PRECAUTIONS
4. Cover the serrated end of the valve with a large shop towel (A).
Strike the valve face end with a hammer, separating it into two
pieces.
5. Fill a bucket, such as a 20 (5-1/4 US gal, 4-3/8 Imp gal) oil can, with at least 10 (2-5/8 US gal, 2-1/4 lmp gal) of water.
Carefully place the already cut (serrated) valves into the water
one-at-a-time using a set of large tweezers and quickly move
away at least 2.7 m (9 ft).
6. The valves should be placed in a standing position as shown in the illustration to allow complete reaction. After the bubbling
action has subsided, additional valves can be placed into the
bucket allowing each subsequent chemical reaction to subside.
However, no more than 8 valves should be placed in the same
10 (2-5/8 US gal, 2-1/4 lmp gal) amount of water. The com-
plete chemical reaction may take as long as 4 to 5 hours.
Remove the valves using a set of large tweezers after the chem-
ical reaction has stopped. Afterwards, valves can be disposed
as ordinary scrap.
Precaution for Assembly and InstallationINFOID:0000000009460458
• Use torque wrench to tighten bolts or nuts.
• When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified,
follow the specifications.
• Always replace the old with a new gas ket, packing, oil seal or O-ring.
• Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction
and blockage.
• Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
• Bleed the air trapped within the system after draining the coolant.
• Before starting engine, apply fuel pressure to fuel li nes with turning ignition switch ON (with engine stopped).
Then make sure that there are no leaks at fuel line connections.
• After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for leakage or rattles.
Parts Requiring Angular TighteningINFOID:0000000009460459
• Use an angle wrench for the final tightening of the following engine parts.
- Cylinder head bolts
- Lower cylinder block bolts
- Connecting rod cap bolts
- Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular tightening)
• Do not use a torque value for final tightening.
• The torque value for these parts are for a preliminary step.
• Ensure thread and seat surfaces are clean and coated with engine oil.

FUEL INJECTOR AND FUEL TUBE
5. Remove quick connector cap (1) from the fuel feed side (B) and
the fuel tube side (A).
6. Disconnect the fuel hose quick connector at the fuel tube side using Tool (D).
CAUTION:
• Do not pull with lateral force applied. O-ring inside quick connector may be damaged.
• Prepare container and cloth beforehand as fuel will leak out.
• Avoid fire and sparks.
• Be sure to cover openings of disconnected pipes with
plug or plastic bag to avoid fuel leaks and entry of foreign
materials.
• Do not reuse O-ring.
a. With the sleeve (E) side of Tool (D) facing quick connector, install Tool onto fuel tube.
b. Insert Tool into quick connector until sleeve contacts and goes no further (A). Hold the Tool on that posi-
tion.
CAUTION:
Inserting the Tool hard will not disconnect quick connector. Hold Tool where it contacts and goes
no further.
c. Hold the fuel tube in the location (B) and pull the quick connector straight out in direction (C) from the fuel
tube.
7. Disconnect the EVAP canister purge volume control solenoid.
8. Remove the PCV hose from the rocker cover.
9. Disconnect sub-harness for injectors at engine front side, and remove it from bracket.
10. Disconnect the fuel injector harness connectors.
11. Loosen the bolts in the reverse order shown, then remove fuel tube and fuel injectors as an assembly.
12. Remove the fuel injectors from the fuel tube, (if necessary).
a. Release the clip.
b. Pull fuel injector straight out of the fuel tube. CAUTION:
• Be careful not to damage the nozzle.
• Avoid any impact, such as dropping the fuel injector.
• Do not disassemble or adjust the fuel injector.
INSTALLATION
1. Install new O-rings on the fuel injector.
CAUTION:
• Do not reuse O-rings.
• Upper and lower O-rings are different. Be careful not to confuse them.

FUEL INJECTOR AND FUEL TUBE
c. Align center to insert quick connector straight onto fuel tube.
d. Insert fuel tube into quick connector (1) until the top spool (B) on fuel tubes is inserted completely and the second level spool (C)
is positioned slightly below the quick connector bottom end.
CAUTION:
• Hold at position (A) as show n, when inserting the fuel
tube into the quick connector.
• Carefully align to center to avoid inclined insertion to pre-
vent damage to the O-ring inside the quick connector.
• Insert the fuel tube 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.
• Do not reuse O-ring.
e. Before clamping the fuel hose with the hose clamp, pull the quick connector hard by hand, holding at the
(A) position, as shown. Make sure it is completely engaged (connected) so that it does not come off of the
fuel tube.
NOTE:
Recommended pulling force is 50 N (5.1 kg, 11.2 lb).
f. Install quick connector cap (1) over fuel hose side (B) and fuel tube side (A).
NOTE:
Direct arrow mark on quick connector cap (1) to fuel hose side.
5. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Make sure there are no fuel leaks at connections as follows:
1. Apply fuel pressure to fuel lines by turning ignition switch ON (with engine stopped). Then check for fuel leaks at connections.
2. Start the engine and rev it up and check for fuel leaks at connections. • Perform procedures for “Throttle Valve Closed Posi tion Learning” after finishing repairs. Refer to EC-
178, "Work Procedure".
• If electric throttle control actuator is replaced, perform procedures for “Idle Air Volume Learning” after
finishing repairs. Refer to EC-179, "Work Procedure"
.
WARNING:
Do not touch engine immediately after stopping as engine is extremely hot.
NOTE:
Use mirrors for checking on connections out of the direct line of sight.
