2007 Pontiac G6 Question: Water sound when pressing on the gas pedal

 

Question

Visitor, Huntsville, AL, September 09, 2010, 11:08

When I turn on the car and press on the gas the engine sounds like water swishing through. This happens even if the air conditioner is off. A/C is working just fine.

    I have this same model, same year, and the same odd swishing noise, like there's a waterway in my engine compartment. Have you gotten any answers yet?

    I have the same problem too.. '08 Grand Prix...I just heard back from the dealership and they recommended a complete coolant flushing/refill as there is "probably and air pocket" in the system causing the swooshing sound. I didn't feel like spending the $150.00 to have that done!
