i've got a 91 model 15 with the hydraulic fans.  i replaced the pump a few months ago, but now i'm concerned about how i connected everything.  fortunately eagle was smart enough to make the fans run fast  with no flow.  but i don't know if they ever quit or just run full speed all the time.  maybe i should leave well enough alone since i just finished about a thousand miles in 90 degree outside temp and the bus ran great at 65-75 all the way, temp at 170-180.

but i've got a leak around the hose in back and i'm concerned that the hoses may be wrong.  can one of you send me a diagram that shows how the thermacouple hoses connect to the rear.  i've got two hoses connected in the front to the thermacouple which is connected to the cooling system.  those hoses are about 3 feet long and connect in the rear area near the back of the engine. 
the manual doesn't seem to say much other than it's hydraulic.  help, again please.

manasst,
 I can take a few pictures of my setup if you want me to tonight and post them. I have the hydraulic fan setup also. I just finished pulling my radiator out and cleaning grime and oil off the engine side to help with my cooling. Let me know if a pic will do. thanks

pics would be great!  the hoses i'm talking about run from the 2 connectors on the thermocouple straight back to a connector right along the frame just behind the rear duals, driver's side.  when we disconnected them last year until we got a new thermocouple, the guy that did it never made a note as to what went where.  so when i hooked them up, i tried to connect where they seemed to fit best.  now that i have a leak on the rear area, i want to make sure it's not becuase i hooked it up wrong and the fan is still running at full speed all the time, although that's better than too slow or not at all. Wink

since you just did your radiator, maybe you could come up and show me how to do mine.  we're only 3 hrs from you.
also, since you're so close, are you part of great lakes converted coaches.  George myers is just down the road from you.  there's a surplus and salvage rally in Elkhart this month.

I have had that pump repaired twice and it is leaking again.  Is there a better system that will hold up?

Yes there is in your 15 manual it shows the 3 different fan drives,with yours the Prevost type is the easiest with just the angle 90 at the fan and belt driven

good luck
