GENERAL INFORMATION 0A-7
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 ªVEHICLE LIFTING
POINTSº 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 dishwashing 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 starting 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.

0B-6 MAINTENANCE AND LUBRICATION
Water pump, generator, power steering and / or A / C
compressor (if equipped) drive belt (J20 engine)
Inspection
1) Disconnect negative cable at battery.
2) Inspect belt for cracks, cuts, deformation, wear and cleanliness.
If any of above conditions are found, replace.
Also, check belt for tension.
Tension indicator ªBº should be the right of indicator ªAº as
shown in figure. If indicator ªBº is found to the left of indicator ªAº,
replace generator belt.
Replacement
Replace belt referring to Section 6H for replacement procedure of
generator drive belt.
Engine cooling fan drive belt (J20 engine)
Inspection
1) Disconnect negative cable at battery.
2) Inspect belt for cracks, cuts, deformation, wear and cleanliness.
If any defect exists, replace. Check belt for tension.
Cooling fan belt tension
ªaº: 5 ± 7 mm (0.20 ± 0.27 in.) deflection under 100 N, 10 kg
or 22 lb pressure.
NOTE:
When replacing belt with a new one, adjust belt deflection
to 4 ± 5 mm (0.16 ± 0.19 in.).
3) If the belt is too tight or too loose, adjust it to specification by ad-
justing cooling fan pulley position.
4) Tighten adjusting bolt and pivot bolt.
5) Connect negative cable at battery.
Replacement
Replace belt referring to Section 6B for replacement procedure of
cooling fan drive belt.
