What Causes Water Sound When Turning a Car?

[SanFrancisco]

It may be caused by water ingress in the car's sill or due to incomplete air bleeding in the cooling system where the radiator is installed at a higher position. Below is a detailed explanation: Introduction: The water flow sound from the front of the car is generally caused by incomplete air bleeding in the cooling system where the radiator is installed at a higher position or a clogged air conditioning drain. Solution: When the vehicle is parked, rev the engine hard to activate the electric fan several times, then open the radiator cap to release air, taking care to avoid burns from high water temperatures. Alternatively, check if there is water ingress inside the car's sill. Typically, there are rubber plugs at the bottom of the sill, and the door drain is located at the very bottom when the door is opened. You can inspect these areas.
