I have three gallons of GM dex cool that where never opened. Their at least 3 years old.
Would it be safe to use?
Thanks

You should absolutely NOT use them. Send me a PM, I'll give you my address and you can UPS them to me. Free, of course. I have a small fleet of GM vehicles using Dexcool which I change every 5 years whether they need it or not. If some old lady T-bones the car, I won't need to change anymore.

Edit: I have 3 gallons of Prestone Dexcool in my garage currently; 2 unopened. Just went to see if I could find a DATE anywhere on the containers, all I can find is "copyright 2019" on logo on back. If I were in your shoes, I would use what you have without a moments hesitation. Unless you really WANT to send them to me...

Not a problem. I’ve used stuff 5 years old, left over from the last change.

Even if it were opened, I would still use it.
