There is one that is low-tox that is also green and I think Prestone is making a universal anti-freeze. The real issue is to keep a color so you can see it through testing devices. Mixing pink and green gets you a brownish that still works but looks like a rusty mix. I would stick with dexcool just because. Sold by various brands. They are almost all just Ethylene Glycol. Dexcool was some attempt by GM to promote a longer lasting coolant and they got in some trouble over that. The EG itself does not fade but the additives to protect against corrosion will break down. Either green or pink will work but I would stick with one or the other and carefully check the freeze protection # to what a 50/50 mix would provide which is -34F and it may take a few warm ups and cool downs to fully mix to get a dependable reading. Too much anti-freeze won't cool as well as the 50/50 mix so aim for that. Check this at radiator as the recovery tank could take a long time to fully mix in. Check the concentration again later to verify you are on target, T barbara New User May 29, 2007, 9:19 AM Post #3 of 4 (3284 views) Re: replacing radiator in 1997 oldsmobile bravada Sign In thanks tom and thank you for serving our country...sorry i missed it yesterday but hope your v-day was a good one. just got a call that the radiator was in and should delivered today...so will put dexcool back in and check the mixture as you recommended. nice cat... barbara Tom Greenleaf Ultimate Carjunky / Moderator May 29, 2007, 2:41 PM Post #4 of 4 (3281 views) Re: replacing radiator in 1997 oldsmobile bravada Sign In Just a note: I'm a veteran/moderator at this site.
