Need Help Installing Electric Radiator Fan - The 1947 - Present Chevrolet & GMC Truck Message Board Network

MashTheGas 72 · 01-05-2014, 09:31 PM

I'm getting ready to put an electric fan setup on my 72 GMC. Does anyone know where I can get an aluminium Frame to fit a 16" fan or 2 10". I have a Gm 4 row Radiator. I've seen some really nice setups. Can I buy this somewhere. I did find a couple on ebay but non my size radiator. Does anyone build these? Thanks again for any help!

I had a buddy of mine build me one utilizing oem fans. Follow my build link for a look.

Do you know if he would build another one for a 4 core radiator? Thanks Lyn

Ya might check with Wes at Classic Heartbeat.Com . He's a vendor on this forum, and IIRC, he sells fan shrouds for electric fans?

Your stock fan shroud and a 18" (?) electric fan from a jeep = awesome. Some say it's too loud. If you have super quiet exhaust...maybe. I run this set up with a thermostat switch. Works great.

Do you have any pics of your setup. What year Jeep fan did you use if you don't mind me asking? I've got a brand new fan shroud I bought from LMC that I haven't ever mounted up. Could you tell me which thermostat switch you went with. Thanks alot.

Any good radiator shop can make you a custom shroud if you are on a time restraint. Most have fans for just about any combination. Just make sure your electric fans are the slim design as space can be tight. In my application I just took the 4 core rad to him after measuring my available space. Good to support your local economy too many of the Mom n Pop shops no longer are around.

Nice setup Wes!

I run 2 -14" fans , on a steel shelf, with Painless controls. The mix kept my 383 cool, as well it will work with the 5.3? Longhorn

cableguy0 · 01-06-2014, 08:35 PM

I ran junkyard fans off of a 93 Maxima. I only had to trim the shroud slightly so that the fans would sit down right between the radiator tanks. I just drilled and tapped the top and bottom steel support for the radiator core and used 5/16's bolt to attach the fans using the tabs made to the fans.Fit real good worked great and was free except the two relays. They were two speed fans but I just wired them to the high speed only. With a 195 thermostat,stock 4 core brass radiator,stock water pump my alum headed 10.5-1 compression 355 stayed at 200 in traffic in July.

Does anyone know if this fan is the right one to use with stock fan shroud on my 72 GMC for electric fan conversion?

Why do you want an electric fan. Get a 7 blade fan with a shroud and you will be fine.

MashTheGas 72 · 01-29-2014, 09:56 PM

I Have one! I would just like to go with electric and free up some Hp.
