I’m looking to change the coolant on my 2017 1.5L EcoBoost engine. When I first drained it, I was only able to get about 1 gal out (about 1/3 the total liquid in the system) using the radiator drain plug. I would like to be able to drain everything so that way I won’t have to guess when it comes to adding coolant concentrate to get the right ratio. Does anyone know of an easy way to completely drain the cooling system?
