hahahahahahahaha funniest thing i have EVER heard. first off, your friend doesn't know anything about cars because u can't hear the "sloshing" of a radiator coolant because there is too much noise and there is no need for sloshing it's a constant flow of coolant.

Here is your answer: in order for the "magic seats" to work in our cars, Honda placed the gas tank underneath the driver and passenger seat. That sloshing noise is coming from your gas tank. We all have heard it, some louder then others. U hear it a lot on like 1/2 a tank when ur driving hard. So no, u have nothing 2 worry about it's normal.
