On my 07 crew we screwed up an opened the seal cap on the radiator before opening the pressure cap on the bottle. The engine was cold at the time but it still proceeded to squirt some antifreeze out of the radiator, to the point where you can see the cores of the radiator. Question now is what is the best fix for this? Do I need to add antifreeze to the radiator? The bottle? Am I going to need to have the cooling system bled? I had a new radiator & cooling system flush not long ago. Thanks in advance for any advice.
