Quality part!
I will only buy GM original or ACDelco for my truck, 2005 Z71 crewcab. I’ve been there and done that with no name parts that are a fraction of the price. It’s totally not worth doing the job twice, three times… is it? Spend the little bit extra $$$ and buy once.. cry once. There, I said it. So this water pump is no different than any other GM original, works fantastic, fit perfectly, even came with some aluminum/rubber gaskets.. they rock! No leaks and no RTV necessary! I would buy this again without hesitation. The quality can be felt when you hold it. It fit perfectly and I used my old thermostat.. fit great as well. Do not cheap out on the water pump, buy OEM. Also stamped.. built in Canada. I would prefer this to China any day of the week.

Original GM replacement part that is identical to original on suv!
Quality GM original water pump! I used my original thermostat and housing with no issues! 2 Hour job! Thermostat hole in pump is same diameter as original! Aftermarket replacement pumps have larger holes with different thermostat housing. I like original GM parts better! 2005 cadillac escalade esv 6.0 engine
