Corvair's were air cooled back in the 60's. I think maybe Volkswagons are also. Could be a few others.
No offense, but I think my first experience with this was in 1964 I was about 6 years old, riding with Mom in her Chrysler 383 station wagon in a blizzard, and it overheated. We hit the next service station, they parked it in the bay for a couple hours, filled it up, and off we went. I learned the lesson of antifreeze early on. Otherwise we could just use water all year.

woooo weee I don't go back that far by a long shot but you're definitely right about air cooling. Liquid cooled engines are not designed to be primarily cooled by outside temps. If you do not have coolant flow/circulating throughout the coolant jackets, your engine will overheat.

Come on now I'm not quite over the hill yet sonny boy. But for that matter, and not to sound like a redneck because I was anything but, but how some of these kids "nowaday" ever grew up without replacing an engine or two from a come along on a tree branch in the front yard, well, they just missed part of growing up right in America, far as I'm concerned.

Well, I've never personally needed to replace an engine that way but I get where you're coming from. Each generation gets softer and softer.

Well honestly I pulled a buick v6 that way and did the engine bearings once, at my brothers. A year later the 'rebuilt crankshaft' (turned down, welded back up to spec) that the machine shop sold me snapped in half getting off the highway in Utica NY.
Next gen of guys are pretty good some of them. It's the level of complexity in the newer vehicles that prevents most from doing their own work now. Maybe.
