DAEWOO M-150 BL2
CHECKING ENGINE FLUID LEVEL
Check the engine fluid level or condition. If needed, refill
or replace the oil.
Check the engine oil level within engine normal operat-
ing temperature as follows ;
1. After stopping the engine, wait for a few minutes to
accumulate oil into the oil pan.
2. After pulling out the oil level gauge (a), check the oil
level.
3. Clean the oil level gauge and insert the gauge into
guide.
4. After pulling out the oil level gauge again, recheck the
oil level and insert the gauge into guide again.
Important: Oil level should be between “MIN” mark and
“MAX” mark.
5. If oil level is below the “MIN” mark, refill engine oil as
much as the demanded quantify.
Important: If checking oil level under the engine cold
condition, oil is not accumulated into oil pan quickly and
correct level checking can not be performed. Therefore,
wait until temperature reaches the normal operating
condition and check the engine oil level.

CHANGING ENGINE OIL OR OIL
FILTER
Tools Required
09915–47341 Oil Filter Wrench.
When checking engine oil level or condition, if needed,
change engine oil (including the filter) as follows ;
1. After stopping the engine, wait for a few minutes to
accumulate oil into the oil pan.
2. Remove the oil filter cap (b).3. Remove the oil drain plug (c) and draw oil off.
D102A302
4. After drawing oil completely, tighten the oil drain plug
to 30–40 Nm (22–30 lb-ft).
5. Replace the oil filter using the oil filter wrench
09915–47341 (d).

Remove the air cleaner/resonator/snorkel as-
sembly.

After removing the bolts, remove the heat
shield.

Loosen the power steering pump cap screw and
pull the power steering hose into the front.

Remove the oil filter.
Important: Whenever changing engine oil, replace the
oil filter. When replacing new oil filter, apply engine oil on
oil filter sealing.
