Derale Transmission Coolers - D15902

  • Transmission and Engine Cooler
  • With 11/32 Inch Hose Barb Inlets
  • 17W x 12-1/2T x 3/4D Inch
  • Derale
  • Standard Mount

17" Wide x 12-1/2" tall x 3/4" deep, tube-fin cooler improves your vehicle's overall performance by ensuring proper fluid temperatures for both its engine and transmission with one compact system.


Features:

  • Keeps both engine and transmission cool with just 1 system
    • Engine oil and transmission fluid flow through separate tubes inside the same core for effective, simultaneous cooling
  • Improves functioning and overall performance of transmission and engine
  • Extends life of both transmission and engine and prolongs period between necessary fluid changes
  • Cuts down on heat-related failures
  • Designed with copper tubing expanded into aluminum fins for maximum heat transfer
    • Copper is the best material for conducting the heat out of the fluid while aluminum is ideal for transferring and dissipating that heat
  • Protected from possible damage during installation by plastic fin guards and powder coat finish
  • Includes:
    • Universal thermostatic sandwich adapter to provide external oil lines
    • Multiple sleeve nuts to ensure proper thread size
    • High-temperature, OEM spec hose with stainless steel clamps
    • Nylon mounting rods with pads
    • Bendable, metal mounting brackets
    • Insta-dapt radiator adapter
    • All necessary hardware
  • Made in USA


Specs:

  • Dimensions: 17" wide x 12-1/2" tall x 3/4" deep
  • Inlets: 11/32" hose barb
  • Engine filter thread size: 3/4"-16, 13/16"-16, 18 mm x 1.5 mm, 20 mm x 1.5 mm and 22 mm x 1.5 mm
  • Hose lengths:
    • 1/2" Diameter x 10'
    • 11/32" Diameter x 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. Add to that the unique turbulator technology - whereby fluids are agitated continuously to not only facilitate heat transfer, but also to prevent any undesirable drop in pressure - and you have an easy and effective cooling system.

The customer service is excellent thanks for the product. It is exactly as on the web site. Installing it on my truck. Honest, honorable people. I will continue to do business with. Thanks again



by:

The kit is excellent, with a great price. I haven’t installed it yet. The kit doesn’t include the reducer for the smaller hose. Fast shipping and great support. Detailed Instructions would be extrodinarilly helpful.



by:

Tranny side had no problems. Oil side kept leaking and was eventually disconnected. Hose clamps for hoses need to be replaced with sealed units.



by:

Fast shipping



by:

Package was delivered on time. Installed it the next day. Didn't realise it's for oil and transmition. Just needed the oil cooler. Either way it's installed. Took a bit as I mounted in a different location than in front of radiator. Only did the oil. Already have a trany cooler. However I might loop into the other side for a trany and use the whole radiator. So far so good

1 year later and still going strong. It does make a difference but have t measured the temp. However, pulling a 32 foot travel trailer I do notice a difference when I turn the fan on

Very helpful,

Without a video for my 2014 explorer and with limited written instructions I chose to find a repair shop that would do the installation. It cost me $360 to have the dual cooler installed. Most places won't consider third party parts to install and others that wanted to charge from $600 - $800 to install. Removing the front cowling, bumper, & headlights proved to be too big of a challenge without adequate instructions. Also following the installation I drove cross country pulling a trailer and I didn't trust my self with the work, and at near 70 years I no longer want to tackle such a job. Other than above I made it to California with out incident.
PS, it would have been helpful for an estimate of the additional engine oil and transmission fluid it would take to fill the new system.



by:

This is a good product and installation was fairly straight forward. The directions do not address the transmission connection to the cooler. If it did, someone would have realized a part was missing from the kit. If you are installing this cooler on a Dodge you will need a different connector than the one provided. Dodge uses a snap in, rather than screw in, connector for the transmission line. I only discovered this by watching a video online which actually gives the Derale part number for the connector (I don't remember what it is). I explained this to the customer service agent and he did not believe me nor would he send me one for free. Since I ordered this kit specifically for a Ram I feel this adaptor should have been included in the kit. Disappointed about that, otherwise it seems like a good kit. I haven't tested it yet since I am waiting for the adaptor.



by:

I installed the etrailer derale transmission cooler on my 2012 Toyota Tacoma. Hauled home a 3500lb tractor 3000 miles up hilly terrain and had no problems at all. Works great.



by:

I have not had a chance to install this unit yet. From the looks of it though it is worth it. Install should be a breeze too. I purchased this for a 05 Dodge Caravan. It cam with all the different oil filter adapters color coded for the filter you use.

How was the install? Are you happy with it? Any things you wished you knew before you began the install?- thanks. - getting ready to do the same



by:

I haven't had the transmission cooler installed yet but the service I received in ordering and the shipping was way above what I ever expected. Very friendly customer reps and they know their job.



by:

Easily installed to an 05 town and country. I think the 3/8 compression/ barbed fittings should be included in the kit though. Also do yourself a favor and make sure you get the hoses on the cooler before you tie it in place cause they go on HARD. Otherwise pretty simple. Installing for towing purposes. Took about 1 hour complete.



by:

This cooler does a good job keeping transmission oil engine oil cooler.



by:

Everything arrived intact, no damage. Instructions were clear. Products were put on with ease. Thanks



by:

This kit was easy to install on my application and works very well.



by:

Received it packaging was great the cooler was in perfect condition all items seem accounted for. Cant wait to install it.

  • Recommended Transmission Fluid and Engine Oil Cooler for a 2013 Chevrolet Express Van 3500
    I have exactly what you will need to keep both the engine oil and transmission fluid cool in your 2013 Chevrolet Express Van 3500 but a remote cooler will not be necessary. Instead, I recommend using the Derale Combination Transmission and Engine Oil Cooler part # D15902. As long as you have at least 17" wide x 12-1/2" tall x 3/4" deep of space to mount the cooler behind your grille and in front of your radiator/condenser then it will work well for you. You can expect a drop in engine oil...

  • Would Derale Transmission Fluid/Oil Cooler Fit 2017 Ford Explorer
    Hey Benjamin, yes the Derale combination oil and transmission cooler part # D15902 that you referenced does fit your 2017 Ford Explorer 3.5 liter and would do a great job keeping the engine oil and transmission fluid cooler. Are you towing with the Explorer?

  • Comparing CFM Output of Stock Electric Fan in 2011 Ford Escape V6 and Flex-a-lite Electric Fans
    I did a little research and it looks like the stock fan in a 2011 Ford Escape is 500 to 650 cubic feet per minute. Flex-a-lite fan # FLX412 puts out 2,500 cubic feet per minute but draws much more power, 22 amps. The electric fans we sell are universal items so you have to go by the dimensions of the item and compare that to the available space in the vehicle's engine compartment. Keep in mind this is a puller fan meaning that it goes between the radiator and motor and pulls air through...

  • Will Derale Combination Transmission and Engine Oil Cooler Work With 2006 Toyota Tacoma V6
    Using a combination transmission/oil cooler on your Tacoma with the V6 engine will work great. For maximum cooling ability, mount the cooler between the Tacoma's grille and the AC condenser core. I have included a photo that shows the best location for the cooler, and also attached a link to a couple of helpful articles. A combo cooler like part # D15902 includes several fittings with multiple thread sizes to ensure you get the right fittings for your truck. This cooler will cool the transmission...

  • Engine Oil & Transmission Cooler Recommendation for 2011 Dodge Durango
    The two coolers could easily fit together. Main reason is that the oil cooler kit part # D15450 that you referenced can be remote mounted basically anywhere since it comes with it's own fan. The transmission cooler part # D13504 would then need to mount in front of the radiator and fit easily.

    Yes, I will be happy to help add tow options to your 2007 Honda Odyssey. First you will need Draw-Tite Max-Frame Trailer Hitch Receiver # 75270. This hitch has a maximum tongue weight rating up to 675 lbs and gross trailer weight rating up to 4,500 lbs. If the towing capacity in your Odyssey owner's manual is lower that the capacity of this hitch, tow according to the weight limits in your manual. There is no drilling required for installation.

    I have exactly what you will need to lower both the engine oil and transmission fluid temperatures in your 2013 Ford F-150 while towing your 5th wheel trailer. For this, I recommend using the Derale Combination Transmission and Engine Oil Cooler part # D15902. As the title states this is a two in one cooler that will drop the temperature of both your vehicle's engine oil and transmission fluid around 20 to 30 degrees fahrenheit. This cooler measures 17" wide x 12-1/2" tall x 3/4" deep...

  • Recommendation For Transmission/Engine Oil Cooler on 1995 Ford Ranger V6 Towing 2750 lb Trailer
    An engine cooler and a transmission cooler are always good items to have on your vehicle when towing a trailer. Even though you mention the outside temperatures will be cold, the strain that towing a trailer will put on the engine and transmission of your vehicle will still increase the temperatures of the oil and fluid in your vehicle. The coolers will help keep those temperatures at their best operating levels for optimum life and performance of the engine and the transmission I recommend...

The oil cooler portion of this comes with several thread sizes for you to compare to your oil filter to pick out the correct one.

  • Transmission Cooler Recommendation For 2008 GMC Sierra w/ 6.0L Engine For Towing
    We can get your 2008 GMC Sierra 2500HD set up with a new auxiliary transmission cooler to get the lowest temperature possible when towing, and you're right that a smaller cooler won't provide the best temperature control. Because you cannot over-cool fluids, the rule of thumb with transmission coolers is that size matters so I recommend a large cooler from Derale, and you'll also need fittings: - Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13504 - Derale Snap-In Radiator Adapter...

  • Recommended Transmission Fluid and Engine Oil Cooler Combo for a 2006 Ford F-150 5.4L V8 Engine
    I have the perfect engine oil and transmission fluid cooler combo for the 5.4L V8 engine in your 2006 Ford F-150. The Derale Combination Transmission and Engine Oil Cooler with Multiple Threads part # D15902 uses one unit to cool both engine oil and transmission fluid. The combo cooler eliminates the need for a separate engine oil and transmission fluid cooler to be installed which ultimately blocks large amounts of airflow to your truck's radiator. As long as you have 17" wide x 12-1/2"...

    For your quad cab 2004 Dodge Dakota with 4 wheel drive and 4.7 liter V8 the towing capacity would be 6,100 lbs. The GCWR for your truck would be right at 10,500 lbs. This rating is the total weight of the truck and trailer combined.

  • Parts Needed to Install a Trailer Brake Controller on a 1999 Ford E-350 Econoline Van
    In order to install a brake controller on your 1999 Ford E-350, the first thing you are going to need is a 4-Way trailer connector # 118344. I have included a link to the isntallation instructions for you to view. Next you will need a 4 and 7-Way installation kit # ETBC7. This will provide the 7-Way, while retaining the use of the 4-Way, and all of the wiring needed to install the brake controller. I have included some links that will explain the ETBC7 installation for you. And finally...

  • Wiring to Install an Electric Brake Controller in a 2014 Chevrolet Tahoe
    The wires to install an electric brake controller into your 2014 Chevrolet Tahoe are already under the dash but unfortunately there is no plug-in adapter. You'll need to hardwire the Prodigy P3 # 90195 once you find the wiring. I've linked an article that shows the wiring you'll need to find. Transmission and oil coolers are never a bad idea when towing. Both can prolong the life of your Tahoe. Since you're considering both I suggest getting a combination cooler like the Derale # D15902....

  • Recommended Transmission Cooler for 2013 Ford Explorer
    Transmission coolers are universal items. What you will need to do is find out how much room you have to work with in front of your radiator and find a transmission cooler that will fit your application. Choosing a large cooler like part # D13502, would be a good choice for your 2013 Ford Explorer, because you cannot over-cool a transmission. Part # D13502 has significantly more cooling ability than your factory set up. If you are towing a load, up to 5,000 pounds, this transmission cooler...

  • Engine Oil and Transmission Fluid Cooler for a 2017 Ford Explorer
    Don't shoot the messenger but you cannot install components included with the factory tow package on a vehicle without the factory tow package to then obtain the tow package weight capacity. I know it might seem like you can but the manufacturer does not agree with this rationale unfortunately. The towing capacity of your 2017 Ford Explorer will remain unchanged through the life of the vehicle in the eyes of the manufacturer no what components are added. With that being said, if you are...

  • Best Transmission Cooler for Off-Roading in a 2007 Toyota FJ Cruiser in Year-Round Warm Climate
    The Class rating applied to transmission coolers is to help simplify choosing a cooler for a vehicle. Basically you would think about it in terms of a hitch class rating. So for example if your 2007 Toyota FJ Cruiser has a Class III hitch then a transmission cooler shown as a Class III is a good match. But ultimately you can use any cooler that fits in the intended mounting location. Derale transmission cooler # D13503 is a very popular option. It is a Class III but if you want something...

Next, if you don't already have a tail light wiring harness with a 4-pin connector like part # 118449, then you will want to install this item as well....

  • Recommended Transmission Cooler for 2019 Chevy Colorado Z71
    A stacked-plate cooler has the same design as a plate-fin, but it uses high-flow turbulators which makes it more efficient. Stacked-plate is typically for heavy-duty towing, and I don't think you need a combination cooler either. In your case, I believe a plate-fin will be more than enough to keep your temperature safe. You will want the largest cooler that fits in front of your radiator, which is the 11" wide x 8-3/4" tall x 7/8" deep Derale Series 8000 Plate-Fin Transmission Cooler Kit...

This transmission cooler is rated for up to 6,000 lbs and the ideal installation location is in front of the AC condenser or radiator. The installation process could take some time for someone who does not have experience installing aftermarket coolers in vehicles. For those who are mechanically inclined,...

  • How to Determine Which Transmission Line is the Return Line for Installing a Transmission Cooler
    The method we use to determine the correct line to install a transmission cooler on is pretty simple. You want to install the cooler on the return line. To determine which line is the return line you will want to start with your truck totally cooled off. Start the truck and put it in drive, apply the brakes firmly and then apply the accelerator slightly so that the rpms climb. Put the truck back in park and shut it off. Now go out and feel the two lines leaving the radiator. The cooler...
