it could be as simple as the radiator cap not working as it should. ur radiator cap will release/draw coolant as needed.orrrrr combustion pressure getting into the cooling system from ur head gasket.
I really hope its not a headgasket haha i have zero coolant loss and the overflow doesn’t bubble at all… switched rad cap and it seems to be better also think i overfilled coolant a little it was right up to the brim of the neck on the rad and kept spilling over when i took rad cap off while running…
