INSTALLATION
(1) If removed, position new plenum gasket and
install plenum pan (Fig. 66).
(2) Tighten plenum pan mounting bolts as follows:
• Step 1. Tighten bolts to 5.4 N·m (48 in. lbs.)
• Step 2. Tighten bolts to 9.5 N·m (84 in. lbs.)
• Step 3. Check all bolts are at 9.5 N·m (84 in.
lbs.)

(3) Install the flange gaskets. Ensure that the ver-
tical port alignment tab is resting on the deck face of
the block. Also the horizontal alignment tabs must be
in position with the mating cylinder head gasket tabs
(Fig. 68). The words MANIFOLD SIDE should be vis-
ible on the center of each flange gasket.
(4) Apply Mopar GEN II Silicone Rubber Adhe-
sive Sealant, or equivalent, to 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.
(5) Install the front and rear cross-over gaskets
(Fig. 67).
(6) Using a new gasket, install the throttle body
onto the intake manifold. Tighten the bolts to 23 N·m
(200 in. lbs.) torque.
(7) Carefully lower intake manifold into position
on the cylinder block and cylinder heads. After intake
manifold is in place, inspect to make sure seals are
in place.
