• 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-11, "FOR USA AND CANADA : 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 dr ops 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 leak age 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.

CAUTION:
• After removing timing chain, do not turn the crankshaft and camsh aft separately, or the valves will
strike the pistons.
• When installing camshafts, chain tensioners, oil seal s, or other sliding parts, lubricate contacting
surfaces with new engine oil.
• Apply new engine oil to bolt threads and seat surfaces when inst alling camshaft sprockets, camshaft
brackets, and crankshaft pulley.

4. After confirming the mating marks are aligned, tighten the cam-
shaft sprocket bolts.
• Secure the camshaft using a wrench at the hexagonal portion
to tighten the bolts.
5. Pull the stopper pins out from the secondary timing chain ten- sioners.
6. Install the crankshaft sprocket on the crankshaft. • Make sure the mating marks on the crankshaft sprocket facethe front of the engine.
7. Install the primary timing chain. • Install primary timing chain so the mating mark (punched) (B)
on camshaft sprocket (C) is aligned with the pink link (A) on
the timing chain, while the mating mark (notched) (E) on the
crankshaft sprocket (D) is aligned with the orange one (F) on
the timing chain, as shown.
• When it is difficult to align mating marks of the primary timing chain with each sprocket, gradually turn the camshaft using a
wrench on the hexagonal portion to align it with the mating
marks.
• During alignment, be careful to prevent dislocation of mating
mark alignments of the secondary timing chains.

REAR TIMING CHAIN CASE
• Before removing the upper oil pan, re
move the crankshaft position sensor (POS).
• Be careful not to damage sensor edges.
• Do not spill engine oil or coolant on drive belt.
1. Remove the engine assembly. Refer to EM-220, "Removal and Installation"
.
2. Remove the oil pan lower and upper. Refer to EM-157, "Removal and Installation (Upper Oil Pan)"
.
3. Remove the front timing chain case. Refer to EM-174, "Removal and Installation"
.
4. Remove the primary and secondary timing chains. Refer to EM-182, "Removal and Installation"
.
5. Remove the rear timing chain case. CAUTION:
• Do not remove the plate metal cover for the oil passage.
• After removing the chain case, do not apply any load to
the case that might bend it.
a. Loosen and remove the rear timing chain case bolts in the order as shown.
b. Cut the sealant using Tool (A) and remove the rear timing chain case.
CAUTION:
• Be careful not to damage the mating surface.
• Do not insert a screwdriver or similar tool, this will dam-
age the mating surfaces.
c. In areas where the cutter is difficult to use, use a plastic hammer to lightly tap (1) the cutter where the liquid gasket is applied. Use
a plastic hammer to slide (2) the cutter by tapping on the side.
