97 4.6...green or that orange-ish stuff????

 

Go with the green, it even mixes with the orange.

 

To make brown!!

sry

 

i thought the orange was long life or aluminum friendly or sumthin weird. i thought you were never sposed to mix them.

 

I always go with green. I figure orange is a different color, therefore different is scary. ha ha. i dont think it really matters.

 

I would not mix them. there are certain brands that say they can mix but not all of them mix properly. GM has had a lot of trouble with their orange coolant so I always go with the green. I get uneasy about driving 100,000 miles with the same coolant anyways.
