When installing engine mounting brackets (RH and LH) on cylin-
der block, tighten two upper bolts (shown as “A” in the figure)
first. Then tighten two lower bolts (shown as “B” in the figure).

Make sure all engine mounting insulators are seated properly, then tighten mounting nuts.

Tighten rear engine mounting member bolts in numerical order
as shown in the figure.

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-11, "
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.

DISASSEMBLY
1. Remove engine assembly from vehicle, and separate front suspension member and transmission from
engine. Refer to EM-101, "
ENGINE ASSEMBLY" .
2. Remove engine mounting brackets (RH and LH). Refer to EM-101, "
ENGINE ASSEMBLY" .
3. Remove the parts that may restrict installation of engine to widely use engine stand.
NOTE:
The procedure is described assuming that you use a widely use engine stand holding the surface, to
which transmission is installed.

Remove clutch cover and clutch disk (M/T models). Refer to CL-16, "CLUTCH DISC, CLUTCH
COVER" .

Remove flywheel (M/T models) or drive plate (A/T models). Fix crankshaft with a ring gear stopper
[SST: KV10118600 (J-48641)], and remove mounting bolts.

Loosen mounting bolts in diagonal order.

Check for deformation or damage (A).
CAUTION:

Do not disassemble drive plate.

Never place drive plate with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.
4. Remove pilot bushing (M/T models) or pilot converter (A/T mod-
els) using pilot bushing puller [SST: ST16610001 (J-23907)] (A)
or suitable tool as necessary.
5. Lift the engine with hoist to install it onto the widely use engine stand.

A widely use engine stand can be used.
CAUTION:
Use engine stand that has a load capacity [approximately
220 kg (485 lb) or more] large enough for supporting the
engine weight.
NOTE:
This example is engine stand for holding at transmission
mounting side with flywheel (M/T models) or drive plate (A/T
models) removed.
6. Drain engine oil. Refer to LU-7, "
Changing Engine Oil" .

7. Drain engine coolant by removing water drain plugs (1, 4) from
cylinder block both sides as shown in the figure.
8. Remove oil pan (upper, lower). Refer to EM-26, "
OIL PAN AND OIL STRAINER" .
9. Remove front timing chain case, timing chain and rear timing chain case. Refer to EM-53, "
TIMING
CHAIN" .
10. Remove cylinder head. Refer to EM-89, "
CYLINDER HEAD" .
11. Remove knock sensor.
CAUTION:
Carefully handle sensor avoiding shocks.
12. Remove rear oil seal.
13. Remove baffle plate from lower cylinder block.
14. Remove piston and connecting rod assembly as follows:

Before removing piston and connecting rod assembly, check the connecting rod side clearance. Refer
to EM-125, "
CONNECTING ROD SIDE CLEARANCE" .
a. Position crankshaft pin corresponding to connecting rod to be removed onto the bottom dead center.
b. Remove connecting rod bearing cap.
c. Using hammer handle or similar tool, push piston and connect-
ing rod assembly out to the cylinder head side.
CAUTION:
Be careful not to damage the cylinder wall and crankshaft
pin, resulting from an interference of the connecting rod big
end.
15. Remove connecting rod bearings from connecting rod and connecting rod bearing cap.
CAUTION:
Identify installation position, and store them without mixing them up.
16. Remove piston rings form piston.

Before removing piston rings, check the piston ring side clearance. Refer to EM-126, "PISTON RING
SIDE CLEARANCE" .

CAUTION:

When removing piston rings, be careful not to damage
piston.

Be careful not to damage piston rings by expanding them
excessively.
17. Remove piston from connecting rod as follows:
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
