6.7 Powerstroke Coolant hose O ring cheap easy fix

[@danieldavis8299]

Did you have to drain coolant? I need to do this as well but I don’t know if I need to drain the coolant or if I can just pop off the fitting and replace the o ring.

Nope you’ll loose some just have a catcher ready definitely buy At least another gallon though. No need to drain it all though good luck with your repair!
