1. Turn off the roadway and stop in a safe place.
2. Set the selector lever to position «R» (by car with automatic transmission) or switch to neutral (by car with automatic transmission) and apply the parking brake. If the air conditioner is running, turn it off.
3. If coolant is leaking from under the vehicle or steam is coming out from under the hood, stop the engine. Do not open the hood until the coolant stops flowing or steam from under the hood stops. If there are no visible coolant leaks or fumes, keep the engine running and check that the cooling fan is working. If the fan does not work, stop the engine.
4. Check if the water pump drive belt is in place. If it is in place, check its tension. If the belt is OK, check for coolant leaks from the radiator, hoses and under the vehicle (condensation from the air conditioner flows under a parked car, if it is turned on).
Warning: When the engine is running, make sure that there are no (fan, drive belt) hair, hands or clothes are not caught, which will cause injury.
Warning (Diesel vehicles only): Do not carry out any work on the fuel injection system with the engine running or less than 30 minutes after it has stopped. The high pressure fuel pump, fuel rail and high pressure fuel lines are still under high pressure for some time after shutdown. A jet of high pressure fuel can cause serious injury if the system is leaking. Persons using cardiac stimulants should not be closer than 30 cm from the injection system control unit and wiring in the engine compartment during engine operation, because. high voltage currents in the injection system «common rail» generate a strong magnetic field.
5. If the water pump drive belt breaks or coolant leaks, stop the engine immediately and contact your nearest Hyundai dealer for assistance.
Warning: Do not open the radiator cap when the engine is hot. Doing so may eject coolant from the radiator, causing severe burns.
6. If you are unable to determine the cause of overheating, wait until the engine has cooled down to normal temperature. Then, if there is a coolant leak, carefully open the radiator cap and add this amount of coolant to it (see here), so that its level is between the marks on the expansion tank.
7. Continue driving carefully, watching for signs of overheating again. If the engine overheats again, contact your Hyundai dealer for assistance.
Attention: A rapid drop in the coolant level indicates a leak in the cooling system, which should be repaired by your Hyundai dealer as soon as possible.
