b. With the sleeve side of quick connector release facing quick connector, install quick connector release
onto fuel tube.
c. 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 release hard will not disconnect
quick connector. Hold quick connector release where it
contacts and goes no further.
d. Draw and pull out quick connector straight from fuel tube.
CAUTION:

Pull quick connector holding “A” position in the figure.

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.

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 connector and fuel feed hose during installa-
tion/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. Remove PCV hose. Refer to EM-18, "
Removal and Installation (QR20DE)" .
5. Disconnect harness connector from ignition coil.
6. Remove sub-harness for fuel injector.
7. Remove electric throttle control actuator and intake manifold support. Refer to EM-18, "
Removal and
Installation (QR20DE)" .
8. Loosen mounting bolts in reverse order as shown in the figure.
9. Remove fuel tube protector.
10. Pull out fuel tube and fuel injector assembly rearward of engine.
CAUTION:

When removing, be careful to avoid any interference with fuel injector.

Use a shop cloth to absorb any fuel leaks from fuel tube.

11. Remove fuel injector from fuel tube with the following procedure:
a. Open and remove clip.
b. Remove fuel injector from fuel tube by pulling straight.
CAUTION:

Be careful with remaining fuel that may go out from fuel
tube.

Be careful not to damage fuel injector nozzle during
removal.

Do not bump or drop fuel injector.

Do not disassemble fuel injector.
INSTALLATION
1. Note the following, and install O-rings to fuel injector.
CAUTION:

Upper and lower O-rings are different. Be careful not to confuse them.

Handle O-ring with bare hands. Do not wear gloves.

Lubricate O-ring with new engine oil.

Do not clean O-ring with solvent.

Make sure that O-ring and its mating part are free of foreign material.

When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not to
twist or stretch O-ring. If O-ring was stretched while it was being attached, do not insert it
quickly into fuel tube.

Insert O-ring straight into fuel tube. Do not decenter or twist it.

INSTALLATION
NOTE:
The figure shows the relationship between the mating mark on each
timing chain and that on the corresponding sprocket, with the com-
ponents installed.
1. Make sure that crankshaft key points straight up.
2. Tighten mounting bolts in numerical order as shown in figure
with the following procedure, and install balancer unit.
CAUTION:
If mounting bolts are re-used, check their outer diameter
before installation. Refer to EM-50, "
INSPECTION AFTER
REMOVAL" .
a. Apply new engine oil to threads and seat surfaces of mounting
bolts.
b. Tighten all bolts.
c. Turn all bolts 90 degrees clockwise (angle tightening).
d. Completely loosen.
CAUTION:
In this step, loosen bolts in reverse order as shown in the
figure.
e. Tighten all bolts.
f. Turn them another 90 degrees clockwise (angle tightening).
CAUTION:
Check tightening angle with an angle wrench (special service tool) or a protractor. Do not make
judgment by visual check alone.
