(5) Set camshaft to TDC by aligning mark on
sprocket with the arrow on the rear of timing belt
cover (Fig. 36).
(6) Move crankshaft to 1/2 mark before TDC (Fig.
37) for belt installation.
(7) Install timing belt. Starting at the crankshaft,
go around the water pump sprocket and then around
the camshaft sprocket.(8) Move crankshaft sprocket to TDC to take up
belt slack. Install tensioner to block but do not
tighten fasteners.
(9) Using a torque wrench on the tensioner pulley
apply 28 N´m (250 in. lbs.) of torque (Fig. 38).
(10) With torque being applied to the tensioner
pulley move the tensioner up against the tensioner
pulley bracket and tighten fasteners to 31 N´m (275
in. lbs.) (Fig. 38).
(11) Pull tensioner plunger pin. Pretension is cor-
rect when pin can be removed and installed.
(12) Rotate crankshaft 2 revolutions and check the
alignment of the timing marks (Fig. 38).
(13) Install front half of timing cover.

(14) Install crankshaft damper using M12-1.75 x
150 mm bolt, washer, thrust bearing and nut from
Special Tool 6792. Install crankshaft damper bolt and
tighten to 142 N´m (105 ft. lbs.) (Fig. 39).
(15) Install accessory drive belts. Refer to Group 7,
Cooling System Accessory Drive section for proce-
dure.
(16) Perform camshaft and crankshaft timing
relearn. Refer to Group 25, Emission Control Sys-
tems for procedure.

²Remove number one spark plug.
²Using a dial indicator, set number one cylinder
to TDC on the compression stroke.
²Remove the access plug from the outer timing
belt cover (Fig. 28).
²Check the timing mark on the camshaft
sprocket, it should align with the arrow on the rear
belt cover (Fig. 29).
REMOVALÐTIMING BELT
(1) Remove accessory drive belts. Refer to Group 7,
Cooling System for procedure outlined in that sec-
tion.
(2) Raise vehicle on a hoist and remove right inner
splash shield (Fig. 42).
(3) Remove crankshaft damper bolt. Remove
damper using the large side of Special Tool 1026 and
insert 6827-A (Fig. 30).
(4) Lower vehicle and place a jack under engine.
(5) Remove right engine mount. Refer to procedure
outlined in this section.
(6) Remove right engine mount bracket (Fig. 44).
(7) Remove front timing belt cover (Fig. 31).CAUTION: Align camshaft and crankshaft timing
marks before removing the timing belt by rotating
the engine with the crankshaft.
(8) Inserta8mmAllen wrench into the belt ten-
sioner. Before rotating the tensioner insert the long
end of a 1/8º or 3 mm Allen wrench into the pin hole
on the front of the tensioner (Fig. 33). Rotate the ten-
sioner counterclockwise with the Allen wrench, while
pushing in lightly on the 1/8 in. or 3 mm Allen
wrench, until it slides into the locking hole.
(9) Remove timing belt.
CAUTION: Do not rotate the camshafts once the
timing belt has been removed or damage to valve
components may occur.
CAMSHAFT AND CRANKSHAFT TIMING PROCEDURE AND
BELT INSTALLATION ÐSOHC ENGINE
(1) Set crankshaft sprocket to TDC by aligning the
sprocket with the arrow on the oil pump housing,
then back off to 3 notches before TDC (Fig. 35).
(2) Set camshaft to TDC by aligning mark on
sprocket with the arrow on the rear of timing belt
cover (Fig. 36).
(3) Move crankshaft to 1/2 mark before TDC (Fig.
37) for belt installation.
(4) Install timing belt. Starting at the crankshaft,
go around the water pump sprocket and then around
the camshaft sprocket.
(5) Move crankshaft sprocket to TDC to take up
belt slack.
(6) Remove the pin or 1/8º or 3 mm Allen wrench
from belt tensioner.
(7) Rotate crankshaft 2 revolutions and check the
alignment of the timing marks (Fig. 50).
(8) Install front half of timing cover.
(9) Install engine mount bracket.
(10) Install Right engine mount. Refer to proce-
dure outlined in this section.
(11) Remove jack from under engine.
(12) Install crankshaft damper using M12-1.75 x
150 mm bolt, washer, thrust bearing and nut from
Special Tool 6792. Install crankshaft damper bolt and
tighten to 142 N´m (105 ft. lbs.) (Fig. 39).
(13) Install accessory drive belts. Refer to Group 7,
Cooling System Accessory Drive section for proce-
dure.
(14) Raise vehicle on hoist and install right inner
splash shield.
(15) Perform camshaft and crankshaft timing
relearn procedure as follows:
²Connect the DRB scan tool to the data link
(diagnostic) connector. This connector is located in
the passenger compartment; at the lower edge of
instrument panel; near the steering column.
