INSPECTION AFTER REMOVAL
Oil Cooler
Check oil cooler for cracks. Check oil cooler for clogging by blowing compressed air through engine coolant
inlet. If necessary, replace oil cooler assembly.

General MaintenanceELS001BI
General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owner can perform these
checks and inspections or have their INFINITI dealers perform them.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the
vehicle, etc. Item
Reference page
Tires Check the pressure with a gauge at least once a month and always prior to a
long distance trip. Adjust to the specified pressure if necessary. Check carefully
for damage, cuts or excessive wear. —
Wheel lug nuts When checking the tires, make sure no nuts are missing, and check for any
loose nuts. Tighten if necessary. WT-7, "
Rotation"
Windshield
Clean the windshield on a regular basis. Check the windshield at least every six
months for cracks or other damage. Repair as necessary. —
Tire rotation Tires should be rotated every 12,000 km (7,500 miles). WT-7, "
Rotation"
Wheel alignment and
balanceIf the vehicle pulls to either side while driving on a straight and level road, or if
you detect uneven or abnormal tire wear, there may be a need for wheel align-
ment. If the steering wheel or seat vibrates at normal highway speeds, wheel
balancing may be needed. WT-6, "Balancing
Wheels", FSU-6, "Front
Wheel Alignment"
Windshield wiper
blades
Check for cracks or wear if they do not wipe properly.
—
Doors and engine
hood Check that all doors and the engine hood operate smoothly as well as the back
hatch. Also make sure that all latches lock securely. Lubricate if necessary.
Make sure that the secondary latch keeps the hood from opening when the pri-
mary latch is released.
When driving in areas using road salt or other corrosive materials, check lubri-
cation frequently. MA-31, "
Lubricating
Locks, Hinges and Hood
Latches"
Lamps
Make sure that the head lamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head
lamp aim. Clean the head lamps on a regular basis. LT-29, "Aiming Adjust-
ment" for US, LT-46,
"Aiming Adjustment" for
Canada

ponents Inspection"
Windshield wiper and
washerCheck that the wipers and washer operate properly and that the wipers do not
streak.
—
Windshield defroster Check that the air comes out of the defroster outlets properly and in sufficient
quantity when operating the heater or air conditioner. —
Steering wheel Check that it has the specified play. Be sure to check for changes in the steering
condition, such as excessive play, hard steering or strange noises. PS-7, "
CHECKING
STEERING WHEEL
PLAY"
Seats
Check seat position controls such as seat adjusters, seat back recliner, etc. to
make sure they operate smoothly and that all latches lock securely in every
position. Check that the head restraints move up and down smoothly and that
the locks (if equipped) hold securely in all latched positions. Check that the
latches lock securely for folding-down rear seat backs. —
Seat belts Check that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly and are installed securely. Check the
belt webbing for cuts, fraying, wear or damage. SB-11, "

UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically (e.g. each time you check the engine oil or refuel).Brakes
Check that the brake does not pull the vehicle to one side when applied. —
Brake pedal and
booster Check the pedal for smooth operation and make sure it has the proper distance
under it when depressed fully. Check the brake booster function. Keep the floor
mats away from the pedal. ACC-5, "

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,
deterioration or loose connections. —
Brake fluid level Make sure that the brake fluid level is between the “MAX ” and “ MIN” lines on the
reservoirs MA-28
Battery
Check the fluid level in each cell. It should be between the “MAX ” and “MIN ”
lines. Vehicles operated in high temperatures or under severe conditions require
frequent checks of the battery fluid level. —
Engine drive belt Make sure that no belt is frayed, worn, cracked or oily. MA-13
Engine oil levelCheck the level on the dipstick after parking the vehicle on a level spot and turn-
ing off the engine. —
Power steering fluid
level and lines Check the level on the reservoir with the engine off. Check the lines for improper
attachment, leaks, cracks, etc.
MA-29
Automatic transmis-
sion fluid levelCheck the level on the dipstick after putting the selector lever in
“P ” with the
engine idling. MA-22
Exhaust system
Make sure there are no loose supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of exhaust fumes, immediately locate
the trouble and correct it. MA-22
Underbody
The underbody is frequently exposed to corrosive substances such as those
used on icy roads or to control dust. It is very important to remove these sub-
stances, otherwise rust will form on the floor pan, frame, fuel lines and around
the exhaust 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
can easily accumulate. —
Fluid leaks 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 gasoline fumes are evident, check for
the cause and correct it immediately. —

Checking Drive BeltsELS001PG
WARNING:
Be sure to perform when the engine is stopped.
1. Remove air duct and resonator assembly (inlet) when inspecting drive belt.
2. Make sure that indicator (single line notch) of each auto tensioner is within the allowable working range
“A” (between three line notches) as shown.
NOTE:
Check the auto tensioner indication when the engine is cold.
When the new drive belt is installed, the range should be “A” as shown.
The indicator notch is located on the moving side of the auto tensioner.
3. Visually check entire belt for wear, damage or cracks.
4. If the indicator is out of allowable working range or belt is damaged, replace the belt. Refer to EM-13,
"DRIVE BELTS" .
DRIVE BELT TENSION
There is no manual drive belt tension adjustment. The drive belt tension is automatically adjusted by the auto
tensioner.
Changing Engine CoolantELS001PH
WARNING:
To avoid being scalded, never change the coolant when the engine is hot.
Wrap a thick cloth around the cap to carefully remove the cap. First, turn the cap a quarter of a
turn to release any built-up pressure, then push down and turn the cap all the way to remove it.
DRAINING ENGINE COOLANT
1. Turn ignition switch ON and set temperature control lever all the way to HOT position or the highest tem-
perature position. Wait 10 seconds and turn ignition switch OFF.
2. Remove the engine front undercover using power tool.
