Airtex waterpump

Any thoughts on these? I can get one on rockauto for 15 bucks and I believe they make decent fuel pumps.

And you can get the ACDelco for $5 more. Why not get that one?

Thought about that too but being I am getting a new belt tensioner, belt, and idler it will cost more with shipping. Is the delco one that much better? I read somewhere that the replacement delco ones are no good

Opinions on these things tend to be all over the place! Having said that, if I were mail ordering mine I'd probably get a Gates.

I used to trust AC Delco until I got some brake parts that were built wrong..and most of the parts aren't made in America anymore so I don't think the quality is the same as it once was. I still buy AC Delco parts sometimes, but they may not always be my first choice.

they still have to follow specs and quality checks like anything else that's manufactured

many OEM parts come from mexico or elsewhere

I've bought ToughOne parts before... they're pretty good. I would recommend them.

Thanks for all the replies. Anyone have experience with airtex. The impeller looks different than stock

It's been so long ago since I replaced the water pump I don't remember what brand I used. Sometimes there are design differences between brands but the impeller should be fine.

The Tough One water pump for the V6 is assembled in USA. I'll take some pics and upload them when I get the chance.

I think the water pump design changed for 2002 or 2003. Early units used a cast impeller; later units had a stamped steel impeller.

Mine is an early 2003 and it has the cast impeller.

From what I can tell, some use a cast impeller, and some use a stamped impeller. The Tough One from AA that I saw had a stamped impeller. I have no idea if it makes any difference, except maybe in how much it weighs.

According a piece of paper that came with my new waterpump, bought today, all the new ones you can buy, even for an older Alero should use the stamped impeller:

I found 2 writeups, complete with pics in a Grand Am forum. I referenced them in my water pump thread here:
http://www.aleromod.com/forums/showthread.php?t=37682

What I was wanting from you was pics of the pump and box it came in. Those might be useful to other people here.

That and I am still investigating exactly why type of thread locker to use and where. I will probably get the pump today and read through the instructions that come with it and the Factory Service Manual just to see what they say.

Hello guys,

I hope anyone of you can help me with my problem. Picked up my car from the shop and they told me my water pump is broken. I took the car back home and on the way it started overheating. I stopped instantly and let it cool down. Then I checked the coolant and it is not empty. Nontheless the warning light is on. On the rest of my way home the car did not overheat again. The temperature was ok (?????) at least when the temperature display is not wrong. It is strange that the engine is running pretty rough when idling. In the beginning when the engine was cold it was smoking pretty heavy. This disappeared after he got some temperature.

1st question: Is the water pump really broken?

2nd question: I checked the waterpumps on Rockauto and for some reason the most are pretty cheap. Only 2 waterpumps are not that cheap. Can anyone tell me why? What is the difference?
