  • Electric Fans
  • 16 Inch Diameter
  • 1980 CFM
  • Dyno-Cool Fan
  • Derale
  • Curved Blade

16-1/2" Wide x 15-5/8" tall x 3-5/8" deep, efficient, curved blade electric fan will boost your vehicle's fuel economy and increase both torque and horsepower.


Features:

  • Increases fuel economy, horsepower and torque
  • Improves overall performance
  • Designed for ultimate efficiency with curved blades that can move more air
  • Can be mounted on either side of the radiator, as a pusher or puller, with no loss of airflow
  • Includes mounting kit


Specs:

  • Overall dimensions: 16-1/2" wide x 15-5/8" tall x 3-5/8" deep
  • Fan dimensions: 16" diameter x 1-1/8" deep
  • Distance between mounting holes: 14"
  • Maximum cubic feet per minute: 1,980
  • Power draw: 17.3 amps
  • 1-Year warranty


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.

Before purchasing an electric fan, be sure to determine the CFM (cubic feet per minute) requirements for your engine. 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.

Super easy install. With the installation video on Youtube it took out any of the guess work. The hose could stand to be about 3" - 5" longer if you are going to center in the A frame of an older chevy grill (I have an 06 Avalanche. I had to offset to the passenger side to use the supplied hoses) But, you can get a longer hose easy enough. Just ran over the pass and back and no leaks. Looks good so far! 377410

This product is great and installation was not bad at all. Only issue I had was that the GM radiator adaptor should come with this unit when you purchase it for a GM truck. Not as an add-on. Thought I could get it at GM but no go. I Had to work with hoses over 30 min to get them over the fittings even with trans. fluid on the hose and male fitting. So far it looks like trans temp has dropped 30 dg. 134485

Review from a similar Dyno-Cool in Radiator Fans


Ive got a 1999 4runner that had the unfortunate luck of having the integrated transmission cooler line rupture inside my radiator. needless to say, the transmission didnt agree very well with having engine coolant running through it and finally died out on me. I bought this transmission cooler to isolate the transmission and the engine cooling systems. The cooler arrived a day ahead of schedule, which is always a bonus. I didnt rate it at 5 stars because I havent had a chance to install it yet and see how it performs, but judging by the reviews that I have read so far, the customer service provided and the prompt delivery, I would say that this transmission cooler will keep my truck running for a good long while. Everything pictured arrived in the box and I have no doubt that it will perform as expected. I will definitely recommend this product and this company to my friends! 30988

I ordered this cooler for my daughter's 2012 Nissan Rogue to fix CVT transmission heating up causing it to into limp mode. When I got ready to install, I found there was no place to connect the hoses to the transmission. The vehicle only had the direct "bee hive" cooler. Install was delayed while waiting to get a "4 tube bee hive" from a different supplier for an additional $114. 551625

The part itself was easy to install and it does what it is designed to do. Only trouble with installation was with the vehicle, I had to remove part of the front cover on my 09' Avalanche to get to it. Also, I wish I had bought a black one to blend in with the rest of the radiator. 705491

It appears that my transmission temp dropped about 40-60° adding this cooler. The hose was pretty hard to attach to the cooler, even with lubrication. The hose was also to small for my vehicle so I had to source other parts to make it work. I installed it on a 2017 explorer. 661750

Review from a similar Dyno-Cool in Radiator Fans


Installed this in a 2017 Honda Ridgeline. Mounted it above the factory cooler that was already in the truck. (Flat fin side towards the a/c condenser). I used the insta-mount zip tie kit and also the flex metal mounts to anchor the cooler to the top of the factory cooler bracket as close to the a/c condenser as possible. The vertical bracket (part of the truck) that runs right down the middle of the a/c condenser has to be cut. All fairly minor fabrication. Hack saw and hand drill stuff. The fan has to be reversed to become a pusher. Followed the hood release cable from the interior to run 12 volts to power the fan on at ignition. Haven’t hooked the trailer up yet so I don’t know if this will resolve the hot tranny situation. ( I could smell the tranny getting hot before especially when we stopped at lights). Change your fluid too. etrailer delivered quickly and the cooler was well boxed and untouched. 656607


Comments
We towed our travel trailer 7500 miles last fall almost coast to coast and back. The trailer weighs 4400 lbs loaded. The Ridgeline’s towing capacity is 5k lbs. I kept our speed at around 65 mph. The truck was capable even in mountain terrain. The transmission never overheated. I did change the fluid once during the trip and again when we got back. The cooler worked. Never once did I get that burning smell. I’m almost certain that the cooler saved us a huge overhaul repair. Thanks etrailer.

Review from a similar Dyno-Cool in Radiator Fans


I just installed this on my chevy avalanche. Flipped the bottom brace around in order to mount to. The hardest part is getting the hoses on the cooler and over the return line. I ended up getting a 90 deg quick connection coming from the radiator instead of using the one I got from etrailer. This keeps the hose from bending as much. Also purchase the installation kit with a hose as you will need an extra hose. After install I wish I would have went with the next bigger unit which is 10 high instead of 7 1/2 as I had plenty of room. 591245

I purchased this for my C6 Corvette A6 transmission. I did, however, bypass the radiator and only use the transmission cooler for the C6. I purchased and used the Derale Radiator Adapter fitting 259-13035 for both the top and bottom and just capped them off to keep debris out of the reservoir. I also had to make some custom mounting brackets. This is an excellent product and it keeps the tranny in a great temperature range. 552474

After one of use on a 2005 Honda Pilot, everything is holding up just fine. The one star less is because of the difficulty in installing it on this particular vehicle. Although this is a universal component, it is MUCH easier to install on pickup trucks. Best of luck with a brand new rubber hose going on with any sort of ease. 521316


Comments
Our installers typically use some transmission fluid to make installing the rubber hose on the Insta-dapt fitting easier.

  • Will Electric Fans be Effective for 2002 Dodge Ram
    An electric fan will absolutely be able to keep up and is going to be a really good benefit for when you are towing with your 2002 Dodge Ram 2500.

    Aftermarket products such as the Derale Dyno-Cool Radiator Fan, part # D18916, and their oil and transmission coolers also, are not vehicle-specific. Any given product can be installed in any vehicle where there is ample space for mounting it. To determine if this fan will fit your 2003 Silverado you can measure the space in front of (or behind your radiator since this fan can pull or push air) to see if there is enough space to mount it.

  • Important Temperatures to Monitor When Towing and How to Lower the Temperatures If Needed
    The key temperatures to monitor when towing are the transmission fluid, engine oil and coolant temperatures. Each of these fluids will have different ranges that you will want to stay within. For transmission fluid, the ideal operating temperature is between 160 and 200 degrees. If you find that you are running over 200 degrees, I would recommend installing a supplemental transmission cooler, like part # D13504, if you do not already have one. I also recommend using the Ford radiator...
