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.
a. Remove the engine mounting insulator. Refer to
b. Remove the exhaust manifold cover.
c. Remove the engine mounting bracket. Refer to
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.
a. Remove the engine mounting insulator. Refer to
b. Remove the exhaust manifold cover.
c. Remove the engine mounting bracket. Refer to
d. Remove the oil level gauge guide. Refer to
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.
• 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.
