Hydraulic fans/draining hydraulic fluid

Seals are leaking on my cooling fans. Is there a shutoff or drain for the hydraulic fluid? How many gallons of fluid will be drained ( how many empty containers do I need).
Any other info that you have will be greatly appreciated.
Thanks
Ron

There is a drain plug in the hydraulic tank. But I just st siphon the oil off. Takes about 4 gal of oil. Are you going to do them with the radiator in place? Mine will need done sooner than later.

When working on the hydraulic system, keep everything surgically clean.  Any dirt or debris that gets into the system is bad news.  You should close up the ends of any hoses that are disconnected to keep dirt out.  They make special plugs for this purpose - called Parker flare adapter plugs.  See the post linked below for photos of these plugs:

I will have it done. I am to old and stiff to get under and around to do it myself. I wish I could do it. My radiator was replaced before I bought the coach about 3 years ago so i hope they don't want to take it off. I am sure it will need to be steam cleaned or something to get the oil off it. Do you know what pumps are on our coaches?

This might be a solution for our hydraulic fans.  The experts hopefully will give views.
