Engine Coolant Level
The engine coolant level may be
observed through the side of the plas- tic coolant reservoir (expansion tank) when the engine is cold. If the level is below the "L" mark, add coolant ofthe correct concentration until the level is between the "L" and "F" marks. If the level falls below the "L" mark on aregular basis despite being topped up, consult a Hyundai dealer. SG050D1-E
To Change the engine Coolant
The engine coolant should be changed at those intervals specified in the ve- hicle maintenance schedule in Sec- tion 5. NOTE: Care should be taken to ensure that coolant is not allowed to spill onto the paintwork since the fin- ish may become damaged. If cool-ant spillage occurs, the affected area should be rinsed thoroughly with water.
1. Park the vehicle on level ground and ensure that the parking brake is firmly applied, and the engine allowed to cool.DO NOT ATTEMPT THIS OPERA-TION WHILST THE ENGINE ISHOT SINCE BURNING OR SCALDING MAY RESULT.
2. Prepare a suitable receptacle to collect the displaced coolant andposition this under the radiator drain tap. 4. When the engine coolant has
drained completely, close the drain tap ensuring that this is not over tightened. G050D03E
3. With the heater temperature con-
trol set to the "HOT" position, re-move the radiator cap and open the radiator drain tap.

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.

Replacing the Spark Plugs
The spark plugs should be changed at the intervals specified in the ve-hicle maintenance schedule in Sec- tion 5 or whenever engine perfor- mance indicates they should bechanged. Symptoms that suggest poor spark plug performance include en- gine misfiring under load, loss of fueleconomy, poor acceleration, etc. When spark plugs are replaced, al- ways use spark plugs recommendedby Hyundai. The use of other spark plugs can result in loss of perfor- mance, radio interference or enginedamage. TYPE

spark plug, guide the socket down over 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.
6. To install the new spark plug, guide the socket down over the spark plug, being careful not to damage the ceramic insulator.
G060C02GK-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 engine rocker cover.
(1.6L/2.0L Engine)
NOTE: It is recommended that the spark plugs for 2.7L Engine should be changed by an authorized Hyundaidealer. 2. Using a clean cloth, remove any
dirt that has accumulated aroundthe 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 insulatedconnector, not the cable. Pullingon the cable may damage the car- bon core conductor.
HGK5062 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.

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.
