CAL/CHARGING/GENERATOR - REMOVAL).
(48)
Remove the water pump pulley attaching bolts
and position pulley between pump hub and housing.
(49) Disconnect the oil pressure switch electrical
connector.
(50) Disconnect wiring harness support clip from
engine oil dipstick tube.
(51) Install Special Tools 6912 and 8444 Adapters
on the right side (rear) of engine block (Fig. 9).
(52) Lower the vehicle.
(53) Remove the power steering pump and set
aside.
(54) Raise vehicle enough to allow engine dolly
Special Tool 6135 and cradle Special Tool 6710 withpost Special Tool 6848 and adaptor Special Tool 6909
to be installed under vehicle (Fig. 12).
(55) Loosen cradle/post mounts to allow movement
for positioning posts into locating holes on the engine
(Fig. 10) and (Fig. 11). Slowly lower vehicle and posi-
tion cradle/post mounts until the engine is resting on
posts. Tighten all cradle/post mounts to cradle frame.
This will keep mounts from moving when removing
or installing engine and transmission.
(56) Lower vehicle so the weight ofONLY THE
ENGINE AND TRANSMISSIONis on the cradle.
(57) Install and secure the safety straps to the cra-
dle fixture and around the engine (Fig. 12).
(58) Remove the engine right side mount to engine
attaching bolts (Fig. 13).
(59) Remove the left mount through bolt (Fig. 14).
(60) Raise vehicle slowly. It is necessary to move
the engine/transmission assembly with the dolly to
allow for removal around body flanges.

INSTALLATION - ENGINE ASSEMBLY
(1) Position engine and transmission assembly
under vehicle. Slowly lower the vehicle down over the
engine and transmission. It is necessary to move the
engine/transmission assembly with the dolly for
clearance around body flanges.
(2)
Align engine and transmission mounts to attach-
ing points. Install mounting bolts at the right engine
mount (Fig. 13) and left transmission mount (Fig. 14).
(3) Remove the safety straps from around engine.
(4) Slowly raise vehicle enough to remove the
engine dolly and cradle Special Tools 6135, 6710,
6848 and 6909 (Fig. 12).
(5) Remove Special Tools 6912 and 8444 (Fig. 9).
(6) Lower the vehicle.
(7) Install power steering pump and pressure line
support.

DURE). Be careful not to gouge or scratch the alumi-
num head sealing surface.
Clean all engine oil passages.
INSPECTION
(1) Before cleaning, check for leaks, damage and
cracks.
(2) Clean cylinder head and oil passages.
(3) Check cylinder head for flatness (Fig. 19).
(4) Cylinder head must be flat within:
²Standard dimension = less than 0.05 mm (0.002
inch.)
²Service Limit = 0.2 mm (0.008 inch.)
²Grinding Limit = Maximum of 0.2 mm (0.008
inch.) is permitted.
CAUTION: 0.20 mm (0.008 in.) MAX is a combined
total dimension of the stock removal limit from cyl-
inder head and block top surface (Deck) together.
INSTALLATION - CYLINDER HEAD
(1) Clean all sealing surfaces of engine block and
cylinder heads. (Refer to 9 - ENGINE - STANDARD
PROCEDURE)
(2) Position new gasket(s) on engine block (Fig.
20). The left bank gasket is identified with the ªLºstamped in the exposed area of the gasket located at
front of engine (shown in (Fig. 20)). The right bank
gasket is identified with a ªRº stamped in the
exposed area of the gasket also, but is located at the
rear of the engine.
(3)The cylinder head bolts are torqued using
the torque yield method, they should be exam-
ined BEFORE reuse. If the threads are necked
down, the bolts must be replaced(Fig. 21).
(4) Necking can be checked by holding a scale or
straight edge against the threads. If all the threads
do not contact the scale the bolt should be replaced.
(5)
Tighten the cylinder head bolts 1±8 in the
sequence shown in (Fig. 22). Using the 4 step torque
turn method, tighten according to the following values:
²Step 1: Bolts1±8to61N´m(45ft.lbs.)
²Step 2: Bolts1±8to88N´m(65ft.lbs.)
²Step 3: Bolts1±8(again) to 88 N´m (65 ft. lbs.)
²Step 4: Bolts1±8turn an additional 1/4 Turn.
(Do not use a torque wrench for this step.)

NOTE: Bolt torque after 1/4 turn should be over 122
N´m (90 ft. lbs.). If not, replace the bolt.
(6) Inspect push rods and replace worn or bent
rods.
(7) Install the push rods.
(8) Install the rocker arm and shaft assemblies.
(Refer to 9 - ENGINE/CYLINDER HEAD/ROCKER
ARMS - INSTALLATION)
(9) Install the cylinder head covers. (Refer to 9 -

COVER(S) - INSTALLATION)
(10) Install the exhaust manifolds. (Refer to 9 -
ENGINE/MANIFOLDS/EXHAUST MANIFOLD -
INSTALLATION)
(11) Install new O-ring on dipstick tube. Install
dipstick tube assembly (Fig. 18).
(12) Install the spark plugs.
(13) Install upper and lower intake manifolds.
(Refer to 9 - ENGINE/MANIFOLDS/INTAKE MANI-
FOLD - INSTALLATION)
(14) Fill the cooling system. (Refer to 7 - COOL-
ING - STANDARD PROCEDURE)
(15) Connect negative cable to battery.
CYLINDER HEAD COVER(S)
DESCRIPTION
The cylinder head covers are made of stamped
steel. The covers are sealed with steel reinforced sil-
icon rubber gaskets. The cylinder head cover uses
rubber isolators at each fastener location (Fig. 23).
NOTE: Due to the tight packaging near the cylinder
head covers, which makes spill clean-up difficult, a
spill during an engine oil change may be misinter-
preted as an oil leak. When investigating an oil leak
in the location of the cylinder head covers and
intake manifold, follow the procedure found in Oil
Leak Diagnosis (Refer to 9 - ENGINE - DIAGNOSIS
AND TESTING) for determining the source of a leak.
CYLINDER HEAD COVER -
RIGHT
REMOVAL
(1) Disconnect negative cable from battery.
(2) Remove the wiper module. (Refer to 8 - ELEC-
TRICAL/WIPERS/WASHERS/WIPER MODULE -
REMOVAL)
(3) Disconnect spark plug wires from plugs.
(4) Disconnect PCV hose from cylinder head cover
(Fig. 24).
(5) Remove cylinder head cover bolts.
(6) Remove cylinder head cover and gasket (Fig.
23).
