Hi All, I am making the switch to OAT coolant today on my 2001 Monaco Diplomat with the Cummins 8.3 ISC. After hours of research, I decided that to be the best choice, I will also change the gen to OAT as well. I will use the procedure outlined by @wolfe10 https://community.fmca.com/topic/3468-coolant-flushing-for-cummins-isc-83-that-requires-sca-coolant/?do=findComment&comment=18430. Also changing the hoses along the way. For those interested in my research here are a few links.
