I have a brand new radiator, but don’t want to use it and plug it up without giving it my best effort to clean out the rust and sediment out of my 216. I have the two side block plugs out and used a super magnet on a wire to fish out about a half of a cup of rust and chunks after digging around with a pic, the best I could. That only takes care of a couple of the cylinders. I have a couple of those doorman rubber plugs to put in at least temporarily while I try to clean out more. I have a Jerry rigged a 5 gallon bucket set up for a temporary radiator while I run the engine but my question is what should I put in to help dissolve and or remove things the best I can while it is running. The over the counter Prestone radiator flush? Or something stronger like vinegar mixture, etc? suggestions and opinions, please. Larry
