1997 NISSAN ALTIMA engine coolant

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze so-
lution contains rust and corrosion inhibitors,
therefore additional cooling system addi-
tives are not necessary.
CAUTION
When adding or replacing coolant, be
sure to use only an ethylene glycol
anti-freeze with the proper mixture ratio
of 50% anti-freeze and 50% distilled
water. The use of other types of coolant
solutions may damage your cooling
system.

WARNING
cNever remove the radiator cap when
the engine is hot. Wait until the en-
gine and radiator cool down. Serious
burns could be caused by high pres-
sure fluid escaping from the radia-
tor. See precautions in ``If your ve-
hicle overheats,'' found in the ``In
case of emergency'' section.
cThe radiator is equipped with a pres-
sure cap. Use a genuine NISSAN cap
or its equivalent when replacement
is required.
CHECKING ENGINE COOLANT
LEVEL
With coolant reservoir
Check the coolant level in the reservoir
when the engine is cold. If the coolant level
is below MIN, add coolant up to the MAX
level. If the reservoir is empty, check the
coolant level in the radiatorwhen the en-
gine is cold.If there is insufficient coolant
in the radiator, fill the radiator with coolant
up to the filler opening and also add it to the
reservoir up to the MAX level.

If the cooling system frequently requires
coolant, have it checked by your NISSAN
dealer.
CHANGING ENGINE COOLANT
cMajor cooling system repairs should be
performed by your NISSAN dealer. The
service procedures can be found in the
appropriate NISSAN Service Manual.cImproper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
cTo avoid the danger of being
scalded, never change the coolant
when the engine is hot.
cNever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
1. Perform the following procedure to open
the heater water cock:
cAutomatic air conditioner
a. Turn ignition switch from OFF to ON.
b.
Within 5 seconds after ignition switch is
turned ON, press the automatic heater
and air conditioner OFF switch for at least
5 seconds. At this time, AUTO, ECON,
88ÉF and
appear in the display.
c. Press(HOT) switch 3 times.
d. Press
(defrost) switch 2 times.
e. Make sure that the display indicates 43.

f. Wait 10 seconds before turning ignition
switch OFF.
cManual air conditioning
a. Turn the ignition switch ON and set the
temperature control lever to the maxi-
mum hot position. Wait 10 seconds, then
turn the switch OFF.
2. Open the radiator drain plug. Open the
drain plug on the engine water pipe.
3. Open the radiator cap to drain the cool-
ant.
4. Flush the cooling system by running
fresh water through the radiator.
5. Close the radiator drain plug and the
drain plug on the engine water pipe se-
curely.
6. See the ``Technical and consumer infor-
mation'' section for cooling system ca-
pacity. Fill the radiator slowly with the
proper mixture of coolant and water. Fill
the reservoir tank up to the MAX level.
7. Open and close the air release plug to
release air. Then fill the radiator again
and install the radiator cap.8. Start the engine and warm it up until it
reaches normal operating temperature.
Then race the engine 2 or 3 times under
no load. Watch the coolant temperature
gauge for signs of overheating.
9. Stop the engine. After it completely cools
down, refill the radiator up to the filler
opening. Fill the reservoir tank up to the
MAX level.
10. Open and close the air release plug to
release air. Then fill the radiator again
and install the radiator cap.11. Check the radiator drain plug and the
drain plug on the engine water pipe for
any sign of leakage, tighten if neces-
sary.

Check the clutch fluid level in the reservoir
(manual transmission only). If the fluid level
is below the MIN line, addDOT 3fluid up the
MAX line. If fluid must be added frequently,
the system should be thoroughly checked
by your NISSAN dealer.
For further brake and clutch fluid specifica-
tion information, refer to ``capacities and
recommended fuel/lubricants'' in the ``Tech-
nical and consumer information'' section of
this manual.
WARNING
Use only new fluid. Old, inferior, or
contaminated fluid may damage the
brake and clutch systems. The use of
improper fluids can damage the brake
system and affect the vehicle's stop-
ping ability.
CAUTION
Do not spill the fluid on painted sur-
faces. This will damage the paint. If
fluid is spilled, wash with water.
Canada Only
Add fluid when the low washer fluid warning
light comes on. Add a washer solvent to the
water for better cleaning. In the winter sea-
son, add a windshield washer anti-freeze.
Follow the manufacturer's instructions for
the mixture ratio.
CAUTION
Do not substitute engine anti-freeze
coolant for windshield washer solution.
This may result in damage to the paint.

HEADLIGHT AIMING
ADJUSTMENT
Before performing aiming adjustment, make
sure of the following:
a. Keep all of the tires inflated to the correct
pressure.
b. Place the vehicle on level ground.
c. See that the vehicle is unloaded (except
for full levels of coolant, engine oil and
fuel, and spare tire, jack, and tools).
Have the driver or an equivalent weight
placed in the driver's seat.
Low beam
1. Open the hood.
2. Adjust the vertical indicator by turning the
adjusting screw with a Phillips screw-
driver. The bubble in the gauge should
be centered on the ``0'' mark.3. Adjust the horizontal indicator by turning
the adjusting screw with a Phillips screw-
driver.
The inner red line with the ``0'' mark
should align with the indicator line. Never
turn screw
sAas indicated in earlier

Automatic transmission ``Park'' mecha-
nismÐ On a fairly steep hill check that your
vehicle is held securely with the gearshift
lever in the P position without applying any
brakes.
UNDER THE HOOD AND
VEHICLE
The maintenance items listed here should
be checked periodically, such as each time
you check the engine oil or refuel.
Additional information on the items
marked with ª*º can be found in the
ªDo-It-Yourself operationsº section.
Windshield washer fluid*Ð Check that
there is adequate fluid in the tank.
Engine coolant level*Ð Check the cool-
ant level when the engine is cold.
Radiator and hosesÐ Check the front of
the radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, de-
formation, rot or loose connections.
Brake and clutch fluid levels*Ð Make
sure that the brake and clutch fluid level is
between the MAX and MIN lines on the
reservoir.Battery*Ð Check the fluid level in each
cell. It should be between the MAX and MIN
lines.
Engine drive belts*Ð Make sure that no
belt is frayed, worn, cracked or oily.
Engine oil level*Ð Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait a few minutes
for the oil to drain back into the oil pan.
Power steering fluid level* and linesÐ
Check the level when the fluid is cold and
the engine is turned off. Check the lines for
proper attachment, leaks, cracks, etc.
Automatic transmission fluid level*Ð
Check the level after putting the shift lever in
P with the engine idling.
Exhaust systemÐ Make sure there are no
cracks, holes, loose joints or supports. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected by
a qualified individual. (See the carbon mon-
oxide warning in the ``Starting and driving''
section.)
UnderbodyÐ The underbody is frequently
exposed to corrosive substances such asthose used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust forms on the floor
pan, frame, fuel lines and around the ex-
haust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean
those areas where mud and dirt may accu-
mulate. See the ``Appearance and interior
care'' section for additional information.
Fluid leaksÐ Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.
