• 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 leak age 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.
Summary of the inspection items:
* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc. : Vehicle front

.
2. Install engine to engine stand as follows;
a. Remove flywheel (M/T models) or drive plate (1) (A/T or CVT models).
• Secure flywheel (M/T models) or drive plate (A/T or CVT mod-
els) using Tool (A), and remove bolts.
CAUTION:
Be careful not to damage or scratch drive plate (A/T or CVT
models) and contact surface for clutch disc of flywheel (M/T
models).
NOTE:
Figure shows drive plate (1) (A/T or CVT models)
b. Lift the engine with a hoist to install it onto widely use engine stand. CAUTION:
• Use the engine stand that has a load capacity [approximately 135 kg (298 lb) or more] large
enough for supporting the engine weight.
• If the load capacity of stand is not adequate, remo ve the following parts beforehand to reduce the poten-
tial risk of overturning stand.
- Exhaust manifold; Refer to EM-144 .
- Rocker cover; Refer to EM-153 .
NOTE:
The figure shows an example of widely used engine stand (A)
that can support mating surface of transaxle with flywheel (M/T
models) or drive plate (A/T or CVT models) removed.
CAUTION:
Before removing the hanging chains, make sure the engine
stand is stable and there is no risk of overturning.
3. Remove oil pan (upper and lower). Refer to EM-147 .
4. Remove cylinder head. Refer to EM-185 .
5. Remove thermostat housing. Refer to CO-45 .
6. Remove knock sensor. CAUTION:
Carefully handle knock sensor avoiding shocks.
7. Remove crankshaft position sensor (POS) cover and crankshaft position sensor (POS).

FRONT SUSPENSION ASSEMBLY
On-Vehicle Inspection and Service INFOID:0000000004305863
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 bet ween 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 Inspection INFOID:0000000004305864
PRELIMINARY INSPECTION WARNING:
Always adjust the alignment with the vehicle on a flat surface.
NOTE:
If alignment is out of specification, inspect and r eplace 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 calib rated 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)
