5. Install the quick connector cap on the quick connector joint (on

engine side only).

6. Install the fuel hose and tube to hose clamps.
7. Refill the engine coolant. Refer to

CO-11, "Changing Engine

Coolant"

.

INSPECTION AFTER INSTALLATION

• After installing fuel tubes, make sure there is no fuel leakage at connections in the following steps.

- Apply fuel pressure to fuel lines by turning ignition switch ON (with engine stopped). Then check for fuel

leaks at connections.

- Start the engine and rev it up and check for fuel leaks at the connections.

• Perform procedures for “Throttle Valve Closed Position Learning” after finishing repairs. Refer to

EC-119,

"Throttle Valve Closed Position Learning"

.

• If electric throttle control actuator is replaced, perform procedures for “Idle Air Volume Learning” after finish-

ing repairs. Refer to

EC-120, "Idle Air Volume Learning"

.

b. Remove the air fuel ratio A/F sensors from both LH and RH

exhaust manifolds using Tool.

CAUTION:

• Do not damage the air fuel ratio A/F sensors

• Discard any air fuel ratio A/F sensor which has been

dropped from a height of more than 0.5 m (19.7 in) onto a

hard surface such as a concrete floor. Replace it with a

new one.

8. Support the engine using a suitable tool.
9. Remove the exhaust manifold (LH) (A) following the steps

below.
•

: Front

• B: Exhaust manifold (RH)

a. Remove the engine mounting insulator. Refer to

EM-84,

"Exploded View"

.

b. Remove the exhaust manifold cover.
c. Remove the engine mounting bracket. Refer to

EM-84,

"Exploded View"

.

d. Loosen the nuts in reverse order as shown using power tool.
e. Remove the exhaust manifold (LH) (A).

10. Remove the exhaust manifold (RH) (B) following the steps

below.
•

: Front

• A: Exhaust manifold (LH)

a. Remove the engine mounting insulator. Refer to

EM-84,

"Exploded View"

.

b. Remove the exhaust manifold cover.
c. Remove the engine mounting bracket. Refer to

EM-84,

"Exploded View"

.

d. Remove the oil level gauge guide. Refer to

View"

.

e. Loosen the nuts in reverse order as shown using power tool.
f.

Remove the exhaust manifold (RH) (B).

INSPECTION AFTER REMOVAL

Surface Distortion

• Check the flatness of each exhaust manifold flange surface using

suitable tools.

• If measurement exceeds the limit, replace the exhaust manifold.

INSTALLATION

Installation is in the reverse order of removal.

EXHAUST MANIFOLD AND THREE WAY CATALYST

• Install new exhaust manifold gasket with the top of the triangular

up mark on it facing up and its coated face (gray side) toward the

exhaust manifold side.

• Tighten the exhaust manifold nuts LH and RH in the numerical

order shown. Then recheck the torque of the nuts.

- A: Exhaust manifold LH

- B: Exhaust manifold RH
-

: Front

• Before installing new air fuel ratio A/F sensors, clean the exhaust system threads using suitable tool and

apply anti-seize lubricant.

CAUTION:

• Do not over tighten the air fuel ratio A/F sensors. Doing so may cause damage to the sensor,

resulting in the MIL coming on.
