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 think this is the best option.
  • If you run RV antifreeze thru a Water filter, it will remove the Pink. Still good, just does not have the color. But, I have Pink antifreeze at the shop more than 3 years old and is still pink. Doug
  • Antifreeze is cheap. Replace it and try some new.
  • 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.
  • I have had a bottle sitting around for over a year and its still pink. Option 1 call the company Option 2 go buy new stuff. Is the cost of good antifreeze worth the possible destruction freezing could do in your rig.
