Let me clarify that at ram air the mechanical gauge cools down to within 5 degrees of the Fitech but at idle it climbs. I have a secondary fan with probe in the rad set at 190 and it never comes on until Fitech sensor hits about 190+/-. Prior to rebuild the mech. gauge would run up to 200+/- and settle down to 180/185 after t-stat opened. Now it goes to 215 at idle and climbs until primary fan kicks on at 180 and it will stay at 210-215. All temps shot with infrared.
