INSTALLATION
The engine cylinder head gasket is a composition
gasket. The gasket is to be installed DRY. DO NOT
use a gasket sealing compound on the gasket.
If the engine cylinder head is to be replaced and
the original valves used, measure the valve stem diameter.
Only standard size valves can be used with a
service replacement engine cylinder head unless the
replacement head valve stem guide bores are reamed
to accommodate oversize valve stems. Remove all
carbon buildup and reface the valves.

(1) Fabricate two engine cylinder head alignment
dowels from used head bolts (Picture 1). Use the longest
head bolt. Cut the head of the bolt off below the hex
head. Then cut a slot in the top of the dowel to allow
easier removal with a screwdriver.



(2) Install one dowel in bolt hole No.10 and the
other dowel in bolt hole No.8 (Picture 2).



(3) Remove the shop towels from the cylinder
bores. Coat the bores with clean engine oil.

(4) Place the engine cylinder head gasket (with the
numbers facing up) over the dowels.

(5) Place the engine cylinder head over the dowels.

CAUTION: Engine cylinder head bolts should be reused
only once. Replace the head bolts if they were
used before or if they have a paint dab on the top
of the bolt.

(6) Coat the threads of bolt No.7, only, with Loctite
PST sealant or equivalent.

(7) Install all head bolts, except No.8 and No.10.

(8) Remove the dowels.

(9) Install No.8 and No.10 head bolts.

(10) Tighten the engine cylinder head bolts in sequence
according to the following procedure (Fig. 6):
(a) Tighten all bolts in sequence (1 through 10)
to 30 Nm (22 ft. lbs.) torque.
(b) Tighten all bolts in sequence (1 through 10)
to 61 Nm (45 ft. lbs.) torque.
(c) Check all bolts to verify they are set to 61
Nm (45 ft. lbs.) torque.
(d) Tighten bolts (in sequence):
-> Bolts 1 through 6 to 149 Nm (110 ft. lbs.) torque.
-> Bolt 7 to 136 Nm (100 ft. lbs.) torque.
-> Bolts 8 through 10 to 149 Nm (110 ft. lbs.) torque.

CAUTION: During the final tightening sequence,
bolt No.7 will be tightened to a lower torque than
the rest of the bolts. DO NOT overtighten bolt No.7.

(e) Check all bolts in sequence to verify the correct
torque.
(f) If not already done, clean and mark each bolt
with a dab of paint after tightening. Should you
encounter bolts which were painted in an earlier
service operation, replace them.



(11) Install the ignition coil and bracket assembly.

(12) Connect the temperature sending unit wire
connector.

(13) Install the spark plugs and tighten to 37 Nm
(27 ft. lbs.) torque. Connect the ignition wires.

(14) Install the intake and exhaust manifolds (refer
to Group 11, Exhaust System and Intake Manifold
for the proper procedures).

(15) Install the fuel lines and the vacuum advance
hose.

(16) If equipped, attach the power steering pump
and bracket.

(17) Install the push rods, rocker arms, pivots and
bridges in the order they were removed.

(18) Install the engine cylinder head cover.

(19) Attach the air conditioning compressor mounting
bracket to the engine cylinder head and block.
Tighten the bolts to 40 Nm (30 ft. lbs.) torque.

(20) Attach the air conditioning compressor to the
bracket. Tighten the bolts to 27 Nm (20 ft. lbs.)
torque.

CAUTION: The serpentine drive belt must be routed
correctly. Incorrect routing can cause the water
pump to turn in the opposite direction causing the
engine to overheat.

(21) Install the serpentine drive belt and correctly
tension the belt.

(22) Install the air cleaner and ducting.

(23) Install the engine cylinder head cover.

(24) Connect the hoses to the thermostat housing
and fill the cooling system to the specified level.

(25) The automatic transmission throttle linkage
and cable must be adjusted after completing the engine
cylinder head installation.

(26) Install the temperature sending unit and connect
the wire connector.

(27) Connect the fuel pipe and vacuum advance
hose.

(28) Connect negative cable to battery.

(29) Connect the upper radiator hose and heater
hose at the thermostat housing.

(30) Fill the cooling system. Check for leaks.

WARNING: USE EXTREME CAUTION WHEN THE
ENGINE IS OPERATING. DO NOT STAND IN DIRECT
LINE WITH THE FAN. DO NOT PUT HANDS NEAR
THE PULLEYS, BELTS OR FAN. DO NOT WEAR
LOOSE CLOTHING.

(31) Operate the engine with the radiator cap off.
Inspect for leaks and continue operating the engine
until the thermostat opens. Add coolant, if required.
