belt INFINITI G35 2003 Workshop Manual

CHANGING ENGINE COOLANT O Major cooling system repairs should be
performed by your INFINITI retailer. The
service procedures can be found in the
appropriate INFINITI Service Manual. O Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING O To avoid being scalded, never change
the coolant when the engine is hot.
O Never remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
O Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
O Keep coolant out of reach of children
and pets.
1. Open radiator drain plug at the bottom of
radiator, and remove radiator filler cap.
O Be careful not to allow coolant to con-
tact drive belts.
O Waste coolant must be disposed of
properly. Check your local regulations.
2. Close the radiator drain plug securely after
the coolant is drained. 3. 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.
4. 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 tempera-
ture gauge for signs of overheating.
5. 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 plug for any
sign of leakage.
6. Recheck the coolant level after the vehicle
has been driven for a day.SDI0114

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.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
1. Remove the cell plugs.
2. Add distilled water up to the MAX level.
3. Tighten cell plugs. JUMP STARTING If jump starting is necessary, see ªJump start-
ingº in the ª6. In case of emergencyº section. If
the engine does not start by jump starting, the

unexpectedly.
1. Visually inspect each belt for signs of un-
usual wear, cuts, fraying, oil adhesion or
looseness. If the belt is in poor condition or
loose, have it replaced or adjusted by your
INFINITI retailer.
2. Have the belts checked regularly for condi-
tion and tension in accordance with the
maintenance schedule in this manual.
WARNING Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION Be sure to use the correct socket to
remove the spark plugs. An incorrect
socket can damage the spark plugs.
REPLACING SPARK PLUGS If replacement is required, see your INFINITI
retailer for servicing.
Platinum-tipped spark plugs It is not necessary to replace the platinum-
tipped spark plugs as frequently as the con-
ventional type spark plugs since they will last
much longer. Follow the maintenance sched-
ule but, do not reuse them by cleaning or
regapping.
Always replace with recommended
platinum-tipped spark plugs. SDI0145

tor is visible, the tire should be re-
placed.
O Improper service for a spare tire may
result in serious personal injury. If it
is necessary to repair the spare tire,
contact your INFINITI retailer.
O For additional information regarding
tires, refer to ªImportant Tire Safety
Informationº (US) or ªTire Safety In-
formationº (Canada) in the INFINITI
Warranty Information Booklet.
Replacing wheels and tires When replacing a tire, use the same size,
speed rating and load carrying capacity as
originally equipped. See ªSpecificationsº in the
ª10. Technical and consumer informationº sec-
tion for recommended types and sizes of tires
and wheels.
WARNINGO The use of tires other than those
recommended or the mixed use of tires of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,
braking, handling, ground clearance,
body-to-tire clearance, tire chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.
O If the wheels are changed for any
reason, always replace with wheels
which have the same offset dimen-
sion. Wheels of a different offset
could cause early tire wear, possibly
degraded vehicle handling character-
istics and/or interference with the
brake discs. Such interference can
lead to decreased braking efficiency
and/or early brake pad wear.
O Do not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without
warning. O The use of retread tires is not recom-
mended.
O For additional information regarding
tires, refer to ªImportant Tire Safety
Informationº (US) or ªTire Safety In-
formationº (Canada) in the INFINITI
Warranty Information Booklet.
Wheel balance Unbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore, they
should be balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balancing
the rear wheels on the vehicle could lead to
transmission damage.
For additional information regarding tires, refer
to ªImportant Tire Safety Informationº (US) or
ªTire Safety Informationº (Canada) in the
INFINITI Warranty Information Booklet.
Care of wheels O Wash the wheels when washing the vehicle
to maintain their appearance.
O Clean the inner side of the wheels when the Do-it-yourself

parking brake applied.
Automatic transmission P (Park) mecha-
nism: On a fairly steep hill check that your
vehicle is held securely with the selector lever in the P (Park) position without applying any
brakes.
Under the hood and vehicle The maintenance items listed here should be
checked periodically (For example, each time
you check the engine oil or refuel).
Windshield washer fluid*: Check that there
is adequate fluid in the tank.
Engine coolant level*: Check the coolant
level when the engine is cold.
Radiator and hoses: 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, deformation, dete-
rioration or loose connections.
Brake and clutch fluid level*: Make sure that
the brake and clutch fluid level is between the
MAX and MIN lines on the reservoir.

EXPLANATION OF MAINTENANCE
ITEMS Additional information on the following
items with ª*º is found in the ª8. Do-it-
yourselfº section.
Emission control system
maintenance Drive belts*: Check drive belts for wear, fray-
ing or cracking and also for proper tension.
Replace the drive belts if found damaged.
Air cleaner filter: Under normal driving con-
ditions, the air cleaner filter should be replaced
in accordance with the maintenance schedule.
However, driving the vehicle in dusty areas
may cause more rapid clogging of the element.
Consequently, the element may have to be
replaced more frequently.
EVAP vapor lines: Check vapor lines and
connections for failure or looseness. If leaks
are found, replace them.
Fuel lines: Check the fuel hoses, piping and
connections for leaks, looseness or deteriora-
tion. Replace any parts if they are damaged.
Engine coolant*: Drain and flush the cooling
system.
Engine oil & oil filter*: Under normal driving conditions, the engine oil and oil filter should
be replaced in accordance with the mainte-
nance schedule. However, under severe driv-
ing conditions, they may have to be replaced
more frequently.
Spark plugs*: Replace with new plugs having
the correct heat range.
Chassis and body maintenance Brake lines & cables: Check the brake lines
and hoses (including brake booster vacuum
hoses, connections & check valve) and park-
ing brake cables for proper attachment, leaks,
cracks, chafing, abrasion, deterioration, etc.
Brake pads & rotors: Check these and the
other neighboring brake components for wear,
deterioration and leaks. Under severe driving
conditions, they may have to be inspected
more frequently.
Automatic transmission fluid*: Using auto-
matic transmission fluid other than Genuine
Nissan ATF Matic Fluid J will cause deteriora-
tion in driveability and automatic transmission
durability, and may damage the automatic
transmission, which is not covered by the
INFINITI new vehicle limited warranty. If
checking or replacement is required, we rec-
ommend your INFINITI retailer for servicing.
Under severe driving conditions, the fluid should be replaced at the specified interval.
Manual transmission oil & differential gear
oil*: Check the oil level and visually inspect for
signs of leakage.
Under severe driving conditions, the oil should
be replaced at the specified interval.
Steering gear & linkage, axle & suspension
parts: Check for damage, looseness and leak-
age of oil or grease. Under severe driving
conditions, more frequent inspection should be
performed.
Exhaust system: Visually check the exhaust
pipes, muffler, and hangers for proper attach-
ment, leaks, cracks, chafing, abrasion, dete-
rioration, etc. Under severe driving conditions,
inspection should be performed more fre-
quently.
In-cabin microfilter: Under normal condi-
tions, this microfilter should be replaced in
accordance with the maintenance schedule.
However, in some situations, the microfilter
may clog more rapidly (depending on the air
conditioner's working environment). If this hap-
pens, the air flow may decrease, or the win-
dows may fog up easily when the air condi-
tioner is in use, the microfilter should be
replaced immediately at your INFINITI retailer.

7. Install the license plate bracket with screws.
8. Install the license plate with bolts that are
no longer than 0.55 in (14 mm).
WARNING O It is extremely dangerous to ride in a
cargo area inside of a vehicle. In a
collision, people riding in these areas
are more likely to be seriously injured
or killed
O Do not allow people to ride in any
area of your vehicle that is not
equipped with seats and seat belts.
O Be sure everyone in your vehicle is in
a seat and using a seat belt properly.
TERMS It is important to familiarize yourself with the
following terms before loading your vehicle:
O Curb Weight (actual weight of your vehicle)
- vehicle weight including: standard and
optional equipment, fluids, emergency
tools, and spare tire assembly. This weight
does not include passengers and cargo.
O GVW (Gross Vehicle Weight) - curb weight
plus the combined weight of passengers
and cargo. O GVWR (Gross Vehicle Weight Rating) -
maximum total weight (load) limit specified
for the vehicle.
O GAWR (Gross Axle Weight Rating) - maxi-
mum weight (load) limit specified for the
front or rear axle.
DETERMINING VEHICLE LOAD
CAPACITY The load capacity of this vehicle is determined
by weight, not by available cargo space. For
example, a luggage rack, bike carrier, cartop
carrier or similar equipment does not increase
load carrying capacity of your vehicle.
To determine vehicle load capacity:
Vehicle weight can be determined by using a
commercial-grade scale, found at places such
as a truck stop, gravel quarry, grain elevator,
or a scrap metal recycling facility.
1. Determine the curb weight of your vehicle.
2. Compare the curb weight amount to the
GVWR specified for your vehicle to deter-
mine how much more weight your vehicle
can carry.
3. After loading (cargo and passengers), re-
weigh your vehicle to determine if either
GVWR or GAWR for your vehicle is ex-VEHICLE LOADING
