Using this on a Ford 6.0L Diesel after absolute cleansing with chemical based cooling flush. Never mix your coolants and never use a silicant based coolant in the 6.0L. Silicant based coolant will drop out and clog the oil cooler with a slime/sludge that will eventually lead to oil cooler and EGR cooler failure, possible engine failure. Flush the coolant system with passion and use this Antifreeze.
