Your not supposed to mix different types of coolants so as long as you drained it all and filled back up with only that stuff then you should be fine.The green is ethylene glycol and the orange is propylene glycol, I think. They are different formulas and can't be mixed.

The Prestone Dex cool is orange and it says on the jug Contains ethylene glycol in the warning label

Hmm, well I know they told me never to go by color either. As long as it is the same type as before is all that matters.

I would recommend draining and flushing the system.:2cents: I have changed several GM cars and trucks over to good old green antifreeze due to DEXCOOL eating away at gaskets and seals in the cooling system. Have had to replace both intake gaskets and head gaskets from the DEXCOOL. Seems to be worse on compnents if the vehicle isn't driven very much.
