I am having a problem with my motor climbing to over 180 deg when climbing out. once I level out it falls back below 180 with reduced powerI It is a type 4 witrh a 582 with a standard rad under the floor.I did not have this problem until the temp rose to the 90 deg. I read the threads with little help.I first reset the prop to 6200 st while tied to a tree .The ex pipe was short and seemed to exit right in front of the rad so it was extended several inches .I also drained and removed the lines and rad to be sure they were clear.When refilling the rad I used 50-50 mix and added
the super colling additive that is supposed to drop the temp about 10 deg.I got no results.I checked the water pump for any damage and looked to see if I had a thermostat..by now I am running out of ideas so I built another rad from a new heater core from a ford and mounted it in line with the lower rad .It was mounted just in front of the carbs.the lines run from the pump to it and then on down to the old rad.None of this helped at all.I didnt mess with the carbs because the motor has about 80 hrs and I hear that if you have to rejet veryfar from stock something is wrong elsewhere.Can any one give me any tips on what to try next.
