6-8 5. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully closed and not leaking.
WARNING: The cooling fan is controlled by engine cool- ant temperature and may sometimes oper-ate even when the engine is not running.Use extreme caution when working near theblades of the coolant fan so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition. G060A02Y-GAT
SPARK PLUGS

Your engine was originally equipped with plati- num-tipped spark plugs. (For 2.7L only). Platinum-tipped spark plugs will last longer than conventional type spark plugs and can be iden-tified by blue lines on the ceramic shell. NOTE: Do not clean or regap platinum-tipped spark plugs.
G060B01GK-GAT
Replacing the Spark Plugs The spark plugs should be changed at the
intervals specified in the vehicle maintenanceschedule in Section 5 or whenever engine per-formance indicates they should be changed.Symptoms that suggest poor spark plug perfor-mance include engine misfiring under load, lossof fuel economy, poor acceleration, etc. Whenspark plugs are replaced, always use sparkplugs recommended by Hyundai. The use ofother spark plugs can result in loss of perfor-mance, radio interference or engine damage.
NOTE: When replacing the spark plugs, genuine
Hyundai replacement parts are recom- mended. Recommended Spark Plugs:

To Change the Engine Coolant
The engine coolant should be changed at those
intervals specified in the vehicle maintenance schedule in Section 5.
NOTE: Engine coolant can damage the finish of
your car. If you spill engine coolant on the car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park- ing brake and remove the radiator cap when cool.
2. Be sure your drain receptacle is in place. Open the drain cock on the radiator. Allowall the engine coolant to drain from thecooling system, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car. Then, followingthe manufacturer's directions on the enginecoolant container, add the appropriate quan-tity of engine coolant to the radiator.
4. Turn the radiator cap counterclockwise with- out pressing down on it, until it stops. Thisrelieves any pressure remaining in the cool-ing system. And remove the radiator cap bypushing down and turning counterclockwise. Now fill the radiator with clean demineral- ized or distilled water. Continue to add cleandemineralized or distilled water in small quan-tities until the fluid level stays up in theradiator neck. DOHC1.0~1.1 mm (0.039 ~ 0.043 in.)

Checking the Compressor Drive Belt
When the air conditioning is being used regular- ly, the compressor drive belt tension should bechecked at least once a month. To check the drive belt tension, press down on the belt halfway between the engine crankshaftand compressor pulleys. Pressing with yourfinger, you should not be able to deflect this beltanymore than 8.0 mm. If you have the instru-ments to check it with a force of 98N (22 lb.),the deflection should be approx. 8.0 mm (0.315inches). If the belt is too loose, have it adjustedby your Hyundai dealer. A/C

To Replace the Fluid
Recommended brake fluid conforming to DOT
3 or DOT 4 specification should be used. Thereservoir cap must be fully tightened to avoidcontamination from foreign matter or moisture.
NOTE: Do not allow any other liquids to contami-
nate the brake fluid. Seal damage will result.
WARNING:Use caution when handling brake fluid. It
can damage your vision if you get it in your eyes. It will also damage your vehicle's paintif spilled on it and not removed immediately.

SB215B1-E ENGINE COOLANT TEMPERATURE GAUGE engine is hot may cause hot water and steam to be ejected from the radiator resulting inburns and scalding. The radiator cap mustonly be removed when the engine has cooled.Do not add cold water to a hot engine to avoidthe possibility of engine damage. The use ofplain water in the cooling system is not rec-ommended since the aluminium componentsof the cooling system require the use of acorrosion inhibitor found in the recommendedEthylene Glycol type anti freeze solutions.
The engine coolant temperature gauge indicatesthe engine coolant temperature and will, undernormal circumstances, give an indication in the"Normal" or centre portion of the scale. Shouldthe indication move into the upper or "Hot" por-tion of the scale, engine overheating is indicated.Under these circumstances, the vehicle shouldbe brought to rest as soon as is safe to do so andthe engine turned off. Once the engine has cooledsomewhat, the coolant level and the condition ofthe generator/water pump drive belt should bechecked. If the cause of the overheating cannotbe readily established, the assistance of aHyundai dealer should be sought. WARNING: The engine cooling system is pressurizedand removal of the radiator cap when the The tachometer registers the speed of the enginein revolutions per minute (R.P.M.). CAUTION: The maximum safe engine operating speed isindicated by the white zone of the tachometerscale. The engine should not be operatedbeyond the beginning of this zone or seriousengine damage may result.

WARNING: Fuel vapours are dangerous. Before refuel- ling, turn off the engine and never allowsparks, lit cigarettes or open flames near thefiller area. When releasing the filler cap, asmall amount of residual pressure may gen-erate a slight hissing sound which is notindicative of an abnormality. In the event ofthe fuel filler cap requiring replacement, onlya Genuine Hyundai replacement part shouldbe used to prevent fuel leakage.

IN CASE OF EMERGENCY
3-2 4. Check to see if the water pump drive belt is
missing. If it is not missing, check to see that it is tight. If the drive belt seems to be satisfac-tory, check for coolant leaking from the radia-tor, hoses or under the car. (If the air condi-tioning had been in use, it is normal for coldwater to be draining from it).
WARNING:Whilst the engine is running, keep hands andclothing away from moving parts such as thefan and drive belts to prevent injury.
5. If the water pump drive belt is broken or coolant is leaking out, stop the engine imme- diately and call the nearest Hyundai dealerfor assistance.
WARNING:Do not remove the radiator cap when theengine is hot since steam and boiling watermay be ejected from the radiator resulting inburns or scalding.
6. If the cause of the overheating cannot be found, wait until the engine temperature has returned to normal. Then, if coolant has beenlost, carefully remove the radiator cap andadd water to bring the fluid level in the reser-voir up to the base of the radiator fill opening.Fill the coolant expansion tank to the halfwaymark.
WARNING:Motor vehicle batteries contain sulphuric acidand emit hydrogen gas. Protective clothingshould be worn and care exercised to preventthe acid from coming into contact with skin orclothing and the vehicle. Naked lights shouldnot be permitted in the vicinity of the battery.Care should be exercised to prevent sparksoccurring during connection. If acid acciden-tally comes into contact with skin or eyes, theaffected area should immediately be flushedwith copious amounts of water and medicalassistance sought.
1. Ensure that the booster battery is 12 volt type.
If the booster battery is installed in another vehicle, ensure that the two vehicles are nottouching.
2. Turn off all unnecessary electrical equipment in both vehicles.
3. Ensure that the engine of the vehicle provid- ing the jump start is running prior to connec-tion of the jump cables.
4. Connect the red jump cable to the positive (+) terminal of the booster battery and the otherend to the positive (+) terminal of the dis-charged battery.
5. Attach the black jump cable to the negative (-) terminal of the booster battery, and theother end to a ground point within the enginecompartment of the vehicle with the flat bat-tery. Do not connect to the negative batteryterminal of the flat battery since sparks maybe generated with the subsequent risk ofexplosion. 6. Raise the booster vehicle engine speed to
2,000 r.p.m. and start the engine of the vehi-cle with the flat battery.
7. Remove jump cables in the reverse order of installation (black cable first).
CAUTION:If the jump cable is incorrectly installed, dam-age to the vehicle electrical system may oc-cur, in particular the electronic componentssuch as the Fuel Injection system computerand the Automatic Transaxle computer. Thebattery must never be disconnected whilstthe engine is running. SD040A1-E IF THE ENGINE OVERHEATSIf the temperature gauge indicates overheating:
1. Pull off the road and stop as soon as it is safe to do so.
2. Place the gear selector lever in "P" (auto- matic), or neutral (manual transaxle) and set the parking brake. If the air conditioning is on,turn it off.
3. If coolant is running out under the car or steam is coming out from under the bonnetstop the engine. Do not open the bonnet untilthe coolant has stopped running or the steam-ing has stopped. If there is no visible loss ofcoolant and no steam, leave the engine run-ning and check to be sure the engine coolingfan is operating.If the fan is not running, turn the engine off.
