I would not use DexCool or its equivalent in anything not specifically designed for it. Dex trashed a lot of vehicles before GM redesigned their cooling systems around it. Ford has done the same with their Specialty Orange. Gaskets, seals, and plastic components must be specifically compatible with Dex products.
There are plenty of long life products available that are compatible with your machine. I personally use Zerex G05 in almost every water cooled engine I own, but a lot of folks here use Fleet Charge I believe.
What others have posted is correct... if you do switch coolant types, make sure the cooling system is thoroughly flushed.
For the record, I barely caught one early GM DEXCOOL engine from damage and cleaned the horrible mess it left. My 2011 Ford was I believe the first model year to have their Specialty Orange (very similar to Dex), which was immediately flushed out when I got it. My point is that early on dex caused a lot of problems, and manufacturers redesigned the cooling systems to accommodate DexCool. A cooling system flat out not designed for DexCool is a catastrophe waiting to happen.
