Adding Oil
HGK211
DOHC CVVT V6
The engine oil and filter should be changed at
those intervals specified in the maintenance
schedule in Section 5. If the car is being driven
in severe conditions, more frequent oil and filter
changes are required.
The procedure for changing the oil and filter is
as follows:
1. Park the car on level ground and set the
parking brake. Start the engine and let it
warm up until the needle on the coolant
temperature gauge moves above the lowest
mark. Turn the engine off and place the gear
selector lever in "P" (automatic) or reverse
gear (manual transaxle).4. When the oil has stopped draining, replace
the drain plug using a new washer and
retighten by turning it clockwise.
Tightening torque is:
4.5 ~ 4.0 kgf.m (2.0L)
4.5 ~ 3.5 kgf.m (2.7L)
5. Remove the oil filter by turning it counter-
clockwise with a oil filter wrench of the proper
size. 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. (Tightening torque :

CHECKING AND CHANGING THE
ENGINE COOLANT
!
G050A01A-AAT
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. 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.
NOTE:Always dispose of used engine oil in an
environmentally acceptable manner. It is
suggested that it be placed in a sealed
container and taken to a service station for
reclamation. Do not pour the oil on the
ground or put it in with the household
trash.
PROPOSITION 65 WARNING:Used engine oil may cause irritation or
cancer of the skin if left in contact with the
skin for prolonged periods of time. Used
engine oil contains chemicals that have
caused cancer in laboratory animals. Al-
ways protect your skin by washing your
hands thoroughly with soap and warm
water as soon as possible after handling
used oil.
G050B01A-AAT
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
maintained with the correct concentration and
type of engine coolant to prevent freezing and
corrosion. Never allow the concentration of
antifreeze to exceed the 60% level or go below
the 35% level, or damage to the cooling system
may result. For proper concentration when
adding or replacing the engine coolant, refer to
the following table.

To Check the Coolant Level
G050D02A-AAT
To Change the Engine Coolant
The engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
CAUTION:Engine coolant can damage the finish of
your car. If you spill engine coolant on the
car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park-
ing brake and remove the radiator cap when
cool.
2. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow all
the engine coolant to drain from the cooling
system, then securely close the drain cock.
3. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer’s directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
!
4. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This
relieves any pressure remaining in the cool-
ing system. And remove the radiator cap by
pushing down and turning counterclock-
wise.
Now fill the radiator with clean demineralized
or distilled water. Continue to add clean
demineralized or distilled water in small quan-
tities until the fluid level stays up in the
radiator neck.
G050D03E
The coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool-
ant should be between the "LOW" and "FULL"
lines on the reservoir when the engine is cold.
If the level is below the "LOW" mark, add engine
coolant to bring it up between "LOW" and "FULL".
If the level is low, inspect for coolant leaks and
recheck the fluid level frequently. If the level
drops again, visit your Hyundai dealer for an
inspection and diagnosis of the reason.

5. Start the engine, top off the radiator with
water and then add coolant to the reservoir
until the level is between "LOW" and "FULL".
6. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.
WARNING:The cooling fan is controlled by engine
coolant temperature and may sometimes
operate even when the engine is not run-
ning. Use extreme caution when working
near the blades of the coolant fan so that
you are not injured by a rotating fan blade.
As the engine coolant temperature de-
creases, the fan will automatically shut off.
This is a normal condition.

SPARK PLUGS
G060A01GK-AAT
Your engine was originally equipped with plati-
num-tipped spark plugs. Platinum-tipped spark
plugs will last longer than conventional type
spark plugs and can be identified by blue lines
on the ceramic shell.
NOTE:Do not clean or regap platinum-tipped spark
plugs.

5. To remove the old spark plug, turn the
wrench handle in a counterclockwise direc-
tion.
6. To install the new spark plug, guide the
socket down over the spark plug, being
careful not to damage the ceramic insulator.
NOTE:Spark plugs should be tightened firmly.
Over-tightening can damage the threads in
the aluminum cylinder head. Also, leaving
them too loose can cause the spark plug to
get very hot and possibly result in damage
to the engine.
7. Replace the cable by pushing the insulated
connector directly down onto the electrode.
Check to be sure it has snapped into place
and can't fall off.
