92 2wd 4.9L
well getting a truck for my g/f 800 bucks it has a small hole in the rad. 209 on the dash 110K on the motor needs a starter also clean other wise.
the only thing i know about these 4.9's is they are going to be around long after the world ends. past that i dont know much ha.
it needs a fan clutch too but im thinking of getting her an E-fan and after looking at the truck yesterday i relized theres not much room in there for an e-fan what do yall with the 4.9L use for a fan set up?
ill post some pictures on sat when we get the truck.

Converting energy from one form to another invariably wastes some of it (which is why a perpetual motion machine is impossible, and why superconductors are so valuable); most coversions are on the order of 50% lost, or more, usually as heat or noise. Either type of fan takes energy from the drivebelt, but the e-fan converts it from mechanical to electrical in the alternator (losing a LOT of heat), then pulls that electricity through wires & connectors with resistance (more heat), then converts it BACK to mechanical in the fan motor. A mech fan simply drives the fan directly off the belt - virtually no loss (by comparison). And that only happens when the clutch is engaged.
An e-fan requires complicated integration with the rest of the vehicle before it even approaches that efficiency, and these old trucks aren't built for it. You'd have to install a newer PCM that was designed for an e-fan.

i slaped an E-fan on my 97 and i rarely turn it on only if im sitting in traffic for a long time my clutch fan was always roaring and loud. not to mention i picked up 2 more MPG's going to an E-fan
you dont need a PCM to run an E-fan mine is done with a simple 12volt switch.
E-fans at my local junk yard are 30 bucks for any fan set up.

You can run an e-fan with a simple system, but it won't be nearly as efficient as a cheap clutch. The e-fans on MY truck are wired up with several switches & relays, but I didn't do it for MPG; I did it because my clutch went bad, and I had the e-fans/relays/switches/wiring in my junkpile, so it cost me less than buying a new clutch. And I do a lot of off-roading, so it's nice to be able to turn the fans off before fording.
