Engine Cooling System
Inspect the coolant and freeze protection fluid. If the fluid
is dirty or rusty, drain, flush and refill the engine cooling
system with new coolant. Keep the coolant at the proper
mixture in order to ensure proper freeze protection, corro-sion protection and engine operating temperature. Inspect
the hoses. Replace the cracked, swollen, or deteriorated
hoses. Tighten the clamps. Clean the outside of the radia-
tor and the air conditioning condenser. Wash the filler cap
and the neck. Pressure test the cooling system and the
cap in order to help ensure proper operation.

GENERAL DESCRIPTION
AND SYSTEM OPERATION
GENERAL REPAIR INSTRUCTIONS
S If a floor jack is used, the following precautions are
recommended.
S Park 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.
S Before performing the service operation, disconnect
the negative battery cable in order to reduce the
chance of cable damage and burning due to short–
circuiting.
S Use a cover on the body, the seats and the floor to
protect them against damage and contamination.
S Handle brake fluid and antifreeze solution with care
as they can cause paint damage.
S The use of proper tools, and the recommended es-
sential and available tools where specified, are im-
portant for efficient and reliable performance of the
service repairs.S Use genuine DAEWOO parts.
S Discard 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 re-
used.
S Keep the disassembled parts neatly in groups to
facilitate proper and smooth reassembly.
S Keep attaching bolts and nuts separated, as they
vary in hardness and design depending on the posi-
tion of the installation.
S Clean the parts before inspection or reassembly.
S Also clean the oil parts, etc. Use compressed air to
make certain they are free of restrictions.
S Lubricate rotating and sliding faces of parts with oil
or grease before installation.
S When necessary, use a sealer on gaskets to pre-
vent leakage.
S Carefully observe all specifications for bolt and nut
torques.
S When service operation is completed, make a final
check to be sure service was done properly and the
problem was corrected.

VEHICLE LIFTING PROCEDURES
Notice : 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 deforma-
tion. Many dealer service facilities and service stations areequipped with automotive hoists that bear upon some
parts of the frame in order to lift the vehicle. If any other
hoist method is used, use special care to avoid damaging
the fuel tank, the filler neck, the exhaust system, or the un-
derbody.
