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.

Awesome product thanks

Fit truck well. Good quality.

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.

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.

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

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!



by:

This is a real nice kit. The oil cooler that was in the kit i receive had brackets on each side. The one picture online item # D15405 does not have it. Which was fine because the holes line up with a/c condenser on left side looking at it. Bolted it right on looks like it came factory install. Real please with it so far as lower oil temps down to 200 degrees when under a hard pull. Oil temp before kit was running at the highest was 255 degrees. Highly recommend this kit. The shipping was also fast.



by:

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!



by:

A local mechanic installed the cooler. The next day the oil line to it failed and we lost all of the oil. He fixed it, but again two days later it failed again and he removed the cooler and refunded our money. I through the cooler out. Can't trust the installation.



by:

Instructions were clear and installation was easy. Works great. Lower engine oil temps when towing. Shipping was quick too.



by:

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



by:

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.

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.

Easy straight forward install seems to work well

  • Transmission & Oil Coolers for 2015 Ford Explorer
    To get your 2015 Ford Explorer ready for towing you can add both a transmission cooler and an oil cooler if you want. We offer individual coolers that can handle either oil or transmission fluid, and also 2-core combination coolers that can handle both. For an efficient Class III transmission cooler I recommend Derale's kit # D13503. I linked an installation video showing this being installed in an Explorer. You'll install this cooler on the transmission's existing return line where it...

  • Recommended Engine Oil Cooler for 2015 Ram 1500 5.7L Engine
    For your 2015 Ram 1500, I recommend the Derale Plate-Fin Engine Oil Cooler Kit # D15405. This is a great plate-fin cooler that will reduce the oil temperature in your vehicle by up to 50 degrees. The dimensions on the unit are 9-7/8 inches wide x 9-1/2 inches tall x 1-1/4 inches deep. This kit will include the heat exchanger, hoses and a sandwich adapter that is compatible with the 22x1.5 filter landing on your 5.7L engine.

  • Derale D15405 or D15602 Oil Cooler for 2016 Ram 1500
    For your 2016 Ram 1500, between the Derale Plate-Fin Engine Oil Cooler Kit # D15405 and the Derale Stacked-Plate Engine Oil Cooler Kit # D15602, I highly recommend going with the latter, the stacked-plate kit. The reason why is that the stacked-plate kits are simply the most efficient oil coolers available, which means what they do is cool more fluid - and cool it faster - than the tube and fin or plate and fin coolers do. So the best option for your Ram to get the best cooling is definitely...

  • Engine Oil Cooler For a 2011 Ford F-150 With 3.5L EcoBoost Engine
    Yes, adding an Derale Plate-Fin Engine Oil Cooler Kit # D15405 will greatly help to reduce engine oil temperatures. With your 2011 Ford F-150 having the 2 turbochargers they are transferring a lot of heat into the engine oil as that is what lubricates and cools the turbos. This cooler is much larger at 9-7/8" Wide x 9-1/2" tall than the factory cooler to reduce the engine oil temperature much better. We also have the Derale Atomic-Cool Remote Engine Oil Cooler Kit w/ Fan # D15450 which...

  • 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.

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.

    I recommend taking a look at the Derale Plate-Fin Engine Oil Cooler Kit # D15405.

It includes multiple sleeve nuts to ensure proper thread size along with a sandwich adapter. It features 3/8 inch NPT inlet/outlet ports.

  • 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...

  • Tow Package Recommendation for a 2011 Ford Explorer
    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...

  • Recommended Engine Oil Cooler for a 1991 Chevy K1500 Pickup Truck with 5.7L Engine
    What you are looking for is an engine oil cooler with a sandwich adapter. This will leave the oil filter in its current location. Cooler # D15405 is an excellent choice. It does have a sandwich adapter and multiple thread and o-ring sizes. It looks like your 1991 Chevy K1500 with the 350 motor uses either a 2-3/4 inch or 3-1/2 inch diameter o-ring. This kit has both. And the truck also uses either a 18x1.5mm thread style (most likely) or a 13/16-16 inch thread style. The kit includes both. So...

  • 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...

    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...

  • 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.

  • 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.

    I'd recommend the Derale Plate-Fin Engine Oil Cooler Kit with Spin-On Adapter, # D15451. This kit comes with everything you need to install this cooler. It has the heat exchanger, a spin-on remote adapter, hoses, rings, etc. The plate-fin cooler gives you strength and efficiency. This oil cooler comes with a remote mount oil filter adapter, not the sandwich adapter. This allows you to mount the oil filter wherever you desire.

    This Derale Plate-Fin Engine Oil Cooler Kit # D15451 that you referenced will lower the engine oil temperatures of your 2011 Dodge Ram 1500 4x4. It is hard to say exactly how the temperature will decrease, but the more airflow the cooler will see the more the temperature will drop. If it would not drop to 180 degrees it would get pretty close. This # D15451 that you referenced does not have a thermostatic bypass.

  • Recommended Method for Cooling Engine of 2004 Chevy Trailblazer at Highway Speeds
    I have a solution for you. But at interstate speeds the fans of a radiator aren't really doing much cooling. The fans are generally only there for when the vehicle is at slower speeds. Adding a pusher fan would help if the problem was lower speeds but at interstate speeds it's not going to make a noticeable difference. What would work best is actually an oil cooler. This will cool your oil off at highway speeds and would make a noticeable different. Your 2004 Chevy TrailBlazer takes...

    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.
