Derale Transmission Coolers

  • Tube-Fin Cooler
  • Car
  • 13W x 5D x 3/4D Inch
  • Standard Mount
  • With 11/32 Inch Hose Barb Inlets
  • Derale

13" Wide x 5" tall x 3/4" deep, reliable, all-aluminum tube-and-fin cooler extends the life and improves overall functioning of your vehicle's transmission.


Features:

  • Improves functioning and overall performance of transmission
  • Extends life of transmission and prolongs period between necessary fluid changes
  • Cuts down on heat-related failures
  • Agitates fluid with built-in, embossed turbulators for more efficient cooling
  • Constructed of durable, lightweight aluminum
    • Thermal-conductive metal provides excellent transfer of heat
  • Includes:
    • High-temperature, OEM spec hose with stainless steel clamps
    • Nylon mounting rods
    • Insta-dapt radiator adapter
  • Recommended for subcompact cars
  • Imported


Specs:

  • Inlets: 11/32" hose barb
  • Overall dimensions: 13" wide x 5" tall x 3/4" deep
  • Core width: 10-1/8"
  • Distance between inlets: 3-3/4"
  • 1-Year warranty


Note: The Derale Insta-dapt radiator adapter fits most vehicles with 5/16" transmission lines, but not all. In some cases, additional fittings or alteration of the OEM lines or hoses may be required for installation.


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.

2009 GMC Acadia
I installed this cooler on my 2012 Acadia. Although the Acadia has the tow package, the transmission tends to run hot when towing a 3000 pound trailer. The Derale 12903 appears to be a good choice for the Acadia; it's about a quarter the size of the radiator, so there's plenty of room to install it.

My only complaint about this unit is the supplied retainers, which pass through the cooler, AC condenser and radiator and are held in place by clips on the back side of the radiator. The first time I put any pressure on the cooler three of the clips failed. I replaced the supplied retainers with cable ties, which worked much better. I ran the cable ties through the cooler and condenser fins, then back through the condenser fins and the cooler's mounting brackets. I did use the pads supplied with the unit to keep the cooler spaced away from the condenser.

Since the cooling fans block access to the back side of the radiator, I took the condenser loose from the radiator, which allowed me to get to the back side of the condenser. I then attached the cooler to the condenser alone.

Installation required removal of the Acadia's front fascia and a few other parts, such as the plastic brace that supports the upper part of the fascia. I ran the cooler's hoses over the top of the condenser and radiator, which required putting a small notch in the plastic brace. I used the Derale 13035 adapter to connect to the radiator transmission cooler. By using this adapter, it's not necessary to cut the factory transmission lines. The auxiliary cooler can be quickly taken out of the system if necessary just by pulling the adapter out of the radiator, taking the hose off the factory transmission line and plugging the transmission line back into the radiator.

I haven't yet towed with the car, but the cooler seems to be working quite well. Prior to installing the cooler, both the engine coolant and transmission fluid temperatures were 90C (195F) at highway speeds (according to my scan tool). Now the transmission fluid temperature has dropped to 75-80C (165-175F) while the coolant temp is unchanged. I assume it will reduce the temperature while towing much more than that.

Hose barbs on the radiator are 0.4 inches, not 0.345. With the added raised portion it's almost 0.5 inches. It's basically impossible to force a 0.335 ID hose over a barb that big. Hopefully I was sent the wrong cooler with the kit, I could only get them on a little past the raised section. The hose will probably split too. You can see how little I was able to push them on in the photo, I bent some fins from slipping while pushing them on. Like I spent 30 minutes trying to force them on with lots of transmission fluid as lubricant.

The hose size is right for the truck. But I'm super glad I didn't order the adapter to the truck radiator if this is the quality of their radiators. Two male to male SS 3/8 inch hose barbs worked perfectly to hook the hoses to the existing line after cutting it.

The hose clamps were almost too big also. They are almost completely tightened down to where the threads stopped. The two in the photo are mine because I needed 6 and the kit only has 4.

It's almost like I was sent partially a kit for 13/32 or 3/8 inch hose. With only the hose being correct.

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!

It’s working great! Installed transmission temperature gauge also and temp is keeping between 110-130F on any driving conditions. Looks like new, no corrosion any kind, very happy with this one!

2010 Chevrolet Avalanche
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.

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.

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.

Removing the front bumper/grill on my Odyssey was a must! Installation was pretty much straight forward once you confirm the feed, and return connection points. Mounting the actual cooler to the front radiator was the easiest part of the job. My Odyssey made two 650 mile trips pulling 2050 lbs with no problems so I’m very happy with the cooler!

A year later and the cooler is still doing great! We’re presently on a trip and to date we’ve logged 3500 miles with no issues. One of the smartest decisions I’ve made for my 2012 Odyssey which is approaching 200K miles.

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.

  • Is Transmission Cooler Recommended for 2019 Nissan Pathfinder Towing Within 500 Lbs of Max Capacity
    You're getting pretty close to the towing capacity of that vehicle, so yes I would without doubt recommend a transmission cooler. A transmission cooler is some super-inexpensive insurance that will do a great job of protecting your transmission. The best place to install a cooler is right behind the grille, in front of the radiator. You'll want to choose a cooler that fits the available space, and you needn't worry about the cooler blocking the air flow to the radiator. There's enough...

  • Transmission and Power Steering Cooler Recommendations for a 2007 Honda Odyssey

It is always a good idea to use a transmission cooler and power steering cooler when towing, even if the load is a light one. Doing so will extend the life and optimum operating performance of the components. For a transmission cooler, I recommend...

  • Which Class Transmission Cooler Should be Used on a 2006 Honda Odyssey
    Derale adds Class information to try to make it easier to select the proper transmission cooler for a given vehicle. It is supposed to match the Class of the trailer hitch you have. But really, transmission fluid cannot be over-cooled so going with the largest cooler that will fit is the way to go. The most popular option for a 2006 Honda Odyssey is a Class III cooler # D13502. It is 11 inches wide, 7-1/4 inches tall, and 7/8 inches deep. I have linked a video showing an installation on...

  • Would the Derale Transmission Cooler part # D12901 be Adequate for 2007 Honda Odyssey Towing Pop Up
    Transmission coolers like the part # D12901 don't really have weight ratings. We put them in classifications based on size and the general cooling efficiency they would have. The part # D12901 would work just as good towing a 2,000 lb trailer as a 2,100 lb trailer. This will work just fine on your 2007 Honda Odyssey.

    When choosing a transmission cooler, there are several factors that go into deciding the best one for your needs.

  • Is a Transmission Cooler Required when Just Carrying Bikes on a 2015 Honda Odyssey
    No, a supplemental transmission cooler is not going to be required if you aren't towing a trailer with your 2015 Honda Odyssey. But adding a cooler certainly would not hurt since transmission fluid cannot be overcooled and it will help you to get the longest life out of your transmission. Even a small one, # D12901, will help.

  • Transmission Cooler Recommendation for a 2005 Acura MDX Towing a 3,750 Pound Boat and Trailer
    The Class of transmission cooler you use will depend more on where you can mount it. The most efficient place is in front of the AC condenser. You could then use a Class I cooler, like # D12901. If mounted behind the condenser, I would go with a Class II like # D12906. If mounted behind the radiator I would go with a Class III like # D13502. The problem is that the further away from the front of the vehicle a cooler is mounted, the less airflow it receives. The less airflow a coolers...

    I am not sure what, if any, benefit new cooler lines would offer. But the right transmission cooler will do the trick. If your 2009 Chevy Equinox has the 3.4 liter engine, we have several options. I recommend the Derale Transmission Cooler, # D12901. This has the simplest, tube fin design. It is fairly small so it should be easy to find the best mounting point. There are essentially three places to mount a transmission cooler.

  • Transmission Cooler and Suspension Enhancement for a 1995 Plymouth Voyager
    A transmission cooler would definitely be a good call for your 1995 Plymouth Voyager since the factory cooler by itself is adequate at best for non-towing situations. The best way to pick out a transmission cooler is to measure the amount of space you have in front of your radiator and pick out the largest cooler that would fit there. If you have room for it I would recommend you go with a Derale Transmision Cooler part # D13502. This cooler measures 11 inches wide by 7-1/4 inches tall...
