How does the hydraulic fan work?

[Barwick]

I'm about to pick up my '00 LS V8 Sport today, and I keep hearing about issues with the cooling fans going out, and it costing like $500 for the part and 10 hours labor... I'm wondering, what the HECK kinda fan is that? Is it a fan that is powered by hydraulic fluid lines running to it? Or is it a fan on a hydraulic clutch (like RX-7's I worked on before) attached to the engine and speeds up/slows down as the fluid inside it gets hotter or cooler?

It has hydraulic lines running to it and it's own hydraulic pump driven by the fan belt.

Couldnt you just hook up an electric fan and run it to a switch or acc power?

Hey go to fordpartsnet.com and it's only $285.00 just a heads up. The installed at a dealer was $200.00, had it done about a month ago.
