Does coolant expire or not?

[imcool]

I have Triumph OEM coolant sitting in my garage (not weather controlled) for last 3 years

should I use it or not?

Use it, after its in bike, change it often, it does kinda cake up, im currently running water wetter and distilled water for spring summer and will trash this winter.

Unopened it should be good.
