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.

o If battery electrolyte is spilled onto
skin or into eyes, the effected area must be flushed with copious amounts of water and medical assis-tance sought.
o If battery electrolyte is ingested, copious amounts of water or milkfollowed by an ant-acid (raw egg ormilk of magnesia) must be drunk. Vomiting should not be induced and medical assistance must besought.
o Batteries must only be charged in well venti-lated areas from which naked lights or sources of sparks are excluded.
o Ensure that children, pets or other unautho-rized persons are keptaway from batteries.
o Do not allow anything to bridge the
positive (+) and negative (-) termi-nals of the battery.
o Never invert the battery.
The battery fitted during production isof the "Maintenance Free" type.
ELECTRIC COOLING FANS
!
YG210A1-E
WARNING:
The cooling fan is controlled by engine coolant temperature and may sometimes operate even whenthe engine is not running. Do not touch the radiator fan until it is completely stopped.As the coolant temperature de-creases the fan will automaticallyshut off. This is a normal condi- tion.
Checking Engine Cooling Fan The engine cooling fan should auto- matically come on if the engine cool-ant temperature is high.
Checking Condenser Cooling Fan The condenser cooling fan (in front of the condenser) should come on auto- matically whenever the air conditioneris in operation.
POWER STEERING HOSES
YG220A1-E It is suggested that you check the power steering hose connections for fluid leakage at those intervals speci- fied in the vehicle maintenance sched-ule in Section 5. The power steering hoses should be replaced if there are severe surface cracking, pulling, scuff-ing or worn spots. Deterioration of the hoses could cause premature failure. NOTE: The power steering pump may be noisy when the engine is firststarted in the extreme cold (-4°F). This noise is not abnormal and will stop as the engine warms up.If the power steering pump contin- ues to be noisy after the engine has warmed up, have it inspectedby your Authorized Hyundai Dealer.

7EMISSION CONTROL SYSTEMS

SH010A1-E (Not all models) Depending upon the market for which the vehicle is destined, the emission control system will comprise one or more of the following emission controldevices.
(1) Crankcase emission control sys-
tem
(2) Evaporative emission control sys- tem
(3) Exhaust emission control systemIn order that the proper functioning of the emission control systems may be ensured, it is recommended that the vehicle is inspected and maintainedby an authorized Hyundai dealer in accordance with the maintenance schedule in this manual. EMISSION CONTROL SYS- TEMS
SH010B1-E
1. CRANKCASE EMISSION CON- TROL SYSTEM The positive crankcase ventilation system is employed to prevent air pollution caused by blow-by gases being emitted from the crankcase byintroducing fresh air to the crankcase through the air cleaner where this mixes with blow-by gases and thenpasses through the PCV valve into the intake manifold from where it sub- sequently enters the combustionchamber and is burned.
SH010C1-E
2. EVAPORATIVE EMISSION
CONTROL SYSTEM
The Evaporative Emission Control
System is designed to prevent fuelvapours from escaping into the atmo-sphere through the fuel tank ventila- tion system. SH010D1-E
3. EXHAUST EMISSION
CONTROL SYSTEM
The exhaust emission control system
is a highly effective system which controls exhaust emission while main- taining good vehicle performance. Whilst the engine is not running, fuel vapours generated inside the fuel tankare absorbed and stored in a char- coal canister. When the engine is started, the vapours stored in thecanister are drawn into the induction system through the purge control so- lenoid valve and are subsequentlyburned.The purge control solenoid valve iscontrolled by the ECU; when the en-gine coolant temperature is low or the engine is idling, the purge control valve is closed and fuel vapours re-main stored in the canister. Under normal running conditions when the engine is warm, the valve opens andthe vapours are drawn into the inlet tract and subsequently burned in the combustion chamber.
