need some fan info please

Sorry it is on my 67 valiant with the slant 6. i tend to forget that not everyone know what i have. lol. when i got her she had a large aftermarket radiator with the lower outlet on the wrong side. and an electric fan assembly as well. but i have been running into an issue of the battery trying to go dead while i am driving with the radio on. so i am going back to the factory radiator and fan.
