1. Remove oil pan, oil pump and cylinder head as
previously outlined.
2. For
the cylinder being serviced, turn crankshaft
until piston is at the bottom of the stroke. Place
a cloth on top of the piston.

V-8 ENGINE 6A3-27
3. When finish honing
a cylinder bore to fit a piston,
the hone should be moved up and down at a
sufficient speed to obtain very fine uniform
surface finish marks in a cross-hatch pattern of
approximately
45" to 65" included angle. The
finish marks should be clean but not sharp, free
from imbedded particles and torn or folded
metal.
4. Permanently mark
the piston for the cylinder to
which it has been fitted and proceed to hone
cylinders and fit the remaining pistons.
NOTICE: Handle the pistons with care and do not
attempt to force them through the cylinder until
the cylinder has been honed to correct size as this
type piston can be distorted through careless
handling.
5. Thoroughly
clean the bores with hot water and
detergent. Scrub well with a stiff bristle brush and
rinse thoroughly with hot water. It is extremely
essential that a good cleaning operation be
performed. If any of the abrasive material is
allowed to remain in the cylinder bores, it will
rapidly wear the new rings and cylinder bores in
addition to the bearings lubricated by the
contaminated oil, the bores should be swabbed
and then wiped with a clean dry cloth. Cylinder
should not be cleaned with kerosene or gasoline.
Clean the remainder of the cylinder block to
remove the excess material spread during the
honing operation.
Piston Selection
1. Check USED piston to cylinder bore clearance as
follows:
a. Measure
the "Cylinder Bore Diameter"
with a telescope gage
"2-1/2" (64mm) from
top of cylinder bore").
b. Measure
the
"Piston Diameter" (at skirt
across center line of piston pin).
c. Subtract
piston diameter from cylinder bore
diameter to determine "Piston to Bore
Clearance".
d. Determine if piston to bore clearance is in
the acceptable range.
2. If
used piston is not acceptable, check Piston Size
Chart and determine if a new piston can be
selected to fit cylinder bore within the acceptable
range.
3. If
cylinder bore must be reconditioned, measure
new piston diameter (across center line of piston
pin) then hone cylinder bore to correct clearance
(preferable range).
4. Mark the piston to identify the cylinder for which
it was fitted.
OIL FILTER BYPASS VALVE
Inspection and Replacement
With the oil filter removed, check the spring and
fibre valve for operation. Inspect for a cracked or
broken valve. If replacement is necessary, the oil filter
adapter and bypass valve assembly must be replaced as an

GENERAL DESCRIPnIBN
The cooling system maintains engine temperature
5" below the filler neck which reads, "Important - for
at an efficient level during all engine operating repair see Harrison Service Manual". Service
conditions. When the engine is cold the system cools procedures for the aluminum plastic radiator are
slowly, or not at all, to allow the engine to warm up described in that manual and in this section.
quickly.
The cooling system includes a radiator and
Radiator Cap
recovery sub-system, cooling fan, thermostat and
housing, water pump, and drive belts.
Operation of the cooling system requires proper
functioning of all components. Coolant is drawn from
the radiator by the water pump and circulated through
water jackets in the engine block, intake manifold, and
cylinder
head(s), and then directed back to the radiator
where it's cooled.
This system directs some coolant through hoses
to the heater core, to provide for heating and
defrosting. A recovery bottle is connected to the
radiator to recover coolant displaced by expansion
from high temperatures and maintain correct coolant
level. As the coolant cools and contracts it is drawn
back into the radiator by vacuum.
RADIATOR
A cross-flow radiator is used on all models. Tanks
in this type radiator are located to the right and left of
the core, instead of above and below.
Radiators used with automatic transmissions
have oil coolers with inlet and outlet fittings for
transmission fluid circulation. Cars with manual
transmissions use radiators without oil coolers.
Vehicles equipped with air conditioning use a radiator
with extra cooling capability.
An aluminum-plastic radiator, used on some
models, can be identified by a note on the outlet tank A pressure-vent
cap is used on the cross-flow
radiator to allow a buildup of
103 kPa (15 psi) in the
cooling system. This pressure raises the boiling point
of coolant to approximately 125°C (262°F) at sea level.
Do not remove radiator cap to check engine
coolant level; check coolant visually at the
see-through coolant reservoir. Coolant should
be added only
to the reservoir.
CAUTION: As long as there
is
pressure in the cooling system, the
temperature can be considerably
higher than the boiling temperature
of
the solution in the radiator without
causing the solution to boil. Removal
of the radiator cap while engine is hot
and pressure is high will cause
the
solution to boil instantaneously and
possibly with explosive
force, spewing
the solution over engine, fenders and
person removing cap. If the solution
contains flammable antifreeze, such
as alcohol (not recommended for use
at any time), there is also the
possibility
of causing a serious fire.
The pressure-type radiator filler cap contains a
blow off or pressure valve and a vacuum or
atmospheric valve (Figure
1). The pressure valve is
held against its seat by a spring of pre-determined

ENGINE COOLING BB-7
NOTICE: If recommended quality antifreeze is
used, supplemental inhibitors or additives claiming
to provide increased cooling capability are not
necessary. They may be detrimental to the efficient
operation of the system, and represent an
unnecessary operating expense.
Every 12 months or 15,000 miles, the cooling
system should be serviced as follows;
1. Wash radiator cap and filler neck with clean
water.
2. Check coolant for proper level and freeze
protection.
3. Pressure test system and radiator cap for proper
pressure holding capacity, 103
kPa (15 psi). If
replacement of cap is required, use the proper cap
specified for car model.
4. Tighten hose clamps and inspect all hoses. Replace
hoses whenever cracked, swollen or otherwise
deteriorated.
5. Clean frontal area of radiator core and air
conditioning condenser.
DRAINING AND REFILLING THE COOLING
SYSTEM
Replace hoses every 24 months or 30,000 miles or
earlier if cracked, swollen or otherwise deteriorated.
Every two years or 30,000 miles, whichever first
occurs, the cooling system should be flushed and
refilled using the following recommended procedure:
1. Remove radiator cap, or thermostat housing cap
(VIN
0, J, R and U), when engine is cool by:
a. Slowly
rotating cap counterclockwise to
detent. (Do not press down while rotating.)
b. Wait until any
residual pressure (indicated
by a hissing sound) is relieved.
c. After all hissing ceases, press down on cap
while continuing to rotate
counterclockwise.
CAUTION: To avoid the danger of
being burned, do not remove radiator
cap while engine and radiator are still
hot. Scalding fluid and steam may be
blown out under pressure.
2. Remove the thermostat by using the wire handle
to lift it out of the housing (VIN
0, J, R and U).
3. With the thermostat removed, reinstall the
thermostat housing cap (VIN
0, J, R and U).
4. Open radiator drain valve and block drain plugs
to drain coolant. On VIN R and
9 (P series)
engines, open coolant pipe plugs.
5. Close valve. Reinstall drain plugs, and add
sufficient water to fill system.
6. Run engine, drain and refill the system, as
described in steps
4 and 5 a sufficient number of
times, until the drained liquid is nearly colorless.
Important
BLOCK DRIVE WHEELS, place
transmission in PARK (automatic
transmission) or NEUTRAL (manual
transmission) and set the parking brake. 7.
Allow system to drain completely. Then close
radiator drain valve tightly, and reinstall block
drain plugs.
8. Remove recovery cap leaving hoses in place.
Remove coolant recovery tank and empty of
fluid. Flush tank with clean water, drain and
reinstall.
9. Add sufficient ethylene glycol coolant, meeting
GM specification 1825-M, to provide the
required freezing and corrosion protection
- at
least 50 percent solution -37°C (-34°F). Fill
radiator to the base of the radiator fill neck and
add sufficient coolant to the recovery tank to
raise level to the "FULL" mark. Reinstall
recovery tank cap.
10. Run engine, with radiator cap or thermostat
housing cap removed, until normal operating
temperature is reached. (Radiator upper hose
becomes hot.)
11. With engine idling, add coolant until level
reaches bottom of filler neck and reinstall cap,
making certain arrows line up with overflow tube.
CAUTION: Under some conditions, the
ethylene glycol in engine coolant is
flammable. To help avoid being
burned when adding coolant, DO NOT
spill
it on the exhaust system or hat
engine parts.
It is the owner's responsibility to keep the freeze
protection at a level appropriate to the
temperatures which may occur in the area of
vehicle operation.
a. Maintain
cooling system freeze protection
at
-37°C (-34"F), to ensure protection
against corrosion and loss of coolant from
boiling, even though freezing temperatures
are not expected.
b. Add ethylene glycol base coolant that meets
GM Specification 1825-M, when coolant
additions are required because of coolant
loss, or to provide additional protection
against
freezing at temperatures lower than
-37°C (-34°F).
NOTICE: Alcohol or methanol base coolants, or
plain water, are not recommended at any time.
DRlVE BELT
NOTICE: Routine inspection of the belt may
reveal cracks in the belt ribs. These cracks will
not impair belt performance and therefore should
not be considered a problem requiring belt
replacement. However, the belt should be
replaced if belt slip occurs or if sections of the
belt ribs are missing.
A single (serpentine) belt is used to drive all
engine accessories formerly driven by multiple drive
belts. All belt driven accessories are ridgedly mounted
with belt tension maintained by a spring loaded
tensioner.
The drive belt tensioner has the ability to control
belt tension over a fairly broad range of belt lengths.

ALUMINUM RADIATOR REPAIR
This radiator utilizes an aluminum core with
plastic side tanks. The core and side tanks can be
replaced separately and core repair is easily made with
the hot melt adhesive method. A transaxle oil cooler
is located in one of the side tanks. The oil cooler can
be replaced. The drain cock is located on the lower part
of one of the tanks. The drain cock is also serviceable.
Core
The core is made of aluminum and is of the
crossflow design. It utilizes large tubes that resist
plugging, and repairs to the tubes and core are easily
made using the hot melt adhesive method.
The core is attached to the tanks by clinched tabs
on the core that can be bent back if tank or core
replacement is required.
If the damage to a tube is too severe, a tube can
be blocked or plugged as explained in "Tube Blocking.
" No more than two tubes should ever be blocked on
a core. Also replace the core if more than three tabs are
broken on one side, or if two adjacent tabs are broken.
Tanks
The tanks are attached to the core by the use of
clinched tabs. The clinched tabs can be bent back if the
tanks need to be removed from the core. Bend the tabs
back only enough to remove the tank. Overbending
will weaken the tabs.
A high temperature rubber gasket is used to seal
the mating surface between the core and the tank. (See
Fig. 8). The gasket must be replaced any time a tank
is removed from the core.
Transaxle Oil Cooler
The transaxle oil cooler is located in one of the
radiator side tanks. The oil cooler can be replaced by
removing the tank from the core.
A leaking oil cooler gasket can be replaced
without removing the tank from the core.
Drain Cock
The aluminum/plastic radiator utilizes a two
piece plastic drain cock and a rubber seal. The drain
cock is serviceable (See Fig.
9).
ALUMINUM RADIATOR SERVICE
The aluminum-plastic radiator can be repaired at
the dealership. The following components are easily
replaced:
e Core
e Tanks and gaskets
o Oil coolers and gaskets
e Drain cock and gasket The
tanks cannot be repaired if broken or
cracked. The radiator core can be replaced and the new
core used with the original tanks and oil cooler.
Precautions
As with all cooling system service, take measures
to prevent personal injury and damage to the system.
CAUTION: To help avoid the danger of
being burned, do not remove the
radiator cap while the engine and
radiator are
still hot. Scalding fluid
and steam can be blown out under
pressure if the
cap is taken off too
soon.
NOTICE: DO NOT USE "BOIL OUT" TANKS
OR VATS. Common service methods may
actually destroy an aluminum radiator. Caustic or
lye cleaning solutions must NOT be used for
aluminum radiators.
e Do not open the hood if you can see, or hear,
steam or coolant escaping from the engine
compartment.
e Do not remove radiator cap if radiator feels
warm.
e Do not remove the radiator cap or coolant
recovery tank cap if the coolant in the recovery
tank looks like it is boiling.
Wear eye protection.
e Wear gloves to protect your hands against
excessive heat, or the effects of chemicals on your
skin.
o Prevent dirt and water from entering the
transmission oil cooler.
e Do not use boil-out tanks, or vats, or other tanks
that have been used for copper and brass
radiators. The flux, acid, and caustic cleaners
remaining in these tanks will attack the
aluminum and cause radiator failure.
A separate
test tank containing clean water is strongly
recommended for servicing aluminum-plastic
radiators.
RIOTICE: Never use shop air that is not regulated
at
20 psi (138 kPa) to pressure test radiator.
Pressures over
20 psi (138 kPa) will damage the
radiator.
DIAGNOSIS
Leak Testing
Some core leaks can be detected by merely adding
water to the radiator. It is helpful to clean the core so
that the damaged area can be more easily found.
