I need to top off the coolant in a 2018 Buick Encore. The OM just says to use “Dexcool” coolant. I have a jug of Prestone brand Dexcool that is probably from 2008-2010 or so (left over from back in the day when I drove a Saturn that took Dexcool) that I’d like to use if it is the correct stuff. Is this okay to use?
Thanks.
Thanks.
