REMOVAL
WARNING:
• Perform the work when the exhaust system has completely cooled down.
• When removing the front and rear engine mounting th rough bolts and nuts, lift the engine up slightly
for safety.
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.
1. Remove the air cleaner assembly, and air duct hose and resonator assembly. Refer to EM-144, "Removal
and Installation".
2. Remove the battery and battery tray assembly. Refer to PG-74, "Removal and Installation (Battery Tray)"
.
3. Remove the engine under cover. Refer to EXT-28, "Removal and Installation"
.
4. Remove the radiator assembly. Refer to CO-41, "Removal and Installation"
.
5. Remove the engine cooling fan shroud and motor assembly. Refer to CO-42, "Removal and Installation"
.
6. Remove the front exhaust tube. Refer to EX-10, "Exploded View"
.
7. Remove the LH three way catalyst support brackets.
8. Remove heated oxygen sensor 2 (bank 2), air fuel ratio (A/F) sensor 1 (bank 2).
a. Remove harness connector of each sensor, and di sconnect the harness from the bracket and middle
clamp.
b. Remove both heated oxygen sensor 2 and air fuel ratio (A/F) sensor 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.
9. Remove exhaust manifold heat shield (LH) and three way catalyst heat shields (LH) using power tool.
10. Remove the three way catalyst (bank 2) by loosening the bolts first and then removing the nuts and through bolts.
11. Loosen and remove the exhaust manifold nuts in the reverse order as shown.

• 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.

a. Insert Tool (A) between the lower oil pan and the upper oil pan.
CAUTION:
• Be careful not to damage the mating surface.
• Do not insert a screwdriver or similar tool, this will dam-
age the mating surfaces.
b. In areas where the cutter is difficult to use, use a plastic hammer to lightly tap (1) the cutter where the liquid gasket is applied. Use
a plastic hammer to slide (2) the cutter by tapping on the side.
4. If re-installing the original lower oil pan, remove the old liquid gasket from the mating surfaces using a scraper.
• Also remove the old liquid gasket from mating surface of the upper oil pan.
• Remove the old liquid gasket from the bolt holes and threads.
CAUTION:
Do not scratch or damage the mating surf aces when cleaning off the old liquid gasket.
INSPECTION AFTER REMOVAL
Clean oil strainer if any object is attached.
INSTALLATION
1. Apply a continuous bead of liquid gasket to the lower oil pan.
• Use Genuine Silicone RTV Sealant, or equivalent. Refer to GI-
21, "Recommended Chemical Products and Sealants".
• Be sure the liquid gasket is 4.5 - 5.5 mm (0.177 - 0.217 in) wide.
• Installation must be done within 5 minutes after applying liquid gasket.
2. Install the lower oil pan. Tighten the lower oil pan bolts in order as shown.
• Wait at least 30 minutes before refilling the engine with oil.
INSPECTION AFTER INSTALLATION
• Start the engine and check for leaks. Refer to LU-25, "Inspection".
• Inspect the engine oil level. Refer to LU-25, "Inspection"
.
