CAUTION:
Confirm there is no interference with the vehicle.
Make sure that all connection
points have been disconnected.
Keep in mind the center of the vehicle gravity changes. If necessary, use jack(s) to support the
vehicle at rear jacking point(s) to pr event it from falling it off the lift.
Separation Work
1. Install engine slingers into front of cylinder head (right bank) and
rear of cylinder head (left bank).
To protect rocker cover against damage caused by tilting ofengine slinger, insert spacer between cylinder head and
engine rear lower slinger, in direction shown in the figure.
NOTE:
Spacer is a component part of engine rear upper slinger
assembly.
2. Remove power steering oil pump from engine side. Refer to PS-27, "
On-Vehicle Inspection and Service".
3. Remove engine mounting insulators (RH and LH) under side nuts with power tool.
4. Lift with hoist and separate the engine, the transmi ssion assembly, the transfer assembly and the front
final drive assembly from front suspension member.
CAUTION:
Before and during this lifting, always check if any harnesses are left connected.
Avoid damage to and oil/grease smearing or spills onto engine mounting insulator.
5. Remove alternator. Refer to SC-19, "
System Description".
6. Remove starter motor. Refer to SC-8
.
7. Remove front propeller shaft from the front final drive assembly side. Refer to PR-4, "
On-Vehicle Inspec-
tion".
8. Separate the engine from the transmission assembly. Refer to AT-241, "
Removal and Installation (2WD
Models)".
9. Remove the front final drive assembly from oil pan (upper). Refer to FFD-14, "
Removal and Installation
(VQ35DE Models)".

tool.
11. Remove rear engine mounting member and engine m ounting insulator (rear) from the transmission
assembly.
12. Remove dynamic damper from the transfer assembly.
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 EM-117, "
Component (AWD
Models)".

Make sure all engine mounting insulators are seated properly, then
tighten mounting nuts.
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-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, 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 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.
