GM Water Pumps

[More Power]

2001-2005 Duramax water pump.

What's the difference between the two following part numbers?

ACDelco 252-838
GM 19168888

Thanks,

If you wanted to roll the dice on one that is not welded I would try the GM number. See if you can find the country of origin. if it's made in Japan you may be good to go. If China I would weld it for sure.
