raditor bubbles

[rics8]

Hello, I have a 2012 g37. It was over heating.
I change the termostat, radiator and cap. I fillied it last night drove it and now in the moring the filler has no coolant and looks empty. I added about 16oz while on and it is still has bubbles a day later. Is that ok.

Thanks

If you didn't bleed the system then your bubbles may simply be air gradually purging itself from the high points in the cooling system. If that's the case it will stop using coolant after a short while. If it keeps using coolant and the bubbles don't disappear then you probably have a blown head gasket.
