I Have Replaced The Thermostat Twice And Running It With Out Antifreez. What The Problem Is That It Does Not Over Heat As Long As I Drive 55-60 But when I Get Over That It Will Over Heat Very Fast. I Can't Figure This One Out. Do You Have Any Ideas As To What Will Fix This Problem ? Grateful For Any Help. Richard Whitman.

You should never run straight water. If it's overheating only at higher speeds, suspected are the radiator not doing it's job or a blown head gasket from previous overheating.
