I get my anti freeze form the junk yard. they filter the antifreeze and test it with a hydrometer and sell it for $1 a gallon. never had a problem. the tempurature here in the last 15 years went from a low of -27f to a high of 113f

Nice work on that post for the year 2000 but I'm staying with Prestone Long Life on my '97 Bravada.

Recycled coolant at $1 a gal. is an interesting idea. If normal new coolant pH and alkalinity were known and the recycled stuff was fixed for the corrosion potential, I wonder what other considerations would need to be looked at? Gaskets?

I converted to the standard green and with stick with it. I'm not a fan of Dex-cool. This TSB does mention the leak stop that you were talking about. How do they know it causes problems if they didn't try? :)

my 92 was converted to the green stuff before i bought it. we had a small heater core leak that went unnoticed until we went on a long road trip. about three hours into the trip my wife, who was sitting in the passanger seat with the windows rolled up, had a gran mal seizure. very scary. and she has a cdl so she automaticaly lost her job for 6 months and can't even drive any vehicle for 6 months.

common anti-freeze is a veritable soup of toxic chemicals, although up to now i've never experienced any problems even though i've changed three cores and a couple of radiator hoses in the past two years on my vehicles. we think it was the duration of exposure combined with lack of ventilation, or worse her sole source of ventilation was thru the leaking core. The link to a poison center sheet on one of the worst componets of anti-freeze is http://www.iowapoison.com/index.asp?pageID=155

i am just now doing a google on the non toxic anti-freezes such as sierra, does anyone have any experience with these. let me know

I'm sorry pal, that looks like some pretty serious stuff. The link to the Iowa Poision Center was very imformative and the reactions looked pretty scarey.
I don't know about the alternative antifreeze's but I'll start checking the labels when I go to the parts store.
I hope your wife fully recovers from this very soon.
