CAMSHAFT AND CRANKSHAFT TIMING
PROCEDURE AND BELT INSTALLATION
ÐSOHC ENGINE
(1) When tensioner is removed from the engine it
is necessary to compress the plunger into the ten-
sioner body.
(2) Place the tensioner into a vise equipped with
soft jaws and slowly compress the plunger (Fig. 47).
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.
(3) When plunger is compressed into the tensioner
body install a 1.9 mm (5/64) Allen wrench or pin

through the body and plunger to retain plunger in
place until tensioner is installed.
(4) 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. 48).
(5) Set camshaft to TDC by aligning mark on
sprocket with the arrow on the rear of timing belt
cover (Fig. 49).
(6) Move crankshaft to 1/2 mark before TDC (Fig.
50) 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. 51).
(10) With torque being applied to the tensioner
pulley move the tensioner up against the tensioner

²Connect DRB scan tool to the data link (diagnos-
tic) connector. This connector is located in the pas-
senger compartment; at the lower edge of instrument
panel; near the steering column.
²Turn the ignition switch on and access the ªmis-
cellaneousº screen.
