Any help appreciated! Could an air lock have caused this?

Filled with water, bled and replaced rad cap. Have driven around and problem hasnt happened again so have drained and filled with coolant. Am just praying it doesnt happen again..

Just a Q regarding bleeding, according to the notes i have read, after filling you should run engine with rad cap off, and add coolant as needed. Issue i have is as soon as the t stat opens, all the coolant just starts comming out the radiator so i end up just putting the cap on and using the bleed screws.. Am having no heat issues now. Needle sits at a quarter highway, goes just above half in heavy traffic

I usually start bleeding with it cold with the heater off and holding the rpms at 2k until it gets to normal temp and the bubbles stop and then turn on the heater full blast and hold til 2k till the bubbles stop and repeat til i see no bubbles.
