ACDelco Gold 252-845 (19195104) Engine Water Pump

Gaskets where hidden under the bottom flap in the box. They should put a note explaining this. I almost purchased new ones when I didn't see them in the box. Part fit great and went together without any problems. Do wish the part had better packaging inside the box to support the water pump. Box was thick though. Quality part as far as I can tell. My Chevy is back up and running great.

Perfect fit and not one leak! I installed it myself. Adequate delivery time. No complaints! I would definitely recommend to others. First time changing original water pump on my 2003 5.3 V8 Tahoe. Thank you so much. My old water pump was noisy and leaking. Agin, perfect fit and for the first time in a long time don’t have to top off or refill antifreeze reservoir.

Good brand,good price.worked as it should.

This OEM product was a perfect fit for my 2003 Chevy Silverado 4.8L. I would highly recommend!

This water pump worked great, no problems and easy install.

I bought this pump to resolve a coolant leak. I figured it would either be the gaskets or the impeller shaft seal, and I didn't want to tear everything apart just to replace gaskets.Well, it turned out to be the gaskets anyway, but this AC Delco pump is a good product. It, of course, fit precisely into place and was of good construction. The casting for the inlet/outlet ports had some slag left in them, but that's really the only problem with construction. It came with instructions for installation and an O-Ring or Paper Gasket for the thermostat housing (depending on your particular configuration). The holes tapped for the tensioner had no problems when I inserted and torqued the bolts.It also came with (2)impregnated rubber gasket plates to go between the pump inlet/outlet ports and the engine block. I ordered 2 gaskets from rockauto made by AC Delco before ordering this pump, since I wasn't sure if they would be included. The gaskets I ordered separately from rockauto were of better construction than the ones included in the box with the pump, which is strange considering they're both AC Delco parts.The impeller shaft appears to be made of a good grade of stainless steel and is threaded very precisely for attachment of the fan clutch assembly. It is protected by a blue plastic cap to avoid thread nicks in shipping.The only other drawback is that this part had "Made in China" laser etched into the pump housing casting. I'm not sure if the parts are sourced form overseas vendors and then assembled in the US, but either way it's a turn-off.I give it 4 stars because at least part of it is made in China, and the included gaskets were not very impressive.

Excellent - no issues

Perfect fit and function for 2001 Silverado 2500HD 6.0.
