Question by whit: What is the difference between orange and green antifreeze?
I have a 1998 Chevy s10 pickup and i noticed the antifreeze was low so we put regular green antifreeze in and when we opened the radiator cap the antifreeze in there was orange. I know that orange is used in gm vehicles but what is the difference and was it bad that i mixed the green coolant with the orange.

I don’t think it makes a difference, but the orange color might also be an indication of rust… I would check and make sure the mixture in your radiator is 50/50, they sell a silly little tool for doing just that, so long it’s 50/50 then you should be ok.
You should be able to get an antifreeze mix tester at most any auto parts store, it has a small rubber hose and a clear plastic part with a gauge and a primer bulb, cost is like $ 10′ish or so.
