ENGINE ASSEMBLY
 Avoid damage to and oil/grease smearing or
spills onto engine mounting insulator.
4. Remove alternator. Refer to SC-19, "
System Description".
5. Remove starter motor. Refer to SC-8, "
System Description".
6. Separate engine from transmission assembly. Refer to AT-243, "
Removal and Installation (AWD Models)".
7. Remove front final drive from engine. Refer to FFD-14, "
Removal and Installation (VQ35DE Models)".
8. Remove engine mounting insulators (RH and LH) and brackets (RH and LH) from engine with power tool.
9. Remove engine rear member and engine mounting insulator (rear) from transmission.
INSTALLATION
Note the following, and install in the reverse order of removal.
 Do not allow engine mounting insulator to be damage and careful no engine oil gets on it.
 For a location with a positioning pin, insert it securely into hole of mating part.
 For a part with a specified installation orientation, refer to component figure in "Removal and Installation".
 When installing engine mounting brackets (RH and LH) on cylinder
block, tighten two upper bolts (show n as “A” in the figure) first.
Then tighten two lower bolts (shown as “B” in the figure).
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The followings 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-9, "
Fluids and Lubricants".
 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 applic able 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.

DISASSEMBLY
NOTE:
Explained here is how to disassemble with engine stand supporting transmission surface. When using differ-
ent type of engine stand, note with difference in steps and etc.
1. Remove engine assembly from vehicle, and separa te front suspension member, transmission and front
final drive from engine. Refer to EM-237, "
Component".
2. Remove the parts that may restrict installation of engine to widely use engine stand. NOTE:
The procedure is described assuming that you use wi dely use engine holding the surface, to which trans-
mission is installed.
a. Remove drive plate.  Holding ring gear with ring gear stopper (SST).
 Loosen mounting bolts diagonally order.
CAUTION:
 Do not disassemble drive plate.
 Do not place drive plate with signal plate facing down.
 When handling signal plate, take care not to damage or scratch it.
 Handle signal plate in a manner that prevents it from becoming magnetized.
b. Remove engine rear plate.
3. Lift engine with hoist to install it onto widely use engine stand. CAUTION:
Use engine stand that has a load capacity [approximately 240 kg ( 529 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.
- Intake manifolds (upper and lower): Refer to EM-175, "
Component".
- Exhaust manifold: Refer to EM-179, "
Component".
- Fuel tube and fuel injector assembly: Refer to EM-190, "
Component".

c. Then tighten all connecting rod nuts 60 degrees clockwise.
(Angle tightening)
CAUTION:
Use angle wrench (SST) to ch eck tightening angle. Do not
make judgment by visual inspection.
 After tightening connecting rod nuts, make sure that crank-
shaft rotates smoothly.
 Check the connecting rod side clearance. Refer to EM-256,
"Inspection After Disassembly".
16. Install knock sensor.  Install it with its connector facing the rear of engine.
 Install the sub-harness with its shorter branch line to the rightbank.
CAUTION:
 Do not tighten mounting bolts while holding connector.
 If any impact by dropping is applied to knock sensor, replace it with new one.
NOTE:
 Make sure that there is no foreign material on the cylinder block mating surface and the bac k surface of knock sensor.
 Make sure that knock sensor does not interfere with other parts.
17. Note the following, and assemble in the re verse order of disassembly after this step.
Drive plate When installing drive plate to crankshaft, be sure to correctly
align crankshaft side guide pin and drive plate side guide pin
hole.
- If these are not aligned correctly, engine runs roughly and
“MIL” turns on.
 Install drive plate, reinforcement plate and pilot converter (if not installed in step 4) as shown in the figure.
 Face chamfered or rounded edge side to crankshaft.
 Holding ring gear with ring gear stopper [SST: J-45476].
 Tighten mounting bolts crosswise over several times.
 When install pilot converter, using drift [outer diameter: approx. 35 mm (1.38 in)]. Press-fit as far as it will go.
CAUTION:
Make sure that guide pin is installed at the rear end of
crankshaft.

Checking Exhaust SystemINFOID:0000000001327114
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage or deterioration.
• If anything is found, repair or replace damaged parts.
ComponentINFOID:0000000001327115
CAUTION:
• Be sure to use genuine exhaust system parts or
equivalents which are specially designed for heat
resistance, corrosion resistance, and shape.
 Perform the operation with the exhaust system full y cooled down because the system will be hot
just after engine stops.
 Be careful not to cut your hand on the heat insulator edge.

 Tighten main muffler mounting bracket bolts in numerical order as
shown in the figure.
CAUTION:
 Always replace exhaust tube gasket s with new ones when reassembling.
 If heat insulator is badly deformed, repair or repl ace it. If deposits such as mud pile up on the heat
insulator, remove them.
 When installing heat insulator avoid large gaps or interference between heat insulator and each
exhaust pipe.
 Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gases leakage.
 Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehicle
side. Check each part for unusual interference, an d then tighten them to the specified torque.
 When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/left
directions.
INSPECTION AFTER INSTALLATION
 Make sure clearance between tail tube and bumper is even.
 With engine running, check exhaust tube joints for gas leakage and unusual noises.
 Check to ensure that mounting brackets and mount ing rubbers are installed properly and free from undue
stress. Improper installation could resu lt in excessive noise and vibration.
