ENGINE ASSEMBLY

6. Remove front suspension member mounting nuts and bolts. Refer to FSU-5, "FRONT SUSPENSION
ASSEMBLY" .
7. Carefully lower engine, transaxle and front suspension member assembly. When performing work,
observe the following caution.
CAUTION:

Confirm there is no interference with vehicle.

Make sure that all connection points have been disconnected.

Keep in mind the center of vehicle gravity changes. If necessary, use jack(s) to support vehicle
at rear jacking point(s) to prevent it from falling it off the lift.
Separation Work
1. Remove power steering oil pump, power steering piping and power steering bracket from engine and tran-
saxle assembly. Refer to PS-39, "
HYDRAULIC LINE" .
2. Remove starter motor. Refer to SC-14, "
STARTING SYSTEM" .
3. Disconnect harness connector of engine mounting insulators (front and rear).
4. Remove engine mounting (front) and engine mounting (rear) through-bolts.
5. Lift with hoist and separate engine and transaxle assembly from front suspension member.
CAUTION:
Before and during this lifting, always make sure that any harnesses are not connected.
6. Remove each engine mounting insulator and each engine mounting bracket from engine, transaxle and
front suspension member.
7. Separate engine and transaxle. Refer to AT- 2 4 1 , "
TRANSAXLE ASSEMBLY" (A/T), CVT-193, "TRAN-
SAXLE ASSEMBLY" (CVT).
INSTALLATION
Note the following, and install in the reverse order of removal.

Do not allow engine mounting insulator to be damage and careful no engine oil gets on it.

For a path with a specified installation orientation, refer to component figure in EM-223, "Removal and
Installation" .

Make sure all engine mounting insulators are seated properly, then tighten nuts and bolts.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.

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-14, "
RECOMMENDED 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
leakage 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
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.

On-Vehicle Inspection BES0003K
Make sure that the mounting conditions (looseness, back lash) of each component and component status
(wear, damage) are normal.
INSPECTION OF TRANSVERSE LINK BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Measure axial end play by placing an iron pry bar or a similar item between suspension arm and strut
assembly and prying up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.
STRUT INSPECTION
Check for oil leakage, damage, and breakage of installation positions.
Wheel Alignment InspectionBES0003L
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen” conditions mean that fuel, engine coolant, and lubricant are full. A spare tire, a jack, hand tools and
mats are in designated positions.
PRELIMINARY CHECK
1. Check Tires for improper air pressure and wear.
2. Check Road wheels for runout. Refer to WT-3, "
ROAD WHEEL" .
3. Check Wheel bearing axial end play. Refer to FAX-5, "
WHEEL BEARING INSPECTION" .
4. Check Transverse link ball joint axial end play. Refer to FSU-14, "
INSPECTION AFTER REMOVAL" .
5. Check Strut operation.
6. Check Each mounting point of axle and suspension for looseness and deformation.
7. Check Each link, rod, and member for cracks, deformation and other damage.
8. Check Vehicle height (posture).
INSPECTION OF CAMBER, CASTER AND KINGPIN INCLINATION ANGLES.

Camber, caster, kingpin inclination angles cannot be adjusted.

Before inspection, mount wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so vehicle will remain horizontal.
Using a CCK Gauge
Install CCK gauge attachment [SST:KV991040S0] with the following procedure on wheel, then measure wheel
alignment.
1. Remove three wheel nuts, and install the guide bolts to hub
bolts.
2. Screw adapter into the plate until it contacts the plate tightly.
3. Screw center plate into the plate.
4. Insert plate on guide bolt. Put spring in, and then evenly screw
both guide bolt nuts. When fastening guide bolt nuts, do not
completely compress the spring.Axial end play : 0 mm (0 in)
