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 cooler used in this system is a highly efficient, radiator-style, plate-and-fin heat exchanger. In this system, finned chambers provide increased surface area for fluids to spread out while also continuously agitating them, resulting in superior heat transfer with minimum pressure drop.

Before I purchased this oil cooler, I was pulling my small boat loaded with camping gear over the willamette pass in oregon in the middle of summer. The temp outside was pushing 100 degrees and the road was a pretty steep grade uphill. My ram 1500 started singing with different bells and displayed engine temp was pushing 245 degrees. I started sweating bullets, hoping my engine wouldn’t blow up. After I got home I did some research and found this oil cooler. Hoping it would help and do the trick, I purchased it and hoped for the best. We went camping this year to the same location, and the entire way I was staring at all the temp gauges. My truck never got above 220 degrees. This thing works!

just one problem the sandwich adapter will not fit on a 2008 Avalanche 4x4 the front drive shaft is in the way had to modify

I put this in my 1981 Chevy C10. Toughest part was finding an oil filter that worked with the adapter but I did find one that worked just fine. I was concerned that my oil would be getting hot and I want to make my engine last a good long while so this was just a must. I can say after a long drive the oil entering the cooler is barely warm and the oil on exit is a little cooler than air temperature. This works perfectly and was not a problem to mount!

Great product quality, but the reason for the four stars and not five is because the hose barbs were miss packaged. I received four 3/8 NPT hose barbs but the two needed for the cooler are 1/2 NPT...a trip to Home Depot for the correct ones and $9.00 later was back in business.


Comments
The oil lines began seeping on a long trip coating the radiator with oil. Had to add multiple hose clamps to get it stopped. When I got back home, I replaced the fittings and oil lines with JIC connections and hydraulic hoses [about $100] Problem solved forever. Still a nice package just better now with a quality cooler and adapter.

The oil cooler works great, but you will need to order more hose because the amount given is not enough, you cannot find it at ANY auto parts store so order it the first time

Review from a similar Plate-Fin Cooler in Engine Oil Coolers


2009 GMC Yukon XL towing a 7,800lb travel trailer from California to South Carolina..... I don't believe the Yukon would have made this journey if it wasn't for the oil cooler and additional -to the stock- transmission cooler. Dragging the travel trailer through the mountains during the heat of the summer was taxing. However, my engine temp barely went past the 12 o'clock position and transmission never got above 190 F. Before installing these my engine temp would go to the 1-2 o'clock position and transmission temp would get up to 210 F. Highly recommend this product. Just make sure you have a filter that fits the adapter before installing. Just take the adapter to the auto parts store and find one that spins on it.

Review from a similar Plate-Fin Cooler in Engine Oil Coolers


Bought both the transmission cooler and engine cooler for my 2007 Chevy Tahoe. I'm a DIY'er cuz I hate paying for something I can do on a free weekend. Install was a breeze. Drop in temperature for the transmission was great. No more worries while pulling my trailer. Both quality products, both easy to install, and still working great with no leaks till this day.

  • 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.

  • Engine Oil Cooler Recommendation for 2014 Ram 1500 with 5.7 liter V8
    The Derale Stacked Plate Engine Oil Cooler part # D15405 is a really great option for an engine oil cooler for your 2014 Ram 1500 with a 5.7 liter V8. It's a larger stacked plate style of cooler which will do a great job lowering your engine oil temps when you are in the desert.

  • Engine Oil Cooler for 2013 Ram 1500
    It would be a good idea for you to use the Derale Plate-Fin Engine Oil Cooler Kit # D15405 and a 190 thermostat won't necessarily be needed with this because the Cooler Kit should reduce those temperatures enough. The Derale # D15405 is a plate and fin cooler, making it highly efficient because it consistently works to agitate the fluids. The can reduce your oil temp by up to 50 degrees and comes with a complete mounting kit to go in your '13 Ram 1500.

  • Can Oil Cooler On Ford F-250 Be Replaced With Derale Oil Cooler
    If the Fabic oil cooler on your F-250 is a separate oil cooler, then you can replace it with an oil cooler like part # D15405. The # D15405 comes with multiple sleeve nuts to ensure proper thread size. This plate-fin cooler is installed with the included sandwich adapter and comes with all the necessary hardware needed. I have attached a helpful article about oil coolers you can check out.

    Though the Derale Plate-Fin Engine Oil Cooler Kit w/ Adjustable Sandwich Adapter (Multiple Threads) - Class V # D15405 is a universal fit item, it will fit your 2014 Subaru Forester 2.5i Premium. Based on my research your vehicle has a 22mm thread, which is one of the filter thread sizes this kit comes with. This kit also comes with an O-ring and adapter plate, though the adapter is generally used for some model year GM vehicles and unlikely to be used in your Subaru. I have added a...

  • Are Engine Oil Coolers Fits for 2017 Subaru Outback
    Engine oil coolers can fit any vehicle so long as there is room for it to install. So the best oil cooler, the Derale Hyper-Cool Remote Engine Cooler Kit # D15660 measures 13" wide x 10" tall x 5-5/8" deep so you'd need that much room in your 2017 Subaru Outback. The larger the cooler, the better the cooling, so if you can fit this cooler in I recommend it, otherwise there is the 9-7/8" wide x 9-1/2" tall x 1-1/4" deep Engine Oil Cooler Kit # D15405 you mentioned which is also a very...

    There are a few items I would recommend so that you can tow safely with your 2011 Ford Explorer. First let's start with a hitch. For that the Draw Tite Hitch part # 76034 would be an excellent choice. I attached an install video for you to check out. For ball mounts I recommend the etrailer Ball Mount Kit # 989900. It comes with 2 ball mounts, 2 balls, a hitch pin with clip, and a carrying bag. For trailer wiring you will want the Curt Wiring Harness part # C56093. Your Explorer has...

  • Will Derale Combo Transmission and Engine Oil Cooler # D15903 Fit 2005 Chevy Silverado LT 5.3L V8
    In normal conditions I think that the Derale Combination Transmission and Engine Oil Cooler, # D15903, would work fine for your 2005 Chevrolet Silverado, but since you mention the Mojave Desert, this is going to be a different story. With excessive desert temperatures, it is going to take quite a bit more to cool the transmission fluid and engine oil. In this case I would use 2 separate coolers and go with the largest ones possible. Of course you will want to take a measurement to see...

  • Best Engine Oil Cooler for 2015 Ram 1500 5.7 Liter
    Both the Derale # D15405 and # D15602 are great options for your 2015 Ram 1500. Since engine oil coolers are not vehicle specific, either cooler will work well for you. The # D15602 is a stacked-plate design which generally cools faster and more efficiently, which is why it's able to be so much smaller. In terms of efficiency, the stacked-plate design is the best at cooling the engine oil. This oil cooler measures 13 inches wide by 4-9/16 inches tall by 2 inches deep. Since it's smaller...

  • Will Derale Plate-Fin Engine Oil Cooler Kit Fit a 2014 Ford Flex
    The Derale Plate-Fin Engine Oil Cooler Kit w/ Adjustable Sandwich Adapter (Multiple Threads) - Class V # D15405 is a universal fit with 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 engine filter thread sizes so it will have no problem working with your 2014 Ford Flex, the latter of which I believe is the appropriate one for your vehicle. I have added a link to the installation instructions for you as well, which I recommend checking out.

  • Engine Oil Cooler and Pressure Gauge Recommendation for a 2008 Chevy Silverado
    According to Derale, the 5.3 liter engine used in 2007 and 2008 uses a filter thread size of 22 x 1.5mm and an O-ring size of 2-3/4 inches. The Derale Engine Oil Coolers # D15405 is compatible with oil filters with those dimensions so it would work well for you. The easiest way to run an oil pressure gauge would be to use the info that is present at your OBDII port by using an Insight part # EP84030. Running a pressure gauge off of the sandwich adapter is not something we would be able...

    The factory tow package included the trailer hitch, wiring harness although not fully connected, and engine oil cooler. All automatic Escape models have a transmission cooler as well. If you want to add a piece by piece towing ability, I recommend starting with the Draw-Tite Max-Frame 2" trailer hitch # 75118. Then add the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118343 which plugs into your factory wiring connections behind your tail lights. You will also want...

  • Engine Oil Cooler Recommendation for a 2008 Chevy Silverado with 5.3 Liter V8
    The adapter for the oil filter on the part # D15405 comes with several threads that will adapt to what your block has on it. The adapter plate of this is designed to fit vehicles that have a 3-1/2 inch filter landing. This was primarily designed to fit GM small block and big block V8 from 1963-2007 so it would work well for you.

  • Oil Cooler for 2018 Subaru Forester with CVT Transmission & 2.5 L Engine
    You definitely can add an oil cooler to your 2018 Subaru Forester without voiding the warranty as you are protected under the Federal Magnuson-Moss Warranty Act. The Act states that if something breaks on your vehicle and you take it in for warranty repair, the dealer must honor your warranty unless whatever modifications you have added to your vehicle actually caused the problem in question. The temperature of 240 degrees is actually pretty ideal especially for towing so you don't necessarily...

  • PSI Pressure through the Sandwich Adapter and is Flow Lost in Engine Oil Cooler Kit # D15405
    I spoke with my contact at Derale regarding the Engine Oil Cooler Kit, # D15405. He stated that typical pressure through the sandwich adapter on a vehicle at 3,500 RPM is 50 to 60 psi on a normal system and up to 90 on a high flow/high volume system. The adapter itself can easily manage that amount of pressure. He went on to state that any time a component like this is added to a system there will be some flow loss and oil pressure lost but with this system, it will be a minute loss and...

It has the heat exchanger, a spin-on remote adapter, hoses, rings, etc. The plate-fin cooler gives you strength and efficiency.

This cooler has furnace-brazed aluminum construction and 3/4 inch turbulator plates for more efficient cooling. It comes with the complete mounting kit and measures 11 wide x 8-3/4 tall x 7/8 inches deep. This will give you more than enough room to also add an oil cooler.

    An engine oil cooler with fan, like # D15450, has a 10 foot OEM spec hose. Provided that you are within the range of the hose you should not see any significant change in oil pressure or flow when using this kit. Because this system has its own fan, it can be mounted anywhere that you have space in the engine compartment.
