I never noticed a hole in the shipping box at the drain plug area when it arrived,I Installed it today and started to add anti freeze and saw that it was leaking at the drain hole area needless to say I am very disappointed.Everything about the radiator was perfect new in the box fit etc.,I don't think this was sellers fault it happened on the way to me I believe.I have returned it,and reordered another from same supplier this time thru Walmart as I saved more cash with cap one shopping.
