Ah Crap! Green Coolant! I had my car at the shop a few months ago. I don't drive it very often, so I haven't been crawling around in it much. The other day I was going to take it for a cruise. I opened the radiator cap and saw GREEN COOLANT!!! 
Apparently the "race shop" has never heard of dex-cool. I am going to flush it, but I'm just curious as to whether or not the green coolant damaged anything. Any ideas?

I've been using the prestone that will mix with either one and it's green. I agree that Dexcool tends to gum some things up (like my overflow, looks like it's full of mud, the cooling system looks new inside, it seems to oxidize when it mixes with air and turn to goop).
The green stuff is fine. They had aluminum blocks/radiators long before Dexcool and the world did just fine. I wouldn't run out and change it.

Most all modern green coolants are aluminum compatible. The only thing Dexcool may have over them is some extension of useful life. I do my coolants every two years anyway, so it doesn't matter.

NO Modern GREEN coolant is safe for ALUMINUM...Read the labels..the ORANGE is fine....maybe some sponsor can speak up...Nothing wrong with Dexcool..just don't leave it in for years.

What about GREEN extended life coolant. Green coolant is perfectly acceptable in your car as long as they did not mix the two coolants together. How many miles are on your car? I would not reccommend replacing the coolant in a vehicle with over 60,000 miles because they are different chemical make ups and the seals are broke in for whatever has been there to that point.
i agree, i work at a shop where we have green coolant that will mix with dexcool. go back to the shop and talk to them about it
