Default Re: fun day with un expected bonus

i just used an industrial hot water pressure washer with chemical degreaser to clean a stock round tube 29 radiator,its amazing what backflushing will do,most radiator debris is a combination of rust and water pump grease,the hot water and chemical does the job. Original Ford radiators are remarkably heavier and more robust than some of the cheap reproductions out there,the funnel type top neck aides in thermosiphon water flow too,your biggest issue is fin separation from the tube,if you have alot of that you're done,its critical that the fin contacts the tube for heat transfer
