The engine is a Magnum 360 (5.9L). I just installed a new aluminium BeCool radiator. Is it possible that there was an air pocket in the radiator when I filled it after installing new? Before the new radiator the notest it got was 190', now it climbs to 210-212'.... the problem i'm having finding another thermostat is the flange dia. I need a 2.250" dia. and all i'm finding is 2.500" or smaller.
