Cool Lincoln Fan

Thanks to all for recommending the Lincoln fan.

I got one from E-Brake for about $70 with shipping. Dirty as hell, but I cleaned her up. The controller I am getting seems pretty low budget, with a radiator sensor that turns on at 180. I hope this cools the stocker 350 with the new 4-core.

Another problem is that the temp gauge is reading 240 while running down the road cool. The guage is good, but I think the new motor's sending unit (which was *supposed to be new*) is whacked. I'm thinking about a couple of mechanical guages.

The question is, now, what is the middle wire on the connection to the fan supposed to do?

I know I'm lame. But I *do* know + (Brn/White) and - (Black). But the Blue center wire? I don't have the loom for the thermo-coupling (or whatever you call it....to look at yet. But I figured I'd ask so I don't trip over myself when it comes and I try the install.

Also, in another seriously lame question: It seems logical to me that when removing the fan and fan clutch, I'll need shorter bolts for the pulley. Anybody know the lenth of the bolts I'll need? I ask, because the truck has been returned to the motor installer to chase an oil leak (he thinks it's the oil sending unit), so I can't just go out and measure.

Finally, should I worry about the alternator output with this set up? How do I know what output my new alt is pushing. I didn't buy iyt. And the paperwork from the Previous Owner just shows the new purchase price and no alt. model no. or any other data.

Thanks, All.
