REMOVAL AND INSTALLATION (Continued)
(13) Disconnect the heater hoses and bypass hose.
(14) Remove the closed crankcase ventilation and
evaporation control systems.
(15) Remove intake manifold bolts.
(16) Lift the intake manifold and throttle body out
of the engine compartment as an assembly.
(17) Remove and discard the flange side gaskets
and the front and rear cross-over gaskets.
(18) Remove the throttle body bolts and lift the
throttle body off the intake manifold (Fig. 35). Dis-
card the throttle body gasket.

INSTALLATION
(1) If the plenum pan was removed, position pan
gasket and pan.
(2) Install plenum pan retaining bolts. (Fig. 36).
(3) Tighten plenum pan mounting bolts as follows:
• Step 1. Tighten bolts to 5.4 N·m (24 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.)
(4) Using a new gasket, install the throttle body
onto the intake manifold. Tighten the bolts to 23 N·m
(200 in. lbs.) torque.
(5) Apply a bead of Mopar Silicone Rubber Adhe-
sive Sealant, or equivalent, to the four corner joints.
The sealant bead height should be slightly higher
than the cross-over gaskets, approximately 5 mm (0.2
in). An excessive amount of sealant is not required to
ensure a leak proof seal, and an excessive amount of
sealant may reduce the effectiveness of the flange
gasket.
(6) Install the front and rear cross-over gaskets
onto the engine (Fig. 37).
(7) 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. 38). The words MANIFOLD SIDE should be vis-
ible on the center of each flange gasket.
(8) Carefully lower intake manifold into position
on the cylinder block and cylinder heads. long studs
at the front and rear of the manifold will help to
align the intake manifold. After intake manifold is in
