Checking And Changing The Engine Coolant - Hyundai 2001 Sonata Owner's Manual

3. Slide underneath the car and loosen the
drain plug by turning it counterclockwise
with a wrench of the proper size. Be sure
that a drain pan is in position to catch the oil
as it drains out, then remove the drain plug.
WARNING:
Be very careful when draining the engine oil
as it may be hot enough to burn you!
4. When the oil has stopped draining, replace
the drain plug using a new washer and
retighten by turning it clockwise.
5. Remove the oil filter. You should be able to
unscrew the filter with your hands. (If your
hands are slippery, try to use a cloth be-
tween your hands and the filter to give
yourself a better grip.) A certain amount of
oil will come out when you remove the filter,
so be sure to have your drain pan in place
underneath it.
6. Install a new oil filter in accordance with the
instructions on the carton or on the filter
itself. Do not over-tighten. Be sure that the
mounting surface on the engine is clean and
that the old gasket is removed completely.
Lubricate the new gasket on the filter with
clean engine oil before installation.
7. Refill the crankcase with the recommended
engine oil. Refer to the specification in chap-
ter 9 for engine oil capacity.
8. Start the engine and check to be sure no oil
is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level.
DO-IT-YOURSELF MAINTENANCE
NOTE:
Always dispose of used engine oil in an
environmentally acceptable manner. It is sug-
gested that it be placed in a sealed container
and taken to a service station for reclama-
tion. Do not pour the oil on the ground or
put it into the household trash.
WARNING:
Used motor oil may cause irritation or can-
cer of the skin if left in contact with the skin
for prolonged periods of time. Wash your
hands thoroughly with soap and warm wa-
ter as soon as possible after handling used
oil.

CHECKING AND CHANGING THE EN-
GINE COOLANT
WARNING:
Do not remove the radiator cap when the
engine is hot. When the engine is hot, the
engine coolant is under pressure and may
erupt through the opening if the cap is
removed. You could be seriously burned if
you do not observe this precaution. Do not
remove the radiator cap until the radiator is
cool to the touch.

Recommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should
be compatible with aluminum engine parts.
Additional corrosion inhibitors or additives should
not be used. The cooling system must be main-
tained with the correct concentration and type
of engine coolant to prevent freezing and corro-
sion. Never allow the concentration of anti-
freeze to exceed the 60% level or go below the
35% level, or damage to the cooling system
may result. For proper concentration when add-
ing or replacing the engine coolant, refer to the
following table.
