In addition to the Moyer A-4 Manual, I also have a copy of the "Service and Repair Manual for Atomic 4 Marine Engine." This manual, in many ways, is a lot like Don's manual. It was written by Robert Staton and was published in Canada in the '80's and '90's. In Staton's book under "Winterization" he states that to properly winterize the cooling system, one needs to only remove the three drain plugs in the block and manifold and then loosen the water pump cover plate to drain the cooling system. (He also mentions all the other stuff like oil changes, fogging the cylinders, fuel treatments, etc). Now being printed in Toronto by people who know a little about cool weather, I was intrigued by this very simple method of prepping for winter. I've read extensively on the forum about anti-freeze, thermostat removing, and pinching off by-pass hoses to prep our engines for cold weather. This method seems so straighforward, I'm wondering about the drawbacks.
My question is this: What is wrong with the way Staton recommends to drain the engine? Does anyone here winterize their engine (in cold climates especially) this way?
