To Check the Oil Level G030D01A-GAT
Adding Oil
Before checking the oil, warm up the engine to
the normal operating temperature and be sure it is parked on level ground. Turn the engine off.
Wait five minutes, then remove the dipstick,
wipe it off, fully reinsert the dipstick and with-draw it again. Then note the highest level the oilhas reached on the dipstick. It should be be-tween the upper ("FULL") and lower ("LOW")range. If the oil level is close to or below the "L" mark,
add oil until it reaches the "F" mark. To add oil:
1. Remove the oil filler cap by turning it counter- clockwise.
2. Add oil, then check the level again. Do not overfill.
3. Replace the cap by turning it clockwise.
The distance between the "F" and "L" marks is
equal to about 1 liter of oil.HGK211
DOHC V6 DOHC V6
See the lubrication chart on the page 9-3. NOTE:
o The use of a 5W-20 multi grade oil is not recommended for sustained high speed use.
o When replacing or adding the oil, below SAE 10W-30 is recommended. Using a high viscosity oil of SAE 15W-40 and over makes malfunction of CVVTengine when the engine is cool.

CHANGING THE OIL AND FILTER
The engine oil and filter should be changed at those intervals specified in the maintenanceschedule in Section 5. If the car is being drivenin severe conditions, more frequent oil and filterchanges 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 itwarm up until the needle on the coolanttemperature gauge moves above the lowestmark. Turn the engine off and place the gearselector lever in "P" (automatic) or reversegear (manual transaxle).
2. Open the hood and remove the engine oil filler cap.
G040A01GK 3. Slide underneath the car and loosen the
drain plug by turning it counterclockwise with a wrench of the proper size. Be surethat a drain pan is in position to catch the oilas 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. Tightening torque :
4.5 ~ 4.0 kgf.m (1.6/2.0L) 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 willcome out when you remove the filter. So besure to have your drain pan in place under-neath it.
6. Install a new oil filter in accordance with the instructions on the carton or on the filteritself. Do not over-tighten. Tightening torque: 1.2 ~ 1.6 kgf.m.Be sure that the mounting surface on the engine is clean and that the old gasket isremoved completely. Lubricate the new gas-ket on the filter with clean engine oil beforeinstallation.

ENGINE OIL CONSUMPTION Function of Engine Oil
Engine oil has the primary function of lubricat-
ing and cooling the inside of the engine.
Engine oil consumption It is normal that an engine should consume
some engine oil while normal driving. The cause of oil consumption in a normal engine are asfollows;
o Engine oil is used to lubricate pistons, piston rings and cylinders.
o A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. High negative pressure generatedduring engine operation sucks some of theoil into the combustion chamber. This oil with some oil of the cylinder wall is burned by the high temperature combustiongases during the combustion process.
o The engine oil consumption is strongly ef- fected by the viscosity and quality of oil,engine rpm and driving condition etc. Moreengine oil may be consumed under severedriving conditions such as high speeds, fre-quent acceleration and deceleration, com-pared to normal driving condition. V6

check to be sure the drain cocks are fully closed and not leaking.
WARNING: The cooling fan is controlled by engine cool- ant temperature and may sometimes oper-ate even when the engine is not running.Use extreme caution when working near theblades of the coolant fan so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition. G060A02Y-GAT
SPARK PLUGS
YN60100A
V6
Your engine was originally equipped with plati- num-tipped spark plugs. (For 2.7L only). Platinum-tipped spark plugs will last longer than conventional type spark plugs and can be iden-tified by blue lines on the ceramic shell. NOTE: Do not clean or regap platinum-tipped spark plugs.
G060B01GK-GAT
Replacing the Spark Plugs The spark plugs should be changed at the
intervals specified in the vehicle maintenanceschedule in Section 5 or whenever engine per-formance indicates they should be changed.Symptoms that suggest poor spark plug perfor-mance include engine misfiring under load, lossof fuel economy, poor acceleration, etc. Whenspark plugs are replaced, always use sparkplugs recommended by Hyundai. The use ofother spark plugs can result in loss of perfor-mance, radio interference or engine damage.
NOTE: When replacing the spark plugs, genuine
Hyundai replacement parts are recom- mended. Recommended Spark Plugs:

To Change the Engine Coolant
The engine coolant should be changed at those
intervals specified in the vehicle maintenance schedule in Section 5.
NOTE: 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. Allowall the engine coolant to drain from thecooling system, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car. Then, followingthe manufacturer's directions on the enginecoolant container, add the appropriate quan-tity of engine coolant to the radiator.
4. Turn the radiator cap counterclockwise with- out pressing down on it, until it stops. Thisrelieves any pressure remaining in the cool-ing system. And remove the radiator cap bypushing down and turning counterclockwise. Now fill the radiator with clean demineral- ized or distilled water. Continue to add cleandemineralized or distilled water in small quan-tities until the fluid level stays up in theradiator neck. DOHC1.0~1.1 mm (0.039 ~ 0.043 in.)

WARNING: It is recommended that the engine be cool
or cold when changing the spark plugs. If the engine is hot, you could burn yourselfon the insulated connector, the spark plugor the engine itself.
4. When preparing to remove the old spark plug, guide the socket down over the spark plug, being careful not to damage the ce-ramic insulator.
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, beingcareful not to damage the ceramic insulator. NOTE: Spark plugs should be tightened firmly. Over- tightening can damage the threads in thealuminum cylinder head. Also, leaving them too loose can cause the spark plug to get very hot and possibly result in damage tothe engine.
7. Replace the cable by pushing the insulated connector directly down onto the electrode.Check to be sure it has snapped into placeand can't fall off.
G060C02GK-GAT
Changing the Spark Plugs
You will find it easier to change spark plugs if
the engine is cold. Always change one sparkplug at a time. This helps avoid getting the wiresmixed up.
1. Remove the engine rocker cover.
NOTE: It is recommended that the spark plugs for
2.7L Engines should be changed by an au- thorized Hyundai dealer.
2. Using a clean cloth, remove any dirt that has accumulated around the base of the spark plug so it cannot fall into the cylinder whenthe spark plug is removed.
3. To remove the spark plug cable, pull straight up on the insulated connector, not the cable.Pulling on the cable may damage the carboncore conductor.
