Bad thermostat maybe?
Cooling system leak or engine overheating and steam escaping from the radiator cap.Cooling system leak or engine overheating and steam escaping from the radiator cap.
Yes, a radiator leak can cause the coolant levels to drop, leading to overheating. The radiator is responsible for cooling the engine, so a leak can disrupt the cooling process and result in the engine overheating.
Replace the thermostat and radiator cap.
Hyundai got excellent cooling system, you might have a little hole in your radiator that affects cooling circulation pressure? check if you have tight cooling system pressure.COCORICO
No, there should not be pressure in the radiator after cooling down. If there is still pressure, it could indicate a problem with the radiator cap or the cooling system, such as a leak or a failing pressure release valve.
It could be caused by a defective pressure cap on the radiator cooling system.
Overheating, and rapid cooling.
If you replaced some of theses already ignore and go down the line # Not enough coolant # Water pump drivebelt defective or out of adjustment # Radiator core blocked or grille restricted # Thermostat faulty # Electric cooling fans blades broken or cracked # Radiator cap not maintaining proper pressure # Ignition timing incorrect
Radiator plugged or restricted? Cooling system airbound? Water pump not circulating coolant? Radiator cap defective? Radiator hoses collapsing under pressure? Defective gauge/cooling temperature sensor?
The radiator cap controls cooling system pressure.The radiator cap controls cooling system pressure.
The cooling system is under pressure and opening the cap can spray you (and other things) with very hot coolant.
Low coolant? Radiator plugged or restricted? Water pump not circulating coolant? Thermostat not opening? Cooling fan not working? Hoses collapsing under pressure Defective radiator cap?
