NISSAN ALTIMA 2005 L31 / 3.G Owners Manual

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
cPark the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. For manual transmission
models, move the shift lever to N (Neu-
tral) . For automatic transmission mod-
els, move the selector lever to P (Park) .
c Be sure the ignition key is in the OFF or
LOCK position when performing any
parts replacement or repairs.
c Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
c Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
c
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition key is in the OFF position and the
engine is not running. To avoid injury, always disconnect the negative battery
cable before working near the fan.
c
If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.
c It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
c Always wear eye protection whenever
you work on your vehicle.
c If you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
c Never get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
c Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
c On gasoline engine models with the
multiport fuel injection (MFI) system,
the fuel filter or fuel lines should be serviced by a NISSAN dealer because
the fuel lines are under high pressure
even when the engine is off.
CAUTION
c
Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
c Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
This “Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.
A genuine NISSAN service manual is also avail-
able. See “Owner’s Manual/Service Manual or-
der information” in the “Technical and consumer
information” section of this manual.
You should be aware that incomplete or improper
servicing may result in operating difficulties or
excessive emissions, and could affect warranty
coverage. If in doubt about any servicing,
have it done by a NISSAN dealer.

The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze cool-
ant solution. The anti-freeze solution contains
rust and corrosion inhibitors; therefore, additional
engine cooling system additives are not neces-
sary.
WARNING
cNever remove the radiator cap when the
engine is hot. Serious burns could be
caused by high pressure fluid escaping
from the radiator.
c The radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine damage, use only a genuine
NISSAN radiator cap.

CAUTION
When adding or replacing coolant, be sure
to use only a Genuine NISSAN Long Life
Antifreeze/Coolant (green) or equivalent
with the proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled
water. The use of other types of coolant
solutions or coolant colors, such as or-
ange, may damage the engine cooling
system.
CHECKING ENGINE COOLANT
LEVEL
Check the coolant level in the reservoir when
the engine is cold. If the coolant level is below
the MIN level, add coolant to the MAX level. If the
reservoir is empty, check the coolant level in the
radiator when the engine 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 a NISSAN
dealer.

CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine coolant.
The service procedure can be found in the
NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
cTo avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
c Never remove the radiator cap when the
engine is hot. Serious burns could be
caused by high pressure fluid escaping
from the radiator.
c Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
c Keep coolant out of the reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.

5. Remove the dipstick again and check the oillevel. It should be between the H (High) and
L (Low) marks
sB. This is the normal oper-
ating oil level range. If the oil level is below
the L (Low) mark
sA, remove the oil filler cap
and pour recommended oil through the
opening. Do not overfill
sC. 6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the severity
of operating conditions.CAUTION
Oil level should be checked regularly. Op-
erating the engine with an insufficient
amount of oil can damage the engine, and
such damage is not covered by warranty.
CHANGING ENGINE OIL
1. Park the vehicle on a level surface and apply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature, then turn it off.
3. Remove the oil filler cap by turning it coun- terclockwise.

5. Remove the drain plug with a wrench byturning it counterclockwise and completely
drain the oil.
If the oil filter is to be changed, remove and
replace it at this time. See “Changing engine
oil filter” later in this section.
WARNING
c Prolonged and repeated contact with
used engine oil may cause skin cancer. c
Try to avoid direct skin contact with
used oil. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
c Keep used engine oil out of reach of
children.
CAUTION
Be careful not to burn yourself. The engine
oil may be hot.
c Waste oil must be disposed of prop-
erly.
c Check your local regulations.
6. Clean and reinstall the drain plug and a new washer. Securely tighten the drain plug with
a wrench. Do not use excessive force.
Drain plug tightening torque: 22 - 29 ft-lb (29 - 39 N·m)
7. Refill engine with recommended oil through the oil filler opening, then install the oil filler
cap securely.
See “Capacities and recommended
fuel/lubricants” in the “Technical and con-
sumer information” section of this manual for
drain and refill capacity. The drain and refill capacity depends on the
oil temperature and drain time. Use these
specifications for reference only. Always use
the dipstick to determine when the proper
amount of oil is in the engine.
8. Start the engine. Check for leakage around the drain plug and oil filter. Correct as re-
quired.
9. Turn the engine off and wait more than 10 minutes. Check the oil level with the dipstick.
