Re: Heavy Towing: Electric fans or clutch fan?
Hello Aruba1. I hope all is well with your LSx Swap. I don't know of this means anything to you but in my 1971 c10, my pcm was programmed with the fan #1 to turn on at 195 degrees and fan #2 at 205. In Miami, Florida heat, my fans rarely rarely came on in stop and go traffic. LSx can run hotter temps. They are not your regular SBC or BBC.
