Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before working
on the vehicle.
These operations should be done on a level surface.
When removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.
Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.
Battery posts, terminals and related accessories contain lead
and lead compounds. Wash hands after handling.
To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
Dispose of or recycle drained oil or the solvent used for cleaning
parts in an appropriate manner.
Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel
spray and possibly a fire.
Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.
Replace inner and outer races of tapered roller bearings and needle bearings as a set.
Arrange the disassembled parts in accordance with their assembled locations and sequence.
Do not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.
Use only the fluids and lubricants specified in this manual.
Use approved bonding agent, sealants or their equivalents when required.
Use hand tools, power tools (disassembly only) and recom-
mended special tools where specified for safe and efficient ser-
vice repairs.
When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.

WINDSHIELD GLASS
Revision: 2006 January2006 M35/M45
4. Remove the cowl top cover. Refer to EI-18, "COWL TOP" .
5. Remove roof side molding. Refer to EI-25, "
ROOF SIDE MOLDING" .
6. Apply a protective tape around the windshield glass to protect the painted surface from damage.
After removing moldings, remove glass using piano wire or power cutting tool A and an inflatable pump bag B.
If a windshield glass is to be reused, mark the body and the glass with mating marks.
WA R N I N G :
When cutting the glass from the vehicle, always wear safety glasses and heavy gloves to help pre-
vent glass splinters from entering your eyes or cutting your hands.
CAUTION:
When a windshield glass is to be reused, do not use a cutting knife or power cutting tool.
Be careful not to scratch the glass when removing.
Do not set or stand the glass on its edge. Small chips may develop into cracks.
INSTALLATION
The dam rubber should be installed in position.
Use a genuine Nissan Urethane Adhesive Kit (if available) or equivalent and follow the instructions fur-
nished with it.
While the urethane adhesive is curing, open a door window. This will prevent the glass from being forced
out by passenger room air pressure when a door is closed.
The molding must be installed securely so that it is in position and leaves no gap.
Inform the customer that the vehicle should remain stationary until the urethane adhesive has completely
cured (preferably 24 hours). Curing time varies with temperature and humidity.
WAR NING :
Keep heat and open flames away as primers and adhesive are flammable.
The materials contained in the kit are harmful if swallowed, and may irritate skin and eyes. Avoid
contact with the skin and eyes.
Use in an open, well ventilated location. Avoid breathing the vapors. They can be harmful if
inhaled. If affected by vapor inhalation, immediately move to an area with fresh air.
Driving the vehicle before the urethane adhesive has completely cured may affect the perfor-
mance of the windshield in case of an accident.
CAUTION:
Do not use an adhesive which is past its usable term. Shelf life of this product is limited to six
months after the date of manufacture. Carefully adhere to the expiration or manufacture date
printed on the box.
Keep primers and adhesive in a cool, dry place. Ideally, they should be stored in a refrigerator.
Do not leave primers or adhesive cartridge unattended with their caps open or off.
The vehicle should not be driven for at least 24 hours or until the urethane adhesive has com-
pletely cured. Curing time varies depending on temperature and humidity. The curing time will
increase under lower temperature and lower humidity.
Repairing Water Leaks for Windshield
Leaks can be repaired without removing and reinstalling glass.
If water is leaking between the urethane adhesive material and body or glass, determine the extent of leakage.
This can be done by applying water to the windshield area while pushing glass outward.
To stop the leak, apply primer (if necessary) and then urethane adhesive to the leak point.

ENGINE OIL LEVEL
NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop
it and allow 10 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and make sure the engine oil level is within
the range shown in the figure.
3. If it is out of range, adjust it.
NOTE:
When checking the engine oil level, insert oil level gauge with its
tip aligned with oil level gauge guide on cylinder head. (In figure,
air cleaner case and air duct are removed.)
ENGINE OIL APPEARANCE
Check engine oil for white turbidity or heavy contamination.
If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following areas:
Oil pans (lower and upper)
Oil pan drain plug
Oil pressure switch
Oil filter
Oil filter bracket (AWD models)
Oil cooler
Water pump cover
Chain tensioner cover
Intake valve timing control cover and intake valve timing control solenoid valve
Mating surface between cylinder head and rocker cover
Mating surface between front timing chain case and rear timing chain case
Mating surface between rear timing chain case and cylinder head
Mating surface between rear timing chain case and cylinder block
Mating surface between rear timing chain case and oil pan (upper)
Mating surface between cylinder block and cylinder head

ENGINE MAINTENANCE (VK45DE ENGINE)PFP:10001
Checking Drive BeltsNLS0007Q
WAR NING :
Be sure to perform when the engine is stopped.
Remove air duct (inlet) when inspecting drive belt for alternator, water pump and A/C compressor.
Remove front engine undercover with power tool when inspecting power steering oil pump belt.
Make sure that indicator (single line notch) of each auto tensioner is within the allowable working range
(between three line notches).
NOTE:
Check auto tensioner indication when engine is cold.
When new drive belt is installed, the range should be “A”.
The indicator notch is located on the moving side of the tensioner for alternator, water pump and A/C
compressor belt, while it is found on the fixed side for power steering oil pump belt.
Visually check entire belt for wear, damage or cracks.
If the indicator is out of allowable working range or belt is damaged, replace belt.
Te n s i o n A d j u s t m e n tNLS0007R
Belt tensioning is not necessary, as it is automatically adjusted by auto tensioner.
Changing Engine CoolantNLS0007S
WAR NING :
To avoid being scalded, do not change engine coolant when 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 pressure. Then turn radiator cap all the way.
Be careful not to allow engine coolant to contact drive belts.
DRAINING ENGINE COOLANT
1. Remove engine room cover (RH and LH) Refer to EM-173, "ENGINE ROOM COVER" .
2. Remove engine cover with power tool. Refer to EM-179, "
INTAKE MANIFOLD" .
3. Open radiator drain plug at the bottom of radiator, and then remove radiator cap.
