Bubble In Radiator

[92 acura da]

Hello Everyone, Have a lil issue with my integra! When my integra is on with the radiator cap off and running, little bubbles come to the top of the radiator. However, my car does not over heat. I would like to know what is causing those bubbles? I tried bleeding out the radiator and the bubbles still continue. Please Help Me With My Issue???

Have you replaced any cooling system components recently? Such as water pump, thermostat or any hoses? This could be air in the system working it's way out.

This could also potentially be a head gasket concern if it does not seem to stop, does the car overheat at all on the highway?
