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?

The dye color can fade, but so long as the bottle is sealed, there's no way for the antifreezing components (ethanol and/or PEG) to escape. I wouldn't have any qualms about using year-old discolored antifreeze, assuming of course it doesn't seem like there's something slimy growing in it or it's otherwise obviously bad and not merely faded.
I have a year-old bottle of RV antifreeze and its color didn't fade, so I don't think I'd use a bottle if it did fade given the expensive consequences if it doesn't work as expected.
