ENGINE ASSEMBLY
26. Install engine slinger to cylinder head front left side (A) and rear
right side (B) and support the engine position with a hoist.
27. Support engine and transaxle assembly with a hoist and secure the engine in appropriate position.
28. Use a manual lift table caddy (A) or equivalently rigid tool such
as a transmission jack. Securely support bottom of the engine
and the transaxle, and simultaneously adjust hoist tension.
CAUTION:
Put a piece of wood or something similar as the supporting
surface, secure a completely stable condition.
29. Remove torque rod (RH) (1), engine insulator (RH) (2) and
engine bracket (RH) (3).
30. Remove engine through bolt-securing nut (C).
31. Remove the engine and the transaxle assembly from the vehicle downward by carefully operating sup-
porting tools.
CAUTION:
• During the operation, make sure that no part interferes with the vehicle side.
• Before and during this lifting, always check if any harnesses are left connected.
• During the removal operation, always be careful to prevent the vehicle from falling off the lift due
to changes in the center of gravity.
• If necessary, support the vehicle by setting jack or suitable tool at the rear.
• During operation, securely support the engine by placing a piece of wood under the engine oil
pan and transaxle oil pan. Securely support the engine slingers with a hoist.
32. When the engine hoisting is not performed simultaneously, install engine slinger to cylinder head front left
side and rear right side. Refer to EM-72, "
Component".
33. Remove starter motor. Refer to SC-8
.
34. Lift with a hoist and position above engine.
35. Separate the engine and the transaxle. Refer to AT-226
(A/T models), CVT-178 (CVT models) or MT-16
(M/T models).
INSTALLATION
Note the following, and install in the reverse order of removal.

• When installation directions are specified, install parts according to the directions. Refer to EM-72, "Compo-
nent".
• 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 including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-10
.
• 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, 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 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.

• Be sure to use genuine NISSAN exhaust system parts or equivalents which are specially designed
for heat resistance, corrosion resistance and shape.
• Perform the operation with the exhaust system fully cooled down because the system will be hot
just after the engine stops.
• Be careful not to cut your hand on heat insulator edge.
1. Disconnect harness connector of heated oxygen sensor 2.
• Using Tool, remove heated oxygen sensor 2.
CAUTION:
Be careful not to damage heated oxygen sensor 2.
a.2. Disconnect each joint and mounting rubber.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• Always replace exhaust gaskets and seal bearings with new ones when installing.
• Discard any heated oxygen sensor 2 which has been dropped from a height of more than 0.5 m (19.7
in) onto a hard surface such as a concrete floor; use a new one.
• Before installing a new heated oxygen sensor 2, clean exhaust system threads using the heated oxy-
gen sensor thread cleaner and apply anti-seize lubricant (commercial service tool).
• Do not over tighten heated oxygen sensor 2. Doing so may cause damage to the heated oxygen sen-
sor 2, resulting in the “MIL” coming on.
• Remove deposits from the sealing surface of each connection. Connect them securely to avoid
exhaust leakage.
• Temporarily tighten nuts on the exhaust manifold side and bolts on the vehicle side. Check each part
for unusual interference, and then tighten them to the specified torque.
• When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/left
directions.
Exhaust Manifold to Exhaust Front Tube
1. Securely insert seal bearing (2) into exhaust manifold (1) side in
the direction shown.
• Exhaust front tube (5)
CAUTION:
Be careful not to damage seal bearing surface when install-
ing.
2. Install spring (3), tighten nut (4).
• Be careful that the stud bolt nut does not interfere with the
flanged area ( ).
• Make sure the spring (3) sits properly on the flange surface by
aligning it to the locator dimples.
Exhaust Front Tube to Center Muffler
1. Securely insert seal bearing (2) into exhaust front tube (1) side
in the direction shown.
• Center muffler (5)
CAUTION:
Be careful not to damage seal bearing surface when install-
ing.
2. With spring (3), tighten bolt (4).
• Be careful that the stud bolt does not interfere with the flanged
area ( ).
• Make sure the spring (3) sits properly on the flange surface by
aligning it to the locator dimples.
INSPECTION AFTER INSTALLATION
• With the engine running, check exhaust tube joints for exhaust leakage and unusual noise.
• Check to ensure that brackets and mounting rubbers are installed properly and free from undue stress.
Improper installation could result in excessive noise and vibration.Tool number : KV10114400 (J-38365)
