o Vacuum, crankcaseventilation hoses
Inspect the surface of hoses for evi- dence of heat and/or mechanical dam- age. Hard and brittle rubber, cracking, tears, cuts, abrasions, and excessiveswelling indicate deterioration. Particu- lar attention should be paid to examin- ing those hose surfaces nearest tohigh heat sources, such as the ex- haust manifold. Inspect the hose routing to assure that the hoses do not come in contact with any heat source, sharp edges or mov- ing component which might cause heatdamage or mechanical wear. Inspect all hose connections, such as clamps and couplings, to make sure they aresecure, and that no leaks are present. Hoses should be replaced immedi- ately if there is any evidence of dete-rioration or damage. 6ZF060H1-A
o Air cleaner filter
A Genuine Hyundai air cleaner filter is
recommended when the filter is re- placed.
6ZF060J1-A
o Spark plugs
Make sure to install new spark plugs
of the correct heat range.
F060N02E-EAT
o Valve Clearance
Inspect excessive valve noise and/or
engine vibration and adjust if neces- sary. A qualified technician should perform the operation. 6ZF070B1-A
o Cooling system
Check the cooling system part, such
as radiator, coolant reservoir, hosesand connections for leakage and dam- age. Replace any damaged parts.
6ZF070C1-A
o Coolant
The coolant should be changed at
the intervals specified in the mainte-nance schedule.
6ZF070D1-A
o Manual transaxle oil
Inspect the manual transaxle oil ac-
cording to the maintenance schedule. NOTE:
If the oil level is low, check for
possible leaks before adding oil. Do not overfill.

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.

0.039 ~ 0.043 in. (1.0~1.1 mm)
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

NOTE:
o When replacing the spark plug, genuine Hyundai parts are rec- ommended.
o It is recommended that the spark plugs for 2.7L Engines bechanged by an authorized Hyundai dealer.
*1. Platinum coated. *2. Iridium coated.
!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.

HGK5066 4. When preparing to remove the old
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.
