I just read from the product description that the G-05 is an HOAT.

This gives me cause for concern.
I don't think any
of my Prestone stuff is HOAT. IIt's probably mostly the IAT old school Ethylene Glycol stuff. I gave @97K15004WD
right around 600lbs I would guesstimate a solid 550 and possibly more of my Antifreeze stash (still have about half remaining) and aside from SOME of the Extended Life 150,000 mile stuff (the yellowish/green, color not advertised on bottle.. says it mixes with anything) and maybe SOME specific POAT coolant that I've always been afraid to mix, because it has always been aaid doing so can eat head gaskets of coolants of different types.. MOST of what I have is straight up Autozone Universal Yellow (is yellow, says it is yellow, says it mixes with anything.) Followed by plain, old school Green EG coolant. Which I now wonder what cars you can actually use the old green EG in.
So now I'm questioning if I did anything wrong by starting a partial exchange of the Autozone Universal Yellow. It DOES say it mixes with anything.
There was a statement made.. "You cannot go by the color" some thread in Antifreeze subforum.
So then. Point of all this.. IF I find the Zerex G-05 (would look in Walmart first then look online, more than likely. A sure-fire way to not overpay) .. I would then arrange to have the system flushed, since while the coolant looks CLEANER now that I've done a partial exchange of about 3 quarts, twice I believe (some say partial drain and fills are fine) . https://bobistheoilguy.com/forums/threads/any-partial-coolant-drain-advocates.324279/
- what I'm doing is somewhere between Post #4 where @PandaBear
says he drains and fills the overflow tank every 6 months or so, which is basically what I did twice in two weeks, and more than that.
Aside from possibly introducing a flush into the system and to keep doing that, if I'm on the wrong track with the Universal, I can stop. The system would need to be flushed before going full G-05. So now I will look for the system capacity of the G-05.
Apparently it holds 11.6 quarts so basicly 3 gallons. So I've replaced approximately 1/3 of it. Think any damage occurred?
