What's the deal with the Taurus / Mk VIII fan?

[T. Jerman]

About a month or so ago somebody posted some facts and measurments of a electric cooling fan from a Ford car. It put out like 4200 cfm and like a dual stage cfm fan. I cant remember what but if you have this information would you please post it again. Thanks :)

MODERATOR NOTE: All the questions and answers to Taurus/Mk VIII fans, relays and wiring have been merged and posted in this thread ~ Paul W.

[Shane65]

Here's a link to some info for those fans. A lot of current to start them but it gives plenty draw.

[nova65ss]

I tried one of those Lincoln fans in my 65 and it was too deep to fit. If it was offset to one side it would of cleared. Seems like it was almost 5 inches deep and it was hitting the water pump.

[T. Jerman]

Shane or anybody,

If i was to go a salvage yard to get one of these fans what years of Lincoln Mark VIII would i as for. Thanks again.

[63SSRagtop]

Unless my memory is failing someone had mentioned using a setup off a taurus that didnt require much 'adjusting'

[Shane65]

This might be one. If it is and you win the bid, it can be delivered right to your door.

[VonSwanko]

Now that the weather is warming up its time to think about my cooling system on my 67 Sedan.

I was thinking about an electric fan but...Theres not much room between my water pump and Rad.(about 4 inches).

What are you guys running for fans and such?I think my mechanical fan is a derale but not sure.And I have a cross flow rad from some other car but its the same dimension as a stock 4 row..

Thanks Rob

[Mike Goble]

I use a Taurus fan, a short Edelbrock water pump and a Summit generic aluminum radiator on the Durango Deuce. It never gets hot, even after 20 km of hard running at 8000 ft.

[new2novas]

i have about the same setup as mike, minus the edelbrock pump....i will have to second that combo, the taurus fan is a beast

[VonSwanko]

I have a long water pump which I am sure makes a difference.How thick is the Tarus fan and what year?

Rob

[Mike Goble]

The main sources of Taurus fans are the late 80's-early 90's 3.8L V-6 cars. It's about 5" thick and will clear a short water pump easily. In my 66 I have a 5-core brass radiator with a Taurus fan on it and it clears the water pump nicely.

[SuperNova69]

Hey guys, this is for all the people that use Taurus fans. I'm just wondering if they used the same fan for 3.0's and 3.8's, or if they each got their own fan?

Also, how big are they? My radiator core is about 22x19 if i remember correctly.

Thanks.

Matt

[SuperNova69]

Wow, thanks. That was asked just last month, too. Sorry about not searching.

Any idea on if a 3.0 fan is the same as a 3.8? I can pick one up dirt cheap, and I'd like to ditch the mechanical since it takes forever to warm up (especially at night, and I work the midnight shift, so that's really bad).

Thanks.

Matt

[chevy2ss]

i havent done this on my nova but i have done it on my cj5. has to be a 3 wire from a 3.8 if you want the high cfm.
heres a pretty good link

[MELUVNOVA]

Has anybody used the Taurus fan with a long pump? I picked one up today at u pull it, Im really not sure if it will fit..... I guess I could have measured clearance first :o but wheres the fun in that?

[wskaiser]

I think you are refering to the electric fan from a Taurus. It should fit even with the long pump.

[MELUVNOVA]

Well I went and tried it. With the Summit rad and a long pump it wont fit. I guess I will have to figure something else out.......Any recommendations for a wrecking yard electric fan that I can trust to keep a 400 sb with ac cool? Ive already got the rad and high flow waterpump covered.

[wskaiser]

I am curious what year Taurus you got the fan from. I thought most late 80s early 90s fans would clear.

[DriveWFO]

I'm pretty sure Mike Goble is running the Ford Taurus electric fan. Give him a shout.

[Mike Goble]

What kind of car do you have?

[wht73]

I just installed the lincoln mk 8 fan on a summit alum rad and it has about a 1/2" clearance to the waterpump. I installed it upside down so the mtr is to the drivers side.I think the taurus fan is the same .BTW my car is a 73 .

[MELUVNOVA]

Mines a 65. Im not sure what year the fan is from, the part number on it is E8DE8146AB. I found it in the trunk of a 89 taurus with a 3.8 It does look kinda different from the ones I see listed on ebay. Im starting to think that the one ive got maybe off of something else. Ive got pics, but I dont know how to post them. :o

[Mike Goble]

You'll need a short water pump to fit a Taurus fan in a 65. We have about 1/2" clearance between the short Edelbrock pump and Taurus fan in the 64.

[Lethal Injection]

I really like my flexilite dual fan set-up on the 67. They are about 190.00 but I have no complaints.

[SuperNova69]

Didn't read the other posts, but I've got the Taurus fan on my PHR aluminum radiator (thicker than stock radiator) with a Stewart Stage II long water pump. There's about a 1/4" clearance, but I'm not worried as I knew it would be tight.

Ah, just read the other posts. Sorry it didn't fit for ya.

Matt

[63IIPost]

For the guy that asked about the 3.0 vs 3.8, out here in Cali they have the big fans on the 3.0 wagon taurus, I just got one off a 95 wagon, 3 wire unit and I trimmed it and it fits and cools very well. These fans are 2 speeds, I tried the slow speed wire and it cooled fine today in stop and go in 90 degree weather, it ran about 190 on the slow speed stopped in the sun, and it ran about 170 with the high speed on, but the high speed pulled too much current for my 30amp relay, so im leaving it on the slow speed since it cools very well. I use a Howe radiator 18x22 core, email me if you need pics. Thanks

[SuperNova69]

That's good to hear. I don't know how to get the high speed (or maybe I have the high speed and can't get the low?). There's just too much wiring for me, but there's two 40 amp relays and an inline fuse for the manual switch, and the wires are really well connected. They've all been soldered and have shrink tubing on them, so I'm pretty sure everything is wired up correctly (especially since when I turn on the switch, the fan comes on). Maybe I'll post back the wiring setup and see if I can figure out how to get two speeds.

Thanks for the help.

As I recall (just put mine in last weekend) the fat blue wire is the high speed circuit, and the black/red thinner wire is the slow speed, and the big black wire is the ground. And mine came with 2 circuit brakers that are mounted on the fan, one a 20amp the other a 40 amp 20amp being the low speed, and 40 being the high speed. Be careful with the high speed circuit, you may want to run a 70amp relay direct off your alternator BAT terminal (make sure it's a mega amp alt as wel, I have a 130 amp one) to feed the high speed circuit, it really pulls the amps, and even fried a 10 guage wire on mine, so I need to run a high amp relay direct to save the wiring, and the fan comes with 8 ga wire for the high speed circuit so I would run 8 ga straight to the relay then fan to be safe, those suckers pull some major amps, but they work very well! And the Taurus has a high amp relay if you can grab it with the fan, they mount it right above the fan from what I could tell, oh and they have that nasty F word on them so keep some black paint handy.. lol Later

[SuperNova69]

Guess I'll have to go look at the wiring then. I got mine off eBay and it came pre-wired to two 40 amp Bosch relays. It had tags on each wire saying where it went, so I just hooked it up according to the "directions" and so far it works when I flip the switch.

I'd really like to know if I'm getting the low or high speed, though...it's driving me mad... :D

Guess I'll go out there today since I don't really have anything better to do. :D

Thanks.

[Chris67Wagon]

Mike I researched the Topaz switch, they have one at Advance Auto Parts part # TSU 83 for a 92 Topaz 3.0 didn't have info. on what temp it was, has a 2 pin connector. What do you think??? is this the one??? Thanks; Chris

[Mike Goble]

The one I used was off a mid-80's Topaz and actuates at about 205°. I don't recall the exact number, but some stores have catalogs of their switches that show the actuating points. I'm in Portland right now and don't have access to my usual sources. I think I kept the box it came in so I could get another one.
If you have one already, put it in some hot water and test the actuation point. If it fits what you want to do and will screw into your sensor location, hook it up.

[Chris67Wagon]

I checked back at Advance Auto's web site and its the same switch for the 85 Topaz too...Might just be the one......Thanks Mike; ..Chris

[strtlegal]

im switching a bunch of things on my nova and have had okay luck with permacool's 1900 cfm fan..i used an original 1970 nova fan shroud but have a 31x19 griffin aluminum radiator instead of the stock 27x19 radiator..im not sure if im pulling enough over the rad cores so i was thinking of purchasing something bigger....

what have you guys had luck with..cfm? dual or single fan? and does it come with a shroud?? please any help would be great

car is: 1970 nova, sbc, no a/c, and arizona heat!

thx.strt

[MaitlandTron]

I am using a Flexalite 12" part number FLX-110. Its attached directly to the stock radiator and no shroud. Seems pretty small to cool a mild 350 but it nevers gets above 185 at a standstill. And keeps at 170 while cruising. And its been a constant 110 outside here in phoenix.

[Mike Goble]

We use a Ford Taurus fan off a 3.8l engine, a 2-speed fan that moves a ton of air.

[strtlegal]

ive heard of that before but if i want one i have to find them in a junk yard.new from ford has been discountinued

i work for dodge and we have been selling the viper fan modules.a local shop has been using them on turbo cars and they say they work great..but not sure if i wanted to go that route..

im still all ears!

[Chris67Wagon]

I have just finished installing the Taurus fan in my 67 wagon.(short water pump) I used the universal Summitt Alum. Rad.. To mount the fan to the rad. I made (2) metal tabs at the bottom to fit into molded indentions of the fan shroud and did the same at the top, real easy. Used the $17.00 fan controler from Flex a lite or Hayden (can't remember) and bosch relays..2 for low speed and 2 for high speed..Have not road tested yet, but in the garage works great...Also if you don't want to go the junk yard route, check Ebay....Chris

Greg,

It looks just like mine.

Paul,

You find them on late 80's and early 90's 3.8l Ford Taurus and Mercury Sable cars. I think they're about 17 x 22, fit perfectly on an early Nova.

[72Orange]

A lot of the guys at Team Chevelle are using a two fan Ford Windstar module. One fan runs full speed all the time, and the second can be wired to do the same, or run at a slow speed or a high speed depending on the engine temperature. They swear by it.

[63AKDN]

I just picked up a couple of fans for $50CDN. One came out of a 3.8L, and the other was in a 3.0L. They had 5 or 6 Tauri (plural for Taurus???) in their yard and one of the 3.0L had the big fan, but all the others had the small one. With my luck the one I install will blow up or get damaged somehow so that's why I want a spare :D

Anyway, I took these badboys home and decided to take the fan off of one of them for something to do. I removed the metal clip........is that all that is required to allow the fan to be pulled off? It is quite rusty in that area and I have scraped and wire brushed around the shaft and gave it a little squirt of Releasall an hour or so ago.

Thank you in advance

[Necro]

sometimes those fans melt on the shaft.
be careful they are a balanced design. if you take more than one apart dont mix them up.

[63AKDN]

The plan was to take only the one apart to make it easier for cleaning, however I ended up cleaning one up quite well without taking the fan off. The one that did have the clip removed will need a new clip due to it being quite damaged during removal. That will be the spare one though.

Time to start collecting parts........short water pump and low alternator mount for starters, then I guess a couple new pulleys, and the necessary temperature switches, relays, controller.........I guess the install will be a winter project.

Sorry I missed this post. Thanks!! For a hundred bucks, it looks like a winner.

[tpinova]

Just thought I would mention something on a related note. Before my bodywork and paint were done, I drove my car for quite a while with no cowl panel. After the the cowl panel and hood insulation were installed, I noticed that the operating temperature went up noticably at idle. Years ago, I knew guys who used to drag race with the rear of the hood raised slightly higher than the cowl. They claimed it allowed hot air to escape and gave them slightly lowered their ETs. Really makes look at those cowl induction hoods differently.

[69bigblock]

Many people uses those fans. Taurus/sable from 91-95 3.8L. Also people use's them in conjuction with the http://www.dccontrol.com/

Somebody please tell me about electric cooling fans in lieu of the regular fan blades. What manufacture are you using? Where and how do you wire it. What size fan for a 75 Nova radiator?

Thanks

I use a flex-a-lite blackmagic 150 but i know a lot of people use lincoln mk4 electric fans

Do a forum search for 'taurus fan'. In the meantime, here are a couple of links:

You can get a new, repro Taurus fan on ebay for around $100. (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1,1&item=7972530455)


This post on a Bronco forum talks about the basic wiring, and the fan controller. (http://www.fullsizebronco.com/forum/showthread.php?t=40564)

Here's the best breakdown of it I've found yet. (http://www.fordmuscle.com/archives/2003/02/electricfan/index.shtml)

[tpinova]

First off I should say that there is not a electric fan out there with the reliability or life expectancy of a good mechanical fan. On a street car, I always recommend running mechanical fans if possible. They don't burnout or blow fuses. The engine you save maybe your own. That said, there are some applications that require an electric fan. One size does not fit all. A cooling system should be designed as a unit. First the radiator needs to be sized correctly for the engine. Next, a fan should be chosen based on displacement, horsepower, radiator dimensions, and the presence or absense of air conditioning.

I have an unusual air intake that would not clear a mechanical fan. I have a 350 with air conditioning. Due to the width of the factory radiator in my car, I could only run one 16" fan. I found that the car would get too hot at idle with AC running on a 100 degree Georgia day. I cured this by swapping the three row brass radiator to a single row aluminum radiator to increase air flow. The Perma-Cool 16" electric fan (2950 cfm/ PN: PRM-19115) is controled by a Hypertech Cooling Fan Switch (# HYP-4028) and a standard 30 amp relay. I don't like to mount a fan directly to a radiator because it causes leaks but it is important to get a good seal between the radiator and fan to maintain good airflow. This set up would not sufficently cool a larger engine but it works for my application.

I believe a '75 has a wider radiator so I would run two fans of the highest cfm available. And if somebody told you that changing from a clutch fan to an electric fan would make a huge performance improvement, they lied. If that's your goal, don't waste the money. These are the same people who say that power steering slows a car down. The truth is power steering only takes a 1/4 HP when the wheels are straight and 3 HP at full lock. It is pretty said if you aren't making enough power to sacrifice 1/4 HP.

[new2novas]

junkyard taurus fan woot!!! $6

[Mike Goble]

We use the Taurus fans on most of our cars, the reliability has been very good, replacement costs are minimal and there's a million of them out there. The one on our road racer has yet to turn itself on high speed.

[Greg_R_63]

Mike, which fan controller do you use?

-edit-

Nevermind, I found it here. (http://www.fordmuscle.com/archives/2003/02/electricfan/index.shtml)

[72Orange]

I use a 16" Summit electric fan which will probably need to be upgraded in a few months when I put my new motor in. I use aSPAL (http://www.spal-usa.com/html/dampframe.htm) kit that I got on eBay for about $50 to turn on the fan at 185 and off at 165. But I find that once the fan goes on it doesn't shut off because my themorstat is a 180 degree themostat. I'm thinking about getting the sender for on at 195 and off at 175 and getting a different thermostat. I guess I would want a 170 degree in that case, right?

Anyway, just a few things to think about.

[Mitchc]

I am looking for a timer/relay for my cooling fans. What I am having trouble with is on hot summer days my fan runs for so long when I come back sometimes the battery is very low..

I have a temp sensor in the right head that turns on the fan at 180 degrees and off at 170. I running a relay between the fan and the sensor, switch, and the ECM. All controls the fan. Well when the temp runs up to 210.. Well then the sensor wants to keep the fan running until the water gets down to 170.. So what I want to do is only let the fan run for about 2 or 3 minutes then shut off and let the engine cool down normally.. I thought about triggering the fan off a ing wire..

What do you guys think..

Mitch

[72Orange]

I have a similar setup for my electric fan. Once it gets up tp temp the fan almost never goes off. So I run the wire that goes to the sending unit through a switch, so I can shut the fan off whenever I want to.

I am also thinking about a new sender which will turn the fan off at a higher temp.

[tpinova]

I have my temperature sensor mounted in the intake manifold. The Perma-Cool 16" electric fan (2950 cfm/ PN: PRM-19115) is controled by a Hypertech Cooling Fan Switch (# HYP-4028) and a standard 30 amp relay. The fan is mounted to a aluminum radiator from a '86 Chevrolet G-Van that is intended for 4.3L V6. (It is a bolt in in a third gen Nova.) I also have a Ultima Battery. My fan will stay running after I get out of the car but I've had no problems with a drained battery. One thing you may want to check is for any air leaks between the fan and radiator. I don't like to mount a fan directly to a radiator because it has a tendancy to cause coolant leaks but it is important to get a good seal between the radiator and fan to maintain good airflow.
The ideal set up would probably be to have the sender in the radiator. That way the fan is only trying to cool the coolant in the radiator. When the water pump isn't turning, it's definitely not cooling the coolant in the engine.

[Custom Jim]

I'm going through the same with a customer with a 30's something Dodge truck. Our options are one of two things:

Wire the fan to an ignition source OR put the temperature sensor in the radiator.

If the temperature sensor is in the block and the engine is running the water is flowing past it and will or should work properly if designed correctly HOWEVER if you shut the motor off, what happens. The water flow stops and the engine block gets a little hotter. Now the cooling fan kicks on and cools the water in the radiator but cannot try and cool the water in the block where the temperature sensor is at since there is no water flow and if you are lucky and get it to work that way, great but the fan will only be blowing cooler air across the engine block until it can cool the water that is sitting in the motor and the temperature sensor will then turn the fan off.

On the customer of mine with the 30's Dodge he is ordering an adjustable sensor to go in the radiator and we will then take the signal wire off of the sensor in the block and connect it to that unit and then out of that unit run a wire to a ground. He could move the sensor from the block to the radiator however

On his it's more cost effective and less labor involved since the wiring for the fan cannot be easily changed from the battery to the ignition.

Jim

[BillsNogo]

I am looking at replacing my fans with a suggested Ford Taurus fan. I did a search on this site and could not find what years, what to look for why they are the hot ticket for electric fans, how much cfm they push, ect.

Can someone clue me in or give me a trail to follow?

thanks as always!!!

bill (clueless in minnesota, ya dontcha know!)

I did a quick search in the Electrical section on Taurus Fan and found quite a few threads.

Here's a link that might help:

Thank you Paul, I guess I should have done a more general search instead of a title only search :rolleyes:

It looks like for the price that I will give this fan a chance, but will need to upgrade my alternator. Oh the fun :)

[new2novas]

the deal is these fans rock...i got mine from a 96, maybe, taurus 3.8...cost 6 bucks at the junkyard, i shoulda picked up more when i was there :rolleyes:

[Rich_66]

Does any body have the measurments of this fan? Height, width, and thickness at its thickest part. Thanks Rich

[63AKDN]

Rich,
The shroud of the fan is about 15" X 24" and is about 5 1/2" deep.

[BillsNogo]

Rich,
The shroud of the fan is about 15" X 24" and is about 5 1/2" deep.
Bummer, I only have 3.25" from my radiator to the front of my water pump pulley. I even have a short water pump :(

which yards did you go to there used to be a great yard in willow grove lous on 611 but its gone now.

[Steve J.]

How about installing one as a pusher in front of the radiator, instead of as a puller?

[BillsNogo]

How about installing one as a pusher in front of the radiator, instead of as a puller?
I thought of that, but no more room in front either do to the hood latch support. I was thinking about a derale duel fan, would fit depth wise, but not width wise as my radiator is only 22" inbetween side tanks.

I have a few choices I am contempating right now.
1. Switch away from the march pulleys to the groove pulleys and see if the stock pulley will be shorter so I can fit another electric fan.
2. Add the groove pulleys, derale flex mechanical fan, small block shroud, add long water pump, move the alternator to the passengers side, might add power steering
3. Add big block frame mounts, Add the groove pulleys, derale flex mechanical fan, big block shroud, add long water pump, move the alternator to the passengers side, might add power steering, worry that will not fit under the hood (rpm air gap intake)

It just seems imenent that I need to ditch the march serpentine pulley system to cool the big block. sigh.........I guess I did want the more stock look anyways :o

[new2novas]

brownie, it used to be called lous u pull it or something like that....its now in levittown, can't remember if they still call it lou's or not but give it a try. Call first, i asked them if they had it and how much then shot down there and pulled it out...6 bucks woot!

[nova65ss]

I tried one when I had the sbc in my car with the original front clip and it didn't fit. Wasn't even close, it was too thick and hit the pulleys. How are you guys managing to get them in there?

Jimmy

[Greg_R_63]

Here is a pic of my old setup with a 2-core Howe radiator. Keep in mind that the chrome shroud is 5 1/2 to 5 3/4" deep:

http://www.nocturnaloner.net/Nova/eng1.jpg

It's hard for me to say how you don't have 4.85 inches of clearance with your setup, because I don't know what you have.

[SuperNova69]

I think there's different thicknesses then (or the different years had different thicknesses??) because there's just no way mine is 5" thick. It's less than that. It barely fits (in fact, the studs from the water pump pulley apparently were hitting and kind of wore a groove into the fan so they clear now :o ), but it fits, and it works. So I'm happy.

Matt

[Greg_R_63]

Remember, I'm just talking about the space I have between my radiator and fan pulley. Pro-Touring shows the total depth of the Taurus fan at 4.85 inches.

[SuperNova69]

I don't even think mine is that thick...maybe I should go measure...

Matt

[Pro-touring72]

Here is why I ask. I hooked mine up the way outlined in some posts and other sites. Low works fine then when i shift into second speed it does speed up but not as fast as it is with just the high speed hooked up and no low speed.
Should both pos+ wires see voltage on high like Ive seen or should it switch.... E,I low sees volts on low but not on high?

Like I said high speed rips when it only has voltage and no voltage to the low section..

[63AKDN]

According to what I've read, having voltage applied to both low and high speed leads simultaneously will lead to premature failure of the motor.

How is yours hooked up? I am in the process of wiring up a Taurus fan and went with two relays in parallel for each speed. When the low temperature relays close they supply power through the high speed relays (normally open contacts) to the low speed lead. When the high speed relays are activated, the power is then switched to the high speed lead through the other contact.

I have a wiring diagram that I drew up and managed to get a half decent picture of it with my digital camera (no scanner). Send me an email and I can then send the diagram your way if interested.

Hope this helps

[Mike Goble]

One relay is sufficient for the low speed winding, use a larger one for the high speed winding. You don't want to energize both at the same time. I use a relay to steer the control from low to high speed so only one at a time will energize.

[Pro-touring72]

Ok Im glad the people on this site are on the same page as me. It sounds as if my plan is the same as Mikes.

1 relay for speed one. One for controling high speed (75a) and one that will turn off activation circuit to low speed when high kicks on.

Granted that my engine builder is staunchly on the mechanical fan side of the fence, and the logic behind that choice is sound, I decided to take a chance on an ebay Lincoln Mark VIII fan, mostly because of all the good internet buzz about the big f*rd fans in general. Worth a shot to test it out, but I always have the option of re-selling it. Good thing is, the built in shroud is the exact dimensions of my radiator, fitting just inside the 19 x 22" core area, so it should be efficient. I found out only after bidding that this is the 93-96 fan, which turns at half the speed of the 97-98. Two questions:

Should this fan be adequate to cool a street driven 350, even if it's not the higher speed version?

Can I connect it directly to a battery to test it, or is a relay required? Sorry for my electrical ignorance.

[Paul Wright]

I merged most of the Taurus Mark VIII fan questions/answers (http://stevesnovasite.com/forums/showthread.php?t=24850) together and put them in Powertrain Best of Tech. section.

[63AKDN]

Excellent idea and great work Paul. There certainly has been a lot of buzz around these fans lately. That will make people research much easier.

[Greg_R_63]

Thanks Paul, that was much needed. However, I didn't quite find the specific answers I'm looking for. Most importantly, I need to make sure the fan works without frying it.

[Paul Wright]

Do a search on "taurus fan" in the electrical section. I'm not a moderator in this section so I can't merge the posts into Best of Tech. If baby deuce or joey T sends them over I can store them there.

[the FLYER]

Paul, Pm me if you like with the threads you'd like merged... i'll do it for ya... then you can edit to your desires


John :)

[Paul Wright]

the problem is I'm not as good of an electrical guru like Mike is. I did a search and there seemed to be lot's of good bits in various threads. I need someone to review and edit them and split them out of the home thread and into a new thread. Basically all the "how to wire in relays and sensors" posts and anything not already covered in Powertrain. Once they are all together then send them over.

[babydeuce]

I sent over all the relay stuff, but I did not find much on the fan. I screwed up and sent everything to performance, so you will have to move it around a bit. If you want anything else, just give me the thread name and I will move it over.

Jack


I just went and checked the performance section, I thought the move would put them on top, but instead it mixed the moved threads in with all the rest. I will copy them again into the best of tech section.

Double check this but is this better (idea's to modify it ?). I also moved the order of the relays so take that into mind when checking.

I had to revise the schematic to rectify a Back feeding issue. Feel free to compare fixed schematic to the one in Custom Jims post above...

I had to test a fan for Greg_R_63 a week or so ago and I had seen some replies about using a 75A relay I wanted to see what I could design or have as an idea for others. Below is what I made.
I ordered an 80A relay from one of my suppliers. I then modified an ANL fuse holder to make the assembly more one piece. The ANL fuse has had the ears bent at a 90 degree angle to make the assembly more compact. The ring terminals accept 8 gauge wire and the ANL fuses can be purchased in a 60A or 80A size. They also make larger ANL fuses but you don't want to fuse larger than what the relay can handle.

I have a 31x19 Griffin rad with the Flexalite dual fans they are shrouded and cover just about the entire core. The fans are slim and fit great. This setup cools my Big Block excellent. I highly recommend it if you don't want to go with the taurus fan.

[T. Jerman]

Has anyone put a Tauras fan on a stock 66 rad. According to the measurement I have I dont think it will fit. The rad. finn section on stock 66 rad. is 24 wide x 15 1/2 tall. Somewhere I got some measurements for Tauras fan and they were 24x19. The 19" part is going to be the problem. The inlet to my rad. is in the middle top and the outlet is lower pass. side. If anybody did use this fan on a 66 rad. did you have to do some trimming on the shroud to get it to fit.
I have located 2 of them and was going to install one this week while on vacation. So please let me know this would save me a trip to the salvage yard.
Thanks anyone!!!!!!!!!!!!!:chev:

If you use the block mounted temp switch,will it have to be a 2 wire sensor?

[Pro-touring72]

No the body of the sensor will do the work of grounding it.

[arndog]

awesome picture of the schematic. Does anybody have any part numbers for the relays? The two 40amps look like standard 5-10 dollar guys but the big one I don't know about. Im thinking of something to ask for when going to the not so good part stores. You know the ones where you need to tell them what kind of shoes you have on as well as if the rear windows are power in order to get an oil filter :D

arndog

[Pro-touring72]

Here are the relays I used. Bosch # 0 332 002 150 About $20 online Google the part number for many sources.

And this VIA-80238 $8 from summit racing. It makes for a cleaner install and is cheap You have to reconfigure the wiring in the connector but that is easy as pie if you have a small flathead screw driver.

I am thinking of going this route on mine and was wondering ? Do I need to replace my 80 amp alt? with a 130 amp? or more? Thanks Eric
