Keeping my 273 commando cooler during these record hot temperatures

Recognizing from experience that Mopars always tend to run a bit on the hotter side, but also realizing we are experiencing record heat, especially here in Florida… Any thoughts on using coolant additives or non-water coolant to help keep the engine temperature down? Haven’t yet overheated this summer, but been close. Appreciate any thoughts and advice! I already have a high-performance dual electric fan, which has helped a lot.
