Looking for some instructions to replace a 6.7L head gasket.
Do I need any special tools.

Underload condition, Blowing water/coolant from the overflow tank.

Just talked to my buddy. They found the EGR cooler to be causing the problem. Seems it was allowing exhaust gas into the cooling system and blowing it out the overflow tank. So far with a EGR and EGR cooler delete, every things working normal.
