INSPECTION AFTER INSTALLATION
Inspection for Leaks
• 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-59, "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 leakage 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:
*: Power steering fluid, brake fluid, etc.

NOTE:
Explained here is how to disassemble with engine stand supporting transmission surface. When using differ-
ent type of engine stand, note with difference in steps and etc.
1.
Remove the engine and the transaxle assembly from the vehicle, and separate the transaxle from the
engine. Refer to
2.
Remove clutch cover and clutch disc. Refer to
CL-22, "HRA2DDT : Removal and Installation"
.
3.
Remove flywheel.
• Secure flywheel with a stopper plate [SST: — (Mot.1431)], and remove mounting bolts.
CAUTION:
• Never disassemble flywheel.
• Never place flywheel 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.
4.
Lift the engine with a hoist to install it onto widely use engine stand.
CAUTION:
• Use the engine stand that has a load capacity [approximately 135 kg (298 lb) or more] large
enough for supporting the engine weight.
• If the load capacity of stand is not adequate, remove the following parts beforehand to reduce the poten-
tial risk of overturning stand.
- Intake manifold: Refer to
- Exhaust manifold: Refer to
- Rocker cover: Refer to
NOTE:
The figure shows an example of widely use engine stand that
can support mating surface of transaxle with flywheel removed.
CAUTION:
Before removing the hanging chains, make sure the engine
stand is stable and there is no risk of overturning.
5.
Drain engine oil. Refer to
.
CAUTION:
Be sure to clean drain plug and install with new drain plug washer.
