Operating After Break-In - Daewoo DE12T Manual

b) Watch the oil pressure warning lamp. If the lamp blinks, it may be the oil pick-up screen is
not covered with oil. Check oil level gauge. Add oil to the oil pan, if required. Do not overfill.
If level is correct and the status still exists, see your DEALER for possible switch or oil pump
and line malfunction.
Note :
Oil pressure will rise as RPM increases, and fall as RPM decreases. In addition, cold oil
will generally show higher oil pressure for any specific RPM than hot oil. Both of these
conditions reflect normal engine operation.
c) Watch the engine water temperature gauge and be sure there is proper water circulation.
The water temperature gauge needle will fluctuate if water level in expansion tank is too low.
At the end of the break-in period, remove break-in oil and replace the oil filter. Fill oil pan with
recommended engine oil. Refer to following table.

4.2.3. Operating after break-In

When starting a cold engine, always allow the engine to warm up gradually. Never run the
engine at full throttle until the engine is thoroughly warmed up. Be sure to check the oil level
frequently during the first 1,000km(50 hours) of operation, since the oil consumption will be
high until the piston rings are properly seated.
4.2.4. 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.
