cooling NISSAN MAXIMA 2003 A33 / 5.G User Guide

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to yourself
or damage to the vehicle. The following are
general precautions which should be closely
observed.
WARNING
IPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
N (Neutral) position. For an automatic
transmission, move the selector lever
to P (Park) position.
IBe sure the ignition key is OFF or
LOCK when performing any parts re-
placement or repairs.
IYour vehicle is equipped with an au-
tomatic 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 run-
ning. To avoid injury, always discon-nect the negative battery cable before
working near the fan.
IIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other moving
parts.
IIt is advisable to secure or remove
any loose clothing and any jewelry,
such as rings, watches, etc. before
working on your vehicle.
IAlways wear eye protection when-
ever you work on your vehicle.
IIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
INever get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
IKeep smoking materials, flame and
sparks away from fuel and the bat-tery.
IOn 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
IDo not work under the hood while the
engine is hot. Turn off the engine and
wait until it cools down.
INever connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition
key is on.
INever leave the engine or the auto-
matic transmission related compo-
nent harness connector discon-
nected while the ignition key is on.
IAvoid direct contact with used engine
oil and coolant. Improperly disposed

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze solu-
tion contains rust and corrosion inhibitors,
therefore additional cooling system additives
are not necessary.
CAUTION
When adding or replacing coolant, be
sure to use only a genuine NISSAN anti-
freeze coolant or equivalent with the
proper mixture ratio of 50% anti-freeze
and 50% demineralized water/distilled
water. The use of other types of coolant
solutions may damage your engine
cooling system.Outside temperature

WARNING
INever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator. Wait
until the engine and radiator cool
down.

ª6. In case of emergencyº section.
IThe radiator is equipped with a pres-
sure cap. To prevent engine damage,
use only a genuine NISSAN radiator
cap.
CHECKING ENGINE COOLANT
LEVELCheck the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below MIN, add coolant up to the MAX level. If
the reservoir tank is empty, check the coolant
level in the radiatorwhen 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 tank up to the
MAX level.
If the engine cooling system frequently
requires coolant, have it checked by your
NISSAN dealer.

CHANGING ENGINE COOLANTIMajor cooling system repairs should be
performed by your NISSAN dealer. The
service procedures can be found in the
appropriate NISSAN Service Manual.IImproper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
ITo avoid being scalded, never change
the coolant when the engine is hot.
INever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
IAvoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
IKeep coolant out of reach of children
and pets.
1. Perform the following procedure to open
the heater water cock.
ITurn the ignition key from OFF to ON.
IMove the heater or air conditioner tem-
perature control dial to the maximum hot
position then turn the ignition key to
OFF.
2. Open radiator drain valve at the bottom ofradiator, and remove radiator filler cap.
IBe careful not to allow coolant to con-
tact drive belts.
IWaste coolant must be disposed of
properly. Check your local regulations.
3. Close the radiator drain valve securely after
the coolant is drained.
4. Fill the radiator slowly with the proper mix-
ture of anti-freeze solution and demineral-
ized water/distilled water. Fill the reservoir
tank up to the MAX level. Then install the
radiator filler cap.
5. 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 engine coolant temperature
gauge for signs of overheating.
6. 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. Check the drain valve for any
sign of leakage.
7. Recheck the coolant level after the vehicle
has been driven for a day.

CHANGING ENGINE OIL FILTER1. 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.
(Depending on the engine model, a special
cap typewrench may be required. See
your NISSAN dealer if in doubt.) Remove
the oil filter by turning it by hand.
CAUTION
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 clean engine oil.
6. Screw in the oil filter until a slight resistance
is felt, then tighten additionally more than
2/3 turn.
Oil filter tightening torque:
10.85 to 15.19 ft-lb
(14.7 to 20.6 N×m)
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.
WARNING
IWhen engine is running, keep hands,
jewelry and clothing away from any
moving parts such as cooling 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.
