Derale Engine Oil Coolers

  • Tube-Fin Cooler
  • Class III
  • With 1/2 Inch NPT
  • Derale
  • 16-5/8W x 7-5/8T x 3/4D Inch
  • W/ Spin-On Adapter

16-5/8" Wide x 7-5/8" tall x 3/4" deep, efficient, tube-and-fin cooler core comes with a spin-on adapter and all necessary installation hardware, making it easy to prolong the life of your engine and improve its overall performance.


Features:

  • Prolongs life of engine oil, reducing number of necessary changes
  • Improves overall functioning and performance of engine
  • Reduces oil temperature by as much as 50 degrees to maintain optimum temperature
  • Cools effectively through use of efficient, tube-fin core
  • Provides external lines for heat exchanger via spin-on adapter
  • Includes:
    • Tube-and-fin cooler core
    • Ports-up filter mount
    • Spin-on adapter
    • High-temperature, high-pressure rubber hose with stainless steel clamps
    • Multiple fittings to ensure proper engine thread size
    • Brass hose-barb fittings
    • Mounting hardware
  • Made in USA


Specs:

  • Heat exchanger:
    • Dimensions: 16-5/8" wide x 7-5/8" tall x 3/4" deep
    • Distance between inlets: 6-1/4"
    • Core width: 13-7/8"
  • Spin-on adapter:
    • Inlet/Outlet ports: 1/2" NPT
    • Filter thread: 3/4"-16
    • O-ring diameters: 2-1/2", 2-3/4" and 3-1/2"
  • 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. The result is longer-lasting oil and a better-functioning engine.

The spin-on adapter in this kit allows for the external oil lines necessary to install an engine cooler by converting your vehicle's oil-filter landing into a passageway. Because the adapter mounts where your filter normally is, you will have to use the mount provided to move your oil filter to another location.

To start I gave the product a good rating only because the kit put together by Derale came with the wrong barb fittings. I called Derale directly and they sent out the right fittings. I have not installed the kit yet but it is well made in the USA. If the kit would of came with the proper barb fitting definitely would of got a excellent rating. 73145

Ask the Experts about this Derale Engine Oil Coolers

  • Oil Cooler that Fits 2013 Ram 1500 with 5.7 liter Hemi
    I did some checking and your 2013 Ram 1500 with the 5.7 liter Hemi has oil filter threads that are M22x1.5 which means that for a cooler kit you'd want the # D15405 which includes a fitting that matches this size. The cooler that comes with this is a plate-fin style cooler which is incredibly efficient so it will do a great job keeping your oil as cool as possible.

  • What Size Oil Filter Needs To Be Used After Installing the Derale Tube-Fin Engine Oil Cooler Kit
    Once the Derale Tube-Fin Engine Oil Cooler Kit part # D15551 is installed, you can use any oil filter with 3/4"-16 threads. For this, we have the Replacement Filter for Derale Remote Transmission Filter Kits part # D13092 or you can use any of the ones in the attached photo.

  • Oil & Transmission Coolers for Ford F-53-Based Class A RV
    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. Derale Class III cooler # D15551 includes a spin-on adapter in the required 3/4-16 thread. This will be a good choice...

  • Recommendation of Transmission and Oil Cooler For a 2008 Chevrolet Suburban 1500 4WD
    If you have enough room in front of your air conditioning condenser or in front of your radiator on your 2008 Chevrolet Suburban 1500 4WD, I would recommend the Derale Combination Transmission and Engine Oil Cooler, part # D15902. This is a combination transmission and engine oil cooler that will keep both engine and transmission temperatures cool with just one system. It measures 17 inches wide x 12-1/2 inches tall x 3/4 inch deep. You will also need the Derale Snap-In Radiator Adapter,...

  • Engine Oil Cooler Kit for 2017 Ram 1500
    The Derale Tube-Fin Engine Oil Cooler Kit w/ Spin-On Adapter (Multiple Threads) # D15551 is not a vehicle-specific fit. It will work for your 2017 Ram 1500 so long as you have the required space to mount it; the heat exchanger is 16-5/8" wide x 7-5/8" tall x 3/4" deep so as long as you have that amount of space it will work for you.

  • Transmission and Oil Cooler Recommendations for 2008 Dodge Caliber
    If your CVT transmission has lines that run from the transmission to the radiator (some do, some do not), you can install a transmission cooler. A transmission cooler is inexpensive insurance that would do a great job of extending the life of your transmission. If this is the case, a combination transmission/oil cooler would be a good choice. The Derale Combination Transmission and Engine Oil Cooler, part # D15902 might be a good choice for you. The Cooler Kit includes everything necessary...

  • Recommended Engine Oil Cooler for 2010 Dodge Challenger
    Based on my research, it looks like your Dodge Challenger uses the 3/4"-16 filter thread size, so the spin-on adapter that is included with the Derale Tube-Fin Engine Oil Cooler Kit # D15551 that you were looking at will actually work perfectly. I do recommend confirming this on your vehicle, as its possible you have a different model. This cooler kit also includes the high-temperature, high-pressure rubber hose with stainless steel clamps. This is a really nice, tube-and-fin cooler...

  • Engine Oil Cooler Recommendation for a 2001 Dodge Ram with 360 Cubic Inch Motor
    The engine oil temperature should only be a concern if you notice that the gauge, if you have a gauge, is above the normal operating temperature. It can also be a concern when towing or carrying things in the bed of the truck. Adding an engine oil cooler will lower the temperature by as much as 50 degrees depending on where the core is mounted. Engine oil temperature should be between 180 and 200 degrees for the engine to function the best so if your engine oil routinely goes above that...

  • Does Derale Oil Cooler Use a Thermostat
    The Derale Tube-Fin Oil Cooler # D15551 does not use a thermostat. The filter installs inline with the oil lines and a thermostat will block the flow of oil until the specific temperature is reached. Depriving your engine of oil is certainly not something you want to do. The Derale cooler is a great choice for your 2014 Ram 1500. It will cool the engine oil, prolonging the life of your engine, without over cooling in low temperatures.

  • Oil Drip from Unidentified Small Cooler Attached to Transmission on a 2006 Chrysler 300
    It sounds like it could be a transmission cooler. What you can do is when the vehicle is cold, start it up and place it in drive for about 10 seconds or so. Then return it to park and turn off the motor. Feel the hoses and if one is noticeably cooler than the other then it is a transmission cooler. Coolers are normally found inside of the radiator. It is possible that someone has installed a supplemental one on the vehicle if there were other owners before you. If it looks like # D13260...

  • Engine Oil Cooler and Transmission Cooler Recommendations for a 2006 Chrysler Town and Country
    Because there is not a lot of space in the engine compartment on a lot of vehicles, I usually gravitate towards a smaller stacked plate cooler because they take up less space. For your 2006 Chrysler T and C, I recommend the Derale Stacked-Plate Engine Oil Cooler Kit, # D15602. This cooler measures 13 inches wide, 4-9/16 inches tall, and 2 inches deep. It comes with multiple engine thread types so you will just need to use the one that fits your specific engine size. For a transmission...

  • What is the Additional Oil Capacity from Adding Derale Oil Cooler # D15551
    My contact at Derale advised that the approximate additional oil capacity resulting from the installation of their oil cooler # D15551 will be in the vicinity of 7 - 8 fluid ounces. This can vary depending on the length of the oil lines since some vehicles/installations may use all of the supplied hose while others do not. It is always best to check your dipstick to ensure you are operating your vehicle with the correct amount of engine oil.

  • Recommended Oil Cooler for a 2005 Chevy Trailblazer 4.2 Liter I-6 Engine
    There are three basic types of heat exchangers. Tube and fin, plate and fin and stacked plate. Stacked plate being the most efficient. Take a look at the informative article about oil coolers I included. The cooler I recommend is the Derale stacked plate oil cooler kit with Sandwich adapter # D15602 because it's super efficient and one of our most popular ones we currently offer. It will reduce oil temps by as much as 50 degrees. The external lines via the sandwich adapter makes installation...

  • 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...

    I did some checking and it looks like the oil filter threads on your 2013 Ford Explorer with a 3.5 liter engine are M22x1.5 mm, so you are going to need an oil cooler that is compatible with this. I would recommend you get the Derale Stacked-Plate Engine Oil Cooler Kit part # D15602. This kit comes with a compatible oil filter sandwich adapter so that it will work for you. This cooler is a stacked plate cooler, which of all the different styles of coolers this is the most efficient. Here...

  • 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 recommend Derale Tube-Fin Engine Oil Cooler...

  • How to Install a Derale Engine Oil Cooler, Part # D15505, in a 1970 to 1974 Hotrod
    Engine oil coolers are not brand- or model-specific; you can install an oil cooler as large as the space you have available to mount one, which is generally in front of the radiator and/or air-conditioning condenser on vehicles so equipped. With coolers, larger is better. This particular kit is intended for vehicles with an engine block oil filter landing between 2-3/4 inches and 3-1/2 inches. If your vehicle oil filter landing falls outside this range you will need to select an alternate...

  • Value of Installing a Power Steering Cooler on 2005 Honda Odyssey That Will Not be Used to Tow
    There is almost always a value in reducing the operating temperatures of the fluids in a vehicle. This is particularly true when it will bear the burden of towing, but it remains true for vehicles like yours that will not tow a trailer. The climate in your area may also play a role in determining the merits of a power steering, oil or transmission fluid cooler. In areas with high outside temperatures, fluid coolers are often considered essential by many drivers. I have included a link to...

  • Can an Oil Cooler and Filter Relocation Kit be Used Together
    Yes, you can use the Derale Oil Filter Relocation Kit # D15748 with an oil cooler. The cooler should be placed so that the oil goes through the cooler last. The addition of an oil cooler and the hoses for it will increase the amount of oil you will need so be sure to check the oil after installation and add however much is needed. You could use kit # D15551 which is a cooler and it has the relocation parts all in one kit. We installed this set up on a co-worker's truck. I have linked...

    The Derale Engine Spin-On Adapter Kit w/ Dual Side Ports, # D15746, is not vehicle specific, so it may fit your 1991 Dodge Caravan as long as the oil filter thread size is 3/4 Inch-16. If you are looking for a spin on adapter, you would need to use Derale Engine Spin-On Adapter Kit, # D15747, which has adapters for engine filter thread sizes 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.

  • Recommendation for an Oil Filter Adapter for Installing an Oil Cooler on a 2006 Pontiac GTO
    The low profile sandwich adapter, item # D25771, is 1 inch thick. If you know the thread pattern on your engine oil filter the 13/16-16 threads may work but a universal kit is what we normally recommend, so you have the correct adapter for your application. This kit is the Low-Profile Sandwich Adapter - Multiple Engine Filter Threads, item # D25783. I would not recommend using a shorter oil filter with less capacity than the OEM oil filter. It sounds like you want to install an oil...

    Thanks for asking about a Power Steering Cooler and Engine Oil cooler for your 2007 Toyota 4Runner SR5 V6. Adding two more coolers is not going to present a cooling issue for your engine/radiator. The coolers allow air to flow through them and will not transfer enough heat to the air going through them to effect the cooling performance of the vehicle's radiator. Your engine oil filter has 3/4-16 threads. So you can determine the correct threads to use from the recommended kits below,...
