Derale Transmission Coolers - D15902

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

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.

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.

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.


Comments
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

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.

  • What Would Cause Transmission To Seemingly Stop Shifting Properly When It Warms Up
    I've had similar issues with cars and the problem wasn't that the temperature of the fluid was causing the change in shifting/performance the issue was that the fluid filter was getting clogged with debris (from clutches etc. failing and coming apart in the transmission) and therefore not able to allow the transmission to shift properly. Once you park the car the debris falls off of the filter and it appears to shift normal again till it clogs again. The solution is to take the vehicle...

  • How to Determine Towing Capacity of 2004 Dodge Dakota V8 4x4 Extended Cab
    Using my resources I was able to determine that your 2004 Dodge Dakota v8 4x4 with extended cab has a towing capacity of 4750-lbs when the rear axle has a gear ratio of 3.55; if your rear axle is geared with the 3.92 ratio you'll be able to tow up to 6050-lbs. Since your trailer is going to be near that limit you'll need to take into consideration whether or not any cargo that may be stored in the trailer when determining the gross towing weight. If this trailer is hauling a boat, you may...

  • Is Derale Transmission and Engine Oil Cooler D15902 Compatible With 2007 Honda Pilot EXL
    The combination transmission/oil cooler will work great on the 2007 Honda Pilot EXL.

The cooler will be the most efficient when installed between the grill and AC condenser. The cooler is 17" Wide x 12-1/2" tall x 3/4" deep. I have attached an installation video for your reference on a Toyota but the installation will pretty much be the same.

  • Towing Capacity for 1999 Ford Explorer with 4.0 Liter Engine
    I looked up the towing capacity of your 1999 Ford Explorer 4.0 liter and it looks to have a capacity of 4,799 lb so towing a 1,500 lb trailer would not be an issue at all. If you wanted to install an oil and transmission cooler like the Derale part # D15902 this wouldn't be a terrible idea at all, but it realistically wouldn't be absolutely necessary.

  • Will Derale Transmission Oil Cooler # D15902 Fit 2011 Ford Escape
    I was able to confirm that the oil filter thread dimensions of the 2011 Ford Escape do match the included filter thread size of 22 by 1.5 mm. If it's a clearance thing with the sandwich adapter but you have a solution that will allow it to fit I don't see why you'd have a problem. We have not had the chance to install this kit on a Ford Escape with a 3.0 though. The transmission side of the color is more of a universal style of install since it basically just installs after the factory cooler.

  • How to Reduce Engine Oil and Transmission Fluid Temperatures While Towing with a 2013 Ford F-150
    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.
