While looking for a possible minor vacuum leak after I installing OEM Cruise Control functionality in my 87 GT, I was having a suspicion about the EGR solenoid/valve. Now, I'm not getting any SES codes (CODE 32) at all, and I did the forum repair on this device 6 years ago (no ohms, broken coil wire @ solder post along with adding RTV to seal some areas as a preventative measure), but I was getting some minor air passing through it while doing tests as recommended in the 87FSM flow chart. So I decided to open it up again. Even with the RTV I put at various water entry points, the coil was rusted over sooo bad and the shaft going into the air filter looked like a 100 year old rusty nail, that it was gonna soon eventually die on me and short itself out to the metal housing then to the mount then to the engine. Off to the Internet and PFF.

The good news is, there is an EGR solenoid available (NOS for other 80's vehicles) that is a perfect match for our 2.8 V6's (2.5 also?). Since most of us longtime Fiero lovers are pretty good DIY'ers, all you have to do is transfer 3 (three) parts from the old original Fiero EGR solenoid and install on the new.

Below is the info and what needs to be done. First off, the part numbers.
Fiero Original (unicorn, good luck finding one):
ACDelco 214-361
GM 10038324

Near EXACT replacements:
ACDelco 214-303
GM 25519958
(Was available on MANY 80's GM vehicles, this post is gonna be about this one)
--->>>As of 6/11/2022: eBay, I currently see over 30 of them NOS. 7 under $120, and one seller has over 20 but cost $350+<<<--- Search both ACDelco and GM part numbers.
As far as junk yard pulls, these are compatible vehicles that you can probably get a decent one.


ACDelco 214-305
GM unknown
(Edit: GM 25519960
(Edit: Standard Motor Products VS5
--->>>As of 6/11/2022: eBay, I currently see over 20 of them. Price ranging from $65 - $140<<<---

(Same as above but includes sensor-switch/solenoid mount)


ACDelco 214-366
GM 14089438
Standard Motor Products VS16
(1985-1989 Pontiac Firebird and 1985-1989 Chevrolet Camaro, this one includes the jumper hose and the 3 inlet/outlet pipe setup just like on the Original Fiero EGR solenoid. This one is another unicorn and all you'd have to transfer to this one from the Fiero is the mount and air filter.)

Let's begin. This is just a minor how-to. Most other info can be found in these links (and others) already on the forum.
(CODE 32 answers. dialup warning pics)
(How I repaired my EGR Solenoid and eliminated my Code 32)
(EGR Solenoid Easy Economical Replacement)
So here's whats on 'My Plate'





























(These 2 pictures are from my old coil and metal housing)
PUSH the coil out of the metal case entirely by applying pressure to the shaft sticking out, just enough to have the plastic tabs exposed and seal. Then push back into the metal case.


Put the block-off metal disc and spring back in.

Now, when the electromagnet coil is installed in the metal case/housing, I'm willing to bet a special press was used at the factory to put equal amounts of pressure on all 8 metal tabs. I found that after I was putting this one back together the first time, I had a small leak when I used a section of silicone hose and blew into it and applied suction while plugging the other 2 using 2 fingers wearing a rubber glove. I would do this several times as I was bending the metal tabs. I found that by pinching them across from one another was best. Took me the usual, 3 times, taking off putting back on to get it right.


The other way, I would always get a minor leak somewhere around the seal or where the 3 pipe adapter mates onto the solenoid housing.















I've been known to over-think things from time to time, but It's EXTREMELY advised to waterproof and seal this as you reassemble. In other PFF threads related to CODE-32 some have PLASTI-DIPPED theirs instead of using 3M Weatherstrip Adhesive or silicone RTV. I didn't have any PLASTI-DIP, so I used what I had. When I repaired my original EGR solenoid 6 years ago, I see where I went wrong and why it started getting more rusty then it was when I first took it apart. Originally I only put sealant where (1) The 2 wires go into the metal housing to the coil (2) Around the metal housing where the air-filter dead-stops and the wires come out under the plastic hump (3) All around the square of the sensor/switch/filter (4) Where the 2 wires go into the sensor/switch/filter enclosure. This go around I added sealant to go around where the coil goes into the metal case as shown in the pictures above (rusted inside metal coil housing picture).

Why GM decided to put this device directly below the coolant/thermostat house, I'll never know. From the vents above the battery (water), the engine coolant/thermostat housing )coolant/water), engine heat (plastic degradation/contraction), you should seal it some how.

Feel free to let me know of any errors, or other suggestions to contribute to this problematic component that may become extinct.
I'm no mechanic, just a guy who likes to tinker.

The point was to keep everything looking original without modification. Painting optional.

Thats what I believe. Functionality should be the primary objective. The slightly different look of using longer hoses and a T connection should not be a big deal.There is talk about preserving the original appearance but painting the unit a bright blue is not original.

Wow, just WOW.
Why do these solenoids die and fail?Water leaking in. Thermostat housing/cap drip/coolant spill. Rear deck vents throw water on the belt throwing more water on it (yes, some of us DO use our Fieros as daily drivers and not just wipe them with diapers so they get driven in rain and snow). It's mount location was a poor location. You will want to seal this new one up if you want LONG LASTING FUNCTIONALITY... and in the process use the old hardware ('Tee' and filter) if you don't have access to another "tee and hose extensions".

We all aren't gearheads and grease monkeys that have that extra stuff in our back pockets or garages.

I am just posting to confirm that this corrects error code 32. Plug and play...no mods. Toss the old one and plug in the new one. All sorted.
The car has had this stinking error since I bought it. I have tried a few different solenoids and it remained.
Shortly after the car warms up boom the light popped on.

I ordered the following from ebay:
OEM VS5 EGR NEW Valve Control Solenoid/Motor
$67.75
Interchange Part Number
214305, 25519960
BUICK CENTURY 1984-1985
BUICK ELECTRA 1985
OLDSMOBILE 98 1985
OLDSMOBILE CUTLASS CIERA 1984-1985
Thank you to the OP for letting us know!
