Engine fan

Correct, Rusty- the Magnum pumps spin opposite of the LAs because of the serpentine drive. Besides, the Manum fans thread directly onto the pump shaft, and do not bolt to a flange like the LAs.
I thought that was the case as well. I knew some threaded onto the water pump, but I didn't know all did. When it starts gettin to this later model stuff, I'm not as sharp. I try to limit myself to old stuff......like me. lol
