Engine coolant is low..
 

Engine coolant is low in over flow container .. wanted to add some fluid in there to get it back to min level. Went to autozone bought some g05 noticed when I got home it's green and not pink like the current fluid in the overflow tank. Going to order OEM fluid off Amazon, was reading in the comment section that it's freakin orange and not pink!? lol I'm sorry I'm a complete noob, was the fluid orange in my truck from factory and turned to the pink color from use!!? Obviously want to order the right stuff this time so I'm not sitting on a bottle of unusable coolant like I currently am with the green stuff.. THANK YOU IN ADVANCE

What year? They went from orange to a more purple fluid over the years. I don't know how compatible they are, but it is a well known fact the older green type is not and if you mixed it with the orange stuff it bad things can happen. They react and gel up.
