CAMSHAFT SPROCKETS AND TIMING
PROCEDURE
REMOVAL
CAUTION: The 3.2/3.5L engines are NOT a free-
wheeling design. Therefore, care should be taken
not to rotate the camshafts or crankshaft with the
timing belt removed.
(1) Drain cooling system. Refer to COOLING SYS-
TEM for procedure.
(2) Remove accessory drive belts. Refer to COOL-
ING SYSTEM for procedure.
(3) Remove crankshaft damper.
(4) Remove timing belt covers and timing belt.
CAUTION: When camshaft sprocket bolts are loos-
ened or removed, the camshafts must be re-timed
to the engine. Also, the camshaft sprocket bolts
must NOT be reused. Refer to camshaft timing and
timing belt installation procedure in this section.
(5) Hold camshaft sprocket with 36 mm (1 7/16 in.)
box wrench loosen and remove bolt and washer. To
remove the bolt with engine in the vehicle it may be
necessary to lift that side of the engine because the
right bolt is 213 mm (8 3/8 in.) long and the left bolt
is 255 mm (10.0 in.) long.
(6) Remove camshaft sprocket from camshaft.
Each sprocket has a D shaped hole that allows it to
rotate several degrees in each direction on its shaft.
This design must be timed with the engine to ensure
proper performance of the engine. Refer to camshaft
and timing belt installation in this section for proce-
dures.
TIMING PROCEDURE—3.2/3.5L
CAUTION: The camshaft sprockets are not inter-
changeable from side to side (Fig. 73).
(1) Place crankshaft sprocket to the TDC mark on
the oil pump housing (Fig. 74).
(2) Install a dial indicator in number 1 cylinder to
check TDC of the piston (Fig. 79). Rotate the crank-
shaft until the piston is at exactly TDC.
(3) Install the camshaft alignment Special Tools
6642 to the rear of each cylinder head (Fig. 75).
CAUTION: Compress the tensioner slowly, as dam-
age to the tensioner could result.
(4) Slowly pre-load the tensioner with a vise and
install locking pin (Fig. 76).
NOTE: Once pin is installed, the tensioner must be
stored with the plunger facing upward until it is
ready to be reinstalled.
(5) 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. Camshaft sprocket mark should be posi-
