ENGINE ASSEMBLY
• 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-11, "
Fluids and Lubricants".
• Use procedure below to check for fuel leaks.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leaks
at connection points.
• Start engine. With engine speed increased, che ck again for fuel leaks at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there are no l eaks of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.

NOTE:
The following procedures explain how to disassemble the engine with the engine stand fastened to the bell
housing. Some steps may be different if using a different type of engine stand.
1. Install engine to engine stand:
a. On (M/T models), remove flywheel.
• Secure flywheel using suitable tool and remove bolts.
CAUTION:
• Do not disassemble flywheel.
• Do not 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.
b. On (CVT models), remove driveplate. • Secure driveplate using suitable tool and remove bolts.
CAUTION:
• Do not disassemble flywheel.
• Do not place flywheel or drive plat e 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.
c. Lift the engine with a hoist to install it onto a widely used engine stand. CAUTION:
• Use the engine stand that has a load capacity approximately 150 kg (331 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 EM-28, "
Exploded View".
- Exhaust manifold. Refer to EM-31, "
Removal and Installation".
- Rocker cover. Refer to EM-48, "
Exploded View".
CAUTION:
Before removing the hanging chains, check the engine stand is stable and there is no risk of over-
turning.
NOTE:
The figure shows an example of widely used engine stand (A)
that can support the mating surface of transaxle with flywheel
removed.
2. Drain engine oil. Refer to LU-8, "
Draining".
CAUTION:
• Be sure to clean drain plug and in stall with new drain plug washer.
• Do not reuse drain plug washer. Tool number : KV11105210 (J-44716)
