44, "Recommended Chemical Product and Sealant"

.

c.

Install new collared O-rings in front timing chain case oil hole
(left and right sides).

d.

Being careful not to move seal ring from the installation groove, align dowel pins on front timing chain
case with holes to install intake valve timing control covers.

e.

Tighten mounting bolts in numerical order as shown in the fig-
ure.

16. Install oil pans (upper and lower). Refer to 

EM-30, "Component (2WD Models)"

.

17. Install rocker covers (right and left banks). Refer to 

EM-51, "Component"

.

18. Install crankshaft pulley as follows:
a.

Fix crankshaft using the ring gear stopper [SST: KV10117700 (J44716)].

b.

Install crankshaft pulley, taking care not to damage front oil seal.
• When press-fitting crankshaft pulley with plastic hammer, tap on its center portion (not circumference).

c.

Tighten crankshaft pulley bolt.

d.

Put a paint mark on crankshaft pulley aligning with angle mark on crankshaft pulley bolt.

e.

Further tighten by 90 degrees. (Angle tightening)
• Check the tightening angle by referencing to the notches. The

angle between two notches is 90 degrees.

19. Rotate crankshaft pulley in normal direction (clockwise when viewed from front) to confirm it turns

smoothly.

20. For the following operations, perform steps in the reverse order of removal.

INSPECTION AFTER INSTALLATION

Inspection for Leaks

The following are procedures for checking fluids leak, lubricates leak.

• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required

quantity, fill to the specified level. Refer to 

GI-44, "Recommended Chemical Product and Sealant"

.

• Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-

age at connection points.

- Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.

NOTE:
If hydraulic pressure inside chain tensioner drops after removal/installation, slack in guide may generate a
pounding noise during and just after the engine start. However, this does not indicate an unusualness. Noise
will stop after hydraulic pressure rises.

• Warm up engine thoroughly to make sure there is no leakage of fuel, or any oil/fluids including engine oil and

engine coolant.

• Bleed air from lines and hoses of applicable lines, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the

specified level, if necessary.

Summary of the inspection items:

*: Transmission/transaxle/CVT fluid. power steering fluid, brake fluid, etc.
