Revision: June 20062007 Versa
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.
Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.
WA RN ING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
Precautions for Three Way CatalystEAS001ZB
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
When checking for ignition spark or measuring engine compression, make tests quickly and only when
necessary.

WINDSHIELD GLASS
Revision: June 20062007 Versa
After removing windshield upper molding, 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.
WAR NIN G:
When cutting the glass from the vehicle, always wear safety glasses and heavy gloves to help prevent
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
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 NIN G:
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 the adhesive 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 humidities. The curing time will
increase under lower temperatures and lower humidities.
Repairing Water Leaks
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.

REAR WINDOW GLASS AND MOLDING
Revision: June 20062007 Versa
Remove glass using piano wire or power cutting tool and an
inflatable pump bag.
If the rear window glass is to be reused, mark the body and the
glass with mating marks.
WAR NIN G:
When cutting the glass from the vehicle, always wear safety
glasses and heavy gloves to help prevent glass splinters from
entering your eyes or cutting your hands.
CAUTION:
When a windshield glass is to be reused, do not use a cut-
ting 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
Installation is in the reverse order of removal.
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 compartment air pressure when a door is closed.
The molding must be installed securely so that it is in position and leaves no gap.
Check gap along bottom to confirm that glass does not contact sheet metal.
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 NIN G:
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 temperatures and lower humidities.
Repairing Water leaks for Rear Window Glass
Leaks can be repaired without removing or reinstalling glass.
If water is leaking between urethane adhesive material and body or glass, determine the extent of leakage.
This can be done by applying water to the rear window area while pushing glass outward.
