7-7/8" Wide x 8-1/4" tall x 2-1/4" deep, low-profile, straight-blade fan improves gas mileage and boosts overall performance by maintaining proper airflow to your vehicle's radiator.
Features:
Specs:
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.

Today we're going to take a look at the Derale 8" Dyno-Cool Straight Blade Electric Fan. This fan will increase your fuel economy, horsepower, and torque, improves overall performance, can be mounted on either side of the radiator as either a pusher or a puller with no loss of airflow. If you do use it in a puller application, you do want to wire this to what the colors say on the label right here. The positive lead, which is the blue wire, is for your power, and the ground which is your black wire. If you do use it in a pusher application, you want to reverse the connections to change the airflow directions. This has a very ultra-low-profile design for tight applications. This does come with everything shown here: the mounting kit and a nice set of detailed instructions on how to install it. The maximum cubic feet per minute on this fan would be 350.
The power amp draw is only 5.3 amps. I do want to give you a few dimensions. The overall width, edge to edge, is going to be right at 7 7/8 inch. The overall height, from the bottom to the top, is 8 1/4 inches. The depth, from the front to the very back, is going to be right at 2 1/4 inches deep. The fan itself we mentioned is an 8-inch fan, and the depth on the fan is 1 1/4 inches deep. That should do it for the review of on the Derale Dyno-Cool Straight Blade Electric Fan..

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.

This fan is for a project that will not be completed until the middle of 2014 or later. I plan to use it to increase the air flow through the air conditioner condenser in my 1969 Corvair convertible. I will be ordering another fan since my design requires two fans for greatest efficiency and the flow rate for these fans is on the low side. The 500 cfm fans comes with too many items that are useless for my application thereby being too expensive. Dale Bartley 77284

Works great thanks mine got a hole in it and i replaced it with this one. 130315

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
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.

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
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
Review from a similar Dyno-Cool in Radiator Fans
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 is an excellent price and appears to have more cooling capacity over the OEM cooler. Installed very easily. This was used on an 08 HONDA PILOT 135385
Review from a similar Dyno-Cool in Radiator Fans
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

Easy install, works great. Installed on a 2001 Jeep Grand Cherokee. I tow a 19' boat and haven't had any transmission issues since. 293582
Review from a similar 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

I am also very happy with etrailer.coms service and selection and would definitly use them again. 14807
Review from a similar 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
Rachael H - 06/13/2018Review from a similar 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 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
Review from a similar Dyno-Cool in Radiator Fans
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

Review from a similar Dyno-Cool in Radiator Fans
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
