How often are you guys flushing your cooling systems and replacing antifreeze?

I prefer the Fleetguard (Cummins) or the Fleetrite (International). Both coolants are designed specifically for diesel engines. There's nothing wrong with the Gold, it's just that the two mentioned above are better...IMHO.
Run the truck for a while so that the t-stat opens. Also, make sure you turn on the heat inside the truck.
