Bubble Bubble

Sat in my car yesterday and after I shut it off I heard what sounded like a bubbling type of sound. Is this the radiator cooling down or something?
Is this normal?

yeah i believe its normal, i think its the coolant moving around inside the engine or radiator. i dunno but if you listen closely mine always does it after you shut it off, but its gotta be quite. i believe my dads truck does it too.

agreed! It is... first time I heard that, I was about to change the fluid in the rad anyway... so I went ahead and did it a little earlier... topped it off and didn't have that sound anymore, which leads me to believe that I was just a little low on fluid...

Its coolant noise coming from the Heater Core. Nothing to worry about.Just remember to make sure that Your coolant level is good & when Your warranty runs out..... drain the (garbage) Dexcool & replace it with the green coolant.
