1.1. General Repair Instructions
1. Before performing service operation, disconnect the grounding cable from the battery
for reducing the chance of cable damage and burning due to short-circuiting.
2. Use covers for preventing the components from damage or pollution.
3. Engine oil and anti-freeze solution must be handled with reasonable care as they
cause paint damage.
4. The use of proper tools and special tools where specified is important to efficient and
reliable service operation.
5. Use genuine DAEWOO parts necessarily.
6. Used cotter pins, gaskets, O-rings, oil seals, lock washer and self-lock nuts should
be discarded and new ones should be prepared for installation as normal function of
the parts can not be maintained if these parts are reused.
7. To facilitate proper and smooth reassemble operation, keep disassembled parts
neatly in groups. Keeping fixing bolts and nut separate is very important as they vary
in hardness and design depending on position of installation.
8. Clean the parts before inspection or reassembly. Also clean oil ports, etc. using
compressed air to make certain they are free from restrictions.
9. Lubricate rotating and sliding faces of parts with oil or grease before installation.
10. When necessary, use a sealer on gaskets to prevent leakage.
11. Carefully observe all specifications for bolts and nuts torques.
12. When service operation is completed, make a final check to be sure service has
been done property.

1.2. Engine characteristics
1.2.1. OMEGA combustion bowl
The OMEGA combustion bowl is a unit
designed to perform high efficiency, low
emission combustion. As the rim around the
combustion bowl port of the upper of the
piston has been machined in a smaller size
than the interior of the combustion bowl,
strong swirl is produced in the combustion
bowl and strong squish flow makes the fuel be
mixed more sufficiently with air.
Due to the application of OMEGA combustion
system and optimal utilization of intake and
exhaust port configuration within the cylinder
head, the DE12 series diesel engines
discharge very low level of hazardous exhaust
gases such as smoke, nitrogen oxide,
hydrocarbon, or carbon monoxide and thus
ensure high performance and low fuel
consumption.

NOTE:
However, it should not elapse longer than 75 sec, and if it did, the hue would
change.
(4) Make the numerical value by comparing the test paper which hue has
changed with the color list of label on storage bottle.
(5) By comparing the hue changed into yellowish green or so with the green color
indication of test paper storage bottle, confirm the density. (Then, the density
indication must be in the hue range of 33% to 50%).
(6) The brown at the middle of test paper and the lower pink color indication
represent the additive state for rust prevention, and the proper range is that
the meeting numerical value of brown (vertical) and pink color (horizontal)
locates in the range of 0.3 to 0.8 at the color list of label on the test paper
storage bottle.
(7) In case of less than 0.3, replenish the additive for rust prevention (DCA4), and
in case of more than 0.8, pour out the cooling water about 50% and then
readjust the density after refilling with clean fresh water.

2.1.2. Fan belt
Use a fan belt of specified dimensions, and replace if damaged, frayed, or
deteriorated.
Check the fan belt for belt tension.
If belt tension is lower than the specified limit, adjust the tension by relocating the
alternator. (specified deflection: 10 15 mm when pressed down with thumb)

2.1.3. Engine oil
Check oil level with the oil level gauge and replenish if necessary.
Check the oil level with the engine cooled. If the engine is warm, allow time for
5 10 minutes for oil drain into the crankcase before checking oil level. The oil
level must be between Max and Min. lines on the gauge.
Engine oil should be changed at the specified intervals. Oil in the oil filter should
be changed simultaneously.
First oil change After 1,000km (50hr) operation

2.1.7. Intercooler
The intercooler is air to air type and has a large cooling fan capacity. The intercooler
life and performance depends on the intake air condition greatly. Fouled air pollutes
and clogs the air fins of intercooler. As a result of this, the engine output is
decreased and engine malfunction is occurred. So you always check whether the
intake air systems like air filter element are worn or polluted.
2.1.8. Valve clearance adjust procedure
After letting the #1 cylinder's piston come at the compression top dead center by
turning the crankshaft, adjust the valve clearances.
Loosen the lock nuts of rocker arm adjusting screws and push the feeler gauge
of specified value between a rocker arm and a valve stem and adjust the
clearance with adjusting screw respectively and then tighten with the lock nut.
As for the valve clearance, adjust it when in cold, as follow.
