i did the electric fans on my 03 gmc, and you do notice a small power increase off the line, i had 2, 16" pro comps cost 25 each, the relays, switches and wiring cost another 30, and they wanted a 160 for a new clutch fan. f that!

this was the 3 rd clutch fan and the warranty ran out.

the truck ran 1 deg cooler, and the a/c blew ice cold like never before, and i gained maybe 2 mpg, if i drove it nice.

have fun with Frankenstein, when trucks were still trucks.
