2020 eco diesel antifreeze change, where is the drain?

[case310350]

should be simple but how do you drain the radiator?

There thould be a drain petcock on the lower pass side that you can open. But once it get low you can disconnect the lower hose and really get the fluid out.

@case310350 look into using a vacuum coolant filling kit to ensure there's no trapped air when refilling the system. Unlike the gas powered trucks the EcoDiesel doesn't have a coolant overflow tank, it uses a degas tank. There's not much extra coolant in the system.
