ENGINE ASSEMBLY
2007 Versa
INSTALLATION
Note the following, and install in the reverse order of removal.

Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting
insulator.

When installation directions are specified, install parts according to the directions. Refer to EM-73, "Com-
ponents" .

Make sure that each mounting insulator is seated properly, and tighten nuts and bolts.

Tighten engine mounting insulator (RH) bolts in the numerical
order shown.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.

Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

Use procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.

Run engine to check for unusual noise and vibration.

Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.

Bleed air from lines and hoses of applicable lines, such as in cooling system.

After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.

Check the axle and suspension parts for excessive play, wear, or damage.

Shake each front wheel to check for excessive play as shown.
FRONT WHEEL BEARING INSPECTION

Move wheel hub and bearing assembly in the axial direction by hand. Make sure the axial end play is
within specification.

Check that the wheel hub bearing operates smoothly.

Replace the wheel hub assembly if the axial end play exceeds specification, or if the wheel bearing does
not turn smoothly. Refer to RAX-4, "

PRECAUTIONS
Revision: June 20062007 Versa
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.
General PrecautionsEAS001ZA

Do not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any flammable
materials. Special care should be taken when handling any flam-
mable or poisonous materials, such as gasoline, refrigerant gas,
etc. When working in a pit or other enclosed area, be sure to
properly ventilate the area before working with hazardous mate-
rials.
Do not smoke while working on the vehicle.

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 w Tr u c k To w i n gEAS00201
CAUTION:

All applicable local laws regarding the towing operation must be obeyed.

It is necessary to use proper towing equipment to avoid possible damage to the vehicle during
towing operation. Towing is in accordance with Towing Procedure Manual at dealer.

Always attach safety chains before towing.

When towing, make sure that the transmission, steering system and power train are in good order.
If any unit is damaged, dollies must be used.
NISSAN recommends that the vehicle be towed with the driving (front) wheels off the ground as illustrated.
TOWING AN AUTOMATIC TRANSAXLE MODEL WITH FOUR WHEELS ON GROUND
CAUTION:
Never tow an automatic transaxle model with four wheels on the ground as this may cause serious
and expensive damage to the transaxle.
Vehicle Recovery (Freeing a Stuck Vehicle)EAS00202

Tow chains or cables must be attached only to the main structural members of the vehicle.

Pulling devices should be routed so they do not touch any part of the suspension, steering, brake or cool-
ing systems.

Always pull the cable straight out from the front or rear of the vehicle. Never pull on the vehicle at an
angle.

Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or recov-
ery.
WAR NIN G:

Do not spin the tires at high speed. This could cause them to explode and result in serious injury.
Parts of the vehicle could also overheat and be damaged.

Install removable recovery hook securely using wheel nut wrench.
