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-10, "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 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:
*: Power steering fluid, brake fluid, etc.

UNIT DISASSEMBLY AND ASSEMBLY
ENGINE STAND SETTING
Setting
INFOID:0000000009652785
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
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
.
- Remove intake manifold. Refer to
.
- Remove fuel injector and fuel tube assembly. Refer to
.
- Remove ignition coil. Refer to
- Remove rocker cover. Refer to
- Remove exhaust manifold. Refer to
- Other removable brackets.

ENGINE STAND SETTING
The figure shows an example of widely use engine stand (A)
that can hold mating surface of transaxle with drive plate
removed.
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
.
6.
Drain engine coolant by removing water drain plugs (A) and (B)
from cylinder block both sides as shown in the figure.
NOTE:
For Canada, water drain plug (A) in the figure is not water drain
plug but block heater. Refer to
.
