Any normal antifreeze, Zerex, Prestone, store brands will be fine on a 6.9 and 7.3L IDI engine, the ADDITIVE is what is important. My Ford store sells Fleetrite brand, not the expensive stuff in Ford bottles. FLEET-RITE DCA ( diesel coolant additive) is fine, it's a bright blue color, same stuff in the Ford bottle, there's instructions on the bottle how much to add. My Powerstroke held 32 quarts, think I used 4 or 5 bottles of DCA on a drain & flush. I bought a bottle of FLEETRITE test strips too. Check coolant every oil change, flush & refill every 100,000 miles. I have no experience with DCA-2 Pink?

And anywhere you see the inside of the cooling system everything looks completely clean, like when SON put a new water pump on my old truck a year ago. Thats TWO waterpumps on it now. Factory pump replaced at 128,000 miles, last year's around 310,000 miles.

As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
