I was hoping the RV Wizard could have responded here to your request or Rusty and I expect they will just give em' a little more time!

You might want to root out EngineerMike and send him a PM.

I ran SCA in my Powerstroke diesel and I believe I drained some coolant down in order to make the adjustment. But that was a while ago!
