INSPECTION
1. Check for badly rusted or corroded body assembly and vane.
2. Check for rough operation due to excessive end play.
3. Check fan coupling for rough operation, wobbling, oil leakage
or bent bimetal.
The water pump and fan coupling cannot be disassembled
and should be replaced as a unit.

PRE-DELIVERY INSPECTION ITEMS
MA-3

General maintenance includes those items which should be checked during the normal day-to-day opera-
tion of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can per-
form the checks and inspections themselves or they can have their NISSAN dealers do them.
Item Reference pages
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise
specified.
TiresCheck the pressure with a gauge periodically when at a service station, including the
spare, and adjust to the specified pressure if necessary. Check carefully for damage, cuts or
excessive wear.Ð
Windshield wiper bladesCheck for cracks or wear if they do not wipe properly. Ð
Doors and engine hoodCheck that all doors, the engine hood, the trunk lid and back door
operate properly. Also ensure that all latches lock securely. Lubricate hinges, latches, rollers and
links if necessary. Make sure that the secondary latch keeps the hood from opening when the
primary latch is released.
When driving in areas using road salt or other corrosive materials, check for lubrication fre-
quently.MA-39
Tire rotationTires should be rotated every 10,000 km (6,000 miles) for 2WD models and every
5,000 km (3,000 miles) for 4WD models.MA-35
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the vehicle, etc.
LightsMake sure that the headlights, stop lights, tail lights, turn signal lights, and other lights
are all operating properly and installed securely. Also check headlight aim.Ð
Warning lights and chimesMake sure that all warning lights and chimes are operating prop-
erly.Ð
Steering wheelCheck for change in the steering conditions, such as excessive free play, hard
steering or strange noises.
Free play: Less than 35 mm (1.38 in)Ð
Seat beltsCheck 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.MA-40
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.
Windshield washer fluidCheck that there is adequate fluid in the tank. Ð
Engine coolant levelCheck the coolant level when the engine is cold. MA-16, 25
Engine oil levelCheck the level after parking the vehicle on a level spot and turning off the
engine.MA-19, 24
Brake and clutch fluid levelMake sure that the brake and clutch fluid levels are between the
``MAX'' and ``MIN'' lines on the reservoir.MA-32, 35
BatteryCheck the fluid level in each cell. It should be between the ``MAX'' and ``MIN'' lines. Ð
