AWD : Inspection

INFOID:0000000003372983

INSPECTION AFTER INSTALLATION

Inspection for Leakage

The following are procedures for checking fluids leakage, lubricates leakage, and exhaust gases leakage.

• 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-15, "FOR NORTH AMERICA : Fluids and Lubricants"

 (for

North America) or 

MA-16, "FOR MEXICO : Fluids and Lubricants"

 (for Mexico).

• 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 check there is no leakage of fuel, exhaust gases, or any oil/fluids including

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.

DISASSEMBLY AND ASSEMBLY

ENGINE STAND SETTING

Setting

INFOID:0000000003304145

NOTE:
Explained here is how to disassemble with engine stand supporting transaxle surface. When using different
type of engine stand, note with difference in steps and etc.
1.

Remove the engine assembly from the vehicle. Refer to 

EM-68, "2WD : Exploded View"

 (2WD models) or

EM-77, "AWD : Exploded View"

 (AWD models).

2.

Remove the parts that may restrict installation of engine to widely use engine stand.
NOTE:
The procedure is described assuming that you use a widely use engine stand holding the surface, to
which transaxle is installed.
• Remove drive plate. Fix crankshaft pulley with the pulley holder (commercial service tool), and remove

mounting bolts.

• Loosen mounting bolts in diagonal order.
• Check for deformation or damage drive plate.

CAUTION:

• Never disassemble drive plate.
• Never 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.

3.

Remove pilot converter using the pilot bushing puller (SST) if
necessary.

4.

Lift the engine with hoist to install it onto the widely use engine stand.

CAUTION:

Use an engine stand that has a load capacity [220 kg (485 lb) or more] large enough for supporting
the engine weight. 
• If the load capacity of the stand is not adequate, remove the following parts beforehand to reduce the

potential risk of overturning the stand.

- Remove intake manifold collector. Refer to 

EM-29, "Exploded View"

- Remove intake manifold. Refer to 

EM-32, "Exploded View"

.

- Remove fuel injector and fuel tube assembly. Refer to 

EM-45, "Exploded View"

.

- Remove ignition coil. Refer to 

EM-50, "Exploded View"

.

- Remove rocker cover. Refer to 

EM-50, "Exploded View"

.

- Remove exhaust manifold. Refer to 

EM-34, "Exploded View"

.

- Other removable brackets.

CAUTION:

Before removing the hanging chains, check the engine
stand is stable and there is no risk of overturning.

5.

Drain engine oil. Refer to 

LU-8, "Draining"

.

6.

Drain engine coolant by removing water drain plugs (A) and (B)
from cylinder block both sides as shown in the figure.
