Dexcool is pink and most others are green. 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,

Just a note: I'm a veteran/moderator at this site. I'm thankful for our veterans in armed services but that's not what that means in this case. It's really a designation that says I've made too many posts hereSmile Kitty says 'HI"
