Where can I get some closed cooling system coolant to top off the reservoirs?
North of tampa. Most marine stores here have no clue what I'm talking about.
Is that RV coolant stuff the same?
ok.. RV stuff antifreeze only. and ? is the Dex cool 50/50 or something? Can't I just add regular antifreeze to top off?
I really don't know whats in it, but I don't want to add something I can't.
