ACDelco Gold 252-845 (19195104) Engine Water Pump

Excellent and easily installed. Works like a charm so far

Well made product fits perfect-works well-for gm ac Delco is always the way to go for my old Yukon. They are a bit more expensive but they’re a hand & hand company with gm quality builds.

There are other water pumps out there that will "fit," but none of them will fit as nice as this one, made to AC Delco's original specs. Once you get past all the typical, unexpected headaches of getting into your engine compartment to replace a part like this, the repair is actually pretty easy. Barring any unforeseen headaches, even an inexperienced DIY'er could probably get it done in a hour or so, not counting any system flushing or other prep you might want to do before the actual installation. The "kit" comes with all the gaskets you need, and you DO NOT need to add any extra adhesives or sealants. That stuff just makes a mess on/around the mating surfaces and your anchor bolts. For example, my replacement project was delayed for HOURS while I struggled to extract the OE anchor bolts from the old pump body and remove from them all the excess sealant the mechanic who installed it had slopped all over the gasket/port connections. The bead of silicone around the edges of the gasket holes gets compressed between the mating surfaces when you cinch down the anchor bolts, and forms a perfect seal. The pump manufacturer supplies two of their own, "knockoff" version of the AC Delco gasket, but I didn't trust 'em. I ordered the AC Delco ones from Amazon. Note that you'll need TWO of these gaskets, NOT one. If you're also replacing the thermostat (always a good idea when you're changing out the water pump), get the AC Delco one, too. It comes with a built-in o-ring that fits neatly into the thermostat housing and also does not require any additional gasket or sealant. So far, this thing is running totally flawless, and I'm HAPPY that I finally yanked out the old, leaky aftermarket junk that was in there before, and replaced it with the water pump that was MADE for my 2001 Suburban. No more having to check my coolant level every other week, and I know this pump will last a very long time before another replacement is required.

Used this as a replacement water pump, and it was exactly what I was looking for—OEM quality without paying dealer prices. Install went just like you’d expect for this model truck. Everything lined up correctly, no surprises, and it’s been working exactly as it should. ACDelco has always been a reliable name, and this one held up to that. If you’re looking for a straightforward replacement and don’t want to overpay at the dealer, this is a solid option. OEM Quality—Without the Dealer Price.

Worked and fit great

Installed on 04 Tahoe 40k miles back. No leaks n bearings are holding up.

This was really a good price for a acdelco water pump. Lots of reviews on aftermarket water pumps failing after a year or two and replacing this on a GM van is a time consuming task that I don't want to do again in a year or two. Spend the money and get a quality pump the first time.

Item arrived new and packaged very well.

Lo recomiendo excelente producto buena calidad a buen precio

Perfect fit and very good quality and working great.

gasket were a cheap. Used better quality gaskets. No leaks after 6 months.

Excellent quality, fit my truck perfectly. Seals were good quality as well. The first one arrived damaged, but they quickly sent me another and I shipped the damaged one back at no cost. The second one was packaged better.

Made replacing the pump on my 2005 Yukon xl Denali 6.0 liter easy. Seems well built but time will tell. Fast 2day delivery.
