I'd compare the impellers of the original and new. I've read of some other makes receiving a crappier impeller wherein the delivery wasn't the same in volume or pressure, not sure which. The suppliers had switched to an impeller from another application which wasn't a good replacement.
GM thanks you for being a sucker. ACDelco is just GM version of Kenmore that slaps the name and high margin and little to no warranty for same part made by X maker. Nearly all parts are China made. Including most claim made in USA have important China parts in them like most to all rear hubs for Fiero.
Won't buy NAPA parts for same reason. Put name on X, jack the price, little to no warranty.

The reality is China is involved in most parts anymore.
While some things may be junk many are fine. The key often is to keep with a name brand or a Company that stands behind the product.
I deal with some product that we have made overseas. We have few issues and we use MFGs that keep American in plant to make sure the products are made to spec.
I also deal with a brake company that had to move their rotors overseas. He has had good luck with most of their work but. He has to rely on the Chinese to get things done. In his case when he orders everyone speaks English. When there is a problem no one speaks English.
But as long as people continue to buy the cheaper products. China is going to be a factor.
While some of their stuff is junk most of what they make is as good as any. These are the same folks making all of you Apple, Samsung and other computer electronics. That is what is so troubling is they not only are being us on price but can easily match us in quality if they choose.
India is also a major auto parts mfg today.
Also don’t be fooled by some product that say made in the USA. They may be assembled here but al, the parts are made overseas. They may just finish machine here and assemble.
We need to understand in China many of their plants and foundries are no longer the huts we say 50 years ago. Most are new state of the art facilities and the only thing that separates quality to non quality is the designs sent to be made.
Everyone complains about China but they all go to Walmart and Cosco to save money as they are unwilling to pay the price on many products to be made here.
I just pray we get our medications back. But with mfg as it is we are at a very strategic disadvantage.
Sadly there are many elected officials willing to send more companies to China.
I bought a remanufactured unit from Rockauto just last week. It was Cardone brand on closeout for $8.86. Looks just like the original I pulled off the 2.8 only it had an outlet where the original has a plug. Is new really better than remanufactured? Well, as least as water pumps go?
I installed a new pump that I purchased from O'Relyes. Sorry, I forgot the manufacturer, but it works just fine. While your in there, my Formula had torx head bolts holding it on. I found that unusual. I replaced all of them with standard hex head bolts.
I agree that a lot of stuff that comes from China is junk... BUT the reality is that China can build anything just as well as USA/Canada. It all comes down to QC and Engineering enforcement. Country of manufacture really makes no difference anymore. A guy turning a wrench or running a CNC machine in Shanghai isn't any less talented or dedicated than a guy in Indianapolis, Toronto, or Buenos Aires. They have access to the same technology, software, inspection equipment. The Chinese can and have built spaceships, MRI machines, satellites, and other highly complex pieces of equipment.
The bigger issue is the QC requirements of the companies that outsource work to China. For example, if AC Delco or anyone else would be willing to enforce (and penalize) Chinese suppliers for poor quality parts, sub par materials, etc, then the quality would improve, but the price of the part would go up.
Bottom line- there is no way to get something that is high quality for a dirt cheap price. The math doesn't work. I certainly hope the supply chain returns here to North America, as well as the manufacturing jobs that left in the last 25 years....
The difference between the Chinese and American/Canadian/European/Japanese made water pumps is in the bearing and seals. The Chinese can make decent castings (sometimes) but the quality of their bearings leaves much to be desired. We've seen that with the Chicom bearing hubs that sometimes don't last long and fail. IMO, buying Chinese is a crap shoot. Sometimes their parts are very good while other times their parts are very bad. The Chinese sell on price and to be competitive they tend to cut corners. The problem is their stuff doesn't hold up and they've gotcha by the balls. If you buy a rebuilt water pump it will use Chinese parts. When I did my 4.9L swap I ordered a new water pump. I chose the Bosch brand expecting a USA or German manufactured item. When I got it from Rock Auto it read Made in China.
