Derale Transmission Coolers

  • 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.

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



by:

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:

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:

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 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:

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



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



by:

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



by:

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

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:

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:

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

  • Engine Oil and Transmission Fluid Cooler Recommendation for a 2000 Chevy Tahoe
    Your idea of using a combination cooler, # D15902, is the best option for 2 reasons. First it has multiple thread types to accommodate various common engine threads and oil filters. And second, having a supplemental cooler for the transmission as well, in this case a cooler that will accept 2 fluids, will help get the most life out of the transmission (since factory coolers are adequate at best). So you are right on the money with the combination cooler and it is what I would have recommended...

If you have the space in front of your AC Condenser then you will be able to mount the cooler. You will also need to make sure that there is room for the oil filter to be spaced out 2 inches away from the bottom of where it is now located. The bottom of the filter will be 2 inches farther down or out from the engine block. Once the Oil filter adapter and the cooler are mounted...

  • How to Determine Transmission Return Line for Installing Cooler on Ford F-150
    The best way to determine which line on a transmission cooler is the return line from the radiator is to use the following procedure: 1. Start engine while engine is cold 2. Place transmission shift lever in drive for no more than 10 seconds 3. Place in Park, stop engine, and remove keys 4. Identify the oil return line by feeling both oil lines. The coolest line is the oil return line. On the aftermarket transmission cooler the ports are not input specific or output specific. It is not...

  • What Does Tow Mode Switch Do On 2004 GMC Sierra
    The tow mode switch on your shifter is designed to change the shift points of the transmission and makes the shifting a little quicker and harder and it is recommended that it be on when towing a trailer. It will downshift faster when going up a hill when towing and will use engine braking when going downhill. A transmission cooler like the Derale Combination Transmission and Engine Oil Cooler, part # D15902 serves two purposes. It is divided in to two sections. It has and inlet and...

  • Thermostat To Use with the Transmission Cooler Portion of the D15902

The difference is the diameter of the threaded portion of the barbs and not the actual barb itself that the hose attaches to.

If you have room for it check out the Derale Transmission Cooler # D13503. This cooler measures 11" wide x 8-3/4" tall x 7/8" deep and would do an excellent job.

  • Tips for Putting a Hose on the Hose Barbs on a Derale Combination Transmission and Oil Cooler
    In order to work the hose onto the inlet barbs in the Derale Combination Transmission and Engine Oil Cooler, # D15902, it helps if you use a little transmission fluid (if it is the transmission line) or oil (if it is the oil line) around the inside of the hose and on the inlet. This will lubricate it some and then it is just a matter of a little muscle to wiggle the hose on. I have included a link to a video showing a transmission cooler installation.

    Based on my research the 1998 Fleetwood Bounder M-36S Class A RV with the Ford 460 engine is based on the Ford F-53 chassis. Coolers are not vehicle-speciofic; you can install as large a cooler as you have space to mount one. Coolers are also not fluid specific; the same cooler model can be used for engine oil and for transmission fluid or even power steering fluid.
