Derale Accessories and Parts - D13302

  • Engine Oil Coolers
  • Transmission Coolers
  • Core
  • Derale

Efficient tube-fin core merges a 6-pass engine oil cooler with a 4-pass transmission fluid cooler for maximum benefit. Intended as replacement core for Derale combination transmission and engine oil cooler systems.


  • Can be used with any 2 automotive systems - transmissions, engines, fuel or power steering systems
    • Fluids flow through separate tubes inside the same core for effective, simultaneous cooling
  • Lowers fluid temperatures with heat-exchanging tube-fin construction
  • Designed with copper tubing expanded into aluminum fins for maximum heat transfer
    • Copper is the best material for conducting heat from the fluid, and aluminum is ideal for transferring and dissipating that heat
  • Protected from possible damage during installation by plastic fin guards
  • Functions as replacement part for Derale combination coolers:
    • Derale Combination Transmission and Engine Oil Cooler with Multiple Threads (D15902)
    • Derale Combination Transmission and Engine Oil Cooler for GM Applications (D15903)
  • Made in USA


  • Inlets: 11/32" hose barb and 1/2" hose barb
  • Overall dimensions: 16-13/16" wide x 12-5/8" tall x 3/4" deep
  • Core length: 13-7/16"
  • Distance between 6-pass inlets: 6-1/4"
  • Distance between 4-pass inlets: 3-3/4"
  • 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 Derale's 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.

  • Derale Tube-Fin Engine Oil Cooler Kit # D15503 Recommendation
    The most economically priced engine oil cooler we offer is the Derale Tube-Fin Engine Oil Cooler Kit # D15503, while is more expensive than the Derale Combination Transmission/Engine Oil Cooler # D13302 that you referenced it also includes all of the necessary fittings and adapters to install it on your vehicle that the # D13302 does not. I attached an FAQ article on engine oil coolers for you to check out also.

  • Transmission and Power Steering Coolers for a 2010 Honda Odyssey
    Transmission and power steering coolers are not vehicle specific, though sometimes some special fittings are needed. For your 2010 Honda Odyssey, you can use any transmission/power steering cooler that will fit in the engine compartment, see FAQ link. You could also use a combination cooler which uses the same core for 2 systems. The Derale cooler, # D13302, would be a good choice with install kit # D12006. The Air Duct that Honda refers to is something that gets mounted to the body of...

  • Radiator Adapter Recommendation for a Transmission Cooler Install on a 2003 Ford F150
    For the radiator side of the Derale Combination Transmission/Engine Oil Cooler Core # D13302 that will work as the transmission cooler you would want Derale Radiator Adapter Fittings # D13025. The sandwich adapter you purchase to go with the oil cooler side of the # D13302 should come with barbs to attach the rubber lines to. You might be interested in purchasing a Derale Thermostatic Sandwich Adapter Kit # D15782. This product has multiple thread sizes to that it should work on your...

  • Transmission Cooler Recommendation for 2012 Dodge Grand Caravan
    Because it uses a cartridge style oil filter instead of a spin-on type, the sandwich adapter required to install an oil cooler can't be used therefore we don't have an option to install an oil cooler for your vehicle. This being said, newer engines do a very good job keeping the oil cool already, so in all honesty a cooler isn't really needed on your vehicle. You could indeed benefit from a transmission cooler, though. The best place to install a cooler is directly in front of the radiator,...

  • Parts Needed to Install Derale Transmission/Engine Oil Cooler # D13302 on 2003 Ford F-150
    To properly install the Derale Transmission/Engine Oil Cooler # D13302 on your 2003 Ford F-150, you will need to purchase the hose separately. I recommend the Derale Single-Hose Transmission Cooler Installation Kit # D12006. I have provided a link to this product. Provided the Transmission/Engine Oil Cooler fits properly in your vehicle, you will also need the Derale Radiator Adapter Fittings # D13025 and I have provided a link to that product as well. For the oil cooler connection, I...

  • Best Solution for Lowering Vehicle Temperatures When Towing
    The added stress from trailer towing usually shows up as an increased transmission temperature. I am not sure if the gauge you're referring to is displaying engine coolant temperature or if you have one that shows transmission temperature. We do offer Derale Class III transmission cooler # D12903 for your 5.3L Yukon XL which measures a generous 15-1/4 x 7-1/2. This can be mounted in front of your AC condenser to provide supplemental transmission cooling after the OEM cooler in the radiator...

  • Acura MDX 2005 Transmission and Power Steering Fluid Cooler Recommendations
    Yes, the Derale Series 8000 Plate-Fin Transmission Cooler Kit, item # D13502, would be a good choice for your 2005 Acura MDX. I linked a drawing showing how the cooler will install and the best location for mounting the cooler on your MDX. You will need to measure the space in the front of your vehicle for mounting the cooler, to determine if this cooler will fit. Dimensions for all of our coolers are on the product pages. We also have a video of a transmission cooler install that should...

  • Are Transmission Engine Oil and Power Steering Coolers Needed For Towing with a 2007 Honda Pilot
    Since the manufacturer recommends these aftermarket additions for your Pilot, we cannot suggest differently. The thing to remember is that if you do add these items and a warranty issue comes up, you have shown that you took the proper steps to ensure that your vehicle would perform properly so warranty service should not be a question. Another thing to consider is that heat is the enemy of your engine, transmission, and power steering. Using a cooler will dissipate more heat and prolong...

  • Adding Combo Transmission and Engine Oil Cooler To 2006 Dodge Ram 2500
    The Derale Remote Engine Oil Cooler # D15752 that you referenced is pre-set to activate the fan at 180 degrees. It will automatically turn off the fan at 165 degrees. When looking for a combo cooler, the best cooler for your vehicle is generally the largest cooler that will fit in front of the radiator. The largest combo cooler we carry is the Derale Combination Transmission/Engine Oil Cooler # D13302. This cooler measures 16-13/16 x 12-5/8 x 3/4 inches. The next largest cooler is the...

  • Combination Transmission/Oil Cooler for 2010 Chevy Tahoe Towing Small TT from Arkansas to Alaska
    The Derale combination transmission/engine oil cooler # D13302 would be an excellent choice for you, if you have the space available directly behind the grille to accommodate its 16-13/16" wide x 12-5/8" tall x 3/4" deep size. If you need something a bit smaller, you can go with the # D13222 which measures 12-13/16" wide x 10-1/4" tall x 3/4" deep. For the transmission cooler circuit, you'd need the # D13064 hardware kit and the # D13035 fitting. For the oil cooler circuit, you'd need...

  • Installing Derale Combination Transmission/Engine Oil Cooler, Part # 13302, in a 2010 Honda Odyssey
    The Derale Combination Transmission/Engine Oil Cooler Core, part # D13302, offers the convenience of being able to cool two engine fluids within one single housing. The protocol for cooling engine fluids is generally to cool the engine oil as a first priority, followed by the transmission fluid, and then the power steering fluid. Coolers are not vehicle-specific, meaning that you can use the largest one that will fit in the space available in front of your air-conditioning system condenser....

  • Parts Needed to Tow a Trailer With a 2010 Honda Odyssey
    By all means, take your children camping! I took a look at the owner's manual for a 2010 Honda Odyssey and it looks like the maximum total trailer weight (the weight of your loaded trailer) you Odyssey can tow is going to depend on the number of occupants. According to the manual, the number of occupants is calculated at 150 lbs per person, so take that into account, though it seems likely your Odyssey will still have enough capacity for a 2,300 lb trailer, just be mindful of the amount...
