torque.
(6) Install the cooling fan.
(7) Connect the battery negative cable.
TIMING CHAIN COVER
(1) Disconnect the negative cable from the battery.
(2) Drain cooling system (refer to Group 7, Cooling
System).
(3) Remove the serpentine belt (refer to Group 7,
Cooling System).
(4) Remove water pump (refer to Group 7, Cooling
System).
(5) Remove power steering pump (refer to Group
19, Steering).
(6) Remove vibration damper.
(7) Remove fuel lines (refer to Group 14, Fuel Sys-
tem).
(8) Loosen oil pan bolts and remove the front bolt
at each side.
(9) Remove the cover bolts.
(10) Remove chain case cover and gasket using
extreme caution to avoid damaging oil pan gasket.
(11) Place a suitable tool behind the lips of the oil
seal to pry the oil seal outward. Be careful not to
damage the crankshaft seal surface of cover (Fig. 53).
INSTALLATION
(1) Be sure mating surfaces of chain case cover
and cylinder block are clean and free from burrs.
(2) The water pump mounting surface must be
cleaned.(3) Using a new cover gasket, carefully install
chain case cover to avoid damaging oil pan gasket.
Use a small amount of Mopar Silicone Rubber Adhe-
sive Sealant, or equivalent, at the joint between tim-
ing chain cover gasket and the oil pan gasket. Finger
tighten the timing chain cover bolts at this time.
(4) Place the smaller diameter of the oil seal over
Front Oil Seal Installation Tool 6635 (Fig. 54). Seat
the oil seal in the groove of the tool.
(5) Position the seal and tool onto the crankshaft
(Fig. 55).
(6) Tighten the 4 lower chain case cover bolts to
13N´m (10 ft.lbs.) to prevent the cover from tipping
during seal installation.
(7) Using the vibration damper bolt, tighten the
bolt to draw the seal into position on the crankshaft
(Fig. 56).
(8) Loosen the 4 bolts tightened in step 4 to allow
realignment of front cover assembly.
(9) Tighten chain case cover bolts to 41 N´m (30 ft.
lbs.) torque. Tighten oil pan bolts to 24 N´m (215 in.
lbs.) torque.

installation tool.
(11) Install vibration damper.(12) Install water pump and housing assembly
using new gaskets (refer to Group 7, Cooling Sys-
tem). Tighten bolts to 41 N´m (30 ft. lbs.) torque.
(13) Install power steering pump (refer to Group
19, Steering).
(14) Install the serpentine belt (refer to Group 7,
Cooling System).
(15) Install the cooling system fan. Tighten the
bolts to 23 N´m (17 ft. lbs.) torque.
(16) Position the fan shroud and install the bolts.
Tighten the bolts to 11 N´m (95 in. lbs.) torque.
(17) Fill cooling system (refer to Group 7, Cooling
System for the proper procedure).
(18) Connect the negative cable to the battery.
TIMING CHAIN
REMOVAL
(1) Disconnect battery negative cable.
(2) Remove Timing Chain Cover. Refer to Timing
Chain Cover in this section for correct procedure.
(3) Re-install the vibration damper bolt finger
tight. Using a suitable socket and breaker bar, rotate
the crankshaft to align timing marks as shown in
(Fig. 57).
(4) Remove camshaft sprocket attaching bolt and
remove timing chain with crankshaft and camshaft
sprockets.
INSTALLATION
(1) Place both camshaft sprocket and crankshaft
sprocket on the bench with timing marks on exact
imaginary center line through both camshaft and
crankshaft bores.
(2) Place timing chain around both sprockets.
(3) Turn crankshaft and camshaft to line up with
keyway location in crankshaft sprocket and in cam-
shaft sprocket.
(4) Lift sprockets and chain (keep sprockets tight
against the chain in position as described).
(5) Slide both sprockets evenly over their respec-
tive shafts and use a straightedge to check alignment
of timing marks (Fig. 57).
(6) Install the camshaft bolt. Tighten the bolt to 68
N´m (50 ft. lbs.) torque.
(7) Check camshaft end play. The end play should
be 0.051-0.152 mm (0.002-0.006 inch) with a new
thrust plate and up to 0.254 mm (0.010 inch) with a
used thrust plate. If not within these limits install a
new thrust plate.
(8) Install the timing chain cover.
CAMSHAFT
NOTE: The camshaft has an integral oil pump and
distributor drive gear (Fig. 58).
