ThanksDexcool is pink, but that doesn't explain the green stuff, some are compatible with others, others are not. Check owners manual or decal on generator for info.
The color you see on the outside is the same color when I take off the cap and look inside.7.3 ECD takes a 50/50 mix of ethylene glycol and water. The off color is likely due to a faded bottle. If not, do a complete flush and change the anode.
I am sure it came new with Dex Cool which is a red/orange color. That looks like Prestone. I have read the horror stories of mixing the two, but have no experience. I would go back with Prestone and not take a chance of mixing.
