REASSEMBLY
HINT:

Thoroughly clean all parts to be assembled.

Before installing the parts, apply new engine oil to all slid-
ing and rotating surfaces.

Replace all gaskets, O±rings and oil seals with new ones.
1. ASSEMBLE PISTON AND CONNECTING ROD
(a) Using a screwdriver, install a new snap ring on one side
of the piston pin hole.
(b) Gradually heat the piston to about 60°C (140°F).
(c) Coat the piston pin with engine oil.
(d) Position the piston so that the front mark and to the out-
side mark on the connecting rod face in the same direc-
tion as shown in the illustration.
NOTICE:
The installation directions of the piston and connecting rod
are different for the LH and RH banks. The LH piston is
marked with 1 cavity and º2º, the RH piston with 2 cavities
and º2º.
(e) Align the piston pin holes of the piston and connecting
rod, and push in the piston pin with your thumb.
(f) Using a screwdriver, install a new snap ring on the other

PRECAUTION
HINT:
All DTCs retained in the ECM will be erased when the negative
(±) terminal cable is removed from the battery.
If necessary, read the DTC before removing the negative (±)
terminal cable from the battery.
1. BEFORE WORKING ON FUEL SYSTEM,
DISCON-
NECT CABLE FROM NEGATIVE (±) BATTERY TERMI-
NAL
2. DO NOT SMOKE OR WORK NEAR AN OPEN FLAME
WHEN WORKING ON FUEL SYSTEM
3. KEEP GASOLINE AWAY FROM RUBBER OR
LEATH-
ER PARTS
4. MAINTENANCE PRECAUTIONS
(a) To prevent engine misfire, these precautions should be
taken.
(1) Check the battery terminals are proper connected.
(2) After repair, check that the ignition coil terminals
and all other ignition system lines are reconnected
securely.
(3) When cleaning the engine compartment, be espe-
cially careful to protect the electrical system from
water.
(b) Observe the following when handling the air fuel ratio
sensors and oxygen sensor.
(1) Do not drop the sensor or hit it against another ob-
ject.
(2) The sensor should be free from any contact with wa-
ter.
5. IF VEHICLE IS EQUIPPED WITH MOBILE RA-
DIO
SYSTEM (HAM, CB, ETC.)
If the vehicle is equipped with a mobile communication system,
refer to the precaution in the IN section.
6. AIR INDUCTION SYSTEM
(a) Removal of the engine oil dipstick, oil filler cap, PCV hose,
may break the engine.
(b) Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head may result in air suction and break the engine.
7. ELECTRONIC CONTROL SYSTEM
(a) Before removing SFI wiring connectors, terminals, first
disconnect the power by turning the ignition switch off or
disconnecting the negative (±) terminal cable from the
battery.
HINT:
Be sure to check DTCs before disconnecting the negative (±)
terminal cable from the battery.
