Which of these two Air Pumps will fit? 2 Different Parts list for Replacement for SL1
 

According to alldatadiy.com regarding the replacement part for the Air Pump
To 6/00 = part number 21015056
From 6/00 = part number 21015184

Which of these do I need? I have a 2001 Saturn SL1

However, don't know what 6/00 means. How can I use that value to identify which part I need?

Well, I do have a Sedan so it would be part # 21015184.
However, I am still wondering what 6/00, as understanding that value will help me in the future.
What's more, 21015184 is a hard to find part, while 21015056 is very easy to locate.
So, can I use 21015056 in in my Sedan 2001 SL1? What's really the difference?

Thank you,
My production date code is 11/00 so I have that answer now.
But, can I use 21015056 in in my Sedan 2001 SL1?
I can't even find a single new 21015184 anywhere.I've searched a whole bunch of car part stores and websites. Yet, the 21015056 is sold all over.

expensive but pretty meticulous about online listing updates

Thanks def,

I called jegs and they our OOS, and simply said that this item has been DC'd and that they will not carry it. He was super amazed that I found it on the website!

Stockwise atuo , shows 0 available.

Thanks for the link to Tonkin, though for over $300 for the pump, you're right, they are expensive, like triple the original price.

Okay guys, get this:

I noticed on my Air Pump and also on some I see on pictures for part # 21015184
The following text occurs: Pierburg PA6-GF30
When I search for pumps with Pierburg PA6-GF30, I do find results that look just like mine, and for $100 bucks too, new even.
I'm thinking Pierburg makes the same pump for different makes, and each make has it's own part #...
I just bite and tried this: https://tinyurl.com/yclh2pz4

Did you ever get this problem solved?

I'm in the same boat as you. Need the 21015184 air pump for my 2001 SC2 and cannot find it anywhere.

What was your end solution?

Josh, the last replies to this thread are over a year ago. I'd suggest you try the link to jegs or stockwise that derf posted and hope for the best.

Thank you for your help. I actually read this thread from the beginning and saw those links.

Yes, I do realize that this thread is over a year old but the author never stated his outcome or solution so I was hoping that my post would have alerted him to a new post in this thread.

The thread was still open so I thought it ok to respond.

I'll try PM'ing him thanks!

Hi Josh:

It turned out that my pump was actually good. I tested it by plugged my old pump directly into the battery that it did work perfectly.
The real problem was that the air pump wasn't getting the voltage to turn on when it should (when the car is cold, for about a minute).
I took the car to the mechanic 3 times and they kept saying they fixed this and that, and each time by the time I got home the check engine light went on again.
I even setup a remote connection to the battery so that I could force it come on with a click of wireless button for the first minute after starting the car, just to prevent a check engine light from coming on long enough to pass emissions. (didn't work; well it worked but the check engine light came on anyway)
Fast forward and after months of driving illegally with an unregistered vehicle (what could I do, even the mechanics could't fix it? Otherwise it was running perfectly),
for another project I de-greased everything under the hood with purple power,
and viola! check engine light went away and never came back on!
I've never had a problem since. My guess is that I washed away some corrosion interfering with the wiring.

So, that first thing I would do in your case is just to make sure the pump is really bad by seeing if it works by wiring it to the battery. Perhaps, like me, you have a working pump, but it's just not getting the voltage it needs to turn on.

I hope that helps, and good luck!

Thank you for the response. I watched several video tips about checking the power and verifying that all hoses involved were clear. I'm hoping that this is the case and I won't have to resort to finding a new pump or shelling out $300+ for one.

Thanks for the help!
