CHANGING THE OIL AND FILTER (DIESEL ENGINE)
The engine oil and filter should be changed at
those intervals specified in the maintenance schedule 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 it warm 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. 3. Slide underneath the car and loosen the oil
pan drain plug by turning it counterclockwiseoil pan with a wrench of the proper size. Besure that a drain pan is in position to catch theoil 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. Oil pan drain plug tightening torque: 3.5 ~ 4.5 kgf.m
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 : 1.2~1.6 kgf.mBe 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.
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 sug- gested that it be placed in a sealed containerand taken to a service station for maybereclaimation. Do not pour the oil on theground or put it in with 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 yourhands thoroughly with soap and warm wa-ter as soon as possible after handling usedoil. 5. Loosen the oil filter drain plug by turning it
counterclockwise with a wrench of the propersize and drain out some oil in the oil filter. Be surethat a drain pan is in position to catch the oil.

8. Install a new copper washer of the oil filter drain plug by the side of lower case andretighten by turning it clockwise.
Tightening torque : 0.8 ~ 1.0 kgf.m
9. After mounting a new oil filter element and new O-ring to upper cap, install the upper cap to lower case and retighten by turning itclockwise. Do not over-tighten.
Tightening torque : 2.3 ~ 2.5 kgf.m
10. Refill the crankcase with the recommended engine oil. Refer to the specification in chap- ter 9 for engine oil capacity.
11. Start the engine and check to be sure no oil is leaking from the drain plug or oil filter.
12. Shut off the engine and recheck the oil level.
NOTE: It is recommended that the engine oil and
filter should be changed by an authorized Hyundai dealer. G050A01A-AAT
CHECKING AND CHANGING THE ENGINE 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 mayerupt through the opening if the cap isremoved. You could be seriously burned ifyou do not observe this precaution. Do notremove the radiator cap until the radiator iscool to the touch. NOTE: Always dispose of used engine oil in an environmentally acceptable manner. It is sug-gested that it be placed in a sealed containerand taken to a service station for maybereclaimation. Do not pour the oil on theground or put it into the household trash. WARNING: Used motor oil may cause irritation or
cancer
of the skin if left in contact with the skin for prolonged periods of time. Wash your handsthoroughly with soap and warm water assoon as possible after handling used oil.

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 bypushing down and turning counterclockwise. Now fill the radiator with clean demineralized or distilled water. Continue to add clean deminer-alized or distilled water in small quantities untilthe fluid level stays up in the radiator neck.

REPLACING THE SPARK PLUGS The spark plugs should be changed at theintervals specified in the vehicle maintenancesschedule 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:
SSA6060A
Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm (0.028 ~ 0.032 in.)

5. Start the engine, top off the radiator with
water and then add engine 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 fullyclosed 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 cooling 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.

NOTE: Spark plugs should be tightened firmly. Over- tightening can damage the threads in thealuminum cylinder head. Leaving them tooloose can cause the spark plugs to get veryhot and possibly result in damage to theengine.
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.
SSA6061ASSA6062A
WARNING: It is recommended that the engine be cool
or cold when changing the spark plugs. If the engine is hot, you could burn yourself on the insulated connector, the spark plug or 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 spark plug, turn the wrench handle in a counterclockwise direction.
6. To install the new spark plug, guide the socket down over the spark plug, beingcareful not to damage the ceramic insulator.
G060C01S-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 center cover on the engine rocker cover.
2. Using a clean cloth, remove any dirt that has accumulated around the spark plug so it cannot fall into the cylinder when the sparkplug 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.
