Electric cooling fan conversion - 1979 c3
1979 c3
Engine 383 Stroker
Has anyone replaced the stock cooling fan with electrical ones. single/dual. It seems I only have 1.75 inches between the radiator and the A frame arm of the suspension. Also have you kept the shroud in the conversion, if a single fan.
If you could give me the brand, model or any suggestion i would appreciate it
Thank you

yes,
I've ditched the mechanical fan and shroud on mine. I now run a Permacool 19115 HP 16" fan. Got the idea from Olivier (GSC3).
you can find the dimensions here. http://www.perma-cool.com/Catalog/Cat_page16.html
You won't even need it to get anywhere near the control arms. It moves almost 3000 CFM.

im using thinline 220 series it covers entire rad, and had to cut 1 small peice of the built in shroud/webbing to clear driver side a-arm. it pulls 3000cfm but seems to be better now with high output alternator. i couldnt be happier

Me, too. You don't need to spend big dollars on some Eye-Talian setup.

I use a '89 V8 camaro radiator for 150 bux, and a '87 vette fan, in the original shroud, modded up to fit/mount everything, use pipe wrapping from HD to fill in the voids....works well, as long as the radiator does not go into the weeping mode of water loss/evaporation, and the fan motor has full power...any electric brush type motor can get a bad spot on the armateur, and loose power, the a/c blower just quits when that happens, as no power flows in that dead zone, but the radiator fans are turned over by airflow at speed, and so will remain running, just not pulling any serious airflow, and so coming off the freeway onto a city street will allow overheating in a few blocks/or sitting at a light....lack of airflow, but fan is running, just not fast....can be overlooked really easy...

This 16" Permicool keeps the 406 at 190 degrees,at a dead stop on 95 degree days. I found this out last summer when PENNDOT repaved the highway I commute on.
I added the aluminum radiator at the same time,so I can't say if it's all fan that did the trick.I replaced the fan because of one 6500 rpm blip on the way home,that some how managed to work the engine driven fan loose.I decided then that an electric fan was cheaper than a new hood.

I used twin fans with eloectric controls for each. Mount almost perfectly. No problem 0on the clearance.. You can see in the pic... I haven't updated my website in a long time, but there are a few therein cooling section. They work great!!!

The hottest it has been since I've mounted it was upper 80's and it was fine. The only time the motor gets hot in traffic is with the air on, but even then it was only 200, and I'd been idling a LONG time. Running the A/C seems to raise the idling temps by 20 degrees. I have an adjustable switch that comes on at about 180 ( I have a 160 T-stat). I'm still running a 4 row copper radiator and the tranny fluid is still plumbed in. I intend to get a tranny cooler and mount it away from the radiator. I might even someday get an aluminum radiator to redue weight. We'll see how it does in a few months when it gets in the 90's.
I used the through-fin mounting kit supplied with the fan, but followed Permacool's instructions: the plastic strap is resting on the bottom of a "V" on the fins rather than on the top of a tube if the "V" was upside down.
Even though it's fairly new, I beat the radiator up pretty good when I did the motor swap and then the fan swap. Those control arms are SO close during installation

i'd like to bolt at least the bottom of the fan to the rad support, so there is no weight pulling down on the fins. do u think that can be done without pulling the rad?
thanks!

Speaking of $$$....what's a reasonable price to pay for an electric fan setup??

And, BTW, the Permacool can be either a pusher or a puller, depending on how you wire it. Puller (behind the radiator) is more efficient.
