I believe the heater core is the root cause of my truck slowly getting hot at idle with the A/C on. Running an 8.1, stock aux. fan plus second aux. fan. Heater is plumbed like stock, which dumps heater core return to cold side of radiator. Truck has factory high cap. radiator (same size as diesel rad.)
