PERIODIC MAINTENANCE
NOTE:
lMaintenance items with “ ” should be performed more frequently according to “Maintenance Under Severe Driving
Conditions”.
l(1) If valve noise increases, check valve clearance.
l(2) Never use CG-4 oil.
l(3) Oil filter element assembly and O-ring seal are replacement parts.
l(4) First replace at 100,000 Km (60,000 miles), then every 60,000Km (36,000 miles). After first replacement, perform "I"
(checking the mixture ratio and correcting the mixture ratio if necessary) at the middle of replacement interval.
l(5) If engine power decreases, black exhaust smoke is emitted or engine noise increases, perform this maintenance item.

CHECKING COOLING SYSTEM FOR LEAKS
lTo check for leakage, apply pressure to the cooling system with
atester.
WA RN ING:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
Checking Fuel LinesELS000AQ
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.
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.

Checking EVAP Vapor LinesELS000AV
1. Visually inspect EVAP vapor lines for improper attachment and for cracks, damage, loose connections,
chafing and deterioration.
2. Inspect fuel tank filler cap vacuum relief valve for clogging, sticking, etc.
Refer toEC-372, "
EVAPORATIVE EMISSION SYSTEM"(With E-OBD models) orEC-647, "EVAPORA-
TIVE EMISSION SYSTEM"(Without E-OBD models).

tive-pressure valve, or if the open-valve pressure is outside of
the standard values.

PRECAUTIONS
PRECAUTIONS
PFP:00001
CautionEDS00060
Observe the following precautions when disassembling and servicing drive shaft.
lPerform work in a location which is as dust-free and dirt-free as possible.
lBefore disassembling and servicing, clean the outside of parts.
lThe disassembly and service location must be clean. Care must be taken to prevent parts from becoming
dirty and to prevent the entry of foreign objects.
lDisassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean
cover must be placed over parts.
lPaper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adher-
ing to parts.
lDisassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by
blowing with air or wiping with paper shop cloths.
Precautions for Brake SystemEDS0 00 I2
lWhen installing rubber parts, final tightening must be carried out
under unladen condition* with tires on ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
lUse flare nut wrench when removing or installing brake tubes.
lAfter installing removed suspension parts, check wheel align-
ment and adjust if necessary.
lAlways torque brake lines when installing.

PRECAUTIONS
PRECAUTIONS
PFP:00001
CautionEDS00056
lBefore starting diagnosis of the vehicle, understand symptoms well. Perform correct and systematic oper-
ations.
lCheck for the correct installation status prior to removal or disassembly. When mating marks are required,
be sure they do not interfere with the function of the parts they are applied to.
lCarry out an overhaul in a clean work place. Using a dust proof room is recommended.
lBefore disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of
the unit, preventing them from entering into the unit during disassembly or assembly.
lCheck appearance of the disassembled parts for damage, deformation, and abnormal wear. If a malfunc-
tion is detected, replace it with a new one.
lNormally replace lock pins, oil seals, and bearings with new ones every time they are removed.
lIn principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
lClean and flush the parts sufficiently and blow them dry.
lBe careful not to damage the sliding surfaces and mating surfaces.
lWhen applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
lAlways use shop paper for cleaning the inside of components.
lAvoid using cotton gloves or a shop cloth to prevent entering of lint.
lDuring assembly, observe the specified tightening torque, and apply new differential oil, Vaseline, or Nis-
san MP Special Grease No. 2, as specified for each vehicle, when necessary.
lDo not reuse drained oil. Discard waste oil after oil changes or part treatment in accordance with local
laws and regulations.
