craigc51.  Welcome to the Forum!

It would help to know Make, model & year of the RV, also year & model # off the generator?

That page only talks about draining the coolant if you are removing the engine. Nothing telling where the drain is or how to fill.

About all I can offer is call 24/7/365 CUSTOMER SUPPORT United States & Canada:888-GENERAC (888-436-3722) see if they can help.

 Thanks to all who responded. I finally found out there’s a small   bleed screw  on the bottom of the unit.  You don’t have to remove it  all the way  to drain the  coolant .  there’s also a petcock right above the engine oil filter to drain  coolant out of the motor
