NOTE:
To remove timing chain and related parts, start with those on left bank. The procedure for removing parts
on right bank is omitted because it is the same as that for left bank.
a. Press tab in the direction of arrow (or turn lever in the direction of arrow) to unlock the locking with the groove that stops ten-
sioner plunger from returning.

Lightly press tensioner plunger to release the tension of
spring for this operation.
b. Push in tensioner plunger to align the hole on lever and that on pump main body.

Pushing in tensioner too far does not allow the holes to align.
Therefore, push in plunger to the degree at which the start of
stopper groove and tab engages.
c. Insert stopper pin [hard wire with approx. 0.5 mm (0.020 in) diameter or similar tool] to fix plunger. With plunger fixed, remove chain tensioner.
17. Remove chain tension guide and timing chain slack guide.
18. Remove timing chain and crankshaft sprocket.
CAUTION:
After removing timing chain, do not turn crankshaft and camshaft separately, or valves will strike
the piston head.
19. With hexagonal part of camshaft locked with wrench, loosen mounting bolts securing camshaft sprocket to remove camshaft
sprocket.
CAUTION:
Do not loosen mounting bolts with securing anything other
than the camshaft hexagonal portion or with tensioning the
timing chain.
20. Perform same procedure as for left bank, remove timing chain and related parts on right side.
21. Use scraper to remove all traces of old liquid gasket from front cover and opposite mating surfaces.

Remove oil liquid gasket from bolt hole and thread.
22. Use scraper to remove all trace of liquid gasket from chain tensioner cover and intake valve timing control covers.

f. Further tighten by 90 degrees. (Angle tightening)

Check the tightening angle by referencing to the notches. The
angle between two notches is 90 degrees.
15. Rotate crankshaft pulley in normal direction (clockwise when viewed from engine front) to confirm it turns smoothly.
16. Install in the reverse order of removal after this step. NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in guide may gen-
erate a pounding noise during and just after engine start. However, this does not indicate an unusualness.
Noise will stop after hydraulic pressure rises.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The followings are procedures for checking fluids leak, lubricates leak and exhaust gases 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 MA-12, "
RECOMMENDED FLUIDS AND LUBRICANTS"

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
leakage 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.

Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, 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.

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-747, "
FUEL PRESSURE RELEASE" .
a. Remove fuel pump fuse to avoid fuel injection during measure- ment.
3. Remove engine cover with power tool. Refer to EM-173, "
ENGINE ROOM COVER" .
4. Remove ignition coil and spark plug from each cylinder. Refer to EM-191, "
IGNITION COIL" and EM-192,
"SPARK PLUG (PLATINUM-TIPPED TYPE)" .
5. Connect engine tachometer (not required in use of CONSULT-II).
6. Install compression gauge with adapter (SST or commercial ser- vice tool) onto spark plug hole.

Use compression gauge adapter (SST) which is required on
No. 7 and 8 cylinders.

Use compression gauge adapter (if no SST is used) whose
picking up end inserted to spark plug hole is smaller than 20
mm (0.79 in) in diameter. Otherwise, it may be caught by cyl-
inder head during removal.
7. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge pointer stabilizes, read the compression pressure and engine rpm. Perform these steps to check each cyl-
inder.
Compression pressure:
Unit: kPa (kg/cm2 , psi) /rpm
CAUTION:
Always use a fully changed battery to obtain the specified engine speed.

Separation Work
1. Change engine slinger installing to cylinder head (right bank).
NOTE:
In order to keep secure position when hoisting engine.
2. Remove engine mounting insulators (RH and LH) under side nut with power tool.
3. Lift with hoist and separate engine and transmission assembly from front suspension member. CAUTION:

Before and during this lifting, always make sure that any harnesses are left connected.

Avoid damage to and oil/grease smearing or spills onto engine mounting insulator.
4. Remove alternator. Refer to SC-24, "
CHARGING SYSTEM" .
5. Remove starter motor. Refer to SC-11, "
STARTING SYSTEM" .
6. Separate engine from transmission assembly. Refer to AT- 2 6 9 , "
Removal and Installation (AWD Models)"
.
7. Remove front final drive from engine. Refer to FFD-13, "
FRONT FINAL DRIVE ASSEMBLY" .
8. Remove engine mounting insulators (RH and LH) and brackets (RH and LH) from engine with power tool.
9. Remove engine rear member and engine mounting insulator (rear) from transmission.
INSTALLATION
Note the following, and install in the reverse order of removal.

Do not allow engine mounting insulator to be damage and careful no engine oil gets on it.

For a location with a positioning pin, insert it securely into hole of mating part.

For a part with a specified installation orientation, refer to component figure in EM-243, "Removal and
Installation" .

When installing engine mounting brackets (RH and LH) on cylin-
der block, tighten two upper bolts (shown as “A” in the figure)
first. Then tighten two lower bolts (shown as “B” in the figure).
