5. Loosen nuts in reverse order as shown and remove exhaust
manifold.
CAUTION:
Cover engine openings to avoid entry of foreign materials.
INSPECTION AFTER REMOVAL
Surface Distortion
 Using straightedge (B) and feeler gauge (A), check the surface dis-
tortion of exhaust manifold mating surface in each exhaust port
and entire part.
 If it exceeds the limit, replace exhaust manifold.
INSTALLATION
1. Install exhaust manifold gasket to cylinder head as shown.
2. Tighten exhaust manifold nuts to specification in two stages in
the numerical order as shown.

3. Install exhaust manifold stay (2) in the direction as shown.
4. Install the heated oxygen sensor 1, using Tool
CAUTION:
 Handle it carefully and avoid impacts.
 Before installing a new heated oxygen sensor, clean the
exhaust tube threads using suitable tool and approved
anti-seize lubricant.
 Do not over-tighten the heated oxygen sensor. Doing so
may damage the heated oxygen sensor, resulting in the
MIL coming on.

FUEL INJECTOR AND FUEL TUBE
8. Remove fuel tube.
 Loosen bolts in reverse order as shown.
9. Remove the fuel tube and fuel injector assembly.
CAUTION:
 When removing, be careful to avoid any interference with fuel injector.
 Use a shop cloth to absorb any fuel leaks from fuel tube.
10. 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.
 Never bump or drop fuel injector.
 Never 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. Never wear gloves.
 Lubricate O-ring with new engine oil.
 Never 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, never insert it quickly
into fuel tube.
 Insert O-ring straight into fuel tube. Never twist it.

2. Install fuel injector (4) to fuel tube (1) with the following proce-
dure:
a. Insert clip (2) into clip groove (F) on fuel injector.
 Insert clip so that protrusion (G) of fuel injector matches cut-
out (D) of clip.
CAUTION:
 Never reuse clip. Replace it with a new one.
 Be careful to keep clip from interfering with O-ring. If
interference occurs, replace O-ring.
b. Insert fuel injector into fuel tube with clip attached.
 Insert it while matching it to the axial center.
 Insert fuel injector so that protrusion (B) of fuel tube matches
cut-out (C) of clip.
 Make sure that fuel tube flange (A) is securely fixed in flange
fixing groove (E) on clip.
c. Make sure that installation is complete by making sure that fuel
injector does not rotate or come off.
3. Set fuel tube and fuel injector assembly at its position for installation on cylinder head.
CAUTION:
For installation, be careful not to interfere with fuel injector nozzle.
