Fan swap questions?

On the GC ZJ, I have read several post and articles of people swapping out the clutch fan for a fan out of a ford 3.8 Taurus which the fan mounts on the radiator clips and only needs little mod to fit. This is a 2 speed fan. What I am not understanding is this.

They say the fan draws 40 amps. Thats a lot of juice. I have seen fans that claim to push 2800 cfm and only draw 14 amps. How can this fan draw so much?

Also wouldn't you kill your electrical system if you ran aux lights, fan, stereo and headlights all at once?

Has anyone done this in the hotter climates in the west? I live in the phoenix area, I am thinking about this, but want to make sure it is a good idea.

Thanks.
Tim

Yeah a lot of people have done this swap with good results, but it does draw a lot of amps. From what I read, the fan will draw 90-100 amps at startup and then around 30-40 continous draw. You'll have to have some high amp relays put in place as well. If your running extra lights, stereo, etc, you'll need to get a good high amp alternator and good battery as well.
These fans can be found dirt cheap at junk yards but you just have to figure in for the extra wiring, high amp relays, alt, etc.

Yeah, I think a relay with adequate wiring would be OK. I'm sure a Taurus doesn't have a killer electrical system. Check the wire gauge and fuse rating on the Taurus when you get the fan.
