First off I would like to state that I am satisfied with NAPA and will continue to do business with them and this is not a NAPA issue, it is a AC DELCO manufacturing issue.
PLease read what I have experienced today....

Also I am aware AC Delco water pump is made in china BUT,

Yesterday I order specifically an ac delco pump since it is OEM fit and was recommended by most as good quality and 100 percent direct fit as it states on the box.

Now heres my experience as it came today since 6am this morning...

-As I aligned the holes on the dowels of the block to seat the pump. The left hole on the pump was tiny and wouldn't fit .The right one was fine but still didn't fit 100 percent. The left hole on the pump would not even slide over the dowel on the block and luckly I noticed there was 1/4 space between ..I couldn't have caused serious engine damage. So I had to drill the holes out on the pump to make it fit. That was the first disappointment here. (I have had Chinese pumps over the years and never had a issue like this)

- Also I noticed the o-ring on the pump spline was free spinning and very loose. It looks like a person just threw one on there that was off something else in the factory. ( I don't think that should be that much of a problem in the future, I hope) Im sure it will just settle in with heat and time...hopefuilly

- And the left coolant onnection line on the pump is bent close to the pulley. When you put your hose onto it it will rub , so I had to tape the the hoses and zip tie them slightly out of the way. IF you don't it will rub a hole from the pully in the hose.

- Also I noticed a big gob of plastic epoxy just inside the water pump before I cleaned it. Must have fell in there from factory Imagine if that got caught in the propellers.

NOW
After bitching to Delco , they told me that they make a OEM line and a aftermarket line . SO my response was " Isnt all Delco supposed to be OEM ? That is the main purpose why I spend the 120 to buy it so I wouldn't have any installation issues. I bought a ac delco item which is supposed to be original then it didn't fit and when I called.

I am aware it says china on the box! But then it should still be a OEM part made in china TO delco specfications ..BUT delco says its not it is aftermarket universal

This is deceptive and bate and switch

I paid ac delco oem price for a aftermarket item whch was universal Im not buying again!!! I could have very well bought a duralast or any other Chinese item...
The main reason why I bought delco was because it is OEM part!!! I got rooked..

Beware you will be told your getting a oem part from delco but it is universal aftermarket

Boycott Delco!!!

I think this thread should be a sticky to alert people thanks

I hear your frustration.....but if it were me when the dowel holes did not line up and were to small...I would have taken the part back to place of purchase and gotten another brand or at least another AC Delco if that casting was better. The angled heater feed tube being positioned so the hoses then were in contact with something offending also would have been a red light.

Obviously you drilled, zip tied, etc to resolve these concerns but the fact those actions needed to be taken shows a sub-par product. Sadly when manufacturing goes off-shore the quality of materials and workmanship typically declines.

Now that the pump is on...hopefully it will be trouble free for years. IMHO I feel that with its weep hole in the back of it the Opti suffers from coolant exposure when it weeps which is why I went EWP 16 years ago. The EWP has FAR outlasted the mechanical AC Delcos (when they were made in USA) for me

Thanks and I appreciate your feedback .To be honest im soo drained out and disgusted with all this . I lost interest and don't enjoy my car anymore due to the fact that it is a ticking time bomb for a tow truck lol Seems GM can never get their designs right.
I am just going to use the car locally to go the the market and that's it from now on....
Im physically depleted !!!:(

While I understand,and sympathize with your frustration. I've found AC Delco parts to have a far,far better track record than any other manufacturer/re-builder. I'd be pissed off too,but what are my options? Start using A1-Cardone parts? I would have returned the part. Mechanical waterpump issues have been a thing of the past since I installed an electric one 15-16 years ago. Replaced one 8-10 years ago,but it had not failed. I kept it for a spare,and haven't needed it yet. Longevity of electric pumps are substantially greater. Plus,one can be swapped out in a matter of minutes. One no longer has shaft alignment issues,or weep hole leaking issues for that matter. Probably the two most common water pump problems...

Thanks very true. I will look into that electric one down the road if I decide to keep this car that long. I had it since 04 so we will see.
But I agree with what your saying , we are stuck between a rock and a hard place.
I have should have bought the USA Tough Stuff from Summit racing.They had it for 100 bucks but we will see.

These cars are hitting 20+ years old now and OEM parts are scarce to non-available anymore. This leaves the part store bulk manufacturers the only source for WP's, etc. even for labeled brands "AC DELCO" are all made off-shore and it is only about making if for lowest cost so materials & workmanship also suffer

Alternates, for a WP, could be the Tough Stuff one as it states it is their own casting & internals.

Or EWP and I use/recommend the Meziere

But don't these USA companies that are no longer makin usa products understand that when they offshore their stuff ......people will complain about the bad quality and not purchase anymore from them and they will loose money? Even though the item is cheaper???
What is wrong with us Americans always wanting cheap priced stuff?

When you save you wind up spending more in the long run to undo what you did???

What is the world coming too!!!

What do we make still make here?

And then these American companies have the god damn nerve to write on their packages saying.....made in America, mexico, china and also various other countries....

WTF?

ok, my ulcer...calm down....:mad:

Bitch all you want.

Did you ever realize that the part you got could have been returned to the store by someone else that put an inferior part in it to get there money back?
Seen all too often.

Possibly but highly unlikely. The item was in new shape , never ben installed or anything. Sure maybe someone could have swapped it out but why replace it with one that is new condition...

Im not bitching im just laying the facts of poor quality....how can you say that is bitching...when its seen soo often...

your comment is not valid due to those other defect issues...seriously!!!

I work in the auto repair business. I see stuff like that happen all the time. It happens & there is always shady walk in customers as well.

electric water bump model#

Meziere electric water pump is very highly recommended by the forum members. I have a 1996 Impala SS and need the exact model# of the pump. also do I need a base for this pump. I saw that there is a base for sale in the impala superstore. Is this needed for the water pump? What exactly do I need for this conversion. After reading all the post in regards to pumps, I 'm leaning toward this EWP. There is one on ebay with an auction listing model# wp118hd with no bids. Its a used pump. looks like its in great shape. very clean cosmetically. Is this the model i need? please help. Thanks

Hell,one of our forum members has two Meziere HD's for sale right now. It basically attaches to the stock casting in place of the front cover (once the guts are removed) Nothing else is needed except the "freeze-plug" that fills the hole in the back of the pump. I think one of the Meziere's for sale comes complete with housing,but I'm not sure. Check the "for sale" section...

I agree with you...people are douches and shiesty..

but this is your typical out sourcing of poor quality American crap that got my goat today and will remain getting my goat :(

Not wise drilling out the pin hole. That casting was off for whatever reason and it should have been tossed back in the box to return. The pins align the water pump drive shaft (to be square). Too much play in the bolt holes without them.

You would know if you were far off as the steel coupling would screeech while rubbing on the boss in the timing cover ... which was GM's brilliant idea to warn you of bearing wear or drive misalignment ... idiotic.

Thanks for the response I will look into this.

I also noticed that when I took the old pump off....the top of the optispark housing had a very small valley in it like the waterpump coupler was slightly shaving it off.
I have no idea why..But I can say that I triple check my installations every time I do work on my impala and this must be a design issue...anyone seen this?

That is exactly what happened when I bought an AC Delco blower motor for my ex wagon, I thought Inwas getting an exact copy of the original one but it turned out to be just like the one from Four Seasons and the Delco part was twice as much, AC Delco is just hype.

Classic example....You don't always get what you pay for...
