is zerex G-05 okay to use in 7.3? I searched forum but couldn't find anything, back says okay for heavy duty applications in navistar and ford, do I need to add the sca to this stuff? It's red in color and is supposed to be a good brand coolant for diesels, some mentioned adding a coolent filter and that they come pre charged with them? Are they expensive? Easy to instal?
