What happens here
Place a large, suitable drain pan underneath the radiator's draincock. Open the draincock and allow all the coolant to drain out completely into the pan. Be prepared for potential spills, as hoses and connections on older vehicles might be brittle or release unexpectedly. Once drained, close the draincock.
Goal: Prevent spills and allow for radiator removal
