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?
