secondary parts sourcing

[Brian Smith]

I am in the process of troubleshooting the vacuum control system for my secondaries. As is they remain (predictably) in the open postion. I have traced the vacuum hoses and they all appear to be in good shape (although I will probably replace them all as they show age). I am assuming I will be dealing with a problem with the vacuum accumulator canister or the secondary control solenoid. I will begin by replacing the accumulator canister as it has a slight rattle when shaken. Now that I have convinced the reader that I have used the search funtion... Does anyone have a suggestion for sourcing the canister or solenoid? I have the feeling that these are a couple of parts which, once explained to a Napa/autozone/advanced auto guru, will get me a confused, "...uhhh...i think thats gonna probably be a dealer only part..." Mabey it is, I dont know. Where have you all sourced these parts? Thanks for interest/replies.

I had this exact problem and solved it by replacing the secondary control solenoid. I had to order it from ford and it cost about 35 bucks. I replaced it in the parking lot of the dealership just to make sure it was what I needed and sure enough it fixed it. Turns out that when I gave the part number to any discount parts store (Napa, Autozone, Advance) it didn't show up in any of their catalogs. The guy at Napa called the parts guy at the ford dealer and they crossreferenced it and apparently, it's the same part for the 96-99 SHOs too. I don't think there is anything inside the vacuum canister that would malfunction. Order a new solenoid, if it doesn't work, at least you've narrowed it down. There's really only 3 things that could go bad with the secondaries: air leaks due to holes or gaps in the hoses or intake manifold, dead solenoid, or possibly somthing in that canister. BTW, I also determined that it was the solenoid because before it was completely gone, I would open the hood and shake it and it would close the secondaries. After a week or two, that didn't work anymore.

Good Luck,

Paul

Yes, it has turned out to be she solenoid. Although the canister rattles it appears to be functioning normally. I gave the solenoid a shake and the secondaries closed. This is a good thing, because apparently the canisters have been discontinued!

The vacuum canister houses a one way valve and a filter. The little cloth filter fabric is held on by a little ring that usually breaks off.

Since it is a one way valve, there is only one way to hook it up and have it work properly.

The raised nubs on the center ring of the canister go toward the plenum, not the firewall. You will hear and feel the nubs snap into place on the spring clamp if you have it right.

Glad I could help you out again Brian. I seem to keep having the same problems that you end up having a couple months later. Again, the dealer was the only place I found the part, but check with Torrie at FordPartsNetwork because I'm sure he could get it for you. The current part number for it is E8AE-9H465-BA but you'll have to send a parts request to him so he can look it up because it doesn't show up in the catalog. Good luck,

Paul

E8AE-9H465-BA

hmm, wonder what is was used on in 1988 and why it was revised ....

This is the new part number that the guy at the dealership gave me and said that it is the part for the 96+ sho's and that it was the part number that replaced the 93 part numer I had.

im not doubting or arguing with you, but ...

according to Fords part number categorizing, part number E8AE-9H465-BA equates to E8 = 1988, A = Full Size Ford, E = Engine/Powertrain department, 9xxx = fuel related category, BA = revised edition number 27. X is not used for revision numbers as some Ford parts were experimental and given the classification of X revision(mostly, but not often found, during the 60s).

SO..if you swallowed that, the part number could be found on, at least, a 1988 full size Ford truck, on the engine for fuel control related use.

if you think Ford part number decoding is difficult, try MoPar.

I'm not totally sure about it, but that's what it reads on the part that I installed in my car. It works perfectly and opens the secondaries at the exact same rpms as the old one.

Thanks! Armed with that part number it should be easier to deal with the ford dealerships around here.
