• Use a reliable straightedge and f
eeler gauge to check the flatness
of the exhaust manifold mating surfaces.
• Replace the exhaust manifold if the measurement exceeds specifi- cations.
INSTALLATION
Installation is in the reverse order of removal.
1. Install the studs in the exhaust manifold (if removed), and tighten to specification.
2. Install the exhaust manifold gasket in the direction shown. CAUTION:
Do not reuse exhaust manifold gaskets.
3. Install the exhaust manifold (LH) nuts and tighten to specifica- tion in the order shown.
NOTE:
Number 7 and 8 are tightened a second time.
CAUTION:
• Before installing a heated oxyg en sensor 2 or air fuel ratio (A/F) sensor 1, clean the exhaust
manifold threads using the oxyg en sensor thread cleaner tool and apply anti-seize lubricant.
• Do not over-tighten the air fuel ratio (A/F) senso r 1 or heated oxygen sensors 2. Doing so may
cause damage.

nect the harness from the bracket and middle clamp.
b. Remove both heated oxygen sensors 2 and air fuel ratio (A/F) sensors 1 using Tool.
CAUTION:
• Be careful not to damage heated oxygen sen sors 2 or air fuel ratio (A/F) sensors 1.
• Discard any heated oxygen sensor 2 which has been dropped from a height of more than 0.5 m
(19.7 in) onto a hard surface such as a co ncrete floor; replace with a new sensor.
5. Remove exhaust manifold heat shield (RH) and three way catalyst heat shields (RH) using power tool.
6. Remove the three way catalyst (bank 1) by loosening the bolts first and then removing the nuts and through bolts.

• Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner dr ops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leak age of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.
