(4) Remove Intake Manifold. Refer to Group 11,
Exhaust System and Intake Manifold for removal
procedure.
(5) Remove cylinder head covers and spark plugs.
Refer to this section for procedure.
(6) Remove rocker arm and shaft assembly. Refer
to this section for procedure.
(7) Rotate the crankshaft clockwise, until the num-
ber 1 piston is at TDC (Top Dead Center) on the com-
pression stroke.
(8) With air hose attached to spark plug adapter
installed in number 1 spark plug hole, apply 620.5 to
689 kPa (90 to 100 psi) air pressure. This is to hold
valves into place while servicing components.
(9) Using Tool MD 998772A with adapter 6527 or
equivalent, compress valve spring and remove valve
locks, retainer, and valve spring.
(10) Remove valve stem seals by using a valve
stem seal tool (Fig. 60).
(11) The valve stem seal/valve spring seat should
be pushed firmly and squarely over the valve guide
using the valve stem as guide. Do Not Force seal
against top of guide. When installing the valve
retainer locks, compress the spring only enough to
install the locks.
CAUTION: Do not remove garter spring around the
seal at the top of the valve stem seal (Fig. 61).
(12) Follow the same procedure on the remaining 5
cylinders using the firing sequence 1-2-3-4-5-6. Make
sure piston in cylinder is at TDC on the valve
spring that is being covered.
(13) Remove spark plug adapter tool.
(14) Remove Special Tool MD 998772A and install
rocker arm assembly. Refer to procedure outlined in
this section.
(15) Install cylinder head covers. Refer to proce-
dure outline in this section.
(16) Install ignition coils and connect all electrical
connectors.
(17) Install intake manifold plenum. Refer to
Group 11, Exhaust System and Intake Manifold.
(18) Connect negative cable.

REMOVAL AND INSTALLATION (Continued)
VALVE AND VALVE SPRINGS
REMOVAL
(1) With cylinder head removed, compress valve
springs using the Valve Spring Compressors shown
in (Fig. 62).
(2) Remove valve retaining locks, valve spring
retainers, valve springs and valve spring seat/stem
seal assembly.
(3) Before removing valves, remove any burrs
from valve stem lock grooves to prevent dam-
age to the valve guides. Identify valves to insure
installation in original location.
INSTALLATION
(1) Coat valve stems with clean engine oil and
insert them in cylinder head.
(2) If valves or seats have been reground, check
valve tip height (A) (Fig. 63). If valve tip height is
greater than 43.65 mm (1.7185 in.) intake or 45.98
mm (1.8102 in.) exhaust, grind valve tip until within
specifications. Make sure measurement is taken from
cylinder head surface to the top of valve stem.
(3) Install valve seal/spring seat assembly over
valve guides on all valve stems (Fig. 64). Ensure that
the garter spring is intact around the top of the rub-
ber seal. Install valve springs, valve retainers.
(4) Compress valve springs with a valve spring
compressor install locks and release tool. If valves
and/or
seats
are
reground,
measure
the
installed height of springs (B) (Fig. 63), make
sure measurements are taken from top of
spring seat to the bottom surface of spring
retainer. If height is greater than 38.75 mm (1.5256
inches), install a .762 mm (0.030 inch.) spacer in
head counterbore under the valve spring seat to
bring spring height back within specification.
TIMING BELT COVERS
REMOVAL
(1) Disconnect negative cable from remote jumper
terminal.
(2) Remove upper radiator crossmember. Refer to
Group 23, Body for procedure.
(3) Remove fan module. Refer to Group 07, Cooling
System for procedure.
(4) Remove the accessory drive belts. Refer to
Group 07, Accessory Drive System for service proce-
dure.
(5) Use Special Tool 8191 to hold crankshaft
damper while removing center bolt.
(6) Remove crankshaft damper using Special Tools
1023 and C-4685-C2 (Fig. 65).

REMOVAL AND INSTALLATION (Continued)
(7) Remove the lower belt cover located behind the
crankshaft damper (Fig. 66).
(8) Remove the stamped steel cover (Fig. 66). Do
not remove the sealer on the cover, it is reus-
able (Fig. 67). If some sealer is missing use Mopar
t
Silicone Rubber Adhesive Sealant or equivalent to
replace the missing sealer.
(9) Remove the left cast cover (Fig. 66).
INSTALLATION
(1) Install the left cast cover and accessory belt
tensioner pulley and bracket.
(2) Install the right stamped steel cover.
(3) Install the lower cover.
(4) Install the crankshaft damper using Special
Tools C-4685-C1 Bolt (5.9 in.) and 6792-1. Install cen-
ter bolt, and while holding damper with Special Tool
8191, tighten center bolt to 115 N·m (85 ft. lbs.).
(5) Install the fan module and upper radiator
crossmember.
(6) Connect negative cable to remote jumper termi-
nal.
TIMING BELT
REMOVAL
CAUTION: The following procedure can only be
used when the camshaft sprockets HAVE NOT
BEEN LOOSENED or removed from the camshafts.
Refer to Camshaft Sprocket and Engine Timing in
this Section, if sprocket(s) or camshaft(s) have
been loosened or removed.
CAUTION: The 3.2L is NOT a free–wheeling engine.
Care should be taken not to rotate the camshafts or
crankshaft with the timing belt removed.
(1) Disconnect negative cable from remote jumper
terminal.
(2) Remove upper radiator crossmember. Refer to
Group 23, body for procedure.
(3) Disconnect fan module electrical connector.
(4) Remove fan module. Refer to Group 07, Cooling
System for procedure.
(5) Remove accessory drive and air conditioning
drive belts. Refer to Group 07, Cooling System for
procedure.
(6) Remove crankshaft damper and front timing
belt covers. Refer to procedure outlined in this sec-
tion.
(7) Mark belt running direction, if timing belt is to
be reused.
CAUTION: When aligning timing marks, always
rotate engine by turning the crankshaft. Failure to
do so will result in valve and/or piston damage.

REMOVAL AND INSTALLATION (Continued)
(8) Rotate engine clockwise until crankshaft mark
aligns with the TDC mark on oil pump housing and
the camshaft sprocket timing marks are between the
marks on the rear covers (Fig. 68).
CAUTION: Align the camshaft sprockets between
the marks on rear belt covers before timing belt
removal or damage to valve and/or pistons could
occur.
(9) Using a ink or paint marker; mark the exact
position of the camshaft sprocket timing mark rela-
tive to the two timing marks on the rear timing
cover.
NOTE: When timing belt tensioner is removed from
engine, always store in the vertical (plunger facing
upward) position.
(10) Remove the timing belt tensioner (Fig. 69)
and remove timing belt.
TIMING BELT TENSIONER
(11) When tensioner is removed from the engine it
is necessary to compress the plunger into the ten-
sioner body.
CAUTION: Compress the tensioner slowly, as dam-
age to tensioner could result.
(12) Place the tensioner into a vise and SLOWLY
compress the plunger (Fig. 70). Total bleed down of
tensioner should take about 5 minutes.
CAUTION: Index the tensioner in the vise the same
way it is installed on the engine. This is to ensure
proper pin orientation when tensioner is installed
on the engine.
(13) When plunger is compressed into the ten-
sioner body install a pin through the body and
plunger to retain plunger in place until tensioner is
installed.
NOTE: When the tensioner is removed from the
engine, always store with the plunger pointing
upward.
INSTALLATION
CAUTION:
This procedure can only be used when
the camshaft sprockets HAVE NOT BEEN LOOS-
ENED or removed from the camshafts.
CAUTION: If camshafts have moved from the tim-
ing marks, always rotate camshaft towards the
direction nearest to the timing marks (DO NOT
TURN CAMSHAFTS A FULL REVOLUTION OR DAM-
AGE to valves and/or pistons could result).
