2000 LS gen1 overheats fan never kicks on. I can spin fan by hand with some resistance. I have searched forum and net for hours. Have not located anything similar.

Hydraulic fan does not kick on.

Plus I have no coolant coming from bleed out valve when trying to bleed cooling system. Water pump?
Your best bet is to convert to an electric fan. The hydraulic versions were troublesome and are obsolete. It was a bad idea from the beginning that came from Jaguar.
Several threads on the forum on how to do it.
Next all the plastic in the cooling system is full of micro cracks because of time and heat. These parts are hard to find now. Have you pressure tested the cooling system when cold?

"Hydraulic fans a bad idea"
I wouldn't go that far. It's mostly just lazy mechanics that gave them a bad name. It should be noted that hydraulic fans were used by Jeep which also fell to lazy mechanics, and Toyota on some Camry's which for some reason you never hear about. Odd, that. But anyway, the system is real simple. Pump, fan "motor", and a pcm-controlled solenoid that bleeds off pump pressure to the to the inlet of the pump. If the solenoid weren't there the fan would run 100 percent all the time. As it is, the solenoid is default open so there's no pressure to run the fan and the pcm runs the solenoid cycle up (to close it more) and the fluid once bypassed goes to the fan. Easy enough.
Problem now is that solenoids are obsolete by everybody so no new units available if that's the problem. Thing is, you'd need somebody to diagnose if it's the solenoid, the wiring, the pcm, or something else. There's no quick way out for the average owner.

Thank you. I read through the forum and did not see this particular problem and still got called out for as a dumb ass. I appreciate the information. I may sell the thing I dont need a project. I know it's only time and around 1000 to get it right but... I'd rather buy an old vw bug to work on or a square body chevy."Hydraulic fans a bad idea"
