Suggestions for SLIM Electric Fan

[MoabB2]

No way a 28" fan will fit on a 19" high radiator. Maybe some shrouding and it will fit widthwise.

My first thought was "What the hell?????"

Then I went back and looked at your original post. My bad. I thought you had a stock Explorer radiator and that fan could be made to work well. Not the case with yours...sorry.

HMM, this is all I found at Summit: http://store.summitracing.com/egnse...9+4294907005+115+4294838842&Ntk=KeywordSearch

This is the correct Summit page: http://store.summitracing.com/partdetail.asp?autofilter=1&part=FLX-365&N=700+115&autoview=sku

Nearly half the price as the one on Amazon

Only problem with that fan set up is it just doesn't flow any air.

i would just run two of these they are 12" and flow 1600cfm and are 2.5"deep.i run there 7"one and its a good fan and for $30 i can buy 6 of them for the price of those other fans!!

After tinkering around with it this week it looks like my fan is still working. It comes on when the AC is engaged and runs just fine. So, it must be the thermostat that is messed up because the fan isn't coming on when the coolant heats up.

I still need to upgrade the fan at some point though, as it is a weak link out on the trail. I always have to stop and cool down.

I'm leaning towards this fan right now: http://www.thehoffmangroup.com/autoloc/details.lasso?itemid=ZFU16S

yea they are good fans also I run there 3000cfm crome they are on ebay for around a 100 bucks but both fans are close to 4" deep tho and thought you had to have something less than 3"

Well, if you are going to go that route, why not this one:

http://www.derale.com/17-inch-rad-fan.html

It's much thinner. But I'm not crazy about any fan set up that isn't shrouded. Maybe these types of fans without a shroud will work just fine.

I think I can make it work. On the spec sheet it says it is 3.5" deep. With some creative mounting I think it will work. The one I have now (which is rubbing pretty bad) is 4.25" deep.

That one only pulls 2400 CFM. So if I can squeeze in a 3.5" deep fan, which I think I can, it will be worth the extra 1230 CFM. Shrouded is the better way to go but if you mount the efan correctly it should do ok.

I've limped along for 2 years now with the 1300 CFM fan, I am hoping that a fan with nearly 3 times that will help me considerably and get rid of my cooling problems.

I decided I'm calling these guys:

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=200195969149

It's U.S. Radiator and they have a store here in Phoenix. They will custom build anything you want. They will build it to fit the radiator perfectly. Spal has a fan that flows 3000 cfm that will screw to it and the whole thing is less than 3.5" if I recall. I may also have them build one for two fans. It can be thicker that way if necessary as I can leave a gap between two 12" fans that the water pump shaft will fit in. But hey...anyway you look at it...a full shroud for around $100 is a heck of a bargain as far as I'm concerned. I'd spend that much in factory shrouds I ruined just trying to adapt one!

 

[CDW6212R]

So you are looking at a 3" fan top bolt to the shroud, 1/2" thick? That may be one of just a couple of choices. The 16" fan or 17" fan linked to above would do well except in a really hot combination.

 

[Cobraguy]

So Don, you're thinking that the 16" or 17" single fan in a shroud like that won't handle the weather here in Phoenix? We're talking at least 3000 CFM here. Anyway, I wouldn't buy a fan that was less than that. I would rather go single fan over dual fans because the duals would be at 100% all the time in the summer. I turn my a/c on in April and it never gets turned off until sometime in November. When the a/c is on, all fans go to 100%. I already have a small auxiliary pusher in front of the condenser.

 

[CDW6212R]

I agree with you completely. I will avoid two fans for the same reason. If the CFM is really going to be close to 3000, that should work. I have really enjoyed the almost silence of my V6 truck, the fan runs so slowly and quietly when it does. A smaller fan or two would be much more noticeable.

My 99 SOHC truck and it's fan operation has been extremely impressive. My fan runs very very rarely. The radiator does an amazing job of cooling. When my fan does run, it's only briefly, and slowly. I probably have 25-35% power going to my fan when it runs, and it only takes say 10-20 seconds to bring the temps back under 190. I see a high of about 197-206 each day, my Scangauge records the highs.

The V6 and V8 radiators are almost identical in size, close enough to equate their performance. I have had other issues with the power circuit breaker, and inadequate antifreeze. I want a different fan than a used Volvo fan this time.

A shroud would be very nice. But with the limited space, I think that the effectiveness of a 1/2" shroud is almost insignificant compared to no shroud. That thin of a shroud will be a restriction to airflow in the non fan areas, compared to no shroud at all. Does that make sense? How much air would go through the "corners" naturally without a shroud, versus having to turn 90 degrees to go to the fan. At any speed the shroud would not be good. Only at a complete stop would the shroud help at all.

If you think that you would be stopped for five minutes at a time, the shroud should be good insurance. We get to the high 90's here for weeks at a time, so I understand how hot it can get. It may come down to another test. 1000's of people have tested random things in Mustangs, but no one ever documents factors and before and after results. We'd like to be able to use other tests, but there really aren't any.

Interesting ideas Don on the shroud vs no shroud theory. One thing about that...with the shroud I'm looking at, it would be very simple to try it each way. Another thought I had was to take a factory shroud, turn the electric fan around so the motor faces the radiator, and make it a pusher, then mount it in the stock shroud opening. That opening is too large, so some sort or mounting system would need to be engineered. I actually talked to Spal tech support about this and they thought it was an interesting concept. Normally, they don't like pusher set ups. But for no more than $100, I think I'll look at one of those aluminum shrouds and give it a try.

Edit: By the way...have you noticed the fan/shroud combinations you can buy from Spal, Derale, etc. all have flapper valves in the shrouds in addition to the fan(s)? They all allow air to bypass the fan. Think that has something to do with your theory of not being able to move air past the corners with a short shroud?

 

[CDW6212R]

Yes, even someone here did that on his own custom shroud. Or he bought it that way.

My epoxying of the used Volvo fan three years ago did work, but it didn't hold 100%. I had it off doing the WP and thermostat six months later, and needed to add more epoxy to make it better. I cannot see the seams, the epoxy is internal to the shroud. It doesn;t vibrate or move at all. I figured that if I built another similar to that, I'd use a minimum of epoxy to hold it in place. Then go over the seams thoroughly with fiberglass.

Bolts and brackets are great, but they don't work well on plastic, which is what most fans and shrouds are made of.

I'm new to the forum, but I have got some great ideas in the past from reading here, so I figured I would try and contribute.

I am working on finding an e-fan that will fit my 97 5.0. My initial thinking is that I will go with a dual fan to avoid clearance issues with the pump shaft. What do you think about this model from summit? It will only leave less than 1" exposure on all sides of the 19x24" rad. CFM appears to be sufficient and only 22 amps.

[Cobraguy]

That will be 22 amps EACH I'm sure. And you really want to avoid straight blades and go with something a little quieter.

This still works great even in the heat of AZ.

Any chance you can add another cooler/radiator to your setup? Seems like that might help?

 

[Turdle]

Just for reference-ditch the 7" dual idea-as I have 2 7" for just my 2 trans coolers. It is adequate for this application, but for your radiator you need way over 3000 cfm

 

[Fabbed4d88]

Couldn't you use this with the stock shroud??
