  • Cooler and Install Kit
  • Derale
  • 12-1/4W x 2-1/2T x 3/4D Inch

12-1/4" Wide x 2-1/2" tall x 3/4" deep, tube-and-fin heat exchanger will keep your vehicle's power steering system functioning at its best. All-aluminum construction.


Features:

  • Cuts back on heat-related pump failures
  • Extends the life of both pump and seal
  • Constructed of durable aluminum
    • Thermal-conductive metal provides superior transfer of heat
  • Includes mounting hardware and OEM spec hose
  • Imported


Specs:

  • Inlets: 11/32" hose barb
  • Overall dimensions: 12-1/4" wide x 2-1/2" tall x 3/4" deep
  • Core length: 8-3/4"
  • Distance between inlets: 1-1/4"

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.

Review from a similar Dyno-Cool in Power Steering 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 Power Steering 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 Power Steering 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 Power Steering 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.

Review from a similar Dyno-Cool in Power Steering 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.

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

Review from a similar Dyno-Cool in Power Steering 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 Power Steering 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 Power Steering 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.

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.

Review from a similar Dyno-Cool in Power Steering 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.

I installed this cooler on a 2001 odyessey to 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 Power Steering 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 Power Steering Coolers


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.

Review from a similar Dyno-Cool in Power Steering Coolers


The trans cooler was easy to install. I had to go and buy some more hose and mounting screws to make it work but I knew that before I started. The hose was because of where I wanted it mounted. The trans cooler is keeping the transmission about 30 to 40 deg cooler then before.

Review from a similar Dyno-Cool in Power Steering Coolers


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.

I bought this cooler for my 2007 Chevy avalanche LTZ 4X4 with 5.3 motor. I also bought the adapter the adapter D13035 for my truck as well. It was a quick and easy install. I just got it installed on 2/2/2018 and took the truck for a drive and it has dropped my transmission temp at least 40 degrees. It took me around 40 min to install. Very Happy with this new addition to my truck. FYI if you buy this unit to make it easier i would order an extra Line because the one line will be cutting close to reaching location.

Review from a similar Dyno-Cool in Power Steering Coolers


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!

Review from a similar Dyno-Cool in Power Steering Coolers


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.

Review from a similar Dyno-Cool in Power Steering Coolers


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.

  • Can a Leaking Power Steering Cooler be Bypassed Until a New Cooler Can be Installed on a Ram 1500
    You will need to have a cooler that the fluid goes through in order to keep the temperature down. If you do not then the power steering pump will overheat, which is basically the worst thing for it, and lead to damage. In this case a leaking cooler is better than no cooler. If the leak is at a hose or fitting you may be able to temporarily stop the leak using an appropriate product for the leak location. You may be able to stop the leak temporarily using a power steering fluid with...

  • Power Steering Cooler Recommendation for a 2005 Dodge Ram 1500 Crew Cab
    I had a power steering fluid leak on my car and it ended up being a hose issue that was covered under a recall. This may be something you can look into by calling a dealer and asking about open recalls on your year and model Ram. If you do need to replace the cooler I would go with something larger like the Derale 4-Pass Tube-Fin Power Steering Cooler, # D13212. For the most efficiency in cooling, mount the cooler in front of the A/C condenser core in front of the radiator.
