I'm looking for an air diverter valve ; see discussions on them ...has anyone found them yet?

Are you looking to purchase one or the location on the vehicle?

looking to purchase a new one (air diverter valve GM part #17090215)for 90 Caddy DeVille 4.5 L FWD

A dealer is the only place you'll find a new one. That is if they haven't discontinued them.

Just to add to this one is the pic i posted the part your looking for?

statech- thanks but, no, it is not the right part. what I'm looking for has a whole lot of ports on it, is black, looks like some sort of spaceship, more cylindrical or tube-like than square, ..looking for used or prefferably new. Not even Cadillacs Only has one. GM part 17090215, AC Delco #214-123 SMP #DV84

So is theac delco number all together including the dv84 the way that number is posted its a little confusing.Iam really good at finding parts thats why i chimed into this onethe challengeto find thr part.

No, sorry. The AC Delco # is 214-123 The other is Standard Motor Products (or Parts?), but SMP DV84. Sorry for the confusion.

any ac delco parts store will have it or it can be ordered

You can try calling one of those ac delco stores i have been putting those part numbers into the websites that sell ac delco parts and it comes up as part not found.Try this go to www.parts.com and get the phone number off the website give them a call and see what they can find for you.They sell factory parts for all different kinds of makes.There a parts locator i have bought parts from them before they found the parts i was looking for.Let me know what you find.

this is a discontinued AC Delco part, also discontinued by SMP, and has been called 'the holy grail' of Caddy parts by noneother than Cadillacs Only in CA.I found one place that says they have 3 of them , but they are unable to find them in their 45,000 square foot warehouse amongst their 32,000 parts bins.I even told them that I would buy all three. Whether they are looking for them, they didn't sound too enthusiastic even though I offered them extra money to look.

It felt like i was looking for the holly grail looking for that part.Looks like your headed to the pick a parts for the holly grail thats where i would go look next.Keep us posted on the hunt for the holly grail lol.

why ars you replacing it.there is a valve mounted near the vacuum pump connected by hoses.is that it?

being replaced because it is failing( according to my local Caddy dealer) and , though it does so not instantly, it goes quick; when it does, the car will not operate. It is behind the rear valve cover, on top of the motor, with a handful of hoses and a couple of electrical connects on it. It is impossible to find. Though the dealer had cleared the trouble code, my Service Engine Soon light just came back on today, which means failure is immenent. Once this happens, I'm letting this car go. It won't be possible to fix unless that part can be found. Anybody???!!!

you need to look at the salvage yard and if no let them put it on the part locatior see if they can find it.push off and warmer buttons on the a/c panel.then write the code on the fuel center. id like to know what code its throwing.i never have replaced that part in my whole carreer.

just was at my mechanic today with code e049. confirmed it was diverter valve 17090215. do not panic. this part is an emissions only part. it moves air from intake to exhaust and back. he told me only consequence is worse gas mileage and you will add pollution to air. i am disabled so this is important to me. he guaranteed this will not cause my car to break down and leave me stranded. anyone else hear different, please jump in and post your info. i spend hours every week looking online, salvage etc. have ads everywhere no luck, but i'm still driving my 90 eldorado and it drives fine. i don't know who told you it will just die suddenly. what could cause that in respect to this part? i think there is a lot of bad info out there. i should be panicking because i can barely walk. let's hear from some others with experience on this subject. i also don't want to lose my 68,000 mile mint car. i hope i got right info.

what code is it setting.get the trouble code and follow the tree for dianoses

I have located a similar part on ebay, item #360180589973. I know what you are after, and it is discontinued from GM. Look at the illustration on this ad, does it match what you are after? It states an application of 87-88-89, I wasn't sure there was a difference in that valve, but I may be wrong.

Usually, it is one of the vacuum solenoids that fails on these. If I am not mistaken(haven't seen one in a few years), both the diver solenoid, and the switching solenoid are the same parts, and sub-parts of the combo valve. If you can find a used one, good or bad, it may have some salvageable pieces to make one good one. Of course, you will have to do a bit more thorough diagnosis on the component itself to determine this, but it can be performed.

my car is throwing e049 so i had diverter valve physically taken off the car and mechanic confirmed it was one of the solenoids. air pump is providing air to valve so it is doing it's job, but my original question still is, what makes anyone think a total failure of diverter valve would cause your car to be inoperable and need to be junked? my mechanic who only works on classic cadillacs, did mine because he loves my car, emphatically told me that it will not affect the driveability of the car. it is strictly a part that recycles air to efficiently burn any excess fuel in the exhaust which is why it starts off diverting air to exhaust and then when warmed up, back to intake. can anyone tell me why or how this will cause your car to die even if failure is imminent as dealer told 1st poster. it does not make sense. none of the answers adressed this. you can live with ses light on. if another problem comes up your dic will inform you with new code. someone please comment on this aspect. yes we all want the diverter valve, but it just might not happen. do we all have to sell our cars for salvage? i for one have invested much of my own time and money to make my car look and run perfectly which it does still with ses light on throwing code 0e49. let's hear some different answers besides look for the part in junkyards. is this part absolutely necessary to keep your car running or just an emissions part? this subject is on every forum and is controversial, but there is only one truthful answer. dealers have no interest in working on your 22 yr. old car. i called 4 dealers and got that same answer. the part is discontinued so that's the end of the story for them. unless you have a new escalade where they can throw an overpriced part in and then overcharge you for labor, they want nothing to do with you. that's how they make their money, not keeping old cars running. they can't even diagnose things anymore. they are just parts changers. since they don't have this part they can't make money. they'd rather tell you to junk your car and buy a newer caddy. anyone have the definitive answer, is my mechanic right or do you believe the dealer's scare tactics? i am losing sleep over this too, so let's hear some logical explanation of how the failure of this part will cause your car to be terminally inoperative. sorry for long post, but this is not as simplistic as try to find one in a jnkyard. what if we can't. thanks

i remember this valve.it was right behind the vacuum pump.its was on every cady built back then.if you clear the codes and it keeps setting its a hard code.the valve has to be replaced.the emissions are the only thing effected.find out how many years thay use that same sensor.go to the salvage yard if they dont have one they can put it on a part locator.and they garranty its good.

Cugino, you have already been told that it is just an emissions part, responsible for lowering HC and CO out the tailpipe. Whether or not you think this makes your vehicle junk, is your discretion. I can't explain why your dealers want nothing to do with older vintages, we gladly accept them. There are only so many avenues that we can travel down to find a discontinued part, and the consumer is not going to fund the 'end-of-the-world' search. That is where this forum comes in. What doesn't make sense, is after you have been told it is just an emissions part, and there are no detrimental effects other than emissions test failure, you keep beating the dead horse. As far as not being able to diagnose things, you could have put the injector, air pump and such that was recommended to you from others. But when you were advised to function test the valve, you found your cause. The reason there is so much on this post dealing with simplistic things like finding one at a junkyard, is that the title of the thread was 'looking for a diverter valve', not 'looking for a scientific explanation as to why a diverter valve makes my car salvage'.

I was the original guy looking for the diverter valve, still haven't found one. I had two shops (a Caddy dealer and an independant shop) tell me that once the diverter valve goes, the car stops. They weren't sure if it went suddenly or slowly went bad. It is good news that it won't cause the car to stop, if indeed that is true. I did find one place that said they had 3 of the diverter valves, according to their inventory computer, but didn't know where they were among their 32,000 parts bins, and I even offered to pay someone on their staff some extra $$ to take the time to search for it, but they didn't go for that. So, I ended up buying another 90 DeVille, a coupe, with 100K on it (half of what my sedan has) and am using that.The sedan still has some major oomph in it but though I've cleared the E49 co0de (AIR system fault), it comes back on after a while and I'm hesitant to drive the sedan for fear of ot dying on me. I'd still love to fins a diverter valve...any one have one? And will look through ads for Caddy parts in Hemmings Motor News.

no need to get nasty. if you take the time to look you will see i am responding to the post from brian johnson in oct.that says his dealer told him the part fails quickly and makes car inoperable. you did not correct him so when i saw that post i just wanted to double check. i've heard so many conflicting opnions my head is spinning. just re-read this whole section, not one word saying don't sweat it because it's only an emmissions part. maybe someone on your site could have jumped in and stopped all the back and forth and told him what you told me. also, re-read my posts. different caddy dealers gave me different advice. same with mechanics. you are just one source. i don't know you or your experience so i have no reason to believe your opinion over a caddy service tech or a mechanic who has 50 years exprience. you should lighten up a little bit. it makes you sound like you are the last word. i'm trying to wade through pages of contrary information to get to the truth. i guess i won't be bothering you again.btw, just because the post's title is looking for a diverter valve, does not mean it is not full of misinformation that if i'm reading it, others are too. you did not correct him. that's on you. not everyone got your explanation to me about emmissions and even getting that, reading a contrary opinion on your site is a bit confusing to say the least. i don't need to get lectured by someone who is probably 1/2 my age. that is no way to gain customers. do what you want, it's your site, but i will not be visiting it again. part of being a businessman is customer relations. i doubt very much if you would talk to a customer face to face as you talked to me online. that's the funny thing about the internet. people say things because they are anonymous that they could not get away with in real life. you have a short fuse my man. you don't like your opinion questioned. if that's true you need to keep a better eye on your site so when misinformation is posted you can put an end to it. that's exactly why i posted what i did, because misinformation on this subject is all over the internet. sorry you took it the wrong way, but that's on you. see ya.don't think i'll donate either. very immature attitude.

gm used that valve on more than caddys.try to locate one.go to the dealer and get the part info.what years it was used.then it will have to be taken from that year cars.

brian, and anyone looking for gm part # 17090215 diverter valve, i found one @ cadillac heaven yesterday. they have over 1,000 60's - 02 caddys. check out their website. i think you'll be pleasantly surprised. ask for karen 800-227-9330. very nice and helpful lady. $200.00 plus shipping. great source for parts. i will definitely use them again.

Why buy used? If any one needs a Cadillac AIR Diverter valve I have a brand new in the box ACD#214-123 GM#17090215 I'll go $200+shipping for a brand new one. Bought it for my Caddy, but got into an accident before I got to put it in. Also have a ACD#215-344 GM#26006809 Air Pump new in the box for the same car $175+shipping.

Mound 98- it is a little hard to see the part in your picture but if it is the right part, I would like to purchase it from you. GM part # 17090215, your ACD part is the #214-123 I'm looking for. I could send you a personal check and you could hold the part until the check clears. I'm not sure how to contact you through this website. Not sure if it is allowed to send personal contact infothrough this site. But let's proceed.Thanks.

Mound 98 - I sent a response a few minutes ago but I don't see it yet, so maybe something is screwy with the site. I would like to get the diverter valve from you but am not sure how to get in touch with you; maybe personal contact info on this site is not allowed. I would send you a personal check and you could hold the part till the check cleared. Please let me know what you'd like to do. I'm the guy who wrote the original 'looking for air diverter valve' note.

Mound98-I sent two replies about 25 minutes ago, and don't see they posted yet, but I would like to buy the AIR diverter valve from you. I'm the guy who started this recent search for the part. I'm not sure how to make contact through this site; if it is allowable to transmit personal contact info. I would send you a check and you could wait until it clears to send me the part. Please let me know how you would like to proceed. Thanks.

Mound 98- I sent three replies the other day, buy they haven't seemed to show up on this site. I'll try again. I would like to purchase the new diverter valve from you. Please send contact info. Thanks, from Brian Johnson

Mound 98-I'm trying to contact you, but can seem to get through. Please try to contact me. Thanks. Brian Johnson

Brian, email me directly @ [email protected]

i posted this last week. this part is available @ cadillacheaven.com i paid $200.00 and $25.00 for shipping by fedex ground. got it in 2 days. it is in my car now and functioning perfectly. no more ses light. this site has over 1,000 60's - 02 caddys in their yard. they guarantee their parts as well and are very helpful, knowledgeable and all around good people. need an abs part and will be ordering it next week. your purchase is also guaranteed by your credit card so you know you will get your part. sorry, but buying from a private party you don't know is crazy. roll the dice. just like ebay. maybe you'll get the right part or maybe you'll get jubnk or worse yet no part. this seller may be legit or maybe not and what do you do if thetre is a problem? after many mishaps on ebay i only buy from ebay stores or established website. my 2 cents. i am very satisfied with cadillac heaven. if i have a problem i have an actual store with a real address to complain to.

Brian, I got an email from 2CarPros.com saying there is a new response, but no more info than that. Just directly shoot me an email [email protected] and we make arrangments.

Brian, this is the part you are looking for GM part # 17090215, ACD part is the #214-123. Brand new in the box, not some sketchy pulled used part.

nobody knows what you get when you buy from an anonymous person on internet. the part i bought from cadillac heaven is not a sketchy used part, but a GUARANTEED part from a legitimate company. the part is on my car and works fine. do what you want, but if this guy doesn't send you the part or it is damaged or non functional, do you know where to go to get a refund? your call. had it happen with private sellers on ebay. i only use guaranteed real companies not a post on a forum with no real name, address or refund policy. just trying to bring some reality to the situation. the internet is full of scammers. maybe this guy is legit or maybe he is a crook. it's your money. i'm just saying, i wouldn't chance it when there are guaranteed parts with refunds available who adverize in hemmings motor news and pay to advertize on other cadillac sites. i'm out of this discussion. you guys are over 21 so you're old enough to make a deal, even a bad one. if someone wants to sell a part there are legitimate ways to do it thru paypal etc. sending your check in the mail to a stranger is just plain crazy.

Brian if you didn't get your part for your caddy we have a new one in stock. Ac Delco # 214-123 or GM # 17090215 still in box. We are a shop located in Richardson Texas our number is 972-234-1299. Thanks Rod

Rod- thanks, I did finally get the part new from mound98. Maybe some other Caddy owner is looking for it, and if so, please contact Rod. Thanks for letting me know, though.

I am also looking for this part!! I have looked all over and can NOT find it. If you have it, please contact me at spam4ed (a) h**mail or on here, thanks!
