Installation Instructions
Attention:
The Technician must identify and
repair the problem(s) that caused
the original Engine replacement, or
additional Engine failures not
covered under Warranty may occur.
Diagnosis of Proper operation of the
FUEL, LUBRICATION, COOLING,
IGNITION, INDUCTION, EXHAUST, E.G.R.,
VACUUM and ELECTRICAL SYSTEMS is
mandatory.
WARNING:
When cleaning Gasket Sealing
Surfaces on the REMANUFACTURED
Engines and/or Cleaning Parts from
the Failed Engine to be reused, the
use of SURFACE CONDITIONING DISCS
that contain abrasives such as
ALUMINUM OXIDE may cause Infant
Bearing Failure.
THE USE OF SURFACE CONDITIONING
DISCS IS STRICTLY FORBIDDEN,
i.e., SCOTCH BRITE,™ ROLO BRISTLE
DISCS,™ Soc Att,™ ABRASIVE DISCS.
If the original Engine failed either
catastrophically or due to Bearing
Failure, the Engine Oil Cooler must
be replaced, if the vehicle is so
equipped, and the Oil Lines must be
removed from the vehicle and
thoroughly flushed or replaced.
Warranty Data shows that more than
half of all warranty claims for
infant failures are associated with
lack of proper Lubrication.
ENGINE INSTALLATION:
Before installing this engine,
verify that you have the correct
engine for your application. Refer
to the appropriate Vehicle Chassis
Service Manual for proper repair
procedures and specifications (i.e.
fastener torque, torque sequencing,
ignition timing, valve adjustments,
coolant fill, air purge and fluid
volumes).
1. Seals, Gaskets & Components:
After removing the old engine, use
new seals, gaskets, oil pump,
filters (oil, air, fuel) and spark
plugs. Transfer all necessary
components to the replacement
service engine. Prior to
transferring, thoroughly clean and
inspect or replace all parts you
will be transferring such as the Oil
Pan, Intake Manifold, Front Cover,
Valve Covers, Distributor Assemble,
Ignition Wires, Harmonic Balancer
front oil seal surface, Oil Filter
Adapter and Lines, Oil Pick-Up Tube,
and Fuel System. (This will avoid
possible contamination or
installation of worn or damaged
parts and/or less than normal
performance that could damage the
service engine). On vehicles where
the engine has been damaged due to
overheating, check and recondition
or replace the Radiator, Radiator
Cap, Water Pump, Coolant Hoses,
Thermostat, Fan Clutch and Cooling
Fan Sensors, Always add Cooling
System Tabs. Cooling System Tabs aid
in sealing porosity in aluminum and
remove silicates from the Water Pump
Shaft that form from the coolant, to
Extend Water Pump Seal life.
2. Pre-Lube:
For applications that do not get
shipped with sheet metal: Prior to
installing the oil pan and with the
engine upside down on an engine
stand, pour ¼ can of GM ENGINE OIL
SUPPLEMENT (GM P.N. 1052367) over
the crank and bearing cap
assemblies. Fill the oil pump prior
to installation. Install the oil pan
and rotate the engine on the engine
stand right side up. Pour the rest
of the E.O.S. over the rocker
Assemblies and cam shaft assembly
subsequent to installing the intake
and rocker covers. After installing
the engine in the vehicle, add an
API Certified Engine Oil. Refer to
your service manual for the proper
grade, volume, and seasonal
viscosity.
3. Oil Pump Prime Procedure:
Where applicable use a drill motor
attached to the oil pump through the
distributor hole. Turn the oil pump
at 200 to 500 rpm for an additional
two minutes after the normal oil
pressure is achieved. This is to
flush any debris from the engine
without a load on the crank bearings
while maximum bearing clearances are
present. Coat the Distributor gear
with E.O.S. subsequent to
Distributor installation. For
applications without distributor
drive-type oil pump, use a Pressure
Pre-Luber following the
manufacturer's recommendations. As a
last resort, only when the above
mentioned methods are not available
crank the engine for two minutes
after oil pressure is reached.
Disable the Spark and Fuel while
cranking the engine during this
pre-Lube procedure to prevent
cylinder wall washdown. Check the
oil level and fill to the proper
level.
4. Engine Break-In:
This assembly has been tested and
can be driven without a formal
"break-in" schedule. However after
performing steps 1, 2 and 3, start
the engine and let it idle at 1600
to 2000 RPM for 10 to 20 minutes
allowing the oil pressure and
temperature to stabilize. Refer to
the service manual for the proper
pressure range. During this time,
where applicable, adjust the timing
and valve clearance and check for
leaks. ROAD TEST the vehicle for a
minimum of 10 miles (16.09 km for
Canada) with combined city and
highway driving, do not exceed 50
miles per hour (80 kph for Canada),
or use any fast throttle responses.
Send the vehicle to be cleaned prior
to returning to the customer.
Instruct customer that the first
service interval for changing oil
and filter should be between 300 to
500 miles (500 km to 800 km for
Canada).
For subsequent service, refer to
the manufacturer's recommended
intervals:
For subsequent service, refer to
the manufacturer's recommended
intervals:
