Hey all, hope everyone is doing OK? I still can't believe I got Bobcat as my username! Who would have thunk it?? I just purchased a 763G Model and was wondering what is the easiest way to drain and flush the cooling system. I'm replacing all fluids and filters. This will give me an opportunity to get a good look at her before winter sets in. Here in Alaska it can get dam cold and I want to be ready. Later Scott.
