Electric Fans

[Smitty]

What are some of the options that have been used that don't break the bank. And how did you deal with the shroud issue. All input is appreciated. Going with a serpentine belt setup from a donor '93 350 and don't think there is clearance to use the stock fan. Especially with the stock shroud. Thanks! All the information I have been getting to my questions of late have been extremely helpful.

In for info!!

I know you asked about an electric fan but, i'm running the stock serp belt setup from a 95 (same basic setup). I went with a different clutch & 18" fan to fit the OE shroud. The OE fan for my 95 donor was 19" (too large for shroud)
Truck is 4x4, the engine is set back further than a 2wd but it also has a deeper shroud. Believe this setup would work for 2wd also. will measure OAL of setup from the block if you would like (can't until Wed. - out of state)
I have run elec fans but I feel the stock shroud, engine driven fan / clutch setup performs better.

fan clutch - CQ p/n 215168 (1/8" longer than original clutch)
fan - Derale p/n 17918 18" reverse rotation (for serp belt setup)

I used a fan setup from a 2002 Toyota Camry on the '67 Panel Truck. Just a minor amount of trimming and made two small "Z" brackets to secure the top to the radiator frame. One of the bottom mounting holes lined up with a hole in the lower radiator frame and I drilled a hole in the frame on the other side to line up with the stock hole in the fan assembly. I used carriage bolts and bolted it all the way through the frame. Just go easy when you tighten them up. Pretty easy overall.... No shroud needed with this setup.

That looks really good. I'll have to keep my eyes peeled for one of those at the wreckers.

BTW, was that from a 4 or a v6?

Don't know. It was out of the car and laying in the back seat of a Jeep. Looked up the application from the numbers on it but it didn't specify 4 or 6.

I used a serpentine setup with a reverse rotation clutch fan setup. I was able to retain the factory four row radiator along with the stock shroud; I used a Derale fan blade I bought from Summit Racing, and a fan clutch from a '93 truck iirc. If you want, I can look up the part numbers for you, and get pictures. The only mod I had to make was to cut about an inch off the fan shroud, as it was a little too long. The serpentine setup is really nice, and the clutch fan is a great setup.

Dual Camaro fan setup. Works great for my LS6.0 it runs 180* all the time. 3 years and no problems at all. Fans kick on if AC is turned on and I wired a micro switch to cut them off at 25MPH they are not needed while at speed.

That really looks slick. How do you have them wired (progressive or simultaneous)? What do the "L" brackets on top attach to?

[Smitty]

Great information as usual. Will have to sort it out as things progress. The restoration shop has the rust handled and is now starting on the dents. Thanks again.

[Smitty]

Lock Doc are there any other components I need to get when I pull the fan set-up.

B.W. is the clutch and fan that you are citing stock to this serpentine setup? The one I pulled looks exactly like the unit you show in the picture.

Thanks again

I did this back in 2008 and I have never had a problem with this set up. I drive and race my truck a lot in the summer. 100 Deg day no problem. I installed it in my big block fan shroud and used a painless temp relay on at 185 deg off at 170 deg. if I did it again I would put the tab through a slot in the bottom of the shroud insted of the top.. live and learn..

Pretty neat 2 speed fan and controller setup, super cheap too.

If you want a cheap electric fan setup go with an oem fan and possibly shroud. Don't worry if the shroud doesn't fit exactly, they're just plastic. Cut it up, extend it with some fiberglass, or shorten it and epoxy it back together. With a little sanding and some paint it won't be an eyesore either.

The harder part is finding cheap oem fan relays/controllers. The Volvo one in the video above is a good candidate for 2 speed fans. Anyone know of one for using 2 single speed fans?

No, the fan is 18" the stock fan is 19" & will not clear the shroud. I needed the clutch because the new fan had a different bolt pattern

Yes, progressive through the PCM/ECM with a separate relay & fuse for each one. I have a Camaro LS1 5.7 engine in the Panel Truck. The top brackets just fasten to the top radiator frame. (see pics) I guess they would be more of a "Z" bracket than an "L" bracket. I will change that in my first post.

The relays. I didn't use the stock relays because I already had some and they wanted quite a bit more for the fan if the relays were with it.

good info here!
this might sound like a dumb question, but here goes..... when I go electric fan, what all needs to be done to delete the clutch fan so I can free up space?

thanks fellas

Un bolt it and put short bolts back in the place of the long ones.

Very clean setup. I like it a lot. I'm just getting to where I'm putting my rig back together and have been considering an electric fan setup. The price is right too.

Did you use the painless temp relay kit with the 30 amp breaker? Or just the relay itself wired to the unit.

By chance did you put an "over ride" switch in line so you could turn the fan on manually if you want to?

Is that the stock 67-72 C10 shroud?

[70short]

OK so yes that looks like the factory shroud which is 20 opening. So those mount tabs must stick out quite a ways. Anything else I should know because I'm going to do this mod. I really like it.

I really like the Jeep Electric fan setup although the prices have jumped for the fan $171.45
https://moparonlineparts.com/mop-parts/#parts

and the JEGS wiring kit has gone done $34.99
http://www.jegs.com/webapp/wcs/store...rsistYmm=false

so for around $210 and shipping it can still be done and I'm thinking about doing it this spring.
