Engine Coolant Level
SG050D1-E
To Change the Engine Coolant The engine coolant should be changed at
those intervals specified in the vehicle main- tenance schedule in Section 5.
NOTE:Care should be taken to ensure that cool-
ant is not allowed to spill onto thepaintwork since the finish may becomedamaged. If coolant spillage occurs, theaffected area should be rinsed thoroughlywith water. The engine coolant level may be observed
through the side of the plastic coolant reservoir(expansion tank) when the engine is cold. If thelevel is below the "LOW" mark, add coolant ofthe correct concentration until the level is be-tween the "LOW" and "Full" marks. If the levelfalls below the "LOW" mark on a regular basisdespite being topped up, consult a Hyundaidealer. 1. Park the vehicle on level ground and en-
sure that the parking brake is firmly ap-plied, and the engine allowed to cool. DO NOT ATTEMPT THIS OPERATION WHILST THE ENGINE IS HOT SINCEBURNING OR SCALDING MAY RESULT.
2. Prepare a suitable receptacle to collect the displaced coolant and position this under theradiator drain tap.
3. With the heater temperature control set to the "HOT" position, remove the radiator capand open the radiator drain tap.
4. When the engine coolant has drained com- pletely, close the drain tap ensuring that thisis not over tightened.
5. Prepare a suitable quantity of new engine coolant (refer to section 9) and pour thisinto the radiator.
6. Start the engine with the radiator cap still removed and continue to add coolant as thelevel decreases as air is expelled from thesystem. When the level remains constant,replace the radiator cap and replenish thecoolant reservoir.
7. When the engine is hot, check to ensure that no coolant leaks are present.
WARNING: The cooling fan is controlled by engine coolant temperature and may sometimesoperate even when the engine is not run-ning. Use extreme caution when workingnear the blades of the cooling fan so that

NOTE: It is imperative that vehicles fitted with an
air conditioning system have a coolant concentration of the recommended strengthat all times. The use of the air conditioningsystem when the cooling system is filledwith water only will result in the heatermatrix freezing and subsequently bursting.

Checking the Refrigerant
1. Start the engine and run at idle for several minutes with the refrigeration system run- ning at the coldest setting.
2. Open the bonnet and inspect the sight glass on the top of the receiver dryer.
3. If the refrigerant charge is insufficient, a flow of bubbles will be observed through the sightglass.
4. If the refrigerant charge is satisfactory, no bubbles will be observed through the sightglass.
CAUTION: Running the air conditioning system with a
low refrigerant level may damage the com- pressor.
SG140D1-E
Off Season Maintenance The air conditioning must be run for ten minutes
or so weekly during periods when the systemwould not normally be used to ensure that thecompressor and seals are lubricated. If thisprecaution is not observed the compressor sealsmay become stuck to the compressor shaft anddamaged when the system is next used result-ing in a loss of refrigerant and damage to thecompressor.

Steering wheel freeplay should be checked to
ensure that the specified value is not exceeded.

Compressor Drive Belt
The air conditioning compressor drive belt
should be checked to ensure freedom from damage or excessive wear and correct ten-sion. The belt tension is correct when the beltdeflects by about 0.3 inches (8 mm) when aforce of 98 N is applied to the belt halfwaybetween the compressor and crankshaft SG140A1-E

MAINTENANCE
Condenser Ensure that the condenser is periodicallyinspected and that accumulations of dirt, deadinsects and leaves etc, are removed to ensurethat the efficiency of the system is not impaired.Care must be exercised to ensure that thecondenser fins are not damaged during clean-ing.

ELECTRIC COOLING FANS
WARNING: The cooling fan is controlled by engine coolant temperature and may sometimesoperate even when the engine is not run-ning. Use extreme caution when workingnear the blades of the cooling fan so thatyou are not injured by a rotating fan blade.As the engine coolant temperature decreas-es, the fan will automatically shut off. Thisis a normal condition. The engine cooling fan should operate before the temperature gauge reaches the upper por-tion of the scale and the condenser fan shouldoperate whenever the air conditioning is in use. The power steering fluid level should bechecked daily. To check the power steering fluid level, be sure the ignition is "OFF", then check to makecertain that the power steering fluid level isbetween the "MAX" and "MIN" level markingson the fluid reservoir. NOTE: Grinding noise from power steering pump may be heard immediately after the engineis started in extremely cold condition(below -4°F). If the noise stops during warmup, there is no abnormal function in thesystem. This is due to a power steeringfluid characteristic in extremely cold con-ditions.

WARNING:
Motor vehicle batteries contain sulphuric
acid which is corrosive and poisonous. Hy- drogen gas is emitted from the battery whichis explosive when combined with oxygen.The following precautions must be strictlyobserved to avoid personal injury or dam-age to the vehicle.
o If battery electrolyte is spilled onto skin or into eyes, the effected area must be flushed with copious amounts of water and medicalassistance sought.
o If battery electrolyte is ingested, copious amounts of water or milk followed by an ant-acid (raw egg or milk of magnesia) must bedrunk. Vomiting should not be induced andmedical assistance must be sought.
o Batteries must only be charged in well venti- lated areas from which naked lights or sourc-es of sparks are excluded.
o Ensure that children, pets or other unautho- rized persons are kept away from batteries.
o Do not allow anything to bridge the positive (+) and negative (-) terminals of the battery.
o Never invert the battery.
The battery fitted during production is of the
"Maintenance Free" type.
