Hi Scotty, I’m having an issue where my coolant will flow into my overflow then leak completely out not back into the radiator. What could it be?

many things can do that, but it has to be one of these https://www.youtube.com/watch?v=evpaTW2WJ5Y

I stayed up all night. Switched the thermostat, and radiator cap. Did a coolant flush now it’s good. Thank you!
