Need thermostatic controller for hydraulic fan on Eagle

[JackConrad]

     i've got a thermostatic controller for my hydraulic engine fan that was spraying oil, so we tied it off and the fan runs full speed.  i want to get a new hydralic thermostatic controller put it before it gets cold so that itdoesn't run full speed when it shouldn't.  suggestions on parts yards that might have one, or a method of repairing.  if you know what it looks like, the hydraulic half seem to have come loose from the sensor section that bolts into the coolant pipes.  if you don't hold it together, oil squirts out.  if this should go onto a separate post, someone just tell me and i'll start a new question. or just send an answer to my email.
thanks

I moved this to a new topic so will get more attention.  Jack

As of 4 months back Norris at Jefferson Truck and Bus said he had a couple of model numbers in stock. My valve is a little sticky too but I have not bought and replaced the piece yet. I took mine apart and cleaned it up and then installed a solenoid in the circuit so I can fip a switch and get full fan output no matter what. Nice feature for going up the big bumps.
