Electric Fan

[bidibronco]

Isn't there a sensor that can be put in the rad fins that will have a "pre set temp" to turn off and on an electric fan or am I just a wierd person? After I get this "new" engine done I want to get rid of the mechanical fan but I'm not sure what size fan(s) I should get or how to turn them on and off without "inconviniancing myself" with switches? Anyone know what I'm talking about?

Yup, your right. I havent used one in a while, but any performance shop should have exactly what your looking for. Last one I used was for my 455ci buick, and i never had a problem with it.

SeaBronc did a great writeup about electric fans with pictures and everything less than a month ago.

I've never seen one that fit into the fins, but I'm guessing that's because it wouldn't give you a very accurate reading. Most thermostat switches are NPT and thread into the radiator itself so that the sensor itself is surrounded by coolant and is reading an *actual* temperature.

Here's a few from Jeg's & The Fan Man. Knock yourself out my man.

If you can't find what you want at either of those two sites then you've got WAY too much time on your hands /emoticons/[email protected] 2x" width="20" height="20" />

I use thew Imperial 226204 control for my fan. I includes a relay, (which I use to control a heavy duty solinoid) and a temperature control. The probe is placed in the radiator fins right near the return hose, a small round disc is placed in front of the probe so it will read true temperature and not be affected by air moving through the radiator, (part of the installation materials).

A couple of picture to aid in visualization of what I wrote above. #1 Original installation, #2 A schematic, #3 in it's new location after relocating battery to the back of the truck, #4 In it's new location with cover, #5 The probe installation.

Good luck,

I have also seen electric fans that use a copper style probe that is fed down into the water inlet and then the radiator hose is just slipped over it and tightened down as usual. I have never personally used one as it seems to me that there would be problems with getting the hose clamp tight enough for a water tight seal.

Aw, hey. Look at that. The $hit we learn about every day /emoticons/[email protected] 2x" width="20" height="20" /> I guess it makes sense as long as the temp you measure is absolute and you make allowances for the difference in how it's measured.

EvlFaust: I can see that working. The hose is fairly pliable and as long as the wire for the thermocouple isn't freaking huge then the hose itself should be able to seal around it. I'd probably use some silicone all around the gooseneck just to be sure it sealed OK but I wouldn't expect *too* many problems from a system like that either. It's just that all the one's I've ever seen have nbeen threaded NPT to use a port on the radiator, but I suppose it stands to reason that some Rads don't have an access port so you'd be forced to use something fin mounted or an in-stream thermocouple. Freaking cool guys, I love seeing $hit I haven't seen before.

That Imperial control is very reliable as far as I have experienced. My Tstat opens at 180 and the control is adjusted to come on at 195. I have an override switch inside on the dash plus an indicator that is on when 12V is applied to the fan, (a diagnostic so that I can quickly distinguish between fan or control if the fan fails to come on when it should). It is easy to set the control up with an ON-OFF-ON switch for Force ON (panic button) - Force OFF (prevent fan from coming on, as in fording deep water) - ON Normal (controller operates the fan).

I'd like to say this design was totally my own idea, but NO. I took what I considered the best part of 3 or 4 different articles in Ford Muscle Magazine and combined them and added my twist on them. That has worked out, for me anyway, to be a super cooling system. Of course you have to start with a good cooling system (clean inside). There is still one more piece to go and that is a full time electric water pump, and eliminating the mechanical pump, a two edged sword so to speak.

So wait a minute, are you somehow suggesting that the murky orangish coolant with the floating chunks of love & devotion that I'm running is somehow a less than ideal starting point for cooling system such as you have described ?? Say it ain't so.

Admittedly I have always been a fan (haha, look, I made a funny) of hi-flow waterpumps as opposed to electrics. But I can see the merits, I guess at some point you have to just start trusting the technology and I figure elec. waterpumps have been around long enuf for the problems to have been worked out. At this point the largest variable is probably the skill of the guy choosing & installing componants. I've always been a bit gunshy after seening a friends brother burn a really nice 67' Firebird down to the rims after installing a big block. It ran & drove beautifully but he wanted that 427 and didn't have room for a belt-driven pump. He finally got the Rat to fire but only ran it for a few moments at a time since it had no water pump. He installed the electric pump one weekend and just a few hrs later had nothing but a smoldering ruin in his driveway. I guess that's more of a commentary on what happens when a dental tech decides to be a mechanic.
