(2) Insert Mopar GEN II Silicone Rubber Adhe-
sive Sealant, or equivalent, into the four corner joints
an excessive amount of sealant is not required to
ensure a leak proof seal. However, an excessive
amount of sealant may reduce the effectiveness of
the flange gasket. The sealant should be approxi-
mately 5 mm (0.2 in.) in diameter. (Fig. 70).
(3) Position the cross-over gaskets and press firmly
onto the block (Fig. 70). BE SURE THE BLOCK IS
OIL FREE..
(4) The lower intake manifold MUST be installed
within 3 minutes of sealant application. Carefully
lower intake manifold into position on the cylinder
block and heads. After intake manifold is in place,
inspect to make sure seals and gaskets are in place.
Finger start all the lower intake bolts.
(5) Tighten the lower intake manifold bolts in
sequence to 54 N·m (40 ft. lbs.) torque (Fig. 69).
Recheck all bolts are tightened to 54 N·m (40 ft. lbs.)
torque.
(6) Using a new gasket, position the upper intake
manifold onto the lower intake manifold.
(7) Finger start all bolts, alternate one side to the
other.
(8) Tighten upper
sequence to 22 N·m (16 ft. lbs.) torque (Fig. 68).
(9) Using a new gasket, install the throttle body
onto the upper intake manifold. Tighten the bolts to
23 N·m (200 in. lbs.) torque.
(10) Install closed crankcase ventilation and evap-
oration control systems.
(11) Connect the heater hoses and bypass hose.
(12) Connect the vacuum lines.
(13) Install the coil assemblies and the ignition
wires.
(14) Connect the accelerator linkage and if so
equipped, the speed control and transmission kick-
down cables.

(15) Install the fuel lines (Refer to 14 - FUEL SYS-
TEM/FUEL DELIVERY/QUICK
TING - STANDARD PROCEDURE).
(16) Using a new gasket, install the air cleaner
housing. Tighten the nuts to 11 N·m (96 in. lbs.)
torque. Install the air cleaner filter and cover.
(17) Install the A/C compressor (Refer to 24 -
HEATING & AIR CONDITIONING/PLUMBING/A/C
COMPRESSOR - INSTALLATION). Position the com-
pressor brace and install the bolts. Tighten the brace
bolts to 41 N·m (30 ft. lbs.) torque.
(18) Install the generator (Refer to 8 - ELECTRI-
CAL/CHARGING/GENERATOR - INSTALLATION).
Position the generator brace and install the bolts.
Tighten the brace bolts to 41 N·m (30 ft. lbs.) torque.
(19) Install the accessory drive belt (Refer to 7 -
COOLING/ACCESSORY DRIVE/DRIVE BELTS -
INSTALLATION).
(20) Fill cooling system (Refer to 7 - COOLING -
STANDARD PROCEDURE).
(21) Connect the negative cable to the battery.
(22) Start engine check for leaks.
EXHAUST MANIFOLD
DESCRIPTION
Engine exhaust manifolds (Fig. 72) are made of
high molybdenum ductile cast iron. A special ribbed
design helps control permanent dimensional changes
during heat cycles.

OPERATION
The exhaust manifolds collect the engine exhaust
exiting the combustion chambers, then channels the
exhaust gases to the exhaust pipes attached to the
manifolds.
