• Always be careful to work safely, avoid forceful or uninstructed operations.
• Never start working until exhaust system and coolant are cool enough.
• If items or work required are not covered by the engine section, refer to the applicable sections.
• Always use the support point specified for lifting.
• Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-
able reasons, support at the rear axle jacking point with a transmission jack or similar tool before
starting work, in preparation for the backward shift of center of gravity.
• For supporting points for lifting and jacking point at rear axle, refer to
NOTE:
When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-
ing.

10. Remove stabilizer connecting rod. Refer to
.
11. Remove front suspension member. Refer to
12. Preparation for the separation work of transaxle is as follows:
• Remove transaxle joint bolts which pierce at oil pan (upper) lower rear side. Refer to
.
Removal
1.
Use a instruction lift table caddy (commercial service tool) or equiv-
alently rigid tool such as a transmission jack. Securely support
bottom of the engine and the transaxle assembly.
CAUTION:
Put a piece of wood or an equivalent as the supporting sur-
face, secure a completely stable condition.
2.

3.
Remove engine mounting insulator (LH) mounting nut
to the
transaxle.
4.
Carefully lower jack, or raise lift to remove the engine and the
transaxle assembly. When performing work, observe the follow-
ing caution.
CAUTION:
• Check that no part interferes with the vehicle side.
• Before and during this lifting, always check if any har-
nesses are left connected.
• During the removal, always be careful to prevent the vehi-
cle from falling off the lift due to changes in the center of
gravity.
• If necessary, support the vehicle by setting jack or suitable tool at the rear.
Separation
1.
Install engine slinger to front cover front left side
and cylinder
head rear right side
.
2.
Remove starter motor. Refer to
STR-26, "MR20DD : Exploded View"
3.
Lift with a hoist and separate the engine from the transaxle assembly. Refer to
(CVT models).
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.

Inspection
INFOID:0000000010783708
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-23, "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.
