Expert Posts: 1351 Location: Valley Forge, Pa. | Who added electric fans and how did you add the switch? Need to replace my radiator. Have a similar size aluminum but it sits away more from the motor. I would need a 4" spacer and not interested in putting the fan that far off the pump. I'm going to remove the water pump fan and add 2 12" electric fans. What type temp. switches are used? Do you use a sensor switch that mounts on the radiator and uses the radiator temp? Cut the upper hose and install a switch? Use the intake switch to the gauge with some sort of "T"? | ||

Expert Posts: 3802 Location: NorCal | I've installed electric fans on two of my FL cars. I use the Derale #16759 controller, it's adjustable and has a temp probe that inserts in the radiator fins. This controller has a limited current capacity so, if the fan(s) have a high current draw, you'll need to install a high-amp ISO relay to carry the fan load. Also available at Summit. https://www.summitracing.com/parts/der-16759?seid=srese2 | ||

Expert Posts: 1351 Location: Valley Forge, Pa. | And they did what you needed? I've been very lucky that even with my radiator at less than half the water, it has never overheated and....with very low water, it DID over heat and it showed on the gauge. I have had cars that overheated on a sunny day. Thanks for your time and your help! | ||

Regular Posts: 62 Location: Springfield, MO | Lots of people have talked about this online (not necessarily forwardlook),but HAMB would be a good source. I gather the old Ford Panther fans are pretty popular and can still be found cheap at the pick n pulls. You might wire a manual as well as an automatic temp sending switch so that you can turn it on when you know you will need it. I have seen some dudes do that as well. | ||

Expert 5K+ Posts: 9883 Location: So. Cal | They key to doing this effectively, is getting decent fans that can actually pull well - especially if you have an A/C condenser in front of it. Many aftermarket fans are crap, designed as cheap "helper" fans, so carefully check the specs on them. Also, I've never liked anything that goes through the fins on my radiator. I would recommend using a water sensor. | ||

Expert Posts: 4110 Location: Connecticut | Can someone explain why an extra fan is needed ? My Plymouth with a four blade fan does fine during the summer months. The needle is between 1/3 and 1/2. In traffic, I've seen it go up to 3/4, which is normal. | ||

Expert 5K+ Posts: 5054 | typically two electric fans are used in all setups. They pull to much power to move one giant fan... That thing pulls a ton of horsepower off the engine... I think i saw somewhere near 20 hp loss on a hemi . It also depends on your clutch... if its new it pulls a lot more... If old it wont cool. I would never want to see my temp over 50%. I know older cars can go over that but I wouldnt want to see it. | ||

Doesn't matter if I need or not. Just in case.... But usually a high-performance radiator net is enough to get the temperature problem under control and the original design is then retained. I don't like the look and the sound of the e-fans either Edited by ToMopar 2022-08-05 3:20 AM | ||

Expert Posts: 2206 Location: Muskego, WI | I have a single electric fan in my 1956 Imperial and it works well to cool the car. I'm running a 392 Hemi water pump and accessories which position the pulley and fan to low to run the mechanical fan with the factory radiator design/position. I have a full shroud with rubber flaps in the corners that open when the car is going down the road. The shroud ensures that the fan pulls air through the entire radiator surface. I have EFI, the controller allows me to simply input a turn on and shut off temp for the fan, but I also have a manual override switch just in case. It does chew up a lot of amperage when running, which is only when in traffic or idling. | ||

Veteran Posts: 255 Location: Dunnellon, FL | I used a fan with shroud from a Chevy HHR on my former ‘’60 Plymouth. I bought it new, I think from Rock Auto. Fit perfectly my BeCool aluminum radiator. I just used a manual switch, since I ran it sometimes after the engine was shut off. | ||
