At times I hear a bubbling or gurgling sound (sorry thats the best way i can describe it) sounds like under my dash. I was wondering if this might be a problem with my heater core. A friend told me that sometimes the system can get air bubbles in it and might need to be flushed. Anyone have an idea how this is done? DIY, or shop needs to do it? Or any other ideas as to what might be causing this noise. Thanks in advance for your help.

A quick search should yield the results you seek. Most likely this is caused by a low coolant level in the cooling system. The related threads menu at the bottom of the page give some good instruction on various heater core and cooling system related maintenance.
