Checking Fuel LineINFOID:0000000001722976
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
General PrecautionINFOID:0000000001722977
WARNING:
When replacing fuel line parts, be sure to observe the following.
 Put a “CAUTION: FLAMMABLE” sign in the work area.
 Be sure to work in a well ventilated area and have a CO
2 fire extinguisher.
 Do not smoke while working on the fuel system. Keep open flames and sparks away from the work
area.
 Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
CAUTION:
 Use gasoline required by the regulations for octane number. Refer to GI-45, "
Precaution for Fuel
(Unleaded Regular Gasoline Recommended)".
 Before removing fuel line parts, perform the following procedures:
- Release fuel pressure from the fuel lines if necessary. Refer to EC-379, "
Inspection" (HR16DE with
Euro-OBD), EC-681, "
Inspection" (HR16DE without Euro-OBD), EC-1035, "Inspection" (MR18DE).
- Disconnect the battery ground cable.
 Always replace O-rings and clamps with new ones.
 Do not kink or twist tubes when they are being installed.
 Perform work on level surface.
 Do not tighten hose clamps excessively to avoid damaging hoses.
 After connecting fuel tube quick connectors, make sure quick connectors are secure.
Ensure that connector and resin tube do not contact any adjacent parts.
 After installing tubes, make sure there is no fuel leakage at connections in the following steps.
- Apply fuel pressure to fuel lines by turning ignition switch ON (without starting the engine). Then
check for fuel leaks at the fuel tube connections.
- Start engine and rev it up and check for fuel leaks at connections.
 Use only a genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used, the
MIL may come on.
 For servicing “Evaporative Emission System” parts, refer to EC-379, "
Inspection" (HR16DE with
Euro-OBD), EC-683, "
Inspection" (HR16DE without Euro-OBD), EC-1037, "Inspection" (MR18DE).

⇐ : Vehicle front
 Disconnect the quick connector using the following procedure.
- Hold the sides of the connector, push in tabs and pull out the
tube.
- If quick connector and tube on fuel pump assembly are stuck,
push and pull several times until they move. Disconnect them
by pulling.
CAUTION:
 The tube can be removed when the tabs are completely
depressed. Do not twist it more than necessary.
 Do not use any tools to remove the quick connector.
 Keep resin tube away from heat. Be especially careful
when welding near the resin tube.
 Prevent acid liquid such as battery electrolyte, from get-
ting on resin tube.
 Do not bend or twist resin tube during installation and removal.
 To keep the connecting portion clean, free of foreign
materials and to avoid damage, cover them completely
with plastic bags or something similar.
 Do not insert plug to prevent damage to O-ring in quick
connector.

On-Vehicle Inspection and ServiceINFOID:0000000001716890
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION OF LOWER BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Place an iron bar or similar tool between transverse link and steering knuckle.
3. Measure axial end play by prying it up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.
STRUT INSPECTION
Check for oil leakage, damage and replace as necessary.
Wheel Alignment InspectionINFOID:0000000001716891
PRELIMINARY INSPECTION
WARNING:
Always adjust the alignment with the vehicle on a flat surface.
NOTE:
If alignment is out of specification, inspect and replace any damaged or worn rear suspension parts before
making any adjustments.
1. Check and adjust the wheel alignment with the vehicle under unladen conditions. “Unladen conditions”
means that the fuel, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in
their designated positions.
2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for run out and damage. Refer to WT-5, "
Inspection" .
4. Check the wheel bearing axial end play. Refer to FA X - 5 , "
On-Vehicle Inspection and Service" .
5. Check the shock absorbers for leaks or damage.
6. Check each mounting point of the suspension components for any excessive looseness or damage.
7. Check each link, arm, and the suspension member for any damage.
8. Check the vehicle height. Refer to FSU-18, "
Wheelarch Height (Unladen*)" .
GENERAL INFORMATION AND RECOMMENDATIONS
1. A Four-Wheel Thrust Alignment should be performed.
 This type of alignment is recommended for any NISSAN vehicle.
 The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel
is centered.
 The alignment machine itself should be capable of accepting any NISSAN vehicle.
 The alignment machine should be checked to ensure that it is level.
2. Make sure the alignment machine is properly calibrated.
 Your alignment machine should be regularly calibrated in order to give correct information.
 Check with the manufacturer of your specific alignment machine for their recommended Service/Cali-
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to FSU-17, "Wheel
Alignment (Unladen*)" .
1. When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators. Axial end play : 0 mm (0 in)
