'Getting little heat inside my 91 350 SDL. Fan runs normally. Symptoms found thus far with ambient temp ~45F: At 60mph cruise, eng temp = 70C, After stopping and accelerating briskly, temp goes to ~ 79C, then back to 70C at cruise. After stopping and turning eng off, heater immediately blows warm/hot air for minute or so after restarting, then back to cool. Tstat? Monovalve? ACC? Tips? TIA
BTW, 'just reviewed recent archives. Wilton
