Why does my car make a bubbling sound when it overheats?
Bubbling Noise. When your car engine overheats, coolant enters the overflow container, resulting in a bubbling sound from the engine. If there are no other signs of overheating, a bubbling sound may indicate that there is air in the cooling system, which can lead to overheating later.
Why does my car over heat when idling?
Radiator Fan: If the car overheats when idling, the culprit is likely the radiator fan. This fan is designed to facilitate the interaction of cool air with the radiator for the purpose of lowering the temperature of the coolant contained within. If the fan isn’t spinning when the car is not in motion, there is little to no air cooling the radiator.
