PRECAUTIONS
 To prevent damage to rubber hose, do not pry off rubber hose withtapered tool or screwdriver.
 To reinstall the rubber hose securely, make sure that hose insertion length and orientation is correct. (If tube is equipped with hose
stopper, insert rubber hose into tube until it butts up against hose
stopper.)
HOSE CLAMPING
 If old rubber hose is re-used, install hose clamp in its original posi-tion (at the indentation where the old clamp was). If there is a trace
of tube bulging left on the old rubber hose, align rubber hose at
that position.
 Discard old clamps; replace with new ones.
 After installing plate clamps, apply force to them in the direction of the arrow, tightening rubber hose equally all around.
Precaution for Engine OilsINFOID:0000000001325660
Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact
with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.
HEALTH PROTECTION PRECAUTIONS
 Avoid prolonged and repeated contact with oils, particularly used engine oils.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT
 Clean as required to assure good contact.
 Reinstall bolt or screw securely.
 Inspect for “add-on” accessories which may be interfering with the ground circuit.
 If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of thewires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one eye-
let make sure no ground wires have excess wire insulation.
For detailed ground distribution information, re fer to “Ground Distribution” in PG section.
Voltage Drop Tests
Voltage drop tests are often used to find components or circuits which have excessive resistance. A voltage
drop in a circuit is caused by a resistance when the circuit is in operation.
Check the wire in the illustration. When measuring resist ance with DMM, contact by a single strand of wire will
give reading of 0 ohms. This would indicate a good circui t. When the circuit operates, this single strand of wire
is not able to carry the current. The single strand will have a high resistance to the current. This will be picked
up as a slight voltage drop.
Unwanted resistance can be caused by many situations as follows:
 Undersized wiring (single strand example)
 Corrosion on switch contacts
 Loose wire connections or splices.
If repairs are needed always use wire that is of the same or larger gauge.
MEASURING VOLTAGE DROP — ACCUMULATED METHOD
 Connect the DMM across the connector or part of the ci rcuit you want to check. The positive lead of the
DMM should be closer to power and the negative lead closer to ground.
 Operate the circuit.
 The DMM will indicate how many volts are being used to “push” current through that part of the circuit.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
If the noise can be duplicated easily during the test drive, to helpidentify the source of the noise, try to dupli-
cate the noise with the vehiclestopped by doing one or all of the following:
1) Close a door.
2) Tap or push/pull around the area where the noise appears tobe coming from.
3) Rev the engine.
4) Use a floor jack to recreate vehicle “twist”.
5) At idle, apply engine load (electrical load, half-cl utch on M/T models, drive position on A/T models).
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.
 Drive the vehicle and attempt to duplicate the conditi ons thecustomer states exist when the noise occurs.
 If it is difficult to duplicate the noise, drive the v ehicle slowlyon an undulating or rough road to stress the vehi-
cle body.
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technica lService Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, fo llow the procedure to repair thenoise.
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
1. Narrow down the noise to a general area. To help pi npoint the source of the noise, use a listening tool
(Chassis Ear: J39570, Engine Ear and mechanics stethoscope).
2. Narrow down the noise to a more specific area and identify the causeof the noise by:
 removing the components in the area that you suspect the noiseis coming from. Do not use too much force when removing clips and fasteners, otherwiseclips and fastener can be broken or
lost during the repair, resulting in thecreation of new noise.
 tapping or pushing/pulling the component t hat you suspect is causingthe noise.
Do not tap or push/pull the component with excessive force, otherwisethe noise will be eliminated only tem-
porarily.
 feeling for a vibration with your hand by touching t he component(s)that you suspect is (are) causing the
noise.
 placing a piece of paper between components that you suspect arecausing the noise.
 looking for loose components and contact marks. Refer to GW-7, "
Generic Squeak and Rattle Troubleshooting".
REPAIR THE CAUSE
 If the cause is a loose component, tighten the component securely.
 If the cause is insufficient clearance between components:
- separate components by repositioning or l oosening and retighteningthe component, if possible.
- insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane
tape. A Nissan Squeak and Rattle Kit (J43980) is av ailable through your authorized Nissan Parts Depart-
ment.
CAUTION:
Do not use excessive force as many components are constructed of plasticand may be damaged.
NOTE:
Always check with the Parts Departm ent for the latest parts information.
The following materials are contained in the Nissan Squeak and Rattle Kit (J43980). Each item can be ordered

SQUEAK AND RATTLE TROUBLE DIAGNOSES
Most of these incidents can be repaired by adjusting, securing or insulatingthe item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area c an often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knockingnoise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicatingthe conditions can isolate most of these
incidents. Repairs usually consistof insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the pos ition the seatis in and the load placed on the seat when
the noise is present. These conditionsshould be duplic ated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspectedcomponents while duplicating the condi-
tions under which the noise occurs.Most of these incidents can be repaired by repositioning the component
orapplying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or onthe engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the \
vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.
