Thanks Unplanned!! This gives readers a quantative concept for the procedure. Who knows when some of us need to do it as anyone could accidentally pour a bottle of transmission fluid (red) into the coolant reservoir (OAT coolant red too) .
Best wishes to all!

I don't know what the factory defect was in the motor, apparently there was a substantial amount of oil in the water, Cummins paid for and installed a new motor, ($22,000) i cannot tell you if they flushed the hoses when they replaced the motor, a couple thousand miles later the hoses began to leak, he then paid $1,600 to replace all the hoses, i would think a cummins shop would have flushed the hoses, or, maybe it depends on the amount of oil that was in the water, the coach now haw 98,000 milles on it with no issue
