ENGINE ASSEMBLY
4.
Install engine slinger to front cover front left side (A) and cylinder
head rear right side (B).
5.
Remove starter motor. Refer to
.
6.
Lift with a hoist and separate the engine from the transaxle assembly. Refer to
.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
• Never allow engine oil to get on engine mounting insulator. Be careful not to damage engine mount-
ing insulator.
• Check that each mounting insulator is seated properly, and tighten mounting nuts and bolts.
• When installation directions are specified, install parts according to the direction marks on them
referring to the figure of components. Refer to
AWD : Inspection
INFOID:0000000009753598
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.

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 and the transaxle assembly from the vehicle, and separate the transaxle from the
engine. Refer to
EM-61, "2WD : Removal and Installation"
(2WD models) or
(AWD models).
2.
Install engine to engine stand with the following procedure:
a.
Remove flywheel (M/T models) or drive plate (CVT models).
• Secure flywheel (M/T models) or drive plate (CVT models) (1)
with a stopper plate [SST: KV11105210 (J-44716)] (A), and
remove mounting bolts.
NOTE:
This figure shows CVT models as an example.
b.
Remove pilot converter (1) (CVT models) or pilot bush (M/T
models) using pilot bushing puller [SST: ST16610001 (J-23907)]
(A) or suitable tool.
NOTE:
This figure shows CVT models as an example.
c.
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
- Catalyst converter: Refer to
(AWD models).
- Rocker cover: Refer to

stand is stable and there is no risk of overturning.
3.
Drain engine oil. Refer to
.
CAUTION:
Be sure to clean drain plug and install with new drain plug washer.

INSPECTION AFTER REMOVAL
Timing Chain
Check for cracks (A) and any excessive wear (B) at link plates and
roller links of timing chain. Replace timing chain if necessary.
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.
NOTE:
If hydraulic pressure inside chain tensioner drops after 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 check there is no leakage of fuel, or any oil/fluids including engine oil and
engine coolant.
• Bleed air from lines and hoses of applicable lines, such as in cooling system.
