Just a note about the circuit thsat AndyR has shown. That is a Bosch relay that is rated at 30 amps. If you run two large fans, you will probably exceed 30 amps, so you would need separate relays or different relay capable of handling more current.

I tried twin 14" fans off a V8 Ford. They were 8 blade, 'S' shaped blades, & turned at 2300 rpm, pulled close to 40 amps. They did NOT cool as well as my trusty Pontiac Ram Air 7 blade flex fan, so they are now gathering dust!

If you decide to go "new", check out the new Flex-a-lite "180" series. I just put one on my '67 Firebird. It works GREAT! I installed it in conjunction with a CSI electric water pump.

With both of those, my motor temperature has not gone over 178. Sitting at a traffic light, the temp stays right at 160 (thermostat setting).

The fan comes with an adjustable relay/thermostat unit, and is also shrouded. It is rated at 3330cfm.

Lee,could I see some pics of the install?I'm thinking about going that route in my 69,was it a hassle or a simple install??

[Lee]

I'll try to remember to post some pics this evening, when I get home. I may have to work over today, so it may be tomorrow before I can do so.

The fan came with a nice selection of brackets. They are "universal", though, and not specific to any car. I was able to modify them without too much effort, to make them fit (IMHO) fairly neatly.

MY dual electric fan install cause the Alternator to go nuclear...and ran for 10minutes after car was shut-off.

I use the GM flex, or now the Flex-A-Lite Stainless repro Mechanical fan. HIS

To add to what Geoff said, I probably should have put that in there. Gm F-bodies especially, have a great relay on theirs. It is gray and oval shape and about 2 times the size of a Bosch and is rated alot higher than a standard ISO. I use them and no problems at all. (They were designed for a dual fan set up )

[Half-Inch Stud]

Use FORD or GM relays for best results.

Schoust, my ISP for the home computer is having problems. It may be a few days before I can get the pics posted - sorry.

Lee

[Schoust]

No problem Lee thats just another project I have been tossing around....

Don't mean to hijack, but what amp alternator do you need if you want to run the dual fan setup? I think that mine is 94 amps (12SI).

[onetru462]

That should be plenty of alternator for the car. Just remeber to use a good relay and keep the power wire from the battery is good sized and short as you can. Just don't use a harness feed for the relay.

Here is a pic that shows the CSI waterpump, the fan assembly, and the relocated alternator. Note that my car has manual steering (as God intended, for MEN's cars).

The top (driver's side) upper shroud bracket is stock, the left one I trimmed down. I've since trimmed both (and the lower ones) and neatened them up. There is another bracket that connects the long brackets to the shroud itself. If you look closely, you can see that I redrilled this other bracket's mounting holes. This moved it over enough to allow me to use the existing bolt mounts on the core support (I had to use bolts that were about 1/4" longer).

Hey Lee you got enough blue silicone on that pump??? :P A nice even light coat works just as good hehehehe. Just jiving ya man, I like the fan set up. Hows that pump do on the street?

I'll have to post another picture, with everything neatened up

The pump works VERY well on the street. In traffic/low-speed/idling situations, it works MUCH better than the mechanical pump.

I finally got around to installing my '95 New Yorker fans on my 'Bird today. A little more work than I thought it would be. I had to do very minor trimming on the corners of the shroud to get it on the radiator nicely, and made some brackets that mount to the rad. support the same way that the radiator does.

I ran each fan on a seperate relay and switch so I can run them independently. I also used 2-way rocker switches - up is "on", middle is "off", and down will "on" and ran through a coolant temp. switch (temp switch will be installed later).

I thought that those were a race only item?Hmmm

[geekwagon]

how do you get the fan on in front of radiator on non-engine side? I have no room on my 67 wagon as there is a tranny cooler there. Engine side has factory blade fan on the pulley. I guess i would have to ditch this and get new pulley bolts? If so what size?

[LouisianaGuy]

Nice install chicken, going to call around and see what I can find tomorrow
