Check and confirm the tightening angle by using the angle
wrench [SST: KV10112100] (A) or protractor. Avoid judg-
ment by visual inspection without the tool.
f. Turn all bolts 75 degrees clockwise again (angle tightening).

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-19, "
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:
*: Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.

ENGINE ASSEMBLY
4. Remove engine mounting insulator (RH) (1), engine mounting
bracket (RH) (2) and engine mounting stay (3).
5. Remove engine mounting through bolt-securing nut (A).
6. Carefully lower jack, or raise lift to remove the engine and the transaxle assembly.
CAUTION:
 Make sure that no part interferes with the vehicle side.
 Before and during this lifting, always check if any harnesses are left connected.
 During the removal, always be careful to prevent the vehicle 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. Remove starter motor. Refer to STR-13, "Removal and Installation".
2. Lift with a hoist and separate the engine from the transaxle assembly. Refer to EM-89, "
Exploded View".
INSTALLATION
Installation is in the reverse order of removal.
 Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting insu-
lator.
 Make sure that each mounting insulator is seated properly, and tighten mounting nuts and bolts.
 Tighten engine mounting insulator (RH) bolts in the numerical
order shown.

pan (upper) and cylinder block. Slide seal cutter by tapping on
the side of tool with a hammer.
CAUTION:
 Be careful not to damage the mating surface.
 A more adhesive liquid gasket is applied compared to pre-
vious types when shipped, so it should not be forced off using a screwdriver, etc. outside the
indicated location.
