In 17 years I have never worried about the additive, just change the coolant on time with the right spec. Keep an eye on the plastic coolant recovery tank. I had to replace mine when it started to leak
I had the front end rebuilt at 160,000 miles with all Moog parts with grease fittings. She is tight now. It may take a few hundred miles to break in the front end. There can be memory steering for awhile.
Interesting. I've always used either the FoMoCo additive or DCA 4, not because of cavitation issues but because it keeps the cooling system clean.
I did the king pin (I have a 350 4x4), with a Dana 609 full floating front axle. at 45K miles and canned the cheapo Ford junk. Moog for me too with zerks which get greased every oil change.
I may forego the additive and just put a pre-charged coolant filter on next time.
My 97 has less than 80K total miles on it and has never seen a Michigan winter. It sleeps in a heated garage all winter. Everyone wants to buy it, not for sale.
