(13) Position the fan shroud and install the bolts.
Tighten the bolts to 11 N·m (95 in. lbs.) torque.
(14) Fill cooling system (Refer to 7 - COOLING -
STANDARD PROCEDURE).
(15) Connect the negative cable to the battery.
(16) Start engine check for leaks.
TIMING BELT/CHAIN AND
SPROCKETS
REMOVAL
(1) Disconnect battery negative cable.
(2) Remove Timing Chain Cover (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT / CHAIN
COVER(S) - REMOVAL).
(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. 73).
(4) Remove camshaft sprocket attaching bolt and
remove timing chain with crankshaft and camshaft
sprockets.
INSPECTION—MEASURING TIMING CHAIN
STRETCH
(1) Place a scale next to the timing chain so that
any movement of the chain may be measured.

(2) Place a torque wrench and socket over cam-
shaft sprocket attaching bolt. Apply torque in the
direction of crankshaft rotation to take up slack; 41
N·m (30 ft. lbs.) torque with cylinder head installed
or 20 N·m (15 ft. lbs.) torque with cylinder head
removed. With a torque applied to the camshaft
sprocket bolt, crankshaft should not be permitted to
move. It may be necessary to block the crankshaft to
prevent rotation.
(3) Hold a scale with dimensional reading even
with the edge of a chain link. With cylinder heads
installed, apply 14 N·m (30 ft. lbs.) torque in the
reverse direction. With the cylinder heads removed,
apply 20 N·m (15 ft. lbs.) torque in the reverse direc-
tion. Note the amount of chain movement (Fig. 74).
