Antifreeze no longer pink
I'm about to winterize my rig. I go to two of the gallons of antifreeze I've had since last last year. Unopened, but the pink colour is gone. Is this stuff still okay to use?

I have had some sitting outside for over two years and it's still pink, was the seal broke under the cap when you opened it? If so it may have been used & refilled with water.
