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.

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

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:

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.

1. To check the transaxle lubricant level, the vehicle should be placed on level ground and the level plug removed with a suitable spanner.
2. If the level is correct, lubricant should begin to drip from the plugorifice. In this case the plug shouldbe replaced.If the level is incorrect, lubricantshould be added until it begins to drip from the plug orifice at which time the plug should be replaced. To Check the Transaxle Oil Level
Park the car on level ground with the
engine off.
1. Using a wrench of the correct size, loosen the oil filler bolt turning it counterclockwise and remove it with your fingers.
2. Use your finger to feel inside the
hole. The oil level should be at itsbottom edge. If it is not, check for leaks before adding oil. To refill the transaxle or bring the oil level up,add oil slowly until it reaches the proper level. Do not overfill.
3. Replace the bolt and washer, screw it in with your fingers and thentighten securely with the wrench.

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.
