15. Check the connecting rod cap bolts before reusing, then install

in their original position in the connecting rod. The bolts should

screw in smoothly by hand.

• Measure the outer diameter of the connecting rod cap bolt as

shown.

16. Tighten the connecting rod nuts in two stages using Tool:

CAUTION:

Always use either an angle wrench or protractor. Avoid

tightening based on visual check alone.

• Apply engine oil to the threads and seats of the connecting rod

bolts and nuts.

• After tightening the nuts, make sure that the crankshaft rotates

smoothly.

• Check the connecting rod side clearance. If beyond the limit, replace the connecting rod and/or crank-

shaft.

17. Install the baffle plate to the main bearing beam.
18. Install the knock sensor.

• Make sure that there is no foreign material on the cylinder

block mating surface and the back surface of the knock sen-

sor.

• Install the knock sensor with the connector facing the rear of

the engine.

• Do not tighten the bolts while holding the connector.

• Make sure that the knock sensor does not interfere with other

parts.

CAUTION:

If any impact by dropping occurs to the knock sensor,

replace it with new one.

19. Install the pilot converter with it’s chamfer facing crankshaft as

shown.

20. Install the drive plate. Refer to

EM-127, "Dowel Pin Alignment"

21. Install the cylinder head. Refer to

EM-90, "Removal and Installation"

22. Install the timing chain. Refer to

EM-64, "Removal and Installation"

23. Install the oil pan. Refer to

EM-37, "Removal and Installation (Upper Oil Pan)"

24. Remove the engine from the stand and install the engine assembly into the vehicle. Refer to

EM-103,

"Removal and Installation"

25. Assembly of the remaining parts is in the reverse order of disassembly.

CAUTION:

Do not fill the engine with oil for at least 30 minutes after the components are installed to allow the

sealant to cure.

INSPECTION AFTER INSTALLATION

• 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-15, "FOR USA AND CANADA : Fluids and Lubricants"

(United

States and Canada) or

MA-16, "FOR MEXICO : Fluids and Lubricants"

(Mexico).

• 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.

NOTE:

If hydraulic pressure inside timing chain tensioner drops after removal and 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 gas, or any oils/fluids including

engine oil and engine coolant.

• Bleed air from passages in lines and hoses, such as in cooling system.

• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-

ified level, if necessary.

• Summary of the inspection items:

*Power steering fluid, brake fluid, etc.
