So...to continue irritatine you all.... <just kidding> here's a pic of the fan and shroud. The shroud is a full back side cover so the fan has to pull thru the entire radiator... Block flush is next then back together for testing... Still hot enough here...maybe 96...to get a good test. The relay is settable to any temp you choose.
