I have a 2003 Dodge Dakota V6, 2wd. After 2 to 2.5 hourh of constant 70+ mph interstate driving coolant starts discharging from the overflow tank outlet causing the vehicle to overheat. I have replaced the radiator, cap & thermostat. I have had the system pressure tested and no other leaks appear. There is no evidence of oil in the coolant or vice versa. What else could be wrong

Have it chemically tested to rule out a blown headgasket, cracked head or block
