96 was not the first year the crown vic had the 4.6L At the prison I work at, we had a 94 crown vic with a 4.6L in it.

 

Yea WTD is right, 96 was the debut of the 4.6 in the Mustang. It had been in Fords, Mercs and Lincolns (4.6 DOHC) earlier than 96.

Whats the part # on that fan? I wonder how much it would be new...

Would (in your opinion) this be worth doing in a 4.2L ?

i've seen both CV and caprise patrol cars and they both have electric fans.
I wonder if the police interceptor package has a higher CFM fan compared to the "standard" CV?

 

That is good info everyone is posting. More cars to find a fan in!

For the police and standard units, I doubt it. Maybe different radiators but not fans.

 

As a matter of trivia:

The Romeo Modular made its debut in the 91 Town Car, and went into the rest of the full-size car line with the 92 redesign of the Crown Vic/ Grand Marquis. The initial versions were rated at 190 in single and 210 in dual exhaust tunes. Mustangs got the engine in 96 freshening, and the F150's with the 97 redesign. The 5.4 variant, along with the Windsor sub-flavor of the 4.6(numerous detail differences between the 2) came out late 97/early 98.

The electric fans were a 95-96 phase-in, on the 'Vics, and interestingly enough, was partly responsible for the lowered tow capacity rating of the full-size cars, as the electric fan doesn't pull quite as much air thru the rad as the engine driven fan. The fan from the cop car 'vics should do OK in most climates, but I'd be wary of it in a particularly hot climate with a heavy load, and towing in crawl-along traffic. With the V8's, we get the 130 amp alternator, so power should not be a big issue, but a motor of that capacity will draw significant juice, so watch the other accessories and electrical loads (trailer controllers and charging aux batteries in a crawl-along traffic come to mind).

 

Where can I buy a Hayden controller?

So replacing the regular fan with the electric one helps? Sorry if I sound a little dumb but how can it make such a difference? Do the factory fans really suck up that much power? Shouldn't you increase the amperage on your alternator? Also since the alternator will have to work harder will that make any changes?

I never understood that mod and the smaller pullies people rave about? I guess it has to be true if our existing fans uses clutches but do you really think it's worth it? I could go to a salvage yard and rig something up

Thanks

I couldn't find the Hayden control but did get a PermaCool adjustable w/AC from Jegs. Just got it this afternoon. It's setup to direct run a fan or duel's up to 20A & the sensor stabs in the radiator fins. pretty easy install. about $40.

I got the Hayden unit with a 30 amp relay and fuse at my local Knechts parts store.

For eph1fifty's questions, you are freeing the load on the engine and freeing up HP. Basically take a broom stick and spin it in your hands. Now add a 17" fan blade at the end of it and spin it. Which is harder to do? Same idea with the engine, but at 700rpms+.

If you want to test the idea, go rent a fan wrench at your local autozone, remove the shroud and the fan. Now drive around the block. That is the amount of power you will free up when removing the fan. You need to add the electric unit to cool the vehicle when there is not enough wind/air flowing thru the radiator to adequately cool the engine-- ie at low speeds.

The electric fan does not have to run all the time. You could wire it up that way, but not needed. You buy a controller that ONLY turns on the fan at a certain temperature setting or like when the AC is turned on. So like now in the winter, the fan NEVER comes on in normal driving here. In the summer it will come on about 50% of the time in city driving.

 

Good work, Matt! Excellent info. I put a flex-a-lite electric fan on my V6 a while ago, and it certainly increased the fuel mileage. With an automatic tranny, it is harder to feel a 'seat of the pants' increase in power, but no doubt there is some power gain.

How much the fuel mileage increased is hard to tell as I've done other mods and my mileage varies from tank to tank. FWIW, truck used to get about 16 mpg stock, now I usually get around 18 mpg with more miles on the engine, Superchip, and Airaid.

My estimate is the fan made the biggest improvement in mileage of all the mods - around 1 mpg or so. Also, the engine heats up much quicker on cold mornings.

Unless you regularly haul heavy loads in hot weather, an electric fan is a great idea for these trucks. If you do haul a lot in the hot, a more expensive double electric fan will still flow more air than the stocker.

Wow, that mod sounds awesome. My warranty is up this April, so I'm going to think about this mod.

Do you have any pictures of the install? Do you think an 18" fan would fit in the factory shroud?

Thanks.
