Whereas belt-driven fans use up power from the engine to turn, electric fans do not, thus removing any unnecessary load and increasing both fuel economy and horsepower. In addition, you do not have to worry about an electric fan's slowing down at low RPM, as many belt-driven fans do, so you are guaranteed sufficient airflow regardless of the vehicle speed.

While this assembly is intended for primary cooling and should, therefore, provide enough CFM to replace your vehicle's factory fan, you will still need to determine the CFM requirements for your engine before making your purchase. And remember, engines that have been modified or vehicles often used for towing may require additional CFM. There is no limit to the number of fans you can install, as long they all fit appropriately and are mounted on the same side of your radiator so that they do not cancel each other out.

Two types of turn-on sources are available for this fan. The Derale Lighted On/Off Switch for Electric Fans (D16740) allows for manual control of your fan so that you can choose when to turn it on and off. Thermostatic controls, on the other hand, send a signal to the fan, directing it to shut off when fluid temperatures reach an appropriate level, thus saving power. Once the temperature climbs again and additional cooling is needed, the fan is automatically turned back on. Thermostat switches can be single-stage with pre-set temperatures - D16735, D16738, D16739, D16720 and D16721 - or adjustable - D16778 and D16779.

Do you have a question about this Radiator Fan?


  • How to Determine if Derale 32" High-Output, Electric Radiator Fan-and-Shroud Assembly Will Work
  • Even though the engine components we carry are meant to be a supplement to the OEM components we have heard of people using them as replacements for OEM products. If you want to try using the Derale 32" High-Output, Electric Radiator Fan-and-Shroud Assembly # D16934 as a replacement then you need to make sure the 4,000 CFM (cubic feet per minute) is a high enough rating and that the overall dimensions of this product will fit your aplpication.

  • How to Pick Out an Electric Radiator Fan for a 2001 Chevy Express 1500 with 5.7 Liter Motor
  • There isn't one specific electric fan for your 2001 Chevy Express 1500 5.7 liter. You will need to compare the available space you have to mount a fan to the dimensions of the available fans. Keep in mind that if you place the fan in front of the radiator it will need to be a pusher fan. If it is mounted behind the radiator it will need to be a puller fan. Fan # D16934 is a puller so it would have to go behind the radiator. This fan measures 31-3/8" wide x 15-3/4" tall x 3-1/4" deep...

  • How Much Cubic Feet Per Minute is Needed in an Electric Fan for a 2000 Ford F-250 Super Duty
  • Typically, a small block V8 engine would need 2,200 to 3,000 CFM. A big block V8 would need 3,400 to 4,500 CFM. I recommend going with the highest CFM in a fan that will fit in the available space on your Ford F-250. The fan that you have referenced, # D16934, would be plenty of air flow. This fan is designed as a puller only, and gets mounted behind the radiator to pull air through. You would need to have a space 31-3/8 inches wide, 15-3/4 inches tall, and 3-1/4 inches deep behind the...

  • Electric Fan with Shroud Availability for Chevy Truck with 454 Big Block
  • The typical CFM requirement for a big block vehicle like your 454 truck for a fan is 3,500 to 4,500 lbs. The part # D16934 can pull 4,000 CFM so it would fall within the range required. This is the highest rated electric fan system we offer so it would be the best option we have. As long as the dimensions of it match the available room you have and the radiator this would be a great option. This fan setup measures 31-3/8" Wide x 15-3/4" tall x 3-1/4" deep. Since you have 3-1/2 inches...

  • Thermostat and Probe for a High-Output, Electric Radiator Fan-and-Shroud Assembly, # D16934
  • Because the High-Output, Electric Radiator Fan-and-Shroud Assembly, # D16934, contains two fans that operate independent of one another, you will need two Adjustable Fan-Control Thermostats with Thread-In Probes, # D16749. The wiring that comes with the thermostat is required and each fan will need a complete D16749 to make them operable. The only extra wiring that might be needed is if the mounting locations for the thermostat and/or probe are too far away. In that case, extra wiring...

  • Derale 32" High-Output, Electric Radiator Fan # D16934 Slows Idle on 2001 Chevy Express Van
  • The sudden draw of 50 amps when fan # D16934 turns on will cause that momentary decline that you are experiencing. The higher the RPMs of the motor the less it will affect anything. You can certainly go to a higher capacity alternator but it is not 100 percent necessary provided the draw of the fan is not overdrawing the electrical system.

  • Recommendation for Cooling the Coolant and Transmission Fluid Temperature on a 2008 Chevy Avalanche
  • For the radiator coolant temperature, I recommend adding a supplemental fan or fans depending on how much space you have under the hood. There is no limit to the amount of fans you can have. A pusher fan, mounted in front of the radiator pushing air through it, would be the most efficient (provided that the factory fan is mounted on the same side and pushes air through in the same direction). A puller fan would be used on the other side of the radiator to pull air through. The largest electric...

  • Is there a Direct Fit Electric Fan Kit for a 1987 Chevrolet Pickup
  • Direct fit kits are not typically available when swapping from mechanical to electric fans. The best thing to do is measure the backside of your radiator and figure out how much space you have. The kit you were looking at has an overall dimension of 31-3/8 inches wide, 15-3/4 inches tall, and 3-1/4 inches deep. Provided you have enough room for this assembly to fit, it should be able to be installed with no problem. Since you want a fan kit with that is controlled via a thermostatic...

  • Will the High-Output, Dual Electric Radiator Fan Assembly 4,000 CFM # D16934 Fit on a 1985 Ford

  • How to Determine the Best Electric Radiator Fan for a 2006 Dodge Ram 1500 with 5.7 Liter
  • The electric fans we carry are not vehicle specific. You have to determine how much space is available in the area you want to install a fan or fans. The 4000 cubic feet per minute fans we carry, see link to the right, are the highest output we have available. Depth is probably going to be the biggest concern. Electric fans # D16934 are the thinnest overall at 3-1/4 inches deep. The next step down in terms of air flow is # D16834 at 2700 cubic feet per minute. But it is also only...
