Has anyone on here done an efan swap? I have a 2000 silverado with the clutch fan, hate the sound and want to switch. Hoping someone could point me in the direction of what i need and a guide on how to do the swap. I know i need to get a tune to have the pcm turn the fans on and off when needed, ill need the harness. I'd like to do OEM, so does this mean LS1 fans? Im pretty much a noob at knowin what i'm going to need for the swap. I just want OEM efans. Hate the sound of the clutch fan and wouldnt mind the tiny hp's freed up and the noise gone + tiny mpg increase.
