Swooshing sound under the passenger side
There is a swooshing sound under the passenger side of my truck. Sounds like water swooshing back and forth. Anyone have any ideas what this might be. There is no water on the actual floor of the truck.

My 1996 F150 did the same. When I replaced the thermostat, I "burped" the cooling system. That was over two months ago, and it hasn't happened since.
Edited to say, I believe there was air in the system and the void was letting coolant rush in and out of the heater core.
