The smog air pump on my 1996 E350 Chateau is bad and making a loud squealing noise. I've looked for a replacement pump and no one has them. Dorman has discontinued them. I looked for a bracket with an idler pulley to replace the pump and can't find one either. I have to remove that pump the noise will drive you crazy. But what do I do?
Thank you in advance
PS It has a 460 ci engine.

 

I would try taking the pump apart to see what's up with it. There's really not much to them, might be a simple fix.

 

On the 460 no pulley needed, remove pump and purchase a smaller drive belt. The alternator has a lot of travel for tensioning the belt. If you google desmog 460 efi you’ll find some belt #’s on the web.
I take it that the vehicle is exempt from emissions testing either by GVW or year in your state ?
Some states still require all components that are on the under hood label to still be installed on the engine to pass inspection.
If you remove it what are you going to do with the air tubes that connect to the cat and exhaust manifolds ?
The 96 -97 California Emissions 460 didn’t have air pumps but were Mass Air vs Speed Density FI.

 

It is interesting that you brought up the issue with emissions testing. When I first got my van, a few years ago, I took it in for inspection and the inspector told me that there was an OBD2 port but it was not connected to anything. And said something about that the 1996 1 ton trucks were exempt from OBD2. I've tried searching the internet to confirm this but have not found it.
I will look for information on a different size belt and by pass the pump. BTW the van does have the pump.
Thank you

 

I can confirm that in NJ any vehicle from 96 back is exempt from motor vehicle inspection. I would assume most, if not all states would be the same.

 

Texas emissions inspections vary by the metro area you are in. There is a rolling 25 year rule. Vehicles 25 years or older only have to undergo a "safety inspection". They check lights,horn, and I can't remember what else but it is a very cursory inspection.

 

Are you in California? If you are I would not remove anything unless you are 100% sure it is exempt. I am in Ca and my 94 club wagon must be tested

every 2 years. When I take it in they inspect everthing and if anything is missing, not installed correctly or doesnt look right they will fail it.

I dont see how a 96 E series could not require a smog test in Ca unless its diesel, then there might be something different with that.

Every state has its own smog test requirements and some places you dont need to test it at all.

Dont quite understand what OBD2 being exempt means, that is a diagnostic system. It could be that he meant in your state the inspector is not

required to read any codes, I have read that reading codes is part of a vehicle safety inspection test that some states have not related to a smog test.

Maybe you can find a new old stock smog pump on amazon or Ebay.

 

I am in Texas and since my van is not 25 years old yet it requires to be inspected. But inspections are not as stringent as CA. The inspectors do plug into the OBD2 port and if there any codes for the engine they will fail the vehicle.

 

According to Rock Auto the ford part number for thew [pump would be E8TZ-9A486-D
RA also lists a Crardone part number so, try a search for cardone 32623 and see what you come up with. I did a quick search and it showed peep boys and O'Reilly's has one.

IF you go to this page and click on "view all replacement parts" It will bring up 2 different cardone part numbers that that site claims will fit.
Cardone 32-623 and Cardone 32-610

If the Cardone 32-610 will work, then here is one at ebay

hope some of this helps..

 

Thank you very much for your help. The first place I checked was RockAuto and it showed a Cardone pump but it said it was out of stock. CARDONE32623{#E8TZ9A486D}Remanufactured.

 

This sit shows that there are 2 different interchange parts from cardone
https://www.yoyopart.com/oem/1424995...8tz9a486d.html

 

If you scroll sown the page, for the link you sent me, you will notice that Cardone 32-610 fits 1988 to 1995. Cardone 32-623 fits 1996-1997. Since my van is a 1996 32-610 will not fit.
Thank You

 

Well then! I believe i tried to help someone a while back find one of these pumps.
Apparently Cardone rebuilds these pumps for almost all the parts stores across the country. i called them and the said they have a R&R service. They told me that any of the Cardone authorized resale stores can send it in to be rebuilt. So I called oreillys and they had no idea what I was talking about.. Any way here is links to call cardone.

Now there is a site called RearCounter who I often check for hard to find parts. They show someone in Kansas has one. I had to use the Ford part number so if it is a new Ford pump then it is probably pretty pricey but maybe worth a shot to check it out.

I am sure someone somewhere has one sitting around that they have forgotten about but that doesn't help now!
I don't know what codes will be set or problems it may cause if you delete it. Perhaps you will need it at one point in the future for emissions inspections.
If It were me, I would probably follow up with the R&R or maybe first try to take it apart first and see what I could find. From what I have read the problem is finding parts to rebuild one at home. I did read where one guy said after removing one of the bearings, he found the part number on the bearing itself. There are a couple of videos out there but none really in-depth
Good luck

Anna,
Thank you very much for your help. I did call Cardone repair service and got the same response. I went to AutoZone and they said they knew nothing about it. Sorry but we can't help you. I'll keep looking and check on that link you sent me. In the meantime I am going to get a shorter belt and by-pass the air pump and see how that works.
I appreciate your help.
P.S. Years ago I took apart a power steering pump and all sorts of parts (mainly springs) went flying throughout my garage. I had no idea what I was doing so I got one from a junk yard.Since then I have been hesitant to open a component and "fix it". BTW I did see the videos on rebuilding a smog pump and it did look much simpler.

 

Big difference between a power steering pump and a smog. At this point you really don't have much to lose.
