o 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 with any heat source, sharp edges or mov-ing component which might cause heat damage or mechanical wear. Inspect all hose connections, such as clampsand couplings, to make sure they are secure, and that no leaks are present. Hoses should be replaced immedi-ately if there is any evidence of dete- rioration or damage. 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.
F060N02E-AAT
o Valve Clearance
Inspect excessive valve noise and/or
engine vibration and adjust if neces- sary. A qualified technician should perform the operation. F070B01A-GAT o Cooling System Check the cooling system part, such as radiator, coolant reservoir, hoses and connections for leakage and dam- age. Replace any damaged parts. F070C01A-AAT o Coolant The coolant should be changed at the intervals specified in the mainte-nance schedule. F070D01A-AAT 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.

o The engine oil consumption is strongly effected by the viscosity and quality of oil, engine rpm and driving condition etc. More engine oil may be consumed under severedriving conditions such as high speeds, frequent acceleration and deceleration, compared to normaldriving condition. G050B01A-AAT Recommended Engine Coolant Use a high quality ethylene-glycol coolant in a 50/50 mix with water. The engine coolant should be compatible with aluminum engine parts. Addi-tional corrosion inhibitors or additives should not be used. The cooling sys- tem must be maintained with the cor-rect concentration and type of engine coolant to prevent freezing and corro- sion. Never allow the concentration ofantifreeze to exceed the 60% level or go below the 35% level, or damage to the cooling system may result. Forproper concentration when adding or replacing the engine coolant, refer to the following table.

CHECKING AND CHANGING THE ENGINE COOLANT
G050A02A-AAT
WARNING:
Do not remove the radiator cap when the engine is hot. When the engineis hot, the engine coolant is under pressure and may erupt through the opening if the cap is removed. Youcould be seriously burned if you do not observe this precaution. Do not remove the radiator cap until theradiator is cool to the touch. NOTE: It is recommended that the engine
coolant should be changed by an authorized Hyundai dealer.

G050C01A-AAT To Check the Coolant Level
The coolant level can be seen on the
side of the plastic coolant reservoir. The level of the coolant should be between the "L" and "F" lines on the reservoir when the engine is cool. Ifthe level is below the "L" mark, add engine coolant to bring it up between "L" and "F". If the level is low, inspectfor coolant leaks and recheck the fluid level frequently. If the level drops again, visit your Hyundai dealer for aninspection and diagnosis of the rea- son. G050D02A-AAT 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.
CAUTION:
Engine coolant can damage the fin- ish of your car. If you spill engine coolant on the car, wash it off thor- oughly with clean water.
!
1. Park the car on level ground, set the parking brake and remove the radia- tor cap when cool.
2. Be sure your drain receptacle is in place. Open the drain cock on the radiator. Allow all the engine cool-ant to drain from the cooling sys- tem, then securely close the drain cock.
3. Check Section 9 for the capacity of the cooling system in your car.Then, following the manufacturer'sdirections on the engine coolant container, add the appropriate quantity of engine coolant to theradiator. 4. Turn the radiator cap counterclock-
wise without pressing down on it,until it stops. This relieves any pres- sure remaining in the cooling sys- tem. And remove the radiator capby pushing down and turning coun- terclockwise. Now fill the radiator with clean dem- ineralized or distilled water. Con- tinue to add clean demineralized ordistilled water in small quantities until the fluid level stays up in the radiator neck.

11CHANGING THE AIR CLEANER FILTER
G070A01E-AAT To change the filter, unsnap the clips
around the cover. When this is done, the cover can be lifted off, the oldfilter removed and the new filter put in its place. Genuine Hyundai Replace- ment Parts are recommended.
HGK5010G050D04E
!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 coolant fanso that you are not injured by a rotating fan blade. As the engine coolant temperature decreases, thefan will automatically shut off. This is a normal condition.
5. Start the engine, top off the radiator
with water and then add engine coolant to the reservoir until the level is between "L" and "F".
6. Replace the radiator and reservoir caps and check to be sure thedrain cocks are fully closed and not leaking.

To Check the Transaxle Fluid Level
1.6/2.0L 2.7L
The automatic transaxle fluid level should be checked regularly. Keep the vehicle on level ground with the parking brake applied and check the fluid level according to the follow-ing procedure.
1. Place the shift lever in N(neutral) position and confirm the engine isrunning at idle speed.
2. After the transaxle is warmed up
sufficiently [fluid temperature70~80°C (158~176°F)], for example by 10 minutes usual driving, move the shift lever through all positionsthen place the shift lever in N(neutral) or P(park) position. 3. Confirm if the fluid level is in the
“HOT” range on the level gauge. Ifthe fluid level is lower, add the specified fluid from the fill hole. If the fluid level is higher, drain the fluid from the drain hole.
4. If the fluid level is checked in cold condition[fluid temperature 20~30°C(68~86°F)], add the fluid to the“COLD” line and then recheck the fluid level according to the above step 2.

!WARNING:
The cooling fan is controlled by engine coolant temperature andmay sometimes operate even when the engine is not running. Use extreme caution when workingnear the blades of the cooling fan, so that you are not injured by a rotating fan blade. As the enginecoolant temperature decreases, the fan will automatically shut off. This is a normal condition.
Fluid level should be within this
range
