Rep Power: 302

My car makes a bubbly or boiling noise from the passenger airbag in the dash area. What is it? I've never had a car with airbags so i'm not familiar if it's a common noise in vehicles with airbags. Any help?

its normal, its only the coolant being circulated around the heat core.

You just need to bleed out the air bubbles. Mine did this when we changed the coolant. Just take off the radiator cap, start car, turn AC on so the fans kick on, turn it off after a minute, and you should see bubbles coming out on the fluid. Do that a few times until most of the bubbles come out. Then turn off car and replace the radiator cap.
