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
.
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
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"
• 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.
