Bob, you got me looking when you mentioned the Dexcool and Zerex G05 coolants. You caution the use of organic acid types, yet it appears the Zerex is that type, per the following blurb on its site: "Utilizes hybrid organic acid technology to minimize inhibitor depletion" Query, do all green coolants contain high silicate content? I have used generic Autozone and/or Napa green coolants for 15 years on my '88 9KT, draining/filling it yearly, always using distilled water, and water pump lube, w/o incident, though I have had to replace the water pump twice (the last time being this year).
