1. Tighten exhaust manifold nuts to specification in two stages in
the numerical order shown.
2. Use Tool (A) to install the air fuel ratio sensor 1. CAUTION:
• Handle it carefully and avoid impacts.
• Before installing a new air fu el ratio sensor 1, clean the
exhaust tube threads using suitable tool and approved
anti-seize lubricant.
• Do not over-tighten the air fu el ratio sensor 1. Doing so
may damage the air fuel rati o sensor 1, resulting in the
MIL coming on. : Engine front ALBIA0625ZZ

a. Remove quick connector cap (1) from quick connector connec-
tion.
b. Disconnect fuel feed hose from hose clamp.
c. With the sleeve side of quick connector release facing quick connector, install quick connector release onto fuel tube.
d. Insert quick connector release into quick connector until sleeve contacts and goes no further. Hold quick connector release on
that position.
CAUTION:
Inserting quick connector re lease hard will not disconnect
quick connector. Hold qui ck connector release where it
contacts and goes no further.
e. Draw and pull out quick connector straight from fuel tube. CAUTION:
• Pull quick connector holding “A” position.
• Do not pull with lateral force applied. O-ring inside quick
connector may be damaged.
• Prepare container and cloth be forehand as fuel will leak out.
• Avoid fire and sparks.
• Keep parts away from heat source. Especially, be careful when welding is performed around
them.
• Do not expose parts to battery electrolyte or other acids.
• Do not bend or twist connection between quick co nnector and fuel feed hose during installation/
removal.
• To keep clean the connecting portion and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.
4. Disconnect harness connector from fuel injector.
5. Remove fuel tube protector. • Loosen bolts in the reverse of the order shown. KBIA0702E

2. Install the fuel injector (4) onto the fuel tube (1) with the following
procedure:
a. Insert the clips (2) into the clip mounting grooves on the fuel injector.
• Insert clip cut-out (D) into fuel injector protrusion (F). CAUTION:
• Always replace clip with new one.
• Make sure that the clip do es not interfere with the O-
ring. If interference occurs, replace the O-ring.
b. Insert the fuel injector into the fuel tube with clip attached. • Make sure that the axis is lined up when inserting.
• Insert clip cut-out (C) into fuel tube protrusion (B).
• Make sure that the flange (A) on the fuel tube fits securely in the clip flange fixing groove (E).
c. Make sure that installation is complete by checking that fuel injector does not rotate or come off.
3. Install fuel tube and injector assembly onto cylinder head. • Tighten bolts in the numerical order shown.
CAUTION:
Be careful not to let tip of injector nozzle interfere with
other parts.
4. Install fuel tube protector. • Tighten bolts in the numerical order shown.
5. Connect harness connector to fuel injector.
6. Connect fuel feed hose with the following procedure.
a. Check for damage or foreign material on the fuel tube and quick connector.
b. Apply new engine oil lightly to area around the top of fuel tube. 3 : O-ring (Black)
