Re: Serpentine setups..info please
Single belt design does not really gain efficiency unless you do like pcmcobra above and loose the clutch fan. I gained at least 1 MPG with electric fans on my 91 truck (it already has a serpentine setup). The looks do improve over the older style belt systems and there is more aftermarket goodies for the serpentine setup designs. However the setback is: a broken belt and you don't go anywhere PERIOD.
