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.

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! 635897

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. 400824


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.

  • Will Derale Plate-Fin Engine Oil Cooler Kit Fit 2014 Subaru Forester 2.5i Premium
    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...

  • 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...

  • 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.

  • Recommendation for Engine Oil Cooler in a 2017 Ram 1500 5.7L
    If you are strictly looking for an oil cooler then I recommend the Derale Plate-Fin Engine Oil Cooler Kit # D15405 which is a Class V plate-fin cooler so it is very efficient. It includes an adjustable sandwich adapter and multiple threads to ensure that it fits properly. This cooler measures 9-7/8" wide x 9-1/2" tall x 1-1/4" deep so you just need to mount it in a place where it will get the max amount of airflow, like between your grille and the AC condenser core.

  • Hose Length in a Derale Remote Engine Oil Cooler and How Far from the Engine Can it be Mounted
    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.

It also comes with the proper filter thread size which will be 13/16-16, 18 mm x 1.5 mm, or 22 mm x 1.5 mm. Going with a combination cooler for oil and transmission fluid is not a bad idea.

  • 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.

  • Will an Oil Cooler Kit Fit a 2013 Toyota Highlander with the 3.5L V6 Engine
    Your 2013 Toyota Highlander with the 3.5L v6 engine uses a cartridge style oil filter which means the Derale Plate-Fin Engine Oil Cooler Kit part # D15405 will not work for you. With that being said, it is unlikely that you would need an oil cooler if you are within the towing capacity. In most newer vehicles, installing an engine oil cooler can have a negative impact as they actually cause a decrease in oil pressure. The decreased oil pressure is not drastic but does have more of an affect...

In order to install the return line of the sandwich adapter you will need to use Derale 3/8" NPT Female x 3/8" NPT Male 90-Degree Hose Fitting part # D98333.

    Engine oil coolers are not vehicle-specific so you can use as large a cooler as the space you have available to install it. The Derale # D15405 engine oil cooler is a highly-efficient Class V plate-fin cooler that measures 9-7/8- wide x 9-1/2- tall x 1-1/4-inches deep. If you have room in front of your A/C condenser to install this then it is an excellent choice.

  • Is There Risk of Oil Lines from Derale Oil Cooler # D15405 Blowing Out From Oil Pressure
    Reinforced rubber oil lines and steel ring clamps are supplied with most oil coolers. This type of hardware is more than adequate for such applications. Even a high-volume oil pump will not even begin to approach the burst point for such hoses, which are rated at 300 psi. Keep in mind that as the oil cooler reduces your oil (and engine) temperature the thermal stress on all oil lines (and coolant hoses) will be reduced to some degree. The reduction in oil temperature, which can be as...

  • Recommended Transmission/Oil Cooler for 2006 Ford F150 w/ 5.4L Engine
    A combination oil/transmission cooler isn't a vehicle specific item. The best place to install a combo cooler is directly behind the grille in front of the radiator/AC compressor. You'll need to choose a cooler that will fit in the available space. I'd recommend the # D15902 kit which has a condenser that measures 17 x 12-1/2. Your 5.4L engine would need the # D13025 fitting kit, but everything else needed is included in the kit.

The 9-7/8 tall by 9-1/4 wide by 1-1/4 thick cooler is very efficient and would be an excellent choice for you, assuming you have the proper space for the cooler directly behind the grille in front of the radiator.

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.
