MAINTENANCE AND REPAIR
MAINTENANCE AND LUBRICATION
NORMAL VEHICLE USE
The maintenance instructions contained in the mainte-
nance schedule are based on the assumption that the ve-
hicle will be used for the following reasons:
S To carry passengers and cargo within the limitation
indicated on the tire placard located on the edge of
the driver’s door.
S To be driven on reasonable road surfaces and with-
in legal operating limits.
EXPLANATION OF SCHEDULED
MAINTENANCE SERVICES
The services listed in the maintenance schedule are fur-
ther explained below. When the following maintenance
services are performed, make sure all the parts are re-
placed and all the necessary repairs are done before driv-
ing the vehicle. Always use the proper fluid and lubricants.
Drive Belt Inspection
When a separate belt drives the power steering pump, the
air conditioning compressor and the generator, inspect it
for cracks, fraying, wear and proper tension. Adjust or re-
place the belt as needed.
Engine Oil and Oil Filter Change
API Classifications of Engine Oil
The International Lubricant Standardization and Approval
Committee (ILSAC) and American Petroleum Institute
classifies engine oils according to their performance quali-
ty. Always use oil rated API–SL (ILSAC GF–III) or better.
Engine Oil Viscosity
Engine oil viscosity (thickness) has an effect on fuel econ-
omy and cold weather operation. Lower viscosity engine
oils can provide better fuel economy and cold weather per-
formance; however, higher temperature weather condi-
tions require higher viscosity engine oils for satisfactory lu-
brication. Using oils of any viscosity other than those
viscosities recommended could result in engine damage.
Cooling System Service
Drain, flush and refill the system with new coolant. Refer
to ”Recommended Fluids And Lubricants” in this section.
Fuel Micro–Filter Replacement
Replace the engine fuel filter every 45,000 km (27,000
miles).
Air Cleaner Element Replacement
Replace the air cleaner element every 45,000 km (27,000
miles).Replace the air cleaner more often under dusty conditions.
Throttle Body Mounting Bolt Torque
Check the torque of the mounting bolts.
Tighten the throttle body mounting bolts to 15 NSm (11 lb–
ft) if necessary.
Spark Plug Replacement
Replace spark plugs with the same type.
Spark Plug Wire Replacement
Clean wires and inspect them for burns, cracks or other
damage. Check the wire boot fit at the DIS module and at
the spark plugs. Replace the wires as needed.
Brake System Service
Check the disc brake pads and the drum brake linings ev-
ery 15,000 km (9,000 miles) or 12 months. Check the pad
and the lining thickness carefully. If the pads or the linings
are not expected to last to the next scheduledmaintenance
service, replace the pads or the linings. Check the breath-
er hole in the brake fluid reservoir cap to be sure it is free
from dirt and the passage is open.
Transaxle Service
The manual transaxle fluid does not require changing. For
automatic transaxles, refer to ”Scheduled Maintenance
Charts” in this section.
Tire and Wheel Inspection and Rotation
Check the tires for abnormal wear or damage. To equalize
wear and obtain maximum tire life, rotate the tires. If irreg-
ular or premature wear exists, check the wheel alignment
and check for damaged wheels. While the tires and
wheels are removed, inspect the brakes. Refer to ”Each
Time The Oil Is Changed” in this section.

R – Replace or change:
(1) Refer to Recommended Fluids And Lubricants.
(2) And if necessary, rotate and balance wheels.
(3) More frequent if operated under severe conditions: short distance driving, extensive idling, frequent low–speed oper-
aion in stop and go traffic, or driving in dusty conditions.
(4) Change the brake/clutch fluid every 15,000 km (9,000 miles), if the vehicle is mainly driven under the following severe
conditions: driving in hilly or mountainous terrain, or towing a trailer/caravan frequently.
(5) 1.8 DOHC model (ZF 4HP16 Automatic Transaxle): Change automatic transaxle fluid every 60,000 Km (36,000 miles)
if the vehicle is mainly driven under any of the following severe conditions:
S In heavy city traffic where the outside temperature regularly reaches 32°C (90°F) or higher, or
S In hilly or mountainous terrain, or
S When doing frequent trailer towing, or
S Uses such as taxi, police or delivery service.

GENERAL INFORMATION 0B – 13
DAEWOO V–121 BL4
EACH TIME THE OIL IS CHANGED
Automatic Transaxle Fluid
Refer to fluid level service procedure of Section 5A, ZF
4HP16 Automatic Transaxle.
Manual Transaxle
Check the fluid level and add fluid as required. Refer to
Section 5B, Five–Speed Manual Transaxle.
Brake System Inspection
This inspection should be done when the wheels are re-
moved for rotation. Inspect the lines and the hoses for
proper hookup, binding, leaks, cracks, chafing, etc. In-
spect the disc brake pads for wear. Inspect the rotors for
surface condition. Also inspect the drum brake linings for
wear and cracks. Inspect other brake parts, including the
drums, the wheels cylinders, the parking brake, etc., at the
same time. Check the parking brake adjustment. Inspect
the brakes more often if habit or conditions result in fre-
quent braking.
Steering, Suspension and Front Drive Axle
Boot And Seal Inspection
Inspect the front and rear suspension and the steering
system for damaged, loose or missing parts, signs of wear
or lack of lubrication. Inspect the power steering lines and
the hoses for proper hookup, binding, leaks, cracks, chaf-
ing, etc. Clean and inspect the drive axle boot and seals
for damage, tears or leakage. Replace the seals if neces-
sary.
Exhaust System Inspection
Inspect the complete system (including the catalytic con-
verter if equipped). Inspect the body near the exhaust sys-
tem. Look for broken, damaged, missing, or out–of–posi-
tion parts as well as open seams, holes, loose
connections, or other conditions which could cause heat
buildup in the floor pan or could let exhaust fumes seep
into the trunk or passenger compartment.
Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
damaged, or missing parts. Lubricate all linkage joints and
throttle cable joints, the intermediate throttle shaft bearing,
the return spring at throttle valve assembly, and the accel-
erator pedal sliding face with suitable grease. Check the
throttle cable for free movements.
Engine Drive Belts
Inspect all belts for cracks, fraying, wear and proper ten-
sion. Adjust or replace the belts as needed.
Hood Latch Operation
When opening the hood, note the operation of the secon-
dary latch. It should keep the hood from opening all the
way when the primary latch is released. The hood must
close firmly.
AT LEAST ANNUALLY
Lap and Shoulder Belts Condition and
Operation
Inspect the belt system including: the webbing, the
buckles, the latch plates, the retractor, the guide loops and
the anchors.
Movable Head Restraint Operation
On vehicles with movable head restraints, the restraints
must stay in the desired position.
Spare Tire and Jack Storage
Be alert to rattles in the rear of the vehicle. The spare tire,
all the jacking equipment, and the tools must be securely
stowed at all times. Oil the jack ratchet or the screw mech-
anism after each use.
Key Lock Service
Lubricate the key lock cylinder.
Body Lubrication Service
Lubricate all the body door hinges including the hood, the
fuel door, the rear compartment hinges and the latches,
the glove box and the console doors, and any folding seat
hardware.
Transaxle Neutral Switch Operation on
Automatic Transaxle
CAUTION : Take the following precautions because
the vehicle could move without warning and possibly
cause personal injury or property damage:
S Firmly apply the parking brake and the regular
brakes.
S Do not use the accelerator pedal.
S Be ready to promptly turn off the ignition if the ve-
hicle starts.
On automatic transaxle vehicles, try to start the engine in
each gear. The starter should crank only in P (Park) or N
(Neutral).
Parking Brake and Transaxle P (Park)
Mechanism Operation
CAUTION : In order to reduce the risk of personal in-
jury or property damage, be prepared to apply the reg-
ular brakes promptly if the vehicle begins to move.
Park on a fairly steep hill with enough room for movement
in the downhill direction. To check the parking brake, with
the engine running and the transaxle in N (Neutral), slowly
remove foot pressure from the regular brake pedal (until
only the parking brake is holding the vehicle).
To check the automatic transaxle P (Park) mechanism’s
holding ability, release all brakes after shifting the trans-
axle to P (Park).
Underbody Flushing
Flushing the underbody will remove any corrosive materi-
als used for ice and snow removal and dust control. At
least every spring clean the underbody. First, loosen the
sediment packed in closed areas of the vehicle. Then flush
the underbody with plain water.
