Looking for some ideas. Recently my Ford Explorer started overheating. It's a 99 4.0L SOHC with 120,000 miles. Once it cooled down I checked the coolant and it looks a nice green although the overflow tank was blackish. I started the cold vehicle up without the radiator cap on. Once the temperature gauge made it about to the middle I started to get a good geyser which make me think that the thermostat opened and the water pump is working. When it gets hot turning on the heater drops the temp for a while. Am I missing something?
