The stacked-plate heat exchanger included is the most effective type of oil cooler, primarily because of its increased surface area. Allowing fluid to spread out over this larger surface area decreases the time required for heat transfer to take place, resulting in ultimate efficiency.

The sandwich adapter in this kit provides the external oil lines necessary to install a cooler without requiring you to move the factory spin-on oil filter, making it even easier to extend the life of your vehicle's engine. In addition, the thermostatic bypass feature allows oil cooler than 180 degrees to bypass the heat exchanger, so your engine will warm up faster.

    The Derale Stacked-Plate Engine Oil Cooler Kit # D15605 that you referenced will work great on your 2011 GMC Yukon with the 5.3L engine. Based on my research your Yukon's oil filter has a 22 mm x 1.5 mm thread size with which the included sandwich adapter is compatible. This stacked-plate cooler will do an excellent job of reducing the oil temperature with its large surface area and furnace-brazed aluminum construction to improve its lifespan and performance.

  • Engine Oil Cooler for a 2018 Ford Explorer with 3.5 Liter Engine
    I looked up the oil filter thread design of your 2018 Ford Explorer with a 3.5 liter engine and since it uses the M22 x 1.5 thread spec you'd want the # D15605 that you referenced as this comes with that size fitting.

  • Engine Oil Cooler Recommendation for a 2008 Toyota Sienna
    Oil coolers are not vehicle specific so you can mount anyone that will fit in the space available in the engine compartment. It looks like the 2008 Toyota Sienna could have either a 2-1/2 inch diameter or 2-3/4 inch diameter o-ring and it has 3/4-16 threads for the oil filter. For this set up I recommend Oil Cooler # D15451. It comes with everything you will need for installation including a spin on adapter that fits in place of the oil filter and a remote mount to relocate the filter to...

  • Best Engine Oil Cooler Recommendationfor 2013 Ram 1500 with 5.7 Liter Engine
    The oil cooler I would recommend for your 2013 Ram 1500 with a 5.7 liter that is confirmed to fit your oil filter would be the Derale Stacked-Plate Engine Oil Cooler Kit # D15605. Your oil filter has M22x1.5 threads and an outside diameter of 3 inches which is compatible with this kit.

I attached an FAQ article on engine oil coolers for you to check out as well.

  • Efficient Engine Oil Cooler on 2014 Ram 1500 5.7L
    A stacked plate cooler is going to be the most efficient cooler and they're usually smaller giving you more options on installation. In addition, a cooler that includes a fan, like # D15660, can be installed anywhere in the engine compartment since it provides its own air flow. For another option that does not include a fan, # D15605 is our most popular stacked-plate cooler. It will need to installed in a location that provides the most amount of airflow possible. Preferably in front...

  • What Is the Difference Between the Derale Stacked-Plate Engine Oil Cooler Kit D15602 and D15605
    The difference between the Derale Stacked-Plate Engine Oil Cooler Kit part # D15602 and part # D15605 is that the former comes with a 2-3/4" o-ring and the latter comes with both a 2-3/4" o-ring and a 3-1/2" o-ring. These o-rings are used to attach the sandwich adapter to the engine block (see photo). The 3-1/2" o-ring is only needed for 1963-2007 GM small block & big block V8 engines.

  • Transmission and Oil Cooler Recommendations for a 2011 Honda Accord Crosstour
    Congratulations on the new car. I will be happy to help you find some coolers that will fit your needs. For a transmission cooler, you can go with something small that will not take up a lot of space. I recommend the Derale Series 9000 Plate-Fin Transmission Cooler, # D13611, which measures 11 inches across, 3-7/8 inches tall, and 1-1/4 inches deep. This cooler is rated for up to 2,000 pounds so it would work well for your application. For an oil cooler, I recommend the Derale Stacked-Plate...

  • Important Temperatures to Monitor When Towing and How to Lower the Temperatures If Needed
    The key temperatures to monitor when towing are the transmission fluid, engine oil and coolant temperatures. Each of these fluids will have different ranges that you will want to stay within. For transmission fluid, the ideal operating temperature is between 160 and 200 degrees. If you find that you are running over 200 degrees, I would recommend installing a supplemental transmission cooler, like part # D13504, if you do not already have one. I also recommend using the Ford radiator...

  • Installing Oil Cooler in 2004 Ford Escape to Maximize Towing Capacity
    I did some online research, and from what I read, it seems that the 2004 Escape will already have a transmission cooler if it's equipped with an automatic transmission. I saw several references that stated the Ford 'Tow Package' for that vehicle included the hitch, trailer wiring and an oil cooler. As a first step, I'd confirm that your Escape has the tranny cooler. Look for a smaller heat exchanger (radiator) mounted directly behind the front grille of the vehicle, that's probably about...

    The Derale Stacked-Plate Engine Oil Cooler Kit w/ Sandwich Adapter (Multiple Threads) - Class III, item # D15605, will work on the 2008 Dodge Caliber SRT. The engine filter thread size is one of two sizes on the caliber,3/4-16 or 20 mm x 1.5mm, so you will need to determine which (included) sleeve nut will be used.
