Removal and InstallationBBS0059F
WARNING:

Situate vehicle on a flat and solid surface.

Place chocks at front and back of rear wheels.

For engines not equipped with engine slingers, attach proper slingers and bolts described in
PARTS CATALOG.
CAUTION:

Always be careful to work safely, avoid forceful or uninstructed operations.

Do not start working until exhaust system and engine 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
unavoidable reasons, support at the rear axle jacking point with 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-37, "Garage Jack and
Safety Stand and 2-Pole Lift" .

Removal
1. Install engine slingers into front left of cylinder head and rear right of cylinder head.

Use alternator bracket mounting bolt holes for the front side.
2. Lift with hoist and secure engine in position.
3. Use manual lift table caddy (commercial service tool) or equiva-
lently rigid tool such as transmission jack. Securely support bot-
tom of front suspension member, and simultaneously adjust
hoist tension.
CAUTION:
Put a piece of wood or something similar as the supporting
surface, secure a completely stable condition.
4. Separate RH engine mounting insulator and RH engine mounting bracket.
5. Pull LH engine mounting through-bolt out.
6. Remove front suspension member mounting nuts and bolts. Refer to FSU-5, "
FRONT SUSPENSION
ASSEMBLY" .
7. Remove engine and transaxle assembly with front suspension member from vehicle downward by care-
fully operating supporting tools.
CAUTION:

During the operation, make sure that no part interferes with vehicle side.

Before and during this lifting, always check if any harnesses are left connected.

During the removal operation, always be careful to prevent vehicle from falling off the lift due to
changes in the center of gravity.

If necessary, support vehicle by setting jack or equivalent tool at the rear.
8. Remove power steering oil pump with piping connected from engine. Refer to PS-29, "
POWER STEER-
ING OIL PUMP" .
9. Remove front engine mounting and rear engine mounting through-bolts to remove front suspension mem-
ber.
10. Remove starter motor. Refer to SC-14, "
STARTING SYSTEM" .
11. Remove each engine mounting insulator and each engine mounting bracket from engine, transaxle and
front suspension member.
12. Separate engine and transaxle. Refer to AT- 2 4 1 , "
TRANSAXLE ASSEMBLY" .
INSTALLATION
Note the following, and install in the reverse order of removal.

Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting
insulator.

When installation directions are specified, install parts according to the direction marks on them referring
to the figure of components. Refer to EM-77, "
Removal and Installation" .

Make sure that each engine mounting insulator is seated properly, and tighten mounting nuts and bolts.Slinger 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.

Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required

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.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.

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.

Valve ClearanceBBS004W2
INSPECTION
In cases of removing/installing or replacing camshaft and valve-
related parts, or of unusual engine conditions due to changes in
valve clearance (found malfunctions during stating, idling or causing
noise), perform inspection as follows:
1. Remove rocker covers (right and left banks). Refer to EM-160, "
ROCKER COVER" .
2. Remove splash guard (RH).
3. Measure the valve clearance as follows:
a. Set No. 1 cylinder at TDC of its compression stroke.

Rotate crankshaft pulley clockwise to align timing mark
(grooved line without color) with timing indicator.

Make sure that intake and exhaust cam noses on No. 1 cylin-
der (engine front side of right bank) are located as shown in
the figure.

If not, rotate crankshaft one revolution (360 degrees) and
align as shown in the figure.
