< SERVICE INFORMATION >[VK45DE]
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.
