Perform this step when removing water pipe.
3. Remove oil filter. Refer to LU-28, "
OIL FILTER" .
CAUTION:
Do not spill engine oil on drive belts.
4. Disconnect water hoses from oil cooler.

When removing oil cooler only, pinching water hoses near oil cooler to prevent engine coolant spilling.
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on the drive belt.
5. Remove connector bolt, and remove oil cooler. CAUTION:
Do not spill engine oil to rubber parts such as drive belts and engine mounting insulator.

6. Remove water pipe, as necessary.
INSPECTION AFTER REMOVAL
Oil Cooler
Check oil cooler for cracks. Check oil cooler for clogging by blowing through engine coolant inlet. If necessary,
replace oil cooler.
Relief Valve
Check relief valve for movement, cracks and breaks by pushing the ball. If replacement is necessary, remove
relief valve by prying it out with suitable tool. Install a new valve in place by tapping it.
INSTALLATION
Note the following, and install in the reverse order of removal.

Make sure that no foreign objects are adhering to the installation planes of oil cooler or oil pan.

Tighten connector bolt after aligning stopper on the oil pan side
with protrusion of oil cooler.
INSPECTION AFTER INSTALLATION
1. Make sure level of engine oil and engine coolant, and adjust engine oil and engine coolant. Refer to LU-
25, "ENGINE OIL" and CO-37, "ENGINE COOLANT" .
2. Start engine, and make sure there is no leak of engine oil or engine coolant.
3. Stop engine and wait for 15 minutes.
4. Check the engine oil level and the engine coolant level again. Refer to LU-25, "
ENGINE OIL" and CO-37,
"ENGINE COOLANT" .

GENERAL MAINTENANCE
Revision: 2005 July 2005 FX
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-2
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, "
CHECKING
ELECTROLYTE LEVEL"
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. —

PERIODIC MAINTENANCE
Revision: 2005 July 2005 FX
NOTE:
(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) fl uid (A/T, trans-
fer)/oil at every 30,000 miles (48,000 km) or 24 months. 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 transmis-
sion, which is not covered by the INFINITI new vehicle limited warranty.
(2) Refer to “Tire rotation” under the “GENERAL MAINTENANCE” heading earlier in this section.
