CHANGING THE OIL AND FILTER
G350A01A-GAT ENGINE OIL CONSUMPTION Function of Engine Oil Engine oil has the primary function of lubricating and cooling the inside of theengine. Engine oil consumption It is normal that an engine should consume some engine oil while nor-mal driving. The cause of oil consump- tion in a normal engine are as follows;
o Engine oil is used to lubricate pis-
tons, piston rings and cylinders. A thin film of oil is left on the cylinderwall when a piston moves down- wards in the cylinder. High negative pressure generated during engineoperation sucks some of the oil into the combustion chamber. This oil with some oil of the cylinderwall is burned by the high tempera-
ture combustion gases during the combustion process.
o The engine oil consumption is strongly effected by the viscosityand quality of oil, engine rpm anddriving condition etc. The engine oil is more consumed under severe driving conditions such as highspeeds and frequent acceleration and deceleration than normal driv- ing condition.

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 counterclockwise.
2. Add oil, then check the level again.
Do not overfill.
3. Replace the cap by turning it clock- wise.
The distance between the "F" and "L" marks is equal to about 1 liter(Gasoline Engine)/1.2 liter(Diesel Engine) of oil.
WARNING:
Be very careful not to touch the radia-tor hose when checking the engine oil as it may be hot enough to burn you.

The engine oil and filter should be changed at those intervals specified inthe maintenance schedule in Section 5. If the car is being driven in 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 coolant temperature gauge movesabove the lowest mark. Turn the engine off and place the gear selec- tor lever in "P" (automatic) or reversegear (manual transaxle).
2. Open the hood and remove the en-
gine oil filler cap.
3. Slide underneath the car and loosen the drain plug by turning it counter-clockwise with a wrench of the propersize. 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.
Tightening torque : 3.5 ~ 4.5 kgf.m
5. Remove the oil filter by turning it counterclockwise with a oil filter wrench of the proper size. A certainamount of oil will come out when you remove the filter. So be sure to have your drain pan in place underneathit.
6. Install a new oil filter in accordance
with the instructions on the carton oron the filter itself. Do not over-tighten.

CHECKING AND CHANGING THE ENGINE COOLANT
G050A01A-AAT G050B01A-AAT Recommended Engine Coolant Use a high quality ethylene-glycol cool- ant in a 50/50 mix with water. Theengine coolant should be compatible with aluminum engine parts. Additional corrosion inhibitors or additives shouldnot be used. The cooling system must be maintained with the correct con- centration and type of engine coolantto prevent freezing and corrosion. Never allow the concentration of anti- freeze to exceed the 60% level or gobelow the 35% level, or damage to the cooling system may result. For proper concentration when adding or replacingthe engine coolant, refer to the following table.
WARNING:
Do not remove the radiator cap when the engine is hot. When the engine ishot, the engine coolant is under pres- sure and may erupt through the open- ing if the cap is removed. You couldbe seriously burned if you do not observe this precaution. Do not re- move the radiator cap until the radia-tor is cool to the touch.

G050C01A-GAT To Check the Coolant Level The coolant level can be seen on the side of the plastic coolant reservoir. The level of the coolant should be between the "L" and "F" lines on thereservoir when the engine is cold. If the level is below the "L" mark, add engine coolant to bring it up between "L" and"F". 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 inspec- tion and diagnosis of the reason.

G050D02A-AAT To Change the Coolant The coolant should be changed at those intervals specified in the vehiclemaintenance schedule in Section 5.
CAUTION:
Engine coolant can damage the fin-ish of your car. If you spill engine coolant on the car, wash it off thor- oughly with clean water.
!
1. Park the car on level ground, set the parking brake and remove the ra- diator cap when cool.
2. Be sure your drain receptacle is in place. Open the drain cock on theradiator. Allow all the engine coolantto 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 direc- tions on the engine coolant contain-er, add the appropriate quantity of coolant to the radiator. 4. Turn the radiator cap counterclock-
wise without pressing down on it, until it stops. This relieves any pres- sure remaining in the cooling sys- tem. And remove the radiator capby pushing down and turning coun- terclockwise. Now fill the radiator with clean dem-ineralized or distilled water. Con- tinue to add clean demineralized or distilled water in small quantitiesuntil the fluid level stays up in the radiator neck. G050D02A
5. Start the engine, top off the radiator with water and then add engine coolant to the reservoir until thelevel is between "L" and "F".
6. Replace the radiator and reservoir
caps and check to be sure the draincocks are fully closed and not leak- ing.

REPLACING THE SPARK PLUGS
WARNING:
The cooling fan is controlled by engine coolant temperature andmay sometimes operate even when the engine is not running. Use ex- treme caution when working nearthe blades of the cooling fan so that you are not injured by a rotating fan blade. As the engine coolant tem-perature decreases, the fan will auto- matically shut off. This is a normal condition.

The spark plugs should be changed at the intervals specified in the vehicle maintenances schedule in Section 5 or whenever engine performance indicatesthey should be changed. Symptoms that suggest poor spark plug perfor- mance include engine misfiring underload, loss of fuel economy, poor accel- eration, etc. When spark plugs are re- placed, always use spark plugs recom-mended by Hyundai. The use of other spark plugs can result in loss of perfor- mance, radio interference or enginedamage. NOTE: When replacing the spark plugs, genuine Hyundai replacement parts are recommended. Recommended Spark Plugs:
Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm(0.028 ~ 0.032 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 yourself on the in- sulated connector, the spark plug or the engine itself. G060C03A
6. To install the new spark plug, guide
the socket down over the sparkplug, being careful not to damage the ceramic insulator.
NOTE: Spark plugs should be tightened firmly. Over-tightening can damagethe threads in the aluminum cylin- der head. Also, leaving them too loose can cause the spark plug toget 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'tfall off.
HLC5023
G060C01S-GAT Changing the Spark Plugs You will find it easier to change spark plugs if the engine is cold. Alwayschange one spark plug at a time. This helps avoid getting the wires mixed up.
1. Remove the center cover on the en-
gine rocker cover (DOHC engine only.)
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 when the spark plug is removed.
3. To remove the spark plug cable, pull straight up on the insulated connec-tor, not the cable. Pulling on thecable may damage the carbon core conductor. G060C01A
4. When preparing to remove the oldspark plug, guide the socket downover the spark plug, being careful not to damage the ceramic insula-tor.
5. To remove the old spark plug, turn
the wrench handle in a counter-clockwise direction.
