What Causes the Sound of Water When Accelerating?
2 Answers
The sound of water when accelerating can be caused by water remaining in the pipes of the air conditioning system's heater core or residual water accumulation in the car. Water in the air conditioning system: The warm air from the heater comes from the circulation of the engine coolant. The pipes in this area are positioned relatively high, and after replacing the coolant, some air may remain trapped, which over time can form a certain amount of water accumulation. When cold water flows through the heater core, the driver may hear a water sound when accelerating. Residual water in the car: A loose or damaged exhaust pipe can lead to water accumulation inside the car. It is recommended to check if the water level in the car's radiator has decreased. If it has, the air inside the radiator should be purged to eliminate this water sound. Engine knocking: If the car makes a water sound when accelerating deeply, it may be due to engine knocking causing noise from the valves. It is advisable to check the cause of the knocking and add some anti-knock agents. Additionally, pay attention to the fuel grade when refueling. Avoid mixing fuels and do not use gasoline with a grade that does not match the car's recommended fuel grade. This can also help prevent the sound of water when accelerating.
I've been driving my old car for ten years, and last year I encountered a situation where I could hear water sounds whenever I stepped on the gas. At first, I thought it was just a minor issue of water splashing from the tires, but upon closer listening, the sound seemed to be coming from the engine side. A friend who works in auto repair told me it might be a leak in the coolant system's water pump, causing a gurgling sound as the coolant flows. Alternatively, water might have accumulated inside the exhaust pipe, making a splashing noise when accelerating due to pressure changes. In my case, I checked it myself and found the coolant reservoir's level was a bit low. After adding some fresh coolant, the sound reduced. I suggest you pop the hood before starting the car next time to check if the coolant level is normal and the color hasn't changed. If the noise persists, you should head to a repair shop quickly to avoid costly repairs or dangerous situations.
