PRECAUTIONS


When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is speci-
fied, do exactly as specified.

Replace with new gasket, packing, oil seal or O-ring.

Dowel pins are used for several parts alignment. When replacing and reassemling with dowel pins, make
sure that dowel pins are installed in the original portion.

Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction
and blockage.

Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.

Release air within route when refilling after draining coolant.

Before starting engine, apply fuel pressure to fuel lines with turning ignition switch “ON” (with engine
stopped). Then make sure that there are no leaks at fuel line connections.

After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust gases for leakage.
Parts Requiring Angle TighteningBBS005KN

Use angle wrench [SST: KV10112100] for the final tightening of the following engine parts.
–Cylinder head bolts
–Lower cylinder block bolts
–Connecting rod cap bolts
–Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angle
tightening)
–Balancer unit

Do not use a torque value for final tightening.

The torque value for these parts are for a preliminary step.

Ensure thread and seat surfaces are clean and coated with engine oil.
Precautions For Liquid GasketBBS005KO
REMOVAL OF LIQUID GASKET

After removing the mounting nuts and bolts, separate the mating
surface using seal cutter (SST) and remove the old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.

Tap seal cutter to insert it, and then slide it by tapping on the
side as shown in the figure.

In areas where seal cutter is difficult to use, use plastic hammer
to lightly tap the areas where the liquid gasket is applied.
CAUTION:
If for some unavoidable reason tool such as screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using scraper, remove the old liquid gasket adhering to the liq-
uid gasket application surface and the mating surface.

Remove the liquid gasket completely from the groove of the
liquid gasket application surface, mounting bolts and bolt
holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

UNDER SEATING AREAS
An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides)
during vehicle vibration. If the wiring runs under seating areas, inspect wire routing for possible damage or
pinching.
Heat Sensitive
The customer's concern may occur during hot weather or after car
has sat for a short time. In such cases you will want to check for a
heat sensitive condition.
To determine if an electrical component is heat sensitive, heat the
component with a heat gun or equivalent.
Do not heat components above 60°C (140°F). If incident occurs
while heating the unit, either replace or properly insulate the compo-
nent.
Freezing
The customer may indicate the incident goes away after the car
warms up (winter time). The cause could be related to water freezing
somewhere in the wiring/electrical system.
There are two methods to check for this. The first is to arrange for
the owner to leave his car overnight. Make sure it will get cold
enough to demonstrate his complaint. Leave the car parked outside
overnight. In the morning, do a quick and thorough diagnosis of
those electrical components which could be affected.
The second method is to put the suspect component into a freezer
long enough for any water to freeze. Reinstall the part into the car
and check for the reoccurrence of the incident. If it occurs, repair or
replace the component.
Water Intrusion
The incident may occur only during high humidity or in rainy/snowy
weather. In such cases the incident could be caused by water intru-
sion on an electrical part. This can be simulated by soaking the car
or running it through a car wash.
Do not spray water directly on any electrical components.
Electrical Load
The incident may be electrical load sensitive. Perform diagnosis with
all accessories (including A/C, rear window defogger, radio, fog
lamps) turned on.

DOOR MIRROR

DOOR MIRRORPFP:96301
Precautions to Handle Retractable Power Door MirrorsBIS0010G

Do not manually operate retractable power door mirrors. If mirror
is operated manually, be sure to use the retracting switch to
move mirror fully to the opposite direction until it stops. In this
case, a loud click sound is heard, but it is not abnormal. (If mirror
body is manually moved to the neutral position, door mirror will
have some disturbing symptoms during driving, including vibra-
tion, rough retracting movement, or sometimes no retracting.)
CAUTION:
Tilting mirror body forward with excessive force may dam-
age it.

When operating retracting switch to move mirror from the neu-
tral position to the fully-closed (backward limit) position, at the
beginning of the movement a faint click sound is heard, but it is not abnormal.

RH and LH retractable power door mirror bodies have different mounting angles in the neutral position.
This is why the RH mirror body delays slightly when operated with the retracting switch.
NOTE:

When the retractable power door mirror body is in the neutral
position, if retracting switch is operated to the opening direc-
tion while pressing it forward, mirror body is moved to the for-
ward limit position, but it is not abnormal. In this case, be sure
to operate retracting switch to move mirror to the fully-closed
(backward limit) position.

When the retracting switch is operated continuously 5 times
or more, the retractable power door mirror may be inactivated
to prevent overheating. In this case, wait for approximately 5
minutes to recover.
