12-3/4" Wide x 7-5/8" tall x 3-1/4" deep, cooler assembly keeps your vehicle functioning at its best no matter where it is mounted. Electric fan supplies airflow to the tube-fin core. For transmissions, power steering or fuel systems.


Features:

  • Improves longevity and overall functioning of transmission, power steering or fuel system
  • Cuts down on heat-related failures
  • Offers continuous airflow via the electric fan
  • Cools efficiently with tube-fin core
    • Copper and aluminum construction ensures adequate heat transfer


Specs:

  • Inlets: -6 AN
  • Overall dimensions: 13-5/8" wide x 7-5/8" tall x 3-5/8" deep
  • Mounting dimensions: 10-7/8" wide x 5" tall
  • Distance between inlets: 6-1/4"
  • 1-Year warranty


Perhaps the simplest type of heat exchanger, the tube-fin effectively cools a variety of automotive systems. The concept is simple: Fluid cools as it travels through the core by transferring heat out to the fins. The fins then provide the surface area necessary for sufficient heat exchange to take place, allowing the heat pulled from the fluid to dissipate into the surrounding air. Quick, easy and effective.

Take it a step further with a fan-mounted unit and you can be sure that there will always be optimum airflow for your tube-fin cooler no matter where it is mounted or what sort of environment you are traveling through, making it perfect for those hot days spent sitting in traffic.

Review from a similar Dyno-Cool in Transmission Coolers


I have always loved etrailer and their service. Once again order another of these coolers. Drop my temp from 240 to 170-190 also remember to order extra hose, the adapter if needed for your vehicle make, mount kits. Love it. Perfect this one is on a 07 GMC Yukon XL always add an extra cooler on your 1500 gmc or chevys they help out so much for them.

Review from a similar Dyno-Cool in Transmission Coolers


Great cooler upgrade for my 1997 GMC Yukon! Little delivery damage, but was so easy to bend those fins back to original shape so no worries!
Nice that you had proper dimension measurements online, so it was easy to figure out what kind I can fit in my truck. Complete kit had everything I needed to get it done!
Modified old cooler bracket little bit and that was it. Works great!

Review from a similar Dyno-Cool in Transmission Coolers


Not sure of the btu output of this but it worked perfectly fine in my jeep with the factory transmission. Upgraded to a built transmission and as it seems ill need a lot more cooling capacity. No rust or corrosion so far. The clamps it ships with are a gigantic transmission hazzard... had a clamp split right down the middle on me in my drive way thankfully. I would buy different clamps if you didn't want fluid puking out of a hose at 90+ psi and kill your trans.

Review from a similar Dyno-Cool in Transmission Coolers


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.

Great product. Easy to install. Drove cross country and the transmission kept its cool. Even through the mountains in warm weather. No signs of leakage or corrosion after a year.

I installed this fan yesterday. Very powerful and works great. Currently works off a selectable switch as I need it but will switch out with the thermonswitch I got soon.

We use these fans in a training mechanism that is used in colleges and vocational schools,they hold up very well under repeated usage.

This fan looks like it will do a great job.
No
more overheated transmission.
Pulling a trailer in stop and go traffic on a 100 degree day - No problem :-)

Review from a similar Dyno-Cool in Transmission Coolers


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.

Review from a similar Dyno-Cool in Transmission Coolers


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.


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.

Works well. Just make sure it is matched to the load being towed.

Review from a similar Dyno-Cool in Transmission Coolers


Can't say anything bad about the unit. It was installed in a Jeep Grand Cherokee that I use to haul trailers occasionally that weigh up to 6000 lbs. So far, I've never overheated the transmission at all, which I attribute to the addition of this cooler. Once again, thanks for a great product.

Review from a similar Dyno-Cool in Transmission Coolers


I used this cooler on a 2004 Chevy Silverado. The accessories were not needed because I needed longer hoses and fabricated my own mounting. I think the hose clamps and the hoses could be better quality. The cooler does work very well.

Review from a similar Dyno-Cool in Transmission Coolers


for my 06 colorado with the 2.8l i4. also used the derale trans oil thermostat to help with warmup of trans fluid in winter. trans never gets above 190F now and the engine will overheat (212F) before the trans does. perfect upgrade for a light duty truck/van/car to provide a little bit of cooling at a compact size. very satisfied with the product

Wanted to give my Honda better ability to handle a tow. this baby does the job. Transmission definitely cooler operation since the install. The install was simple and straight forward.


Comments
so far so great. Tho sometimes I have to remind the transmission service guys to add a bit more fluid then they are use to.

Review from a similar Dyno-Cool in Transmission Coolers


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.

Review from a similar Dyno-Cool in Transmission Coolers


i put this unit in my 2008 NIssan Titan pickup. we are going to take a 9000 mile trip this summer pulling a 27 ft HI Lo camper. The instructions were very generic. specific unit instructions would be very helpful. the grill was difficult to get out until i found a Youtube video for that. the hose provided was to short, so I made a run to the parts store. the unit appears to be well made.


Comments
we used the cooler in my 08 Titan. we pulled a 27 ft travel trailer thru 28 states and never had any issues

Review from a similar Dyno-Cool in Transmission Coolers


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.

Review from a similar Dyno-Cool in Transmission Coolers


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.

I installed this cooler on a 2001 odyesseyto help prevent a future trans failure.It was delivered quickly when promised,came with everything I needed for installation and had no problems.Overall a good product I would recommend this to anyone.
I am also very happy with etrailer.coms service and selection and would definitly use them again.

Review from a similar Dyno-Cool in Transmission Coolers


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.


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

Review from a similar Dyno-Cool in Transmission Coolers


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!

Review from a similar Dyno-Cool in Transmission Coolers


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.
