I've winterised many a block with the anti freeze muffs method. Drain completly,including the oil coolers,circulating pump hose,manifolds,block,water heatres if they have one. Run 4-5 gallons through--depending on you're systym,done. Never had an issue. I know,air don't freeze. Bondo is right on that respect. Neither does -100 coolant-blue. Some drain after the anti,but I don't just because I don't. Now the Bravo's we use a freshwater pump,as the pump on the motor when on the hard don't want to pull water or anti to well,the pump insures the anti is getting through the entire systym.
