I've got an 06 6.0 that overheats. I have had tons of input from diesel techs and backyard mechanics and nothing is really helping! I've heard everything from cracked head to thermostat issues. I am also wondering if you have to pull the cab if cracked heads are the issue. I heard that cab pulling is only on the 08 6.4 and I've also heard that its on the 6.0's too. My truck isn't really showing signs of a cracked head. There is no fuel in the coolant. No oil in the coolant. No coolant in the oil. It just gets really hot after a few miles of driving. Its got the EGR delete. Does anyone know of anything else it could be before I take it to a shop and get taken for a ride? thank you!!!!
