    Hey mate, these 4.7s are a little different. The coolant is recirculated behind the tstat and it only allows a percentage of coolant to come from the radiator. Make sure the system is clear in the waterjacket. Might be time to flush it good. Also make sure the electric fan comes on at 195 and that the clutch in the mechanical fan is working. I suspect it is not. Better replace that.
