FUEL INJECTOR AND FUEL TUBE


Insert until you hear a “click” sound and actually feel the engagement.

To avoid misidentification of engagement with a similar sound, be sure to perform the next
step.
c. Before clamping fuel feed hose with hose clamps, pull quick connector hard by hand holding “A” position.
Make sure it is completely engaged (connected) so that it does not come out from fuel tube.
d. Install quick connector cap to quick connector connection. (On
both the engine side and the vehicle side)

Install so that the arrow mark on the side faces up.
CAUTION:

Make sure that quick connector and fuel tube are
securely fit into quick connector cap installation groove.

If quick connector cap cannot be installed smoothly,
quick connector may have not been installed correctly.
Check connection again.
NOTE:
There is quick connector cap for the engine side and for the
vehicle side, and they have different shapes. The figure shows engine side as an example.
8. Install fuel feed hose to hose clamp.
9. Install in the reverse order of removal after this step.
INSPECTION AFTER INSTALLATION
Check on Fuel Leaks
1. Apply fuel pressure to fuel lines with turning ignition switch “ON” (with engine stopped). Then make sure
there are no fuel leaks at connections.
NOTE:
Use mirrors for checking on invisible points.
2. Start engine. With engine speed increased, make sure again there are no fuel leaks at connections.
CAUTION:
Do not touch the engine immediately after stopped as engine becomes extremely hot.

CAUTION:
After installation, pull the stopper pin off completely, and make sure that chain tensioner plunger
is released.
8. Install chain guide.
9. Install intake valve timing control cover with the following procedure:
a. Install oil rings to the intake camshaft sprocket insertion points on backside of intake valve timing control
cover.
b. Install O-ring to front cover.
c. Apply liquid gasket with tube presser [SST: WS39930000] to
intake valve timing control cover as shown in the figure.
Use Genuine Liquid Gasket or equivalent.
d. Tighten mounting bolts in numerical order as shown in the fig-
ure.
e. Install intake valve timing control solenoid valve to intake valve timing control cover if removed.
f. Connect ground cables, and install harness clip.
10. Check and adjust valve clearance. Refer to EM-50, "
Valve Clearance" .
11. Install in the reverse order of removal after this step.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
INSPECTION AFTER INSTALLATION
Inspection of Camshaft Sprocket (INT) Oil Groove
CAUTION:

Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT-II
and it is directed according to inspection procedure of EC section. Refer to EC-82, "
SELF-DIAG
RESULTS MODE" .

Check when the engine is cold so as to prevent burns from any splashing engine oil.
1. Check the engine oil level. Refer to LU-7, "
ENGINE OIL" .
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Release fuel pressure. Refer to EC-49, "
FUEL PRESSURE RELEASE" .

f. Connect ground cables, and install harness clip.
10. Insert crankshaft pulley by aligning with crankshaft key.

When inserting crankshaft pulley with plastic hammer, tap on its center portion (not circumference).
CAUTION:
Install protecting front oil seal lip section from any damage.
11. Tighten crankshaft pulley bolt with the following procedure.

Secure crankshaft pulley with pulley holder [SST: KV10109300], and tighten crankshaft pulley bolt.
a. Apply new engine oil to thread and seat surfaces of crankshaft pulley bolt.
b. Tighten crankshaft pulley bolt.
c. Put a paint mark on crankshaft pulley, mating with any one of six
easy to recognize angle marks on bolt flange.
d. Turn another 60 degrees clockwise (angle tightening).

Check the tightening angle with movement of one angle mark.
12. Install all removed parts in the reverse order of removal.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-49, "
FUEL PRESSURE RELEASE" .
3. Disconnect fuel pump fuse to avoid fuel injection during mea-
surement.
4. Remove engine cover. Refer to EM-19, "
INTAKE MANIFOLD" .
5. Remove ignition coil and spark plug from each cylinder. Refer to EM-31, "
IGNITION COIL" and EM-32,
"SPARK PLUG(PLATINUM-TIPPED TYPE)" .
6. Connect engine tachometer (not required in use of CONSULT-II).
7. Install compression tester with adapter onto spark plug hole.

Use compression gauge 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 cylinder head during removal.
8. 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 (bar, kg/cm2 , psi) /rpm
CAUTION:
Always use a fully changed battery to obtain specified engine speed.

bolts.
b. Tighten all bolts.
c. Turn all bolts 60 degrees clockwise (angle tightening).
CAUTION:

wrench (SST) or protractor. Avoid judgment by visual
inspection without the tool.
d. Completely loosen.
CAUTION:
In this step, loosen bolts in reverse order of that indicated
in the figure.
e. Tighten all bolts.
f. Turn all bolts 75 degrees clockwise (angle tightening).
g. Turn all bolts 75 degrees clockwise again (angle tightening).
3. Install in the reverse order of removal after this step.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following 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-14, "
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. : 50.0 N·m (5.1 kg-m, 37 ft-lb)
: 0 N·m (0 kg-m, 0 ft-lb)
: 39.2 N·m (4.0 kg-m, 29 ft-lb)

Removal and InstallationBBS0059F
WARNING:

Situate vehicle on a flat and solid surface.

Place chocks at front and back of rear wheels.

For engines not equipped with engine slingers, attach proper slingers and bolts described in
PARTS CATALOG.
CAUTION:

Always be careful to work safely, avoid forceful or uninstructed operations.

Do not start working until exhaust system and engine coolant are cool enough.

If items or work required are not covered by the engine section, refer to the applicable sections.

Always use the support point specified for lifting.

Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for
unavoidable reasons, support at the rear axle jacking point with transmission jack or similar tool
before starting work, in preparation for the backward shift of center of gravity.

For supporting points for lifting and jacking point at rear axle, refer to GI-37, "Garage Jack and
Safety Stand and 2-Pole Lift" .
