The other day, I was checking fluid levels and eyeballing everything in my engine compartment, and I noticed something that somehow I had never noticed before. I have electric fans! Is this something that came from the factory? I bought the truck used, so it may have been added by the previous owner, but it sure looked like a factory installation. I have read many posts where people suggest electric fans as a modification, but wasn't sure if it was a factory option as well. Just curious.
