0A-6 GENERAL INFORMATION
GENERAL PRECAUTIONS
The WARNING and CAUTION below describe some general precautions that you should observe when servicing
a vehicle. These general precautions apply to many of the service procedures described in this manual, and they
will not necessarily be repeated with each procedure to which they apply.
WARNING:
Whenever raising a vehicle for service, be sure to follow the instructions under “VEHICLE LIFTING
POINTS” on SECTION 0A.
When it is necessary to do service work with the engine running, make sure that the parking brake
is set fully and the transmission is in Neutral (for manual transmission vehicles) or Park (for automatic
transmission vehicles). Keep hands, hair, clothing, tools, etc. away from the fan and belts when the
engine is running.
When it is necessary to run the engine indoors, make sure that the exhaust gas is forced outdoors.
Do not perform service work in areas where combustible materials can come in contact with a hot
exhaust system. When working with toxic or flammable materials (such as gasoline and refrigerant),
make sure that the area you work in is well-ventilated.
To avoid getting burned, keep away from hot metal parts such as the radiator, exhaust manifold, tail-
pipe, muffler, etc.
New and used engine oil can be hazardous. Children and pets may be harmed by swallowing new or
used oil. Keep new and used oil and used engine oil filters away from children and pets.
Continuous contact with used engine oil has been found to cause [skin] cancer in laboratory animals.
Brief contact with used oil may irritate skin. To minimize your exposure to used engine oil, wear a
long-sleeve shirt and moisture-proof gloves (such as dish washing gloves) when changing engine
oil. If engine oil contacts your skin, wash thoroughly with soap and water. Launder any clothing or
rags if wet with oil, recycle or properly dispose of used oil and filters.
Make sure the bonnet is fully closed and latched before driving. If it is not, it can fly up unexpectedly
during driving, obstructing your view and resulting in an accident.
CAUTION:
Before staring any service work, cover fenders, seats and
any other parts that are likely to get scratched or stained dur-
ing servicing. Also, be aware that what you wear (e.g. but-
tons) may cause damage to the vehicle’s finish.
When performing service to electrical parts that does not re-
quire use of battery power, disconnect the negative cable of
the battery.

ON-VEHICLE SERVICE
ENGINE VACUUM CHECK
The engine vacuum that develops in the intake line is a good indica-
tor of the condition of the engine. The vacuum checking procedure
is as follows:
1) Warm up engine to normal operating temperature.
2) With engine stopped, remove blind plug hose from intake man-
ifold and connect special tool (vacuum gauge and joint) to va-
cated threaded hole.
Special Tool
(A): 09915-67311
3) Run engine at specified idle speed (see Section 6E), and read
vacuum gauge. Vacuum should be within the following specifi-
cation.
Vacuum specification: 52.6 – 65.8 kPa (40 – 50 cm
.Hg,
15.7 – 19.7 in
.Hg) at specified
idling speed
4) After checking, apply sealant to thread of blind plug and install
it to intake manifold.
OIL PRESSURE CHECK
NOTE:
Prior to checking oil pressure, check the followings.
Oil level in oil pan.
If oil level is low, add oil up to Full level hole on oil level
gauge.
Oil quality.
If oil is discolored, or deteriorated, change it.
For particular oil to be used, refer to the table in Section 0B.
Oil leaks.
If leak is found, repair it.
1) Using special tool (Oil filter wrench), remove oil filter.
2) After removing oil filter, remove oil pressure switch (1) from cylin-
der block.
