GENERAL MAINTENANCE
GENERAL MAINTENANCE

General MaintenanceELS000AL
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 owners can perform the
checks and inspections themselves or they can have their NISSAN dealers do them for a nominal charge.
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.
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. Item Reference page
TiresCheck the pressure with a gauge periodically when at a service station, includ-
ing the spare, and adjust to the specified pressure if necessary. Check carefully
for damage, cuts or excessive wear.—
Windshield wiper
bladesCheck for cracks or wear if not functioning correctly. —
Doors and engine
hoodCheck that all doors, the engine hood, the trunk lid and back door operate prop-
erly. Also ensure that all latches lock securely. Lubricate 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 frequently.BL-4
,BL-8
Tire rotationTires should be rotated every 5,000 km (3,000 miles).MA-38
Item Reference page
LampsMake sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head-
lamp aim.—
Warning lamps and
chimesMake sure that all warning lamps and buzzers/chimes are operating properly. —
Steering wheelCheck that it has the specified play.
Check for changes in the steering conditions, such as excessive free play, hard
steering or strange noises.
Free play: Less than 35 mm (1.38 in)—
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, a dju sters and
retractors) operate properly and smoothly, and are installed securely. Check the
belt webbing for cuts, fraying, wear or damage.SB-3
Item Reference page
Windshield washer
fluidCheck that there is adequate fluid in the tank. —
Engine coolant levelCheck the coolant level when the engine is cold.CO-29

Brake and clutch fluid
levelsMake sure that the brake and clutch fluid levels are between the “MAX” and
“MIN” lines on the reservoir.MA-35
,MA-39
BatteryCheck the fluid level in each cell. It should be between the “MAX” and “MIN”
lines.—

ENGINE MAINTENANCE (QR20DE·QR25DE) PFP:00100
Checking Drive BeltsELS000KA
WARNING:
Be sure to perform when the engine is stopped.
●Make sure that the indicator (single line notch on fixed side) of drive belt auto-tensioner is within the pos-
sible use range (between three line notches on moving side).
NOTE:
●Check the drive belt auto-tensioner indicator (single line notch on fixed side) when the engine is cold.
●When the new drive belt is installed, the indicator (single line notch on fixed side) should be within the
range A.
●Visually check entire belt for wear, damage or cracks.
●If the indicator (single line notch on fixed side) is out of possible use range or belt is damaged, replace the
belt.
Tension AdjustmentELS000K4
Belt tensioning is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Changing Engine CoolantELS000JV
WARNING:
●To avoid being scalded, never change the engine coolant when the engine is hot.
●Wrap a thick cloth around cap and carefully remove the cap. First, turn the cap a quarter of a turn
to release built-up pressure. Then turn the cap all the way.
DRAINING ENGINE COOLANT
1. Open radiator drain plug at the bottom of radiator, and remove
radiator cap.
●Be careful not to allow engine coolant to contact drive belts.
PBIC1234E
PBIC0236E

MA-22
ENGINE MAINTENANCE (QR20DE·QR25DE)
●Replace the radiator cap if there is an abnormality in the negative-pressure valve, or if the open-valve
pressure is outside of the standard values.
CHECKING RADIATOR SYSTEM FOR LEAKS
To check for leakage, apply pressure to the cooling system with a
tester.
WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure engine coolant escaping
from the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
Checking Fuel LinesELS000JX
Inspect fuel lines, filler cap and tank for improper attachment, leaks,
cracks, damage, loose connections, chafing or deterioration. If nec-
essary, repair or replace faulty parts.
Fuel Hose Clamp
CAUTION:
Tighten high-pressure rubber hose clamp so that clamp end is
3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.
Changing Air Cleaner FilterELS000JY
VISCOUS PAPER TYPE
The viscous paper type filter does not need cleaning.
DRY PAPER TYPE
It is necessary to clean the filter or replace it at the recommended intervals, more often under dusty driving
conditions.Testing pressure:
