ing chain again after instal ling the timing chain, keep
matching marks aligned by holding them with a hand.
• To avoid skipped teeth, never rotate crankshaft and cam-
shaft until front cover is installed.
15. Install timing chain tension guide (2) and timing chain slack guide (1).
16. Install chain tensioner (1). • Fix the plunger at the most compressed position using a stop-per pin (A), and then install it.
• Securely pull out the stopper pin after installing the chain ten-
sioner.

• If items or work required are not covered by the
engine section, follow the procedures in the applica-
ble sections.
• Always use the support poin t specified for lifting.
• Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-
able reasons, support at the rear axle jacking point with a transmission jack or similar tool before
starting work, in prepar ation for the backward shif t of center of gravity.
• For supporting points fo r lifting and jacking point at rear axle, refer to GI-38, " Garage Jack and
Safety Stand and 2-Pole Lift " .

INSPECTION AFTER INSTALLATION
Inspection for Leaks • Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, " 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 leak-
age 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 leak age of fuel, exhaust gases, or any oil/fluids includ-
ing 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.

ent type of engine stand, note with difference in steps and etc.
1. Remove the engine and the transaxle assembly from the vehicle, and separate the transaxle from the
engine. Refer to EM-88, " Exploded View " .
2. Remove clutch cover and clutch disc (if equipped). Refer to CL-15, " Removal and Installation " .
3. Remove flywheel or driveplate. • Secure flywheel or driveplate with Tool, and remove bolts.

• When handling signal plate, take car e not to damage or scratch it.
• Handle signal plate in a manner that prevents it from becoming magnetized.
4. Lift the engine with a hoist to install it onto widely use engine stand. CAUTION:
• Use the engine stand that has a load capacity [approximately 135 kg (298 lb) or more] large
enough for supporting the engine weight.
• If the load capacity of stand is not adequate, remove the following parts beforehand to reduce the poten-
tial risk of overturning stand.
- Intake manifold: Refer to EM-28, " Exploded View " .
- Exhaust manifold: Refer to EM-31, " Exploded View " .
- Rocker cover: Refer to EM-46, " Exploded View " .
NOTE:
The figure shows an example of widely use engine stand that
can support mating surface of transaxle with flywheel or drive-
plate removed.
CAUTION:
Before removing the hanging chains, make sure the engine
stand is stable and there is no risk of overturning.
5. Drain engine oil. Refer to LU-8, " Draining " .
6. Drain engine coolant by removing water drain plug (1) from RH side of the engine. Tool number : KV11105210 (J-44716)

Confirm the tightening angle by using Tool (A) or protractor.
Avoid judgment by visual inspection without the tool.
• After tightening connecting rod bolts, make sure that crankshaft rotates smoothly.
• Check the connecting rod side clearance. Refer to EM-103, " Inspection " .
15. Install oil pan (upper). Refer to EM-42, " Removal and Installation " .
