Hello,

I hear a noise that I would describe as water boiling coming from behind of the dashboard.
It is easy to notice when doing sharp turn or driving from even to uneven roads.

Any suggestion?

Thank you.

Is the radiator low?

Is the AC running (defrost mode makes it run even though the light is off)

Coolant fluid in the radiator isn't low and AC isn't running (not even defrost).

So it's rattles or something? Rolling noises?



How about trash rolling back and forth in the wiper area? My yard has a couple sweetgum trees, they drop these awful little bombs

It really sounds like boiling/sloshing water. Noise level starts low when the engine is cool but the more I drive it the louder it gets.

Water boiling noise....that's an unusual description....not ringing any bells yet.
Got a recording/video?


Have you tried to narrow down a specific area it originates from? Inside the dash, or in the engine compartment?
Tire/suspension?
Does it vibrate instead of make noise? Both noise and vibration?

Check your inner fenders, Maybe there plugged up with leaves and mud. Not sure it can happen on a Honda but I once had a 69 Firebird Convertible and both front and back would get stopped up and fill up a foot high before coming in on carpet

Your heater water valve may be inoperative , partially stuck?
