Bought some Coolant today, couldn't see the colour from the outside and it turns out to be red (like my face). I'm right in thinking you shouldn't use this in Scoobies aren't I?

At the moment the reservoir looks to be blue although it's very low so hard to tell and green when I take the radiator cap off. Will Blue or Green suffice - what's the difference??

 

u can get anti frezze in any colour u like its just a die thay add 2 it but i have been told u can mix a certain red atnifrezze with any other colour but dunno if thast a certain make or type it should say on the bottle of u acn mix it with others anyway
