NOTE: When timing belt tensioner is removed from
engine, always store in the vertical (plunger facing
upward) position.
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).
(1) Align the crankshaft sprocket with the TDC
mark on oil pump cover (Fig. 97).
(2) Align the camshaft sprockets (to reference
mark made upon removal) between the marks on the
rear covers (Fig. 94).
(3) Install the timing belt starting at the crank-
shaft sprocket going in a counterclockwise direction
(Fig. 97). 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. 97). If marks do not line up,
repeat procedure.
(7) Install timing belt covers and crankshaft
damper. Refer to procedure in this section.
(8) Install accessory drive belts and cooling fan
module. Refer to COOLING SYSTEM for procedures.
(9) Install upper radiator crossmember. Refer to
BODY for procedure.
(10) Connect negative cable to remote jumper ter-
minal.
(11) Start engine and allow to idle for approxi-
mately 1 minute. If a noise is present from the tim-
ing belt/tensioner, air has possibly entered the
tensioner.
(a) To remove air from tensioner; using a DRB
IIIt, operate the engine at speed of 1600–2000
RPM for 10 minutes. This will purge air from ten-
sioner.
NOTE: If air is present, the timing belt tensioner
will be soft and may generate noise. This noise
should disappear after no more than 15 minutes of
engine running time.
OIL PAN
REMOVAL
(1) Disconnect negative cable from remote jumper
terminal.
(2) Remove dipstick and tube.
(3) Raise vehicle on hoist and drain engine oil.
(4) Remove structural collar from rear of oil pan
and transmission housing (Fig. 98).
(5) Disconnect engine oil cooler line from pan.
