• 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 

GI-31, "Garage Jack and

Safety Stand and 2-Pole Lift"

.

NOTE:
When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-
ing.

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.

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.
