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!

Easy straight forward install seems to work well

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.

  • Recommended Engine Oil Cooler for 2006 Ford F150 with 5.4L Motor
    Engine oil coolers are not vehicle-specific, but the Derale # D15405 Engine Oil Cooler Kit you referenced, part # D15405 would be compatible with the 22 mm x 1.5 mm filter landing and 2-3/4 filter o-ring diameter used by your 5.4L engine. 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. You will need to ensure that the 1-3/4...

  • Installing Oil Temp Sensor And Oil Cooler Kit On 2003 Ford Explorer
    I spoke with my contact at Derale and also with other Experts about your 2003 Ford Explorer options. The least expensive and probably easiest way to install your oil temp gauge sensor is to install an inline tee. If you choose to use the Derale kit, part # 15405, abd you want to use the oil temp gauge, you are going to need to find a tee that has 1/2 inch barbed ends and a 1/2 inch NPT female. You might be able to find the tee at a hardware store or possibly an auto parts dealer. If...

  • Will Derale Plate-Fin Engine Oil Cooler Kit # D15405 Fit a 2006 Chevy TrailBlazer 4.2 Liter
    Your 2006 Chevy TrailBlazer with the L6, 4.2 liter motor takes a n engine filter thread size of 13/16-16 and the O-ring diameter is 2-3/4 inches. Derale Plate-Fin Engine Oil Cooler Kit, # D15405, does include both of those items and others so it will fit your TrailBlazer. You may find that you will not have enough room for the regular filter. If you need a smaller one for space reasons you can use Fram filter PH3506 which is 3.36 inches tall.

  • Engine Oil Cooler for a 2000 Dodge Durango 5.2L SLT
    Yes, the Derale oil cooler, # D15405, will fit your 2000 Dodge Durango 5.2 liter. Your Durango should use 3/4-16 threads and a 2-3/4 inch diameter O-ring, both of which are included in this kit. The best place to route the hoses depends on where you end up mounting the cooler. If there is space in front of the A/C condenser behind the grille, you will want it there for the most efficiency. Off to one side of the radiator would be best so that you can route the hoses around the radiator...

  • Oil Cooler Recommendation for a 2011 Toyota Tacoma

  • Derale Engine Oil Cooler # D15405 Installation in 2009 Chevrolet Silverado LT 4WD
    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.

  • 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 much...

  • Does Installing an Engine Oil Cooler and Remote Oil Filter Require Adding More Oil
    You will need to add oil to compensate for the extra capacity of an oil cooler and filter on your 1994 Chevy K1500. These components will retain some oil when the engine is not running, much like your current oil filter, but it will not be to their full capacity. The remote oil filter can be mounted anywhere in the engine compartment.

  • 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 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.
