I’ve noticed within the past year that when I start my Honda Fit Sport 2008 it sounds like water is rushing in my dash when the car moves. Any ideas what this could be? My husband already checked and the coolant level is fine.
Could be the sound of refrigerant going through the evaporator coil.
Check the air conditioner’s drain hose to make sure it isn’t clogged or kinked.
There might be air in the cooling system and the sound you hear is the bubbles running through the heater core.
