• Check if the contact area band is continuous all around the circum-
ference.
• If not, grind to adjust valve fitting and check again. If the contacting
surface still has NG conditions even after the re-check, replace
valve seat.
VALVE SEAT REPLACEMENT
When valve seat is removed, replace with oversized [0.5 mm (0.020 in)] valve seat.
1. Bore out old seat until it collapses. Boring shoul d not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this. Refer to EM-223, "
Standard and Limit".
2. Ream cylinder head (1) recess diameter for service valve seat.
• Be sure to ream in circles concentric to the valve guide center.This will enable valve seat to fit correctly.
3. Heat cylinder head to 110° to 130°C (230° to 266° F) by soaking
in heated oil (A).
4. Use dry ice to thoroughly cool valve seats. Press-fit valve seat into cylinder head. WARNING:
• Never touch cold valve seats directly.
• Cylinder head contains heat, wh en working, wear protective equipment to avoid getting burned.
5. Using valve seat cutter set or valve seat grinder, finish valve seat to the specified dimensions. For dimensions, refer to EM-
223, "Standard and Limit".
CAUTION:
When using valve seat cutter, firmly grip the cutter handle
with both hands. Then, press on the contacting surface all
around the circumference to cu t in a single drive. Improper
pressure on the cutter or cutting many different times may
result in staged valve seat.
6. Using compound, grind to adjust valve fitting.
7. Check again for normal contact.

ENGINE ASSEMBLY
• Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting insu-
lator.
• When installation directions are specified, install parts according to the directions. Refer to EM-191, "
Com-
ponent".
• Prior to installing the upper torque rod, apply a light coat of silicone lubricant (A) to the washer facing side of the bushing inner tube as
shown.
NOTE:
• Apply silicone lubricant (A) by dabbing the outward facing tube
surface with a sponge or suitable tool.
• Do not apply excess lubricant.
• 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 incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14
.
• 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 leak-
age at connection points.
- Start engine. With engine speed increased, che ck 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 includ- ing 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.

On-Vehicle Inspection and ServiceINFOID:0000000005397061
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:0000000005397062
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-6, "
Inspection" .
4. Check the wheel bearing axial end play. Refer to FAX-6, "
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-19, "
Wheelarch Height (Unladen*)" .
GENERAL INFORMATION AND RECOMMENDATIONS
1. A Four-Wheel Thrust Alignment should be performed.
• This type of alignment is re commended 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 ca pable 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 a lignment 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 alignm ent machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.
• The alignment specifications programmed into your alignment machine that operate these indicators may not be correct.Axial end play : 0 mm (0 in)
