I ran Power Cool Extended Lift Coolant in my last bus (2005 Royale) and I'm running the same in my current bus. Prevost did the conversion on both. Multiple flushes with running the engine between flushes. If I'm not near Prevost or a Detroit Diesel dealer, I use Final Charge (buy it at O'Reilly's) to top it off. Just make sure you are adding "OAT". Organic Acid Technology coolant once you are on the Extended Life Coolant. Power Cool ELC is OAT and so is Final Charge. Mixing OAT and traditional coolant is a worse idea than killing the XL Pipeline........

Prevost Wintergarden flushed ours last year after the show. They used Prime Conventional Green by Prestone.
