GENERAL MAINTENANCE
Revision: 2006 December 2006 FX35/FX45
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). 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-
nism Check 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
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-15
, MA-22
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 reservoir. MA-35

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. SC-5
Engine drive belts
Make sure that no belt is frayed, worn, cracked or oily. MA-14, MA-22
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-18,
MA-25
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-37
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-29
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. —

RECOMMENDED FLUIDS AND LUBRICANTSPFP:00000
Fluids and Lubricants NLS00060
*1: For further details, see “SAE Viscosity Number”.
*2: Using automatic transmission fluid other than Genuine NISSAN Matic J ATF will cause deterioration in driveability and
automatic transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new
vehicle limited warranty.
*3: For hot climates, viscosity SAE 90 is suitable for ambient temperatures above 0 °C (32 °F).
*4: DEXRON
TM III/ MERCONTM or equivalent may also be used. Outside the continental United States and Alaska contact an INFINITI
dealer for more information regarding suitable fluids, including recommended brand(s) of DEXRON TM III/ MERCONTM automatic trans-
mission fluid.
*5: For Canada, NISSAN Automatic Transmission Fluid (ATF), DEXRON
TM III/ MERCONTM , or equivalent ATF may also be used.

ENGINE MAINTENANCE (VQ35DE ENGINE)
Revision: 2006 December 2006 FX35/FX45
ENGINE MAINTENANCE (VQ35DE ENGINE)PFP:10001
Checking Drive BeltsNLS00063
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) 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 deflection or the tension immediately after installation, first adjust it to
the specified value. Then, after turning crankshaft two turns or more, re-adjust to the specified
value to avoid 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.
Drive Belts Tension AdjustmentNLS00064
CAUTION:

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 tension immediately after installation, first adjust it to the speci-
fied value. Then, after turning crankshaft two turns or more, re-adjust to the specified value to
avoid variation 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.
