Hi Tanman, the clue is in the subject of the post "Wanted listeroid in Alaska". I have been to Canada in winter with temperatures down to minus 40 centigrade, I am guessing things are only going to get colder the further north you go. If Rbodell is serious about running a water cooled engine he is going to have to do it indoors or run it 24/7, alternatively he could put it on some sort of heated life support with a lot of antifreeze.
