Dexcool coolant have a shelf life??

[Afterimage]

I still have a half jug (about 2L) of Dexcool coolant (mixed with distilled water). It's been sitting on the shelf in my garage for like the last 5 years or so (when I did HCI on my C6 Z06).

Is that coolant still good or should I get a new jug and mix that coolant?

Once the weather gets warmer I will be doing my CAC bleed procedure with my cooler bleeder that I purchased back in January, just want to make sure I can still use the coolant I have for the procedure.

DexCool supposedly has a shelf life of 8 + years.
