Default A different overheating problem

Hears a tricky one for you fellas.

1st, yes, I did extensive searches. Nothing for thsi particular issue..

Heres the issue. After the coolant system is bled, everything works fine, so long as the vehicle is driven daily. If it sits for more than 4 days, it seems to get air in the system agian. Overheats everytime.

Any thoughts?

Small leak in radiator cap? It makes sense that when it sits that would cause negative pressure "suck air" when running complete opposite. You can test the system for leaks. I woul start there
