If your truck doesn't have a drain plug on the radiator, just remove the lower hose and place a container underneath to catch the coolant. there should be a petcock on one of the lower corners of the radiator. it would more than likely be on the engine side (as opposed to the front of the radiator). with the engine cold, remove the radiator cap, then unscrew the petcock. catch the coolant in some sort of container as it is illegal to dump it into the environment. its also very toxic to animals.
