ENGINE OIL REPLENISHMENT
If the indicated oil level is at or below the lower mark of the dipstick, oilshould be added until the level is at or below the upper mark. To add oil to the engine, remove the filler cap by rotating in an counter- clockwise direction and pour engine oil into the engine. Before checkingthe level again, allow several minutes for the oil to drain into the sump. Replace the oil filler cap rotating it ina clockwise direction until tight.The quantity of oil required to raisethe level from the minimum to maxi- mum level is approximately 1 litre. 1.6L/2.0L
G350A01A-GAT ENGINE OIL CONSUMPTION Function of engine oil Engine oil has the primary function of lubricating and cooling the inside of the engine. Engine oil consumption It is normal that an engine should consume some engine oil while nor- mal driving. The cause of oil con- sumption in a normal engine are asfollows;
o Engine oil is used to lubricate pis-
tons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. High negative pressure generated dur-ing engine operation sucks some of the oil into the combustion cham- ber.This oil with some oil of the cylin-der wall is burned by the high tem-perature combustion gases during the combustion process.
2.7L
!WARNING:
Be very careful not to touch the
radiator hose when checking the engine oil as it may be hot enough to burn you.

3. Prepare a suitable receptacle to
collect the displaced oil and re- move the drain plug from the sump.
WARNING:
The oil being drained from the
engine will be hot. Care should beexercised to prevent scalding. 6. Install a new oil filter having
smeared the sealing ring with cleanoil and rotating clockwise until the filter contacts the mounting and then a further one half turn. Do notover-tighten. Tightening torque: 1.2 ~ 1.6 kgf.m
7. Remove the engine oil level dip- stick.
8. Pour the specified quantity of the recom-mended oil into the engine and replace the filler cap. Start theengine and ensure that no oil leaks exist. Turn off the engine and after a couple minutes, recheck the oillevel.
4. When the oil has drained from the
sump, replace the drain plug usinga new gasket ensuring that the plug is not over tightened. 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 rotating counterclock-wise, using a propri-etary oil filter removal tool if neces- sary. Note that the oil filter will contain approximately 0.5 litres ofoil and this should be collected in a suitable receptacle. WARNING:
Prolonged and repeated contact with used engine oils may result inserious skin disorders including dermatitis and cancer. Avoid con- tact with skin as far as possibleand always wash thoroughly after any contact. Keep used oils out of reach of children. It is illegal topollute drains, water courses and soil. Use only authorized waste collection facilities including civic amenity sites and garages for the disposal of used oil and oil filters.If in doubt, contact the local au- thority for disposal instructions.

Coolant recommendations
Only ethylene glycol based coolant with a corrosion inhibitor suited to aluminium alloy engine components should be used in the cooling system.No further additives or inhibitors should be used. The coolant specific gravity should be checked as pre-scribed in the maintenance schedule to ensure adequate frost and corro- sion protection. In addition, the en-gine coolant must be replaced at the specified interval since the corrosion inhibitor properties deteriorate withtime.It is important to note that whilst anincrease in the concentration of anti freeze gives an increase in the level of frost protection, a solution which isin excess of 65% anti freeze will result in reduced frost protection and engine overheating. Therefore therecommended concentration of 50% should not be exceeded for general use. The use of methanol based anti freeze compounds may result in engine over- heating and will invalidate the vehiclewarranty.

ENGINE COOLANT CHECK- ING AND REPLACING
SG050A1-E
WARNING:
Do not remove the radiator cap
when the engine is hot, since the system is pressurized and coolant may be ejected from the radiator resulting in scalding. NOTE: It is imperative that vehicles fitted
with an air conditioning system have a coolant concentration of the recommended strength at all times. The use of the air condition-ing system when the cooling sys- tem is filled with water only will result in the heater matrix freezingand subsequently bursting.

SPARK PLUGS
G060A01GK-EAT Your engine was originally equipped with platinum-tipped or iridium-tipped spark plugs (2.7L only).Platinum-tipped or iridium-tipped sparkplugs will last longer than conven-tional type spark plugs. Platinum- tipped spark plug can be identified by blue lines on the ceramic shell. NOTE: Do not clean or regap platinum- tipped/iridium-tipped spark plugs.
0.039 ~ 0.043 in. (1.0~1.1 mm)
!WARNING:
The cooling fan is controlled by engine coolant temperature and may sometimes operate even whenthe engine is not running. Use extreme caution when working near the blades of the cooling fan sothat you are not injured by a rotat- ing fan blade. As the engine cool- ant temperature decreases, the fanwill automatically shut off. This is a normal condition.
5. Prepare a suitable quantity of new
engine coolant (refer to section 9) and pour this into the radiator.

6. Start the engine with the radiator
cap still removed and continue to add coolant as the level decreases as air is expelled from the system.When the level remains constant, replace the radiator cap and re- plenish the coolant reservoir.
7. When the engine is hot, check to ensure that no coolant leaks arepresent.

NOTE: Spark plugs should be tightened firmly. Over-tightening can dam-age the threads in the aluminum cylinder head. Also, leaving them too loose can cause the spark plugto 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.

Whilst the engine is idling, apply the
brakes and move the gear selectorlevel from "P" to each of its other positions — "R", "N", "D" — and then return to "N" or "P". With the enginestill idling:
Recommended Lubricant Use only Hyundai Genuine ATF SP- III, DIAMOND ATF SP-III, SK ATF SP-III or other brands approved byHyundai Motor Co., Damage caused by a nonspecified fluid is not covered by your new vehicle limited warranty. Transaxle Fluid Capacity The fluid capacity of the automatic transaxle is 7.8 litres.
WARNING:
The transaxle fluid level should be checked when the engine is at normal operating temperature. This means that the engine, radiator,exhaust system etc., are very hot so you should exercise great care not to burn yourself during thisprocedure. 1. Open the bonnet, being careful to
keep hands and clothing clear ofany moving parts.
2. Remove the transaxle dipstick, wipe it clean, reinsert the dipstick as far as it will go, then remove it again. Now check the fluid level on thedipstick. It should be in the "HOT" range on the dipstick.
