Derale Transmission Coolers

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

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. 474576

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. 242834

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. 241406

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. 225604

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. 211318

  • Recommended Parts to Help Towing Experience with 2013 Chevy Suburban
    Adding a transmission cooler will go a long way towards extending the life of your Chevrolet Suburban's transmission, especially if you tow often or if the weight of your trailer is up near the vehicle's limits. An engine oil cooler is also a great idea to reduce oil temperatures while the vehicle is towing and under stress. This will help to prolong the life of the engine as well as improve its overall performance. For your 2013 Chevrolet Suburban I recommend taking a look at the Derale...

  • Can Engine Oil Cooler be Installed in 2018 Ford Explorer
    To answer your first question the towing capacity is set by the lowest-rated component, which is the 2,000 lb trailer weight as stated by your owner's manual. For example, even if you added the Draw-Tite Trailer Hitch # 76034, which has a 4,500 lb towing capacity and fits your '18 Explorer, you would still need to abide by the 2,000 lb capacity your owner's manual states. There is not an aftermarket part you can add which increases your capacity so if you wanted to tow a trailer that...

  • Recommended Engine Oil and Transmission Cooler for a 2010 GMC Yukon Denali AWD
    The Derale Combination Transmission and Engine Oil Cooler part # D15902 would be the best option for your 2010 GMC Yukon Denali AWD because the Derale Combination Transmission and Engine Oil Cooler for GM Applications part # D15903 does not come with the correct oil filter thread adapter you need which is a 22 mm x 1.5 mm.

  • Transmission Cooler Recommendation for 2017 Toyota RAV4
    I wish I could say yes, but your Rav4 uses a cartridge style oil filter that the # D15902 won't work with. I wish we had a similar setup that works with your style of oil filter but we do not. For just a transmission cooler though we have the Derale part # D13503 that would work well. Typically engine oil filters aren't needed or recommended for newer vehicles anyway. In most cases the cooling system for the engine is more than adequate and the oil coolers only end up lowering oil pressure...

  • Combination Engine/Transmission Oil Cooler # D15902 Recommendation for a 2003 Dodge Ram 1500
    For your 2003 Dodge Ram 1500 Quad Cab truck with a 5.7 liter Hemi you could use the Transmission/Engine Oil Cooler # D15902 that you referenced. This should greatly reduce the transmission fluid and engine oil temperatures to prolong the life of the transmission and engine in your vehicle. I attached FAQ articles on transmission coolers and engine oil coolers for you to check out.

  • Transmission Cooler Recommendations for a 2003 Toyota 4Runner
    First, the maintenance schedule for your 2003 Toyota 4Runner can be found in the owners manual. It will vary from vehicle to vehicle but unless the fluids have been changed frequently then they are probably about due. Vehicles have a factory transmission cooler normally built into the radiator. Adding a supplemental cooler is a good idea because the fluid cannot be over cooled and keeping the temperature lower will extend the transmission life. The most popular transmission cooler...

  • How Does the Transmission Cooler Portion of D15902 Route to Vehicle
    In the install video for the Combination cooler part # D15902 that you referenced it is used as a transmission and power steering fluid cooler so it does not show it getting attached to the oil filter system. The return line of the factory transmission cooler (radiator port) gets run to the inlet of the Derale cooler and then the outlet of the Derale gets run to the return line of the factory system that runs back to the transmission.

  • Does the Installation of Derale 15902 on 2015 Toyota 4Runner Require the Use of the Sandwich Adapter
    When installing the Derale # D15902, the Universal thermostatic sandwich adapter is used to add your oil lines to the cooler. It's not necessary to install the adapter during installation if you don't want to have your oil cooled as well. Using this cooler without the adapter will only bring the temperature of your coolant down and not the engine oil with this type of installation. You could look to see if there is an oil filter available that would allow you to use this feature or you...

  • Installation of Derale Combination Trans/Oil Cooler # D15902 on 2009 Honda Odyssey EX
    Fluid coolers like the Derale Combination Trans/Oil Cooler # D15902 are not vehicle-specific so you can install as large a cooler as you have space available for it. This particular dual-core cooler measures 17-inches wide x 12-1/2-inches tall x 3/4-inch deep. You can check within your engine compartment to verify that there is enough space for the cooler itself and for the connected hoses; it is important that the oil lines not have to make sharp turns that could interfere with the flow...

I have included a photo that shows the best location for the cooler, and also attached a link to a couple of helpful articles.

  • 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...

  • Engine Oil Cooler for a 2007 Chevy Silverado New Body Style with 6.0 Liter Motor
    Since the Derale Combination Transmission and Engine Oil Cooler # D15902 is both a transmission and oil cooler it would need to take the place of the cooler that you have. However this will likely provide less transmission fluid cooling than your existing external cooler. What I recommend for your 2007 Silverado (New Body) with 6.0 liter motor is to just add a small oil cooler only so that you will get the maximum benefit of both coolers.

    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...

But adding coolers will certainly be beneficial to you and help protect the transmission and motor for excessive heat.

    When towing a trailer, the vehicle will be working twice as hard as opposed to normal driving conditions and even more so when climbing a hill. The added workload is going to cause a buildup of heat which would affect both performance and wear lift. If the vehicle is as you put "overheating" and you are within the towing capacity of your truck, there is a problem in the cooling/oiling system and you will need to take the vehicle to a shop to have it looked over.

    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...
