Fig. 14 Cylinder Head Gasket Identification
CAUTION: Ensure that the correct head gaskets are
used and are oriented correctly on cylinder block.
The 3.5L engine head gaskets have perfectly round
combustion sealing rings. The 3.2L engine does
NOT have perfectly round combustion sealing
rings.
(2) Install head gasket over locating dowels.
Ensure the gasket is installed on the correct side of
engine (Fig. 14).
(3) Install cylinder head over locating dowels.
(4) Before installing
threads with engine oil.
(5) Tighten the cylinder head bolts in the sequence
shown in (Fig. 15). Using the 4 step torque-turn
method, tighten according to the following torque val-
ues:
• Step 1: All to 61 N·m (45 ft. lbs.)
• Step 2: All to 88 N·m (65 ft. lbs.)
• Step 3: All (again) to 88 N·m (65 ft. lbs.)
• Step 4: + 90° Turn Do not use a torque
wrench for this step.
(6) Bolt torque after 90° turn should be over 122
N·m (90 ft. lbs.) in the tightening direction. If not,
replace the bolt.

(7) Clean right rear timing belt cover O-ring seal-
ing surfaces and grooves (Fig. 11). Lubricate new
O-rings with Mopar Dielectric Grease or equivalent
to facilitate assembly.
(8) Install rear timing belt covers (Fig. 10) and
(Fig. 11). Tighten bolts to specified torque:
• M10—54 N·m (40 ft. lbs.)
• M8—28 N·m (20 ft. lbs.)
• M6—12 N·m (105 in. lbs.)
(9) Install camshaft sprockets and timing belt.

(12) Install upper and lower intake manifold.
(Refer to 9 - ENGINE/MANIFOLDS/INTAKE MANI-
FOLD - INSTALLATION)
(13) Connect catalytic converter to exhaust mani-
fold using a new V-band clamp(s). Tighten clamp to
10 N·m (100 in. lbs.).
