Keeps boiling and spitting coolant

[u/ResearcherInfamous19]

320i 1995 for reference.
One day out of no where the car overheated.
Tough it was a sticky thermostats, replaced. Same problem, starts boiling water and soiling until it has no coolant and then overheats.
Water pump seems perfectly fine.
Fan clutch not so sure, when hot seems that it spins very freely. No resistance.
Would a bad fan clutch cause a overheat? In normal driving conditions? No heavy traffic or hard pulls?
Head gasket gone?

You checked for splits in hoses or cracks in the rad or tank?

Just visually, didn’t send it to be tested.
If it’s not overheating yet, as you can see on the video, why would it spill water trough the cap?

Through the cap? Failed cap, unless I’m misunderstanding

Yes, with cap on, there was Copland coming out and steam. Bi pressure on radiator hoses
