Factory Air Horn ???

[Bowman85merc]

Hey, I got this air horn from a 1989 Lincoln Mark 7 Designer Series. How it was mounted, it looked factory, or was a professional install. It even says FORD on the top of the horns, it also has a resivor type thing that connects to the horn, i dont know what it is, but it has a rubber bladder thing inside and somehow regulates air, im guessing. It also had hoses runnin under the mark 7's air box going somewhere, and hoses going into the driver side fender going somewhere.


But has anyone ever seen one of these ??? And could you explain to me how it would be hooked up, where the car is at, it is very hard to get to and get an in depth look at everything.


Thanks.

usually all you do with an air horn is feed air to the hose barb. No idea what that regulator thing is, unless its just a simple pressure relief setup. That would make sense, if you over-pressure an air horn it blows the diaphragms out. Never seen a stock air horn on a Lincoln though. I do know the guy to ask about it, oldschool1 either on here or on the mark vii club forums. Shoot him a PM, if anyone knows wierdo stock Mark accessories, he's the guy.

Cadillacs had em stock in da 70's

that regulator almost looks like one used on propane forklifts. (it lowers the pressure so that the engine gets propane gas, and not the liquid.) I wonder if this wasn't originally a propane conversion, or maybe even a fleet car. It would be a simple matter to tie into the system and use propane to honk the horns, but I wouldn't advise any long honks while sitting still. LOL

Hi Guys

The regulator looking device isn't a gizmos that can make air pressure using manifold vacuum is it?

OOh, that is an idea that never occurred to me.
It wouldn't be practical for large volumes of air, bit it would be fine for short bursts...

Thanks for the responses so far

Yea, my dad said it looked like a propane regulator too lol. That would be cool, I could see it being used as a fleet car for something, it has every option you could think of. But I dont think i would hook it up tho if it ran off of propane lol.

But how would it make air pressure off of vaccum ??? That just sounds confusing lol

We were also thinking that it might get pressure off of the smog pump maybe ??? I will just have to try and get a better look at it later this week when i go back.

Thanks.

I would have thought it would get it's air pressure from the air-ride pump.
........But honestly I really have no idea if that is feasable or not.

[gadget73]

that would probably involve a fair bit of messing with the air suspension compressor to feed a horn. I kind of doubt they'd connect the two systems.

Nice Find.

Sweet find!
This is news to me!

Even with the FORD plate, I'd have to say dealer or aftermarket install. The stamping doesn't ring true of Ford but I've been fooled before. I haven't gone through ALL of the Club's 88-89 material, but so far, nothing that says 'optional horn' has surfaced.

I'm no mechanic by a long shot but it's safe to say that it wasn't powered by the suspension compressor; too many safety issues to overcome. Vacuum powered? very possible to suck air through something to produce power/energy/friction/water ice whatever.

Someone should come up with an answer to this. It's way too unique. Also, 1989 had an LSC and a Bill Blass (designer series). It was probable a Southern car. Can you shoot the VCL in the driver's side door frame?

Again, nice find!

Ok, went to the junkyard again today, and its a 1987 Designer Series, not a '89.

And trying to trace all of the hoses just gave me a big headache haha.

But, I accually think this might run off of the Smog pump now, There is one hose that goes from the smog pump, under the intake, and then to this cunjunction of Tee's on the drivers side firewall, and then from that, there is a copper hose that goes somewhere down the tranny tunnel. And another that goes to somwhere under the brake booster thing.
Then there are these yellow hoses that connected to the horn and regulator thing, that go into the fender, but I couldnt trace those down since the car was in an extreme front end wreck and is all mangled.

But enough rambling, here are the pics, hopefully someone can identify this, and how it works.


Thanks.

Its an 86 not an 87 or 89. lol

What a mess of vacuum lines.

Nope, its a 1987...It was made late in '86 tho

But yea, the lines are everywhere lol.

Interesting because it has the 86 intake plenum plaque. Guess just getting rid of all of the old parts.

Thats an 87 LSC with 88-89 wheels, not a designer series. Possible it had some dealer-added "Designer Series" badging added when the cloth top was put on though, but that guy left the factory as an LSC. Officially, "designer series" was the generic term that covers the Bill Blass, and Gianni Versaci models. You can see the remains of the LSC fender emblem up front. It does have the correct 86-87 200 hp E6 headed HO engine intake plate. The 225 hp E7 engine has the other plenum plate, and showed up in the Mark VII in 1988. Grab that if you think of it, its the one that doesn't look retarded when you do an HO swap and want the plate.

Some of those lines are stock. The line to the smog pump with it's check valve thats laying on top of the intake is original, though not quite in the right spot. What its supposed to do is pull vacuum for the cruise servo under low engine vacuum conditions. Cruise servo is in the driver's side fender, which is why the bundle of hoses goes there. One of those white plastic tees is probably correct. The one with the hard line is not original, and I have no idea what that does. If I had to lay a bet on it, it goes to a vacuum solenoid that is controlled by the switch installed on the dash. FLipping the switch opens the solenoid, and you get vacuum to the air horn. Unless it goes to a vacuum powered air compressor of sorts, and you get air to the air horn.
