I went through the same routine on my 7.5 Onan. Mine ended up being a partially clogged Onan radiatior. I took it out myself (not a simple job), and took it to a radiator shop that took the tanks off and boiled/rodded the radiator core. There was white mineral deposits clogging up some of the tubes. This complete radiator service solved the problem.
