I have just noticed a bubbling/gurgling noise coming from the passenger footwell/under glovebox area. Its almost like water is boiling, it starts happening the second the car is started even 1st thing in the morning when everything is ice cold, and it remains constant the entire time the car is on, doesnt change in sound at all. I usually listen to a good helping of rock music so maybe this has been happening forever but just not noticed it?? anyone else have this noise?

I hear it in my car...its more like water draining. I assumed it was the coolant going to/fr the radiators.

It's the optional expresso machine... LOL. Seriously, my car does that all the time, I brought it up to the service dept but they couldn't replicate it. I would at least take it to the dealer to create a paper trail if there are issues later on.

 

It's Mr. Fusion:

 

so im assuming everyone gets the noise and its perfectly normal...car is out of warranty so dont want to bring it to the dealer and spend $400 for them to tell me its normal

 

heater core!

 

i live in NJ and it did just start to get cold out recently...so if it is the heater core, that sound it is making is not an issue right? perfectly normal i am assuming

 

I have that same sound when the heat is on. I would love to know if anyone has an answer.

 

Fluid going to or from the radiators.

 

Glad to see this thread. I've also wondered what that sound is!

 

My old Supra did the same thing sounded like a waterfall behind the dash. I guess I get to look forward to it in the porsche soon.

 

drunk girl friend on the floor?

 

its the heater core filling with liquid from the radiator!

 

Another benefit of living in FL: No heater use so no strange noise.

 

xyzzy has got it, coolant flowing through the heater core. yes it does sound weird and not everycar makes the sound which is what i think is odd, but yes its the heater core
