This may sound crazy, but my indie says don't use the G-05 since it has acid in it that will damage aluminum (heads, etc.) Anyone hear of such a thing?

Me don't think he knows his antifreeze...................

He is confused...

Zerex G-05 is the original full chemistry in newer Ford & Daimler Chrysler vehicles. Its Hybrid Organic Acid Technology (HOAT) chemistry combines the best of conventional and organic acid-based chemistry to provide the ultimate protection against rust and corrosion.

For convenience and protection, try Zerex G-05 Ready To Use. Zerex G-05 Ready To Use combines the excellent temperature and corrosion protection of Zerex G-05 with de-mineralized water to help reduce the risk of cooling system deposits. The 50/50 mixture provides protection down to -34°F.

• Protection for up to 5 years / 150,000 miles
• Approved by Ford and DaimlerChrysler for use in automotive and diesel engines.
• Utilizes hybrid organic acid technology to minimize inhibitor depletion
• Low-silicate, low-pH and phosphate-free formula
• Provides protection against liner pitting and corrosion
• Helps prevent rust and corrosion
• Helps prevent hot weather boil-overs and cold weather freeze-ups
• Protects all cooling system metals, including aluminum

HOAT apears to have been first used sometime near 1984 and apears backward compatible to those before that, Diesels particularly it seems.

It is not. Propylene glycol pet safe varieties are available, but G-05 is not propylene glycol.

G-05 can be had from the chrysler dealer, ford dealer, pep boys or napa. From what ive seen, any of those stores are nearly as expensive, >$15.
