Derale Radiator Fans - D18910

  • 10 Inch Diameter
  • Electric Fans
  • 590 CFM
  • Dyno-Cool Fan
  • Derale
  • Curved Blade

11-1/2" Wide x 10-3/4" tall x 2-3/8" 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: 11-1/2" wide x 10-3/4" tall x 2-3/8" deep
  • Fan dimensions: 10" diameter x 1-1/2" deep
  • Distance between mounting holes: 8-7/8"
  • Maximum cubic feet per minute: 590
  • Power draw: 5.3 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.

I mounted this fan in the puller position on my auxiliary transmission cooler so that I can tow a 15ft travel trailer with my minivan. Installation was sweet. There was an instruction page in the box and enough parts for mounting. I was surprised at how much air this thing moves. I wouldn't call it noisy since the fan spins smoothly and quietly when I tested it out in the open, but when mounted in the congested grill area of my 2012 Dodge Grand Caravan I can definitely hear it hum more than the stock radiator fan. It pushes that much air. I would definitely recommend this product. 413989

etrailer is always nice to deal with. Good service & good pricing. I received this order in a timely manner. My concern was noise / sound level. This fan moves a lot of air and is incredibly quiet. This is going to cool a generator enclosure box in my RV (air cooled generator) and the project is to replace a noisy standard generator with a new one, so noise reduction is key and this is the right fan for me. Don't hesitate to pick this one if quiet is a priority for you too. 107896

Tested fan after reversing blade, moves air well, also have to reverse wires when installing if pusher is what you want. Not a flimsy fan. Fast shipping. 79742

Review from a similar Derale Dyno-Cool in Radiator Fans


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

Just got it in the mail the other day. Fast shipping, never have had an issue. Having it installed right now. Feels like it is well constructed and should do the job. We shall see what happens. 18179

What is the rated towing weight for a 1999 Honda CR-V? Does a trannie cooler install fairly easily on the Honda CR-Vs? What is the most effective mounting location for the finned cooler? How does the addition of a trannie cooler effect the volume of fluid and fluid level reading on the dip stick? Thanks for your time and expertise.

The towing capacity question is a loaded one. For that, I would refer back to the owners manual. It can vary depending on engine, transmission, drive configuration and more. Furthermore, Honda has some very specific guidelines regarding towing so it's best to defer to them. Installing a trans cooler on a full size truck can be easier because of the extra space, but it is not particularly difficult on any vehicle. We actually have a video of a cooler being installed on a 2006 C-V. We remove the front bumper cover for the video, but you may find you do not need to. (See link). The most effective location will be in front of both the radiator and the A/C condenser. As you move behind each cooling device, the efficiency diminishes. We put ours in front of everything on the 2006 in the video. For fluid capacity, plan on an extra 1/2 quart. Depending on cooler size and construction, it will vary some, but 1/2 qt. is a good rule of thumb.

Review from a similar Derale 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

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

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

This is a customer service review not a product review. Leeza J. was very helpful in helping me get everything needed for adding a secondary transmission cooler to my Chevy truck. I ordered 3 different items and the one item was not in stock and I was promised that I would be notified when it arrived. I was notified that the item was in stock 2 days later and I received the package a few days after that. Very good service that impressed me. 377288

Review from a similar Derale Dyno-Cool in Radiator Fans


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

Review from a similar Derale Dyno-Cool in Radiator Fans


Very easy install, absolutely no leaks anywhere in the system after putting it into service. I did have to get additional hose for the install due to the location I chose for the cooler (personal preference). I centered it on the bumper side of the radiator to provide the best air flow. Remember to get a quart of transmission fluid to accomodate the larger system volume after the install. I took my grill off to provide the most room for putting the cooler in rather than trying to wedge it between the radiator and grill, made install the nylon fasteners through the radiator and cooler much easier. Should last for many years. 61081

Review from a similar Derale Dyno-Cool in Radiator Fans


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

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

Hi I need to know at what temp. is exactly activated Thanks

This fan does not include a thermostat system. It can be wired into the original electrical system and will then operate according to the thermostat system in the vehicle. It can also be wired to an on/off switch but that is usually only done if off-road and race applications. We have plenty of thermostat options, sold separately, for determining the temperature at which the fan kicks on. For example, part D16735 kicks on at 180 degrees and shuts off at 165 degrees. Part D16759 is an adjustable thermostat system. Turn-on temperate can be set any where between 150 and 240 degrees. The turn-off temperature will always be 10 degrees less than the turn-on temperature.

Review from a similar Derale Dyno-Cool in Radiator Fans


good product form a great company ! my only complaint is this was listed as for my specific truck, but the "insta-dapt" supplied doesn't fit the Dodge truck of my year. even doing my research ahead of time, it seems to be hit or miss whether it would fit as some of them come with 5/16 fittings and some (like mine) come with 9/16 fittings. it doesnt matter the engine size, even other 3.7L dodge trucks of the same year have 5/16 fittings... I think Dodge made a change middle year, but never let the consumer know as mine is a late year '04. no dig deal as I was able to assemble it anyways and got it up and running great and both the radiator and trans are running much cooler now ! I attached the D12902 to the bumper as you will see in attached images. 2 attached images are just before finishing, bumper hasnt been attached yet, one of them is after everything was complete. 189096

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

  • 1956 Chevy Electric Radiator Fan Recommendations
    In order to determine the correct fit fan for the front of the radiator on your 1956 Chevy you will need to measure the area in front of your radiator and determine how much room you have to work with.

  • Transmission Cooler and Fan Recommendation for a 2010 Nissan Titan SE Towing Travel Trailer
    A supplemental transmission cooler would absolutely help keep your transmission fluid temperatures down on your 2010 Nissan Titan. Since the heat issue you described is when you are backing your trailer up your best option would be a cooler with a fan since there would be limited air flow while in reverse at slow speeds. Another great thing about the coolers with fans is that you can basically mount them wherever you want since the fan provides all the airflow needed. For that I would...
