Chrysler 300M, Dodge Interpid. Manual — part 260
(2) Align the camshaft sprockets (to reference
mark made upon removal) between the marks on the
rear covers (Fig. 144).
(3) Install the timing belt starting at the crank-
shaft sprocket going in a counterclockwise direction
(Fig. 152). Install the belt around the last sprocket.
Maintain tension on the belt as it is positioned
around the tensioner pulley.
(4)
Holding the tensioner pulley against the belt,
Install the tensioner into the housing and tighten to
28 N·m (250 in. lbs.). Each camshaft sprocket mark
should still fall between the cover marks.
(5)
When tensioner is in place pull retaining pin
to allow the tensioner to extend to the pulley bracket.
(6) Rotate crankshaft sprocket 2 revolutions and
check the timing marks on the camshafts and crank-
shaft. The marks should line up within their respec-
tive locations (Fig. 152). If marks do not line up,
repeat procedure.
(7) Install the front timing belt covers. (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT / CHAIN
COVER(S) - INSTALLATION)
(8) Install the crankshaft vibration damper. (Refer

(10) Install the radiator fan. (Refer to 7 - COOL-
ING/ENGINE/RADIATOR FAN - INSTALLATION)
(11) Install upper radiator crossmember. (Refer to
23 - BODY/EXTERIOR/GRILLE OPENING REIN-
FORCEMENT - INSTALLATION)
(12) Connect negative cable to remote jumper ter-
minal.
INSTALLATION - CAMSHAFT SPROCKETS
CAUTION: The camshaft sprockets are not inter-
changeable from side to side (Fig. 153).
(1) Install camshaft sprockets onto the camshafts.
Install NEW sprocket attaching bolts into place. The
255 mm (10 in.) bolt is to be installed in the left cam-
shaft and the 213 mm (8 3/8 in.) bolt is to be
installed into the right camshaft. Do not tighten
the bolts; tightened at later step. Camshaft
sprocket mark should be positioned between the
marks on the cover at both sprockets (Fig. 154).
(2) Install the timing belt starting first at the
crankshaft sprocket, then to remaining components
in a counterclockwise direction (Fig. 155).
(3) Install the belt around the last sprocket. Main-
tain tension on the belt as it is positioned around the
tensioner pulley. Each camshaft sprockets mark
should still fall between the cover marks (Fig. 155).
NOTE: For timing belt tensioner reset procedure,
(Refer to 9 - ENGINE/VALVE TIMING/TIMING BELT
AND SPROCKETS - TIMING BELT - REMOVAL).

(4) Hold the tensioner pulley against the belt and
install the reset (pinned) timing belt tensioner into
the housing. Tighten attaching bolts to 28 N·m (250
in. lbs.).
(5) Remove tensioner retaining pin to allow the
tensioner to extend to the pulley bracket.
(6) Using a dial indicator, position the number 1
piston at TDC (Fig. 156).
(7) Hold the camshaft sprocket hex with a 36 mm
(1 7/16 in.) wrench and tighten the camshaft bolts to
the following:
• Right side = 102 N·m (75 ft. lbs.) +90° turn
• Left side = 115 N·m (85 ft. lbs.) +90° turn
(8) Remove dial indicator and install spark plug.
(9) Remove Special Tools 6642.
(10) Install cam retainer/thrust plates and O-rings
(Fig. 157). Tighten bolts to 28 N·m (250 in. lbs.).
(11) Install timing belt covers. (Refer to 9 -
