White smoke is not good. It could be a blown head gasket or it could be a bad egr cooler which is common. You need a good truck shop to help as this repair is best done by someone expierenced in the 6. Diesels.
The proper coolant is critical in this motor as if you mix it or put the wrong coolant in, it will produce huge issues with the cooling system.
