INSPECTION AFTER REMOVAL
Cylinder Head Bolts Outer Diameter

Cylinder head bolts are tightened by plastic zone tightening
method. Whenever the size difference between “d1” and “d2”
exceeds the limit, replace them with new one.

If reduction of outer diameter appears in a position other than
“d2”, use it as “d2” point.

Cylinder Head Distortion
NOTE:
When performing this inspection, cylinder block distortion should be also checking. Refer to EM-248, "
CYLIN-
DER BLOCK DISTORTION" .
1. Wipe off oil and remove scale, gasket, sealant and carbon deposits from surface of cylinder head with
scraper.
CAUTION:
Use utmost care not to allow gasket debris to enter passages for engine oil or engine coolant.
2. At each of several locations on bottom surface of cylinder head,
measure the distortion in six directions.

If it exceeds the limit, replace cylinder head.
INSTALLATION
1. Install new cylinder head gaskets.
2. Turn crankshaft until No. 1 piston is set at TDC.

Crankshaft key should line up with the right bank cylinder cen-
ter line as shown in the figure.
3. Install cylinder head follow the steps below to tighten cylinder
head bolts in numerical order as shown in the figure.
a. Apply new engine oil to threads and seat surfaces of cylinder
head bolts.
b. Tighten all cylinder head bolts.
c. Completely loosen all cylinder head bolts.
CAUTION:
In step “c”, loosen bolts in the reverse order of that indi-
cated in the figure.
d. Tighten all cylinder head bolts.Limit : 0.1 mm (0.004 in)

e. Turn all cylinder head bolts 90 degrees clockwise. (Angle tight-
ening)
CAUTION:
Check the tightening angle by using angle wrench (SST).
Avoid judgment by visual inspection without tool.

Check tightening angle indicated on angle wrench (SST) indi-
cator plate.
f. Turn all cylinder head bolts 90 degrees clockwise again. (Angle
tightening)
4. After installing cylinder head, measure distance between front
end faces of cylinder block and cylinder head (left and right
banks).

If the measured value is out of the standard, re-install cylinder
head.
5. Install in the reverse order of removal after this step.

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.

a. Using snap ring pliers, remove snap ring.
b. Heat piston to 60 to 70°C (140 to 158°F) with industrial use drier
or equivalent.
c. Push out piston pin with stick of outer diameter approximately 20
mm (0.79 in).
16. Remove main bearing cap bolts.
NOTE:
Use TORX socket (size E14).

Before loosening main bearing cap bolts, measure crankshaft end play. Refer to EM-245, "CRANK-
SHAFT END PLAY" .
