Radiator Fans: (pun intended) This is a steam radiator, (no cross flow passage or fittings on top) Fittings are on the bottom, one on each side depending on the application. I have another like this with 4 more fins and 80 years worth of paint. I also have a plain jane hot water radiator, not as sexy, which I’ll probably use on the genset. Its about the same size as a window fan and will be used to heat the garage. No pump just thermo. I want to use the hot water for the house but have to figure a good way to do it. The generator location is incompatible with below zero temperatures and pure water in the lines without spending big bucks, which will (at this time) take too many years to recover. All of the radiators were free from my brother who has restored an old house. I have to sell one that I’ve fixed up and give him the $.
Joe: No timing marks found. I jury rigged a dial indicator today and will see how close I got when I borrow a real one.
Guy, its not powder coated but it is painted black.

If you wanted to use a steam radiator like the one in the pic I think you could just fill it up about 1/2 way with antifreeze, put your hot in and cold out on oppisite sides of the bottom and just tilt it a couple inches toward the cold side. They shed a lot of heat but I'd keep an eye on it when its hot out.
Thank You, Geno
