GENERAL DESCRIPTION
AND SYSTEM OPERATION
GENERAL REPAIR INSTRUCTIONS
lIf a floor jack is used, the following precautions are
recommended.
lPark the vehicle on level ground, “block” the front or
rear wheels, set the jack against the frame, raise the
vehicle and support it with chassis stands and then
perform the service operation.
lBefore performing the service operation, disconnect
the negative battery cable in order to reduce the
chance of cable damaged and burning due to short-
cir cuiting.
lUse a cover on the body, the seats and the floor to
protect them against damage and contamination.
lHandle brake fluid and antifreeze solution with care
as they can cause paint damage.
lThe use of proper tools, and the recommended
essential and available tools where specified, are
important for efficient and reliable performance of
the service repairs.lUse genuine DAEWOO parts.
lDiscard used cotter pins, gaskets, O-rings, oil seals,
lock washers and self-locking nuts. Prepare new ones
for installation. Normal function of these parts cannot
be maintained if these parts are reused.
lKeep the disassembled parts neatly in groups to
facilitate proper and smooth reassembly.
lKeep attaching bolts and nuts separated, as they
vary in hardness and design depending on the
position of the installation.
lClean the parts before inspection or reassembly.
lAlso clean the oil parts, etc. Use compressed air to
make certain they are free of restrictions.
lLubricate rotating and sliding faces of parts with oil
or grease before installation.
lWhen necessary, use a sealer on gaskets to prevent
leakage.
lCarefully observe all specifications for bolt and nut
torques.
lWhen service operation is completed, make a final
check to be sure service was done properly and the
problem was corrected.

VEHICLE LIFTING PROCEDURES
To raise the vehicle, place the lifting equipment only at
the points indicated. Failure to use these precise
positions may result in permanent vehicle body
deformation.
Many dealer service facilities and service stations are
equipped with automative hoists that bear upon some
parts of the frame in order to lift the vehicle. If any other
hoist method is used, take special care to avoid
damaging the fuel tank, the filter neck, the exhaust
system, or the underbody.

GENERAL INFORMATION
CLEANLINESS AND CARE
An automobile engine is a combination of many
machined, honed, polished and lapped surfaces with
tolerances that are measured in the ten-thousanths of
an inch. When any internal engine parts are serviced,
care and cleanliness are important. A liberal coating of
enigne oil should be applied to friction areas during
assembly, to protect and lubricate the surfaces on initial
operation. Proper cleaning and protection of machined
surfaces and friction areas is part of the repair
procedure. This is considered standard shop practice
even if not specifically stated.
Whenever valve train components are removed for
service, they should be kept in order. They should be
installed in the same locations, and with the same mating
surfaces, as when they were removed.Battery cables should be disconnected before any major
work is performed on the engine. Failure to disconnect
cables may result in damage to wire harness or other
electrical parts.
ON-ENGINE SERVICE
Caution: Disconnect the negative battery cable
before removing or installing any electrical unit, or
when a tool or equipment could easily come in
contact with exposed electrical terminals.
Disconnecting this cable will help prevent personal
injury and damage to the vehicle. The ignition must
also be in LOCK unless otherwise noted.
Notice: Any time the air cleaner is removed, the intake
opening should be covered. This will protect against
accidental entrance of foreign material, which could
follow the intake passage into the cylinder and cause
extensive damage when the engine is started.
