Had radiator replaced on mine was leaking these radiators are not cheap. Then the fan clutch stopped working. Replaced it myself with a hayden 2799 severe duty fan clutch. Someone said on here 4 hour job not on mine call that BS. I doubt its the t stat not really that cheap if you want a good one. 190 degree stat
Mine would run around the l on normal now runs up there half way or under. Keep telling the ford dealer it was the fan clutch they only wanted to do a dye test and was talking head job pulled it out and changed the fan clutch myself.
