GENERAL MAINTENANCE
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).
Accelerator pedalCheck the pedal for smooth operation and make sure the pedal does not catch
or require uneven effort. Keep the floor mats away from the pedal. —
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. Be sure to
keep the floor mats away from the pedal. BR-5
,
BR-14
Parking brake Check that the pedal has the proper travel and make sure that the vehicle is
held securely on a fairly steep hill when only the parking brake is applied. PB-3
Automatic transmis-
sion "Park" mecha-
nismCheck that the lock release button on the selector lever operates properly and
smoothly. On a fairly steep hill check that the vehicle is held securely with the
selector lever in the P (Park) position without applying any brakes.

Item Reference page
Windshield washer
fluid Check that there is adequate fluid in the tank. —
Engine coolant level Check the coolant level when the engine is cold. MA-12
, MA-19
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, de-
terioration or loose connections. —
Brake fluid level Make sure that the brake fluid level is between the “MAX” and “MIN” lines on the
reservoir. MA-32

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 re-
quire frequent checks of the battery fluid level. SC-4
Engine drive belts
Make sure that no belt is frayed, worn, cracked or oily. MA-11, MA-19
Engine oil level Check the level on the oil level gauge after parking the vehicle on a level spot
and turning off the engine. MA-15,
MA-22
Power steering fluid
level and lines Check the level on the dipstick with the engine off. Check the lines for improper
attachment, leaks, cracks, etc.
MA-33
Exhaust system
Make sure there are no loose supports, cracks or holes. If the sound of the ex-
haust seems unusual or there is a smell of exhaust fumes, immediately locate
the trouble and correct it. MA-26
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. —

ENGINE MAINTENANCE (VQ35DE ENGINE)
Checking Drive BeltsINFOID:0000000001328900
WARNING:
Be sure to perform when engine is stopped.
1. Inspect belts for cracks, fraying, wear and oil. If necessary, replace.
2. Inspect drive belt deflection or tension at a point on belt midway
between pulleys.
 Inspection should be done only when engine is cold, or over 30 minutes after engine is stopped.
 Measure the belt tension with belt tension gauge (Commercial service tool: BT3373-F or equivalent) (A) at points marked
shown in the figure.
 When measuring the deflection, apply 98 N (10 kg, 22 lb) at
the marked point.
 Adjust if the belt deflection exceeds the limit or if the belt ten- sion is not within specifications.
CAUTION:
• When checking the belt deflect ion or the tension immedi-
ately after installation, first ad just it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust
to the specified value to avo id variation in deflection
between pulleys.
 Tighten idler pulley lock nut by hand and measure the deflection or the tension without loose-
ness.
Belt Deflection and Tension
*: If belt tension gauge cannot be installed at check points shown, check drive belt tension at different location on belt.

ENGINE MAINTENANCE (VQ35DE ENGINE)
 When belt is replaced with a new one, adjust it to value for “New belt” to accommodate for insuffi-
cient adaptability with pulley grooves.
 When deflection or tension of belt being used exceeds “Limit”, adjust it to value for “After adjust-
ment”.
 When checking belt deflection or te nsion immediately after installation, first adjust it to the specified
value. Then, after turning crankshaft two turns or mo re, re-adjust to the specified value to avoid vari-
ation in deflection between pulleys.
 When installing belt, make sure that it is correctly engaged with pulley grooves.
 Keep engine oil, working fluid and engine coolant away from belt and pulley grooves.
 Do not twist or bend belt excessively.
ALTERNATOR AND POWER STEERING OIL PUMP BELT
1. Remove front engine undercover with power tool.
2. Loosen idler pulley lock nut (A) and adjust tension by turning adjusting bolt (B).
 For the specified belt tension, refer to EM-14, "
Checking Drive
Belts".
3. Tighten nut (A).
A/C COMPRESSOR BELT
1. Remove front engine undercover with power tool.
2. Loosen idler pulley lock nut (C) and adjust tension by turning adjusting bolt (D).  For the specified belt tension, refer to EM-14, "
Checking Drive Belts".
3. Tighten nut (C).
Changing Engine CoolantINFOID:0000000001328902
WARNING:
 To avoid being scalded, do not change en gine coolant when the engine is hot.
 Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressu re. Then turn radiator cap all the way.
 Be careful not to allow engine coolant to contact drive belts.

CAUTION:
 After any collision, inspect all seat belt assembli es, including retractors and other attached hard-
wares (I.e. anchor bolt, guide rail set). Nissan recommends to replace all seat belt assemblies in use
during a collision, unless not damaged an d properly operating after minor collision.
Also inspect seat belt assemblies no t in use during a collision, and replace if damaged or improperly
operating.
Seat belt pre-tensioner should be replaced even if the seat belts are not in use during a frontal colli-
sion where the driver and passenger air bags are deployed.
 If any component of seat belt assembl y is questionable, do not repair.
Replace as seat belt assembly.
 If webbing is cut, frayed, or damaged, replace belt assembly.
 Never oil tongue and buckle.
 Use a genuine NISSAN seat belt assembly.
