1. Perform the following procedure to open
the heater water cock.
ITurn the ignition key from ªOFFº to ªONº.
IMove the heater or air conditioner tem-
perature control dial to the maximum hot
position then turn the ignition key to
ªOFFº.
2. Open the drain valve and radiator cap.
Open the drain plug on the engine block.
3. Open the air release plug to drain the
coolant.4. Flush the cooling system by running fresh
water through the radiator.
5. Close the drain valve and drain plug se-
curely.
6. See the ªTechnical informationº section for
cooling system capacity.
Fill the radiator slowly with the proper mix-
ture of coolant and water. Fill the reservoir
tank slowly up to the ªMAXº level. Then
install the radiator cap and close the air
release plug.
7. Start the engine and warm it up until itreaches normal operating temperature.
Then race the engine 2 or 3 times under no
load.
Watch the coolant temperature gauge for
signs of overheating.
8. Stop the engine. After it completely cools
down, refill the radiator up to the filler
opening. Fill the reservoir tank up the
ªMAXº level.
9. Check the drain valve and drain plug for
any sign of leakage.

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operating
temperature.
3. Turn off the engine.Wait more than 10
minutes for the oil to drain back into the
oil pan.
4. Remove the dipstick and wipe it clean.
Reinsert it all the way.5. Remove the dipstick again and check the
oil level. It should be between the ªHº and
ªLº marks. If the oil level is below the ªLº
mark, remove the oil filler cap and pour
recommended oil through the opening. Do
not overfill.
6. Recheck oil level with dipstick.
IOil level should be checked regularly.
Operating with insufficient amount of
oil can damage the engine, and such
damage is not covered by warranty.IIt is normal to add some oil between
oil changes or during the break-in
period, depending on the severity of
operating conditions.

CHANGING ENGINE OIL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Warm up the engine until it reaches oper-
ating temperature, and then turn it off.
3. Place a large drain pan under the drain
plug.
4. Remove the oil filler cap.
5. Remove the drain plug with a wrench and
completely drain the oil.
If the oil filter is to be changed, remove andreplace it at this time. See ªChanging oil
filterº.
Be careful not to burn yourself, as the
engine oil is hot.
Waste oil must be disposed of properly.
Check your local regulations.
6. Clean and re-install the drain plug and new
washer. Securely tighten the drain plug with
a wrench. Do not use excessive force.
Drain plug tightening torque:
22 to 29 ft-lb (29 to 39 N×m)
7. Refill engine with recommended oil and
install the oil filler cap securely.
See the ªTechnical informationº section for
refill capacity.
8. Start the engine.
Check for leakage around the drain plug.
Correct as required.9. Turn the engine off and wait several min-
utes. Check the oil level with the dipstick.
Add engine oil if necessary.
IProlonged and repeated contact with
used engine oil may cause skin can-
cer.
ITry to avoid direct skin contact with
used oil. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
IKeep used engine oil out of reach of
children.

CHANGING OIL FILTER
1. Park the vehicle on a level surface and
apply the parking brake.
2. Turn the engine off.
3. Loosen the oil filter with an oil filter wrench.
(A specialcap-typewrench will assist with
oil filter removal on models with the V6
engine. This tool can be purchased from
your NISSAN dealer.) Then remove the oil
filter by turning it by hand.
Be careful not to burn yourself, as the
engine oil may be hot.
4. Wipe the engine oil filter mounting surface
with a clean rag.
Be sure to remove any old rubber gasket
remaining on the mounting surface of the
engine.
5. Coat the rubber gasket on the new filter
with engine oil.
6. Screw in the oil filter until a slight resistance
is felt, then tighten an additional 2/3 turn.
7. Start the engine and check for leakage
around the oil filter. Correct as required.
8. Turn the engine off and wait several min-
utes. Check the oil level. Add engine oil if
necessary.
IWhen engine is running, keep hands
and clothing away from any moving
parts such as fan and drive belt.
IAutomatic transmission fluid is poi-
sonous and should be stored care-
fully in marked containers out of the
reach of children.
The fluid level should be checked using the
ªHOTº range (ªLº & ªHº marks) on the dipstick

at fluid temperatures between 122 and 176ÉF
(50 and 80ÉC) after the vehicle has been
driven approximately 5 minutes in urban areas
after the engine is warmed up. The level can
be checked at fluid temperatures between 86
and 122ÉF (30 and 50ÉC) using the ªCOLDº
range on the dipstick for reference, after the
engine is warmed up but before driving. How-
ever, the fluid level must be rechecked using
the ªHOTº range.
1. Park the vehicle on a level surface and set
the parking brake.
2. Start the engine and then move the selector
lever through each gear range, ending in
ªPº.
3. Check the fluid level with the engine idling.
If the vehicle has been driven for a long
time at high speeds, or in city traffic in hot
weather, or if it is being used to pull a
trailer, the fluid level cannot be read accu-
rately. You should wait until the fluid has
cooled down (about 30 minutes).
4. Remove the dipstick and wipe it clean with
lint-free paper.
5. Re-insert the dipstick into the charging pipe
as far as it will go.
6. Remove the dipstick and note the reading.If the level is on the low side of either range,
add fluid to the charging pipe.
IDo not overfill.
IUse Nissan Matic ªDº (Continental
U.S. and Alaska) or Genuine Nissan
Automatic Transmission Fluid
(Canada).

Type A
Add fluid when the low washer fluid warning
light comes on. Add a washer solvent to the
water for better cleaning. In the winter season,
add a windshield washer anti-freeze. Follow
the manufacturer's instructions for the mixture
ratio.
Type B
To check the fluid level, use your finger to plug
the center hole of the cap/tube assembly (as
shown above), then remove it from the tank. If
there is no fluid in the tube, add fluid.Add a washer solvent to the water for better
cleaning. In the winter season, add a wind-
shield washer anti-freeze. Follow the manufac-
turer's instructions for the mixture ratio.
Do not substitute engine anti-freeze
coolant for window washer solution.
This may result in damage to the paint.
Anti-freeze is poisonous and should be
stored carefully marked containers out
of the reach of children.

IKeep the battery surface clean and dry. Any
corrosion should be washed off with a
solution of baking soda and water.
IMake certain the terminal connections are
clean and securely tightened.
IIf the vehicle is not to be used for 30 days or
longer, disconnect the ªþº negative battery
terminal cable to prevent discharge.
Do not expose the battery to flames or
electrical sparks. Hydrogen gas gener-
ated by battery action is explosive. Do
not allow battery fluid to contact your
skin, eyes, fabrics, or painted surfaces.
After touching a battery or battery cap,
do not touch or rub your eyes. Thor-
oughly wash your hands. If the acid
contacts your eyes, skin or clothing,
immediately flush with water for at least
15 minutes and seek medical attention.
JUMP STARTING
If jump starting is necessary, see the ªIn case
of emergencyº section. If the engine does not
start by jump starting, the battery may have tobe replaced. Contact a NISSAN dealer.
Check the fluid level in each cell. It should be
between the MAX. and MIN. lines.
If it is necessary to add fluid, add only distilled
water to bring the level to the indicator in each
filler opening.Do not overfill.
1. Remove the cell plugs using a suitable tool.
2. Add distilled water up to the MAX. level.
3. Tighten cell plugs.
