Installation

note

●

Thoroughly clean all parts to be assembled.

●

Always use a new cylinder head and manifold gasket.

●

Always use a new cylinder head bolt.

●

The cylinder head gasket is a metal gasket. Take care not to bend it.

●

Rotate the crankshaft, set the No.1 piston at top dead center (TDC).

Install the cylinder head assembly.

(1)

Before installing, remove the hardened sealant from the cylinder block and cylinder head surface.

(2)

Before installing the cylinder head gasket, apply sealant on the upper surface of the cylinder block and reassemble the gasket within five minutes.

note

Refer to the illustration for applying sealant.

Width : 2.0 ~ 3.0 mm (0.0787 ~ 0.1181 in.)

Position : 1.0 ~ 1.5 mm (0.0394 ~ 0.0591 in.)

Specification : THREE BOND 1217H or LOCTITE 5900H

(3)

After installing the cylinder head gasket on the cylinder block, apply sealant on the upper surface of the cylinder head gasket and reassemble in five minutes.

Place the cylinder head carefully not to damage the gasket.

Install the cylinder head bolts with washers.

(1)

Tighten the 10 cylinder head bolts, in several passes, in the sequence shown.

Tightening torque :

[29.4 N.m (3.0 kgf.m, 21.7 lb-ft)] + [90°] + [90°]

caution

Always use new cylinder head bolts.

Install the spark plug.

(Refer to Engine Electrical System - "Spark Plug")

Install the intake oil control valve (OCV).

(Refer to Engine Control/Fuel System - "CVVT Oil Control Valve (OCV)")

Install the water pipe.

(Refer to Cooling System - "Water Temperature Control Assembly")

Install the weter control assembly and bypass hose.

(Refer to Cooling System - "Water Control Assembly")

Install the continuous variable valve timing (CVVT).

(Refer to Cylinder Head Assembly - "CVVT & Camshaft")

Install the intake camshaft (A) and exhaust camshaft (B).

10.

Install the camshaft bearing caps with the order below.

Tightening torque

M6 bolts :

11.8 ~ 13.7 N.m (1.2 ~ 1.4 kgf.m, 8.7 ~ 10.1 lb-ft)

M8 bolts :

18.6 ~ 22.6 N.m (1.9 ~ 2.3 kgf.m, 13.7 ~ 16.6 lb-ft)

11.

Install the timing chain.

(Refer to Timing System - "Timing Chain")

12.

Install the exhaust oil control valve (OCV) adapter (A).

Tightening torque :

9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

13.

Install the other parts in the reverse order of removal.

note

Perform the following :

●

Refill engine with engine oil.

●

Refill a radiator and a reservoir tank with engine coolant.

●

Inspect for fuel leakage.

After assemble the fuel line, turn on the ignition switch (do not operate the starter) so that the fuel pump runs for approximately two seconds and fuel line pressurizes.

Repeat this operation two or three times, then check for fuel leakage at any point in the fuel line.

●

Bleed air from the cooling system.

Start engine and let it run until it warms up. (until the radiator fan operates 3 or 4 times.)

Turn Off the engine. Check the level in the radiator, add coolant if needed. This will allow trapped air to be removed from the cooling system.

Put radiator cap on tightly, then run the engine again and check for leaks.

●

Clean battery posts and cable terminals and assemble.
