You just discovered why you should not buy stuff like water pumps based upon price alone; you typically get what you paid for…… Rather than fuss with the knock off pump, I would either return it, or throw it in the trash. We have never had any luck with aftermarket water pumps on these cars, and the ones with metal impellers can chew the Hell out of your engine case when they fail, filling the cooling system with metal filings. Not a good thing on an engine with a lot of very small water passages……….. Buy an OEM unit.
