Thanks. I will cherish this bit of information forever.

Does anyone else have any feedback on fan noise that their electric fans make? Is it loud? Annoying? Not a problem?

I've been told that the 18 inch fan from a big ford product works great. The fan itself isn't made by ford, so it's ok to use.....Zoomy

BobbyK · 03-27-2003, 08:07 PM

Two 14" Perma-Cool fans mounted to a home made aluminium shroud.

In my 71 Blazer.

special70gmc · 03-27-2003, 09:17 PM

thats nice!

dubie · 03-27-2003, 09:23 PM

oooooooooooooohhhhh I want them for sure now

That setup is so SWEET!! How much did the fans cost?

spinning wheels · 03-28-2003, 01:48 AM

Perma cool sells a dual fan set up now. I'm lucky enough to talk to one of their old employees at the local swapmeets. I constantly picking his brain on cooler and setups. He sells scratch and dent stuff real cheap. This is stuff that they couldn't sell for full retail.
dubie, I will try to find a price on the dual fan setup, but just how soon do you want this setup? And, would you have to pay import tariff, if it was shipped to you?

BobbyK · 03-28-2003, 03:51 AM

Hey Dubie,if you want the set-up spinning wheels is talking about I can get it to you.I'll be leaving for Winnipeg April 8th.
If you want he can ship it to me and I can bring it across the border when I come to Winnipeg.

The Perm-Ccool fans cost me $83.95 each from Summit.Part# PRM-19114.They are rated at 2100-2900CFM.

I bought a Painless Wireng kit to wire it up $59.95,part# PRF-301102.After seeing it I could have wired it up myself.

The oly thing I would have bought is the thermostat that thread into the head.$32.95 Just for that.

Two 30 amp relays,two 30 amp self resetting circuit breakers or inline fuses and some 10-12 gauge wire.

The whole thing cost ME approx. $245 to put together.It can be done cheaper with junk yard parts though.

TERRYP · 03-28-2003, 04:45 PM

I've got the Ford Dual fan set-up in my 68 3/4, use a manual ac switch from a toyota to switch them. super power, at least 3x what I got from stock fan.

TERRYP · 03-28-2003, 04:54 PM

Here is the Ford set-up, drops right in. You even get the shelf for free!

HotRod929 · 03-28-2003, 05:57 PM

TERRYP - What kind of ford did you get those fans out of? Cre? Truck? Year? THanks

TERRYP, I hope you're going to replace that belt soon. It looks like it has seen better days

Kenneth

TERRYP · 03-29-2003, 06:50 AM

I think those fans are out of a full sized Taurus, you'll see they are right as soon as you look under a few Ford hoods. And that belt is one of those new ones with the notched outer belts, softer and less tension needed.

Blue Beard · 03-29-2003, 09:32 AM

I have one of those belts on my ride too....

Had a fellow make the same comment on mine..............

Phew... glad to hear that. I thought maybe you had seen my belts and decided to copy (mine are NOT the new notched ones

).

Kenneth

spinning wheels · 03-29-2003, 09:39 PM

Terry, did you upgrade your altenator? My understanding is that the fans take up a lot of amps. About 30 each, when they kick on.

TERRYP · 03-30-2003, 05:46 AM

Start-up load is high on all fans, but both are protected by a single 30 amp breaker, each has it's own relay. Toyota Tercel A/C switches are lighted when on, have 2 speeds (read as two fans) and are everywhere cheap at the yards

TERRYP · 03-30-2003, 05:50 AM

here is the fan switch. Upper right corner of dash

Low69CST · 04-12-2003, 02:09 PM

My flexalites are noticable, but not very loud, they keep my hopped up 400 cool sittin still. They are also sucking fans, I've been told thats better than fans that are infront and blow threw

**Classic Heartbeat** · 04-12-2003, 05:29 PM

Here is a duel 12" stainless steel set up that I sell. It is 4 3/4" deep (shallower onnce installed) Mine come complete with thourmustat included. The thermostat that screws into the head does absolutely no good. You are cooling the water in the radiator not the engine. And the electric fans are not blowing air across your engine, they are either designed to push or pull air through the radiator cooling the water in the process. I can give you an example... Let say the water temprature in the engine is 160 degrees and that is where you have your thermostat to kick the fans on at. The fans come on and start cooling the water in the radiator... That doesn't make sence... The water in the radiator is probably only 100 to 120 degrees anyway, because it has been cooling inside the radiator.... The engine water temprature will continue to climb untill the thermostat in the intake manifold relieces it, to circulate the hot water out of the engine, and into the radiator. This forces the cooled water in the radiator back into the engine, therefor cooling the engine. Now is when you want the fans to come on, because the water temprature in the radiator is now whatever your thermostat for the engine is set at and needs to be cooled by the fans that are mounted to the radiator. Make sence?? Anyway here is the picture..LOL WES www.ClassicHeartbeat.com

BobbyK · 04-14-2003, 12:48 AM

Ya you don't want the fans to start up before the engines thermostst has opened up.
I do have the thermostat threaded into the head.My engines thermostat opens at 185 F.,my thermostat that turns on the fans is rated at 200 F. on and turns them off at 185 F.
Works well for me.:p

sneakysnake · 04-14-2003, 09:56 AM

I used the fan out of a 81 chevy citation fit on a four core radiator with not much fab work, be sure to use a relay or when you try to kill your engene the fan acts like a generator and back feed your ignition till it slows down enough to stop producing electricity to run the truck.
