My 99 4.7 has been slowly getting hotter and hotter during periods of long idle, while warm, and running AC. The ECT will stay in good range during driving but once i hit traffic or a long stop my ect will climb and then drop to normal once i contribute driving. My temp stays between 201-206 during normal driving. Thinking maybe fan clutch? Or is there something else i should be looking for, i have a new radiator and thermostat/housing already in since those had previously failed. Any help is appreciated! Thank you
