Precaution for Liquid GasketINFOID:0000000001381456
REMOVAL OF LIQUID GASKET
 After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter and remove the liquid gasket.
CAUTION:
Be careful not to damage the mating surfaces.
 In areas where the cutter is difficult to use, use a plastic hammer to
lightly tap the liquid gasket applied area.
CAUTION:
If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating sur-
faces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the
gasket application surface and the mating surface.
 Remove the liquid gasket completely from the groove of the
gasket application surface, mounting bolts and bolt holes.
2. Wipe the gasket application surface and the mating surface with
white gasoline (lighting and heating use) to remove adhering
moisture, grease and foreign materials.
3. Attach the liquid gasket to the tube presser.
Use Genuine Liquid Gasket or equivalent.
4. Apply the liquid gasket without breaks to the specified location
with the specified dimensions.
 If there is a groove for the liquid gasket application, apply the
gasket to the groove.
 As for the bolt holes, normally apply the gasket inside the
holes. If specified, it should be applied outside the holes. Make
sure to read the instruction in this manual.
 Within five minutes of gasket application, install the mating
component.
 If the liquid gasket protrudes, wipe it off immediately.
 Do not retighten after the installation.
 After 30 minutes or more have passed from the installation, fill
the engine oil and coolant.
CAUTION:
If there are instructions in this manual, observe them.

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.
CAUTION:
Do not heat components above 60°C (140°).
 If incident occurs while heating the unit, either replace or properly
insulate the component.
FREEZING
 The customer may indicate the incident goes away after the car
warms up (winter time). The cause could be related to water freez-
ing 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 out-
side 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.
CAUTION:
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.
COLD OR HOT START UP
On some occasions an electrical incident may occur only when the car is started cold, or it may occur when
the car is restarted hot shortly after being turned off. In these cases you may have to keep the car overnight to
make a proper diagnosis.
