Unless your pump arrives with the 12558870 casting number on the side of it, I would not bother changing it unless you plan on trading the coach in. The correct water pump uses a much larger bearing and is a heavier casting to handle the weight of the rotating mass. My old pump weighed 19 pounds. Your labor will be the same either way but I would definitely make sure you use the correct water pump. You WILL NOT find the GM 89017773 pump at Rockauto.com with the correct casting number as shown in your u-tube video.
