2003 Hyundai Coupe engine overheat

DRIVING YOUR HYUNDAI 2- 15
9. If the trailer has electric brakes, start your
vehicle and trailer moving, and then apply the trailer brake controller by hand to besure the brakes are working. This lets youcheck your electrical connection at the sametime.
10. During your trip, check occasionally to be sure that the load is secure, and that thelights and any trailer brakes are still working.
11. Avoid jerky starts, sudden acceleration or sudden stops.
12. Avoid sharp turns and rapid lane changes.
13. Avoid holding the brake pedal down too long or too frequently. This could cause the brakes to overheat, resulting in reduced brakingefficiency.
14. When going down a hill, shift into a lower gear and use the engine braking effect. When ascending a long grade, downshift the transaxle to a lower gear and reduce speedto reduce chances of engine overloadingand/or overheating.
15. If you have to stop while going uphill, do not hold the vehicle in place by pressing on theaccelerator. This can cause the automatictransaxle to overheat. Use the parking brakeor footbrake. NOTE: When towing check transaxle fluid more
frequently.
CAUTION:If overheating should occur when towing,
(temperature gauge reads near red zone), taking the following action may reduce oreliminate the problem.
1. Turn off the air conditioner.
2. Reduce highway speed.
3. Select a lower gear when going uphill.
4. While in stop and go traffic, place the gear selection in park or neutral and idle the engine at a higher speed.

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.

IN CASE OF EMERGENCY
SD060A1-E IN THE EVENT OF A PUNCTUREIf a puncture occurs whilst driving the vehicle:
1. Bring the car to rest as soon as it is safe to do so and with the minimum amount of braking required which will assist in main-taining the maximum amount of control. Thevehicle should be parked wherever possibleupon firm level ground to facilitate wheelchanging.
2. If the vehicle is creating a hazard and the road conditions do not permit the wheel to bechanged safely, assistance should be sought.
3. Passengers must not be allowed to remain inside the vehicle during wheel changing. Ifa puncture occurs whilst the vehicle is on a SD070A1-E CHANGING A FLAT TYRE
7. Proceed with caution until it is established
that the engine is operating normally. If the engine overheats repeatedly, the advice of aHyundai dealer should be sought.
CAUTION:Serious loss of coolant indicates there is aleak in the cooling system and this should bechecked as soon as possible by a Hyundaidealer.
It is of the utmost importance that care is exer-cised when changing road wheels. Ensure thatthe parking brake is set and that the gear shiftlever is in reverse (P, if the vehicle has automatictransaxle).
D040A01GK-EAT TEMPORARY SPARE TYREThe following instructions for the temporary spare tyre should be observed:
1. Check inflation pressure as soon as practical
after installing the spare tyre, and adjust to the specified pressure. The tyre pressure shouldbe periodically checked and maintained atthe specified pressure while the tyre is stored.
2. The spare tyre should only be used temporari-
ly and should be returned to the luggagecompartment as soon as the original tyre canbe repaired or replaced.
3. Continuous use at speeds of over 50 mph (80 km/h) is not recommended. 4. As the temporary spare tyre is specifically
designed for your car, it should not be used onany other vehicle.
5. The temporary spare tyre should not be used on any other wheels, nor should standardtyre, snow tyre, wheel covers or trim rings beused with the temporary spare wheel. If suchuse is attempted, damage to these items orother car components may occur.
6. The temporary spare tyre pressure should be checked once a month while the tyre is stored.
CAUTION:
o Do not use snow chains with your tempo- rary spare tyre.
o Do not use more than one temporary spare tyre at a time.

ways wash thoroughly after any contact. Keep used oils out of reach of children. It is illegalto pollute drains, water courses and soil. Useonly authorized waste collection facilitiesincluding civic amenity sites and garages forthe disposal of used oil and oil filters. If indoubt, contact the local authority for dis-posal instructions. SG050A1-E ENGINE COOLANT CHECKING AND REPLACING WARNING: Do not remove the radiator cap when the engine is hot, since the system is pressurizedand coolant may be ejected from the radiatorresulting in scalding. SG050B1-E Coolant recommendations
Only ethylene glycol based coolant with a corro- sion inhibitor suited to aluminium alloy enginecomponents should be used in the cooling sys-tem. No further additives or inhibitors should beused. The coolant specific gravity should bechecked as prescribed in the maintenance sched-ule to ensure adequate frost and corrosion pro-tection. In addition, the engine coolant must bereplaced at the specified interval since the corro-sion inhibitor properties deteriorate with time.It is important to note that whilst an increase in theconcentration of anti freeze gives an increase inthe level of frost protection, a solution which is inexcess of 65% anti freeze will result in reducedfrost protection and engine overheating. There-fore the recommended concentration of 50%should not be exceeded for general use.The use of methanol based anti freeze com-pounds may result in engine overheating and willinvalidate the vehicle warranty. NOTE: It is imperative that vehicles fitted with an airconditioning system have a coolant concen-tration of the recommended strength at alltimes. The use of the air conditioning systemwhen the cooling system is filled with wateronly will result in the heater matrix freezingand subsequently bursting.SG050C1-E Engine Coolant LevelThe 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 of thecorrect concentration until the level is betweenthe "LOW" and "Full" marks. If the level fallsbelow the "LOW" mark on a regular basis despitebeing topped up, consult a Hyundai dealer. SG050D1-E To Change the Engine CoolantThe engine coolant should be changed at those intervals specified in the vehicle maintenanceschedule in Section 5. NOTE: Care should be taken to ensure that coolantis not allowed to spill onto the paintworksince the finish may become damaged. Ifcoolant spillage occurs, the affected areashould be rinsed thoroughly with water.
1. Park the vehicle on level ground and ensure
that the parking brake is firmly applied, and the engine allowed to cool.DO NOT ATTEMPT THIS OPERATIONWHILST THE ENGINE IS HOT SINCEBURN-ING OR SCALDING MAY RESULT.
2. Prepare a suitable receptacle to collect the displaced coolant and position this under theradiator drain tap.

INFORMATION
The vehicle identification number (VIN) is unique to each individual vehicle and is the number(sometimes referred to as chassis number) usedupon the vehicle registration document to iden-tify the vehicle.The VIN will be found stamped upon a plateattached to the engine bulkhead. The engine number is stamped on the engineblock as shown in the drawing. I030A01GK-EAT TYRE PRESSURES In modern high-speed motoring, correct tyre pressures are vitally important. Incorrect tyrepressures can affect vehicle safety by causingreduced adhesion, steering response and tyrefailure through overheating. The tyre pressuremust only be checked when the tyres are cold.The correct tyre pressures are indicated on thelabel affixed to the drivers door pillar and below. Tyre pressures should be increased by 3 psi when the vehicle is driven fully laden or underconditions of sustained high speed motoring. SI030A2-E SNOW TYRES If it is desired to fit snow tyres to the vehicle, it must be ascertained that the original size andload carrying capacity are met by the replace-ment tyres. When using snow tyres, the vehicleshould not be driven at speeds in excess of 60MPH.
