F060H01A-AAT o Air Cleaner Filter A Genuine Hyundai air cleaner filter is recommended when the filter is re- placed. F060J01A-AAT o Spark Plugs Make sure to install new spark plugs of the correct heat range. F070B01A-GAT o Cooling System Check the cooling system part, such as radiator, coolant reservoir, hosesand connections for leakage and dam- age. Replace any damaged parts.
F060E01A-AAT
o Timing Belt
Inspect all parts related to the timing belt for damage and deformation. Re- place any damaged parts immediately. F060G01A-AAT
o Vapor Hose and Fuel Filler Cap
The vapor hose and fuel filler cap should be inspected at those intervals specified in the maintenance sched-ule. Make sure that a new vapor hose or fuel filler cap is correctly replaced. F060F01A-AAT
o Vacuum, Crankcase
Ventilation 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 withany 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. F060N02E-GAT
o Valve Clearance
Inspect excessive valve noise and/or engine vibration and adjust if neces- sary. A qualified technician shouldperform the operation.

SPARK PLUGS
WARNING:
The cooling fan is controlled by engine coolant temperature and may sometimes operate even when the engine is not running. Useextreme caution when working near the blades of the cooling fan so that you are not injured by arotating fan blade. As the engine coolant temperature decreases, the fan will automatically shut off. Thisis a normal condition. G060A01L
G060B02S-GAT
REPLACING THE SPARK PLUGS (Gasoline Engine)
The spark plugs should be changed
at the intervals specified in the ve- hicle maintenances schedule in Sec- tion 5 or whenever engine perfor-mance indicates they should be changed. Symptoms that suggest poor spark plug performance include en-gine misfiring under load, loss of fuel economy, poor acceleration, etc. When spark plugs are replaced, al-ways use spark plugs recommended by Hyundai. The use of other spark plugs can result in loss of perfor-mance, radio interference or engine damage.
Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm (0.028 ~ 0.032 in.)
NOTE: When replacing the spark plugs, genuine Hyundai replacement partsare recommended.

17CHANGING THE AIR CLEANER FILTER
NOTE: Spark plugs should be tightened firmly. Over-tightening can dam-age the threads in the aluminum cylinder head. Leaving them too loose can cause the spark plugs 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't fall off. G070A01E-AAT
