So i know its a beat to death subject, but i just have a weird question i couldn't seem to find with a quick search. Long story short i have the coolant expansion tank combos coming in the mail this week and i went out to my car to figure out what coolant i had so i can search for a proper replacement. This is where my question comes in. In my intercooler tank i have the gold coolant, and in the other tank i have the green coolant?? Is this bad, aren't they supposed to be the same, and what should i replace them with because i will be draining both?
