TRANSMISSION ASSEMBLY
 Align the positions of tightening bolts for drive plate with those ofthe torque converter, and temporarily tighten the bolts. Then,
tighten the bolts with the specified torque. Refer to "COMPO-
NENTS (FOR VQ35DE)" or "COMPONENTS (FOR VK45DE)".
CAUTION:
 Do not reuse O-ring and copper washers.
 When turning crankshaft, turn it clockwise as viewed from the
front of the engine.
 When tightening the tightening bolts for the torque converter
after fixing the crankshaft pulley bolts, be sure to confirm the
tightening torque of the crankshaft pulley mounting bolts.
Refer to EM-65, "
Removal and Installation" (for VQ35DE) or
EM-200, "
Removal and Installation" (for VK45DE)
 After converter is installed to drive plate, rota te crankshaft several turns and check to be sure that
transmission rotates fr eely without binding.
 Install crankshaft position sensor (POS). Refer to EM-35, "
Component (AWD Models)" (for VQ35DE) or EM-
183, "Component" (for VK45DE).
 After completing installation, check A/T fluid leakage, A/T fluid level, and the positions of A/T. Refer to AT- 11 ,
"Checking A/T Fluid", AT-207, "Checking of A/T Position".

INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates 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 GI-44, "
Recommended Chemical Product and Sealant".
 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. NOTE:
If hydraulic pressure inside chain tensioner drops af ter removal/installation, slack in guide may generate a
pounding noise during and just after the engine start. However, this does not indicate an unusualness. Noise
will stop after hydraulic pressure rises.
 Warm up engine thoroughly to make sure there is no leakage of fuel, or any oil/fluids including 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.

4. Crank the engine, and then make sure that engine oil comes out
from camshaft bracket (No. 1) oil hole. End crank after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
Engine oil may squirt from in take valve timing control sole-
noid valve installation hole during cranking. Use a shop
cloth to prevent the engine components and the vehicle. Do
not allow engine oil to get on rubber components such as
drive belt or engine mount insulators. Immediately wipe off
any splashed engine oil.
 Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not come out from camshaft bracket (No. 1) oil hole. Refer to LU-4, "
Lubrication Circuit".
5. Remove components between intake valve timing control solenoid valve and camshaft sprocket (INT), and then check each oil groove for clogging.
 Clean oil groove if necessary. Refer to LU-4, "
Lubrication Circuit".
6. After inspection, install removed parts.
Inspection for Leaks
The following are procedures for chec king fluids leak, lubricates 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, "
