CAMSHAFT
REMOVAL
Camshafts are serviced from the rear of the cylin-
der head. The cylinder head must be removed.
(1) Remove Camshaft Sprocket. Refer to Camshaft
Sprocket Removal in this section.
(2) Remove cylinder head. Refer to Cylinder Head
Removal in this section.
(3) Mark the rocker arm and shaft assembly before
removal. Remove the rocker arm and shaft assembly
from the head.
(4) Remove the rear camshaft cover and O-ring
from head.
CAUTION:
Be careful not to Nick or Scratch the
journals when removing the camshaft.
(5) Carefully remove the camshaft from the rear of
the cylinder head.
INSTALLATION
(1) Lubricate camshaft journals and cam with
clean engine oil and install camshaft into cylinder
head.
(2) Install the rocker arm assembly. Refer to pro-
cedure outlined in this section.
NOTE: Refer to Camshaft Sprocket and Timing Pro-
cedure to complete camshaft installation.
CAMSHAFT SPROCKETS AND TIMING PROCEDURE
REMOVAL
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 outlined in this
section.
(1) 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.
(2) 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 outlined in this section
for procedure.

TIMING PROCEDURE—3.2L
CAUTION:
The camshaft sprockets are not inter-
changeable from side to side (Fig. 48).
(1) Place crankshaft sprocket to the TDC mark on
the oil pump housing (Fig. 49).
(2) Install a dial indicator in number 1 cylinder to
check TDC of the piston (Fig. 54). Rotate the crank-
shaft until the piston is at exactly TDC. This is
important for good engine performance.
(3) Install the camshaft alignment Special Tools
6642 to the rear of each cylinder head (Fig. 50).
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. 51).
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-
tioned between the marks on the cover (Fig. 52) at
both sprocket.
(6) Install the timing belt starting at the crank-
shaft sprocket going in a counterclockwise direction
(Fig. 53). Install the belt around the last sprocket.
Maintain tension on the belt as it is positioned

around the tensioner pulley. Each camshaft sprockets
mark should still fall between the cover marks.
(7) Holding the tensioner pulley against the belt,
install the tensioner into the housing and tighten to
28 N·m (250 in. lbs.).
(8) When tensioner is in place pull retaining pin to
allow the tensioner to extend to the pulley bracket.
(9) With number 1 piston at TDC (Fig. 54), hold
the camshaft sprocket hex with a 36 mm (1 7/16 in.)
wrench and tighten the camshaft bolts to 102 N·m
(75 ft. lbs.) plus a 90 degree turn for the Right side
and 115 N·m (85 ft. lbs.) plus a 90 degree turn for
the Left side.
(10) Remove dial indicator and install spark plug.
(11) Remove camshaft alignment Special Tools
6642 and install cam covers and O-rings. Tighten fas-
teners to 28 N·m (250 in. lbs.).
(12) Install timing belt covers. Refer to Timing
Belt Cover procedures outlined in this section.
(13) Install crankshaft damper.
(14) Install accessory drive belts. Refer to Group
07, Cooling System for procedure.
(15) Fill cooling system. Refer to Group 07, Cooling
System for procedure.
(16) Start engine and allow to idle for approxi-
mately 1 minute. Then, operate the engine at speed
of 1200 – 1500 RPM for 5 minutes. This will help to
bleed out any possible air in the timing belt ten-
sioner.
ROCKER ARM AND SHAFT ASSEMBLY
CAUTION: The rocker arm shafts are hollow and
are used as lubrication oil passages. The rocker
arm and shaft assembly on the right side of the
engine has an oil passage hole from the cylinder head
to the third rocker shaft support. The rocker arm shaft
assembly on the left side of the engine has an oil pas-
sage hole from the cylinder head to the second rocker
shaft support.
REMOVAL
(1) Remove cylinder head covers. Refer to proce-
dure outlined in this section.
(2) Identify the rocker arm assembly and rocker
arms before disassembly (Fig. 55).

(3) Remove rocker arm assembly bolts.
(4) Remove rocker arm assembly.
NOTE: To prevent air ingestion into lash adjusters,
avoid turning rocker arm assembly upside down.
CAUTION: Do not allow rocker arm assembly to
rest on lash adjusters, as damage may occur to
lash adjusters and/or plastic retainers.
DISASSEMBLY
(1) Remove dowel pin using a 4 mm screw, nut,
spacer, and washer installed into the pin (Fig. 56).
Tighten the screw into the pin, then loosen the nut
on the screw. This will pull the dowel out of the shaft
support. Do not reuse dowel pins. Remove the rocker
arms and pedestals in order.
(2) Check the rocker arm mounting portion of the
shafts for wear or damage. Replace if damaged or
heavily worn.
(3) Check shaft oil holes for clogging with small
wire, clean as required.
ASSEMBLY
CAUTION: New dowel pins must be installed during
assembly.
(1) Install the rocker arms, and pedestals onto the
shaft.
NOTE: The notches on the rocker shafts face up
(Fig. 55). Notches on the right cylinder bank face
towards rear of engine. Notches on left cylinder
bank face toward front of engine.
(2) Install dowel pins (Fig. 57). Dowel pins pass
through the pedestal into the exhaust rocker shafts.
Dowel pins should be pressed in until they bottom-
out against the rocker shaft in the pedestal.
CAUTION: Inspect all lash adjuster plastic retaining
caps for proper retention before installation.
INSTALLATION
NOTE: Rocker arm and shaft assembly can be
installed either prior to or after cylinder head instal-
lation.
(1) Rotate camshafts to the position shown in (Fig.
58). With the camshafts in these positions the lobes
are in a neutral position (no load to the valve). This
will allow the rocker arm shaft assembly to be tight-
ened into position with little or no valve spring load
on it.
(2) Install the rocker arm and shaft assembly
making sure that the identification marks face
toward the front of engine for left head and toward
the rear of the engine for right head.
(3) Tighten bolts in sequence to 31 N·m (275 in.
lbs.) (Fig. 59).
VALVE STEM SEALS OR VALVE SPRINGS—IN
VEHICLE
(1) Perform fuel system pressure release procedure
before attempting any repairs. Refer to Group 14,
Fuel System for procedure.
(2) Disconnect negative battery cable.
(3) Remove air cleaner housing and hose assembly.
