help I want to find the tank for the spartan fan

[American Eagle]

I have a 1999 American Eagle and would like to find the fan hydro fluid tank. My coach is running warm and would like to change the oil in that system. The coach ran over 200 degrees going to Sturgis and will be flushing the coolant out next spring and maybe take the radiator out too. Any help would be appreciated. Thanks

The tank is usally at the back of the coach. it is round, 10" and has a knob which is the dip stick and where to add fluid. If all else fails find the fan motor and follow the Hyd lines back to the pump and then the tank. My new eagle doesnt have a hyd fan. It runs on a belt system and an electric clucth. Hopes this helps.
