Gurgling sound when idling

[GroovyGeek]

Does anyone's Bronco make a "gurgling" sound while idling, as if a small stream is running under the Bronco. It is fairly subtle, I can't hear it in town due to the high ambient background, but when I go offroad it is pretty easy to pick up.

Yup.

Normal?

I've never had a vehicle make that sound but it doesn't seem to be a symptom of anything harmful and it's been making the noise since new.
So yes?
I believe it's coolant moving through the heater core.

Possible air trapped in the cooling system. You may need to purge it out. I had this happen to me on other vehicles. Don’t think anything bad will happen, but it is definitely annoying to hear.

I put Listerine in mine for this reason

I hope that is a joke that references the gurgling sound and not something you did in reali life.
