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.
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.

ENGINE ASSEMBLY


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
Outline
At first, remove engine and transaxle assembly with front suspension member from vehicle downward. Sepa-
rate front suspension member, and then separate engine from transaxle.
Preparation
1. Release fuel pressure. Refer to EC-392, "FUEL PRESSURE RELEASE" .
2. Drain engine coolant from radiator. Refer to CO-34, "
Changing Engine Coolant" .
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belts.
3. Remove the following parts:

Engine cover; Refer to EM-133, "INTAKE MANIFOLD COLLECTOR" .

Hood assembly; Refer to BL-13, "HOOD" .

Front road wheels and tires.
