318is M44 engine issue.

Blew the plastic 'Y' fitting off the back of the head and blew the top hose off the Radiator, Engine got hot but didn't get up to overheating mode, Radiator still full of fluid, Suspecting a bad water pump, If it was a head gasket it would be bubbling all the time, This is periodic as the video shows and the heater doesnt work either, What do you think????

You can get the kit that tests for gases in the coolant to make sure it is the head gasket before tearing it down. That said if you don't know the condition of the cooling system you should do the whole thing. It's relatively cheap and good to do before catastrophic failure.
