Derale Engine Oil Coolers - D15551

  • Tube-Fin Cooler
  • W/ Spin-On Adapter
  • With 1/2 Inch NPT
  • Class III
  • Derale
  • 16-5/8W x 7-5/8T x 3/4D Inch

16-5/8" Wide x 7-5/8" tall x 3/4" deep, efficient, tube-and-fin cooler core comes with a spin-on adapter and all necessary installation hardware, making it easy to prolong the life of your engine and improve its overall performance.


Features:

  • Prolongs life of engine oil, reducing number of necessary changes
  • Improves overall functioning and performance of engine
  • Reduces oil temperature by as much as 50 degrees to maintain optimum temperature
  • Cools effectively through use of efficient, tube-fin core
  • Provides external lines for heat exchanger via spin-on adapter
  • Includes:
    • Tube-and-fin cooler core
    • Ports-up filter mount
    • Spin-on adapter
    • High-temperature, high-pressure rubber hose with stainless steel clamps
    • Multiple fittings to ensure proper engine thread size
    • Brass hose-barb fittings
    • Mounting hardware
      • (1) 3/4"-16 Hex sleeve nut
      • (1) 13/16"-16 Hex sleeve nut
      • (1) 18 mm x 1-1/2" hex sleeve nut
      • (1) 20 mm x 1-1/2" hex sleeve nut
      • (1) 22 mm x 1-1/2" Hex sleeve nut
  • Made in the USA


Specs:

  • Heat exchanger:
    • Dimensions: 16-5/8" wide x 7-5/8" tall x 3/4" deep
    • Distance between inlets: 6-1/4"
    • Core width: 13-7/8"
  • Spin-on adapter:
    • Inlet/Outlet ports: 1/2" NPT
    • Filter thread: 3/4"-16
    • O-ring diameters: 2-1/2", 2-3/4" and 3-1/2"
  • 1-Year warranty


Perhaps the simplest type of heat exchanger, the tube-fin effectively cools a variety of automotive systems. The concept is simple: Fluid cools as it travels through the core by transferring heat out to the fins. The fins then provide the surface area necessary for sufficient heat exchange to take place, allowing the heat pulled from the fluid to dissipate into the surrounding air. The result is longer-lasting oil and a better-functioning engine.

The spin-on adapter in this kit allows for the external oil lines necessary to install an engine cooler by converting your vehicle's oil-filter landing into a passageway. Because the adapter mounts where your filter normally is, you will have to use the mount provided to move your oil filter to another location.

It has been 1 year now. Here is the story.

Dodge
Ram 1500 5.7 w/3.92 gears.

Oil temp at speed with no trailer: 224
Oil temp at speed with Springdale Mini RV: 240 (backed off at that point….it would have kept climbing)

After the install:

Oil temp at speed with no trailer: 200ish.
With trailer 210-220

Before I did this, I had to keep it at 55 in the expressway to keep my oil from turning into charcoal. Now I can drive normally. Only at the hottest part of the summer on a long grade did I ever brake 230 and it cooled right back off at the top of the hill.

Also holds about another quart of fluid which I like from a wear/tear perspective.

Even if the temp wasn’t an issue this kit would be worth it to move the oil filter to a non-retarded spot. I opted to go with the frame on the right side. Can change filter from side if wheel is turned. Very nice.

Before I bought this, I read some reports about oil leaks. It took some time but this fate befell me as well. The oil filter adapter plate is not well designed and the fittings leak no matter what. I fixed it twice and spent $1200 having dealerships fix it twice. I eventually cut the hose to the adapter, hooked them together and put an OEM oil filter back on. Wish I had never even tried. What a mess....What a pain...what a waste of money and time. If you have a RAM and you are overheating your oil, buy a bigger truck. That is what I am going to do. No more half measures. F350 time.



by:

My vehicle is a 2010 Ram 1500 5.7 Hemi 4x4. Overall product is great, those Conti hoses are awesome and little hard to get on lol but only issue I had I couldn’t retain my factory mopar oil filter which isn’t a big deal I got a WIX filter that fit. Thanks for quick shipping and great product! Will be buying a transmission cooler from you soon!



by:

Installed this on my 2012 Jeep Grand Cherokee overland with the hemi as the oil temp was heating up while towing. The install was not fun as I had to remove the front fender, grill and under body shield. Had to relocate oil filter to driver side and as a result, ran out of hose and had go out to buy more. Wish there was a few more feet. I placed oil cooler in front of radiator.

Once installed, oil cooler has worked great as I regularly go off-roading and camping towing a 6k pound trailer. Oil temps stay 20-30 degrees cooler making a huge difference when towing. No issues with the oil cooler after a year of use. Has been a great product, I would recommend it.



by:

To start I gave the product a good rating only because the kit put together by Derale came with the wrong barb fittings. I called Derale directly and they sent out the right fittings. I have not installed the kit yet but it is well made in the USA. If the kit would of came with the proper barb fitting definitely would of got a excellent rating.

Recieved item on time, great quality.

Installed this product on my 2013 Ram 5.7 Hemi. Install was simple and straight forward. I hoped there would be improvements in the operating temperature of my engine oil, which there was. Now towing my trailer is no worry about engine oil temp. This cooler works exactly as advertised, and the temp never go above 220. An unexpected result was better gas mileage by almost 2 additional miles per gallon. Also the truck runs much quieter than before and smoother. This noticed by my wife who rides with me always. So I would defiantly call this a win win install and purchase.



by:

It doesn't fit my car even though the website said it would. I had already installed the radiator component before i found the filter adapter didn't fit so i couldn't return the product.



by:

Easy to install but make sure you use quality thread tape. Check for leakage after 300 miles of driving. Then check again.



by:

I purchased this kit 1 year ago for an 08 Toyota Highlander V6 Sport. The vehicle had a small (and I mean small) trans cooler already installed with the sport, but adding this additional cooler gives us the piece of mind an confidence that when either towing or evening just sitting in temps up to 116F at the drive through in SoCal during summer hours, my family will stay cool. The fans run less and the whole vehicle runs a bit cooler as well. I have verified this with 3rd party OBD readers, actively watching oil temps both at normal operating temps, hill climbs, towing, and when sitting in extreme heat. IT DOESNT BUDGE! I dont have enough good things to say about this cooler. If youve ever thought about it, you should do it. Very easy to install and it flat out works.



by:

This is a quality product and performs great. Installed on a 2012 Toyota Tacoma and had to have some machine work accomplished and a change from the original oil filter. Installation was straight forward after those issues were resolved.



by:

just what i needed easy install nice quality



by:

Happy to find a system with the adapter. Mounted to my 4runner very easily. Not much confidence in the plastic mounting method will make something else.



by:

Great product. Easy installation.

Bill is very knowledgeable and answered all my questions. Good fella, I can't comment on the product yet because I haven't installed it yet. Thanks Jesse

  • Recommended Engine Oil Cooler for 2010 Dodge Challenger
    Based on my research, it looks like your Dodge Challenger uses the 3/4"-16 filter thread size, so the spin-on adapter that is included with the Derale Tube-Fin Engine Oil Cooler Kit # D15551 that you were looking at will actually work perfectly. I do recommend confirming this on your vehicle, as its possible you have a different model. This cooler kit also includes the high-temperature, high-pressure rubber hose with stainless steel clamps. This is a really nice, tube-and-fin cooler that...

  • What is the Additional Oil Capacity from Adding Derale Oil Cooler # D15551
    My contact at Derale advised that the approximate additional oil capacity resulting from the installation of their oil cooler # D15551 will be in the vicinity of 7 - 8 fluid ounces. This can vary depending on the length of the oil lines since some vehicles/installations may use all of the supplied hose while others do not. It is always best to check your dipstick to ensure you are operating your vehicle with the correct amount of engine oil.

  • Power Steering Fluid Cooler For Motorhome On F53 Chassis
    The Derale Tube-Fin Engine Oil Cooler Kit w/ Spin-On Adapter (Multiple Threads) - Class III # D15551 that you were looking at is a universal cooler that can be used for engine oil, power steering fluid, or transmission fluid. It is a very popular option and would work well on your F53 motorhome as long as you have room for it: 16-5/8" Wide, 7-5/8" tall, 3/4" deep. This kit comes with multiple fittings to ensure proper thread size. I attached a demonstration video for you.

  • Engine Oil Cooler Kit for 2017 Ram 1500
    The Derale Tube-Fin Engine Oil Cooler Kit w/ Spin-On Adapter (Multiple Threads) # D15551 is not a vehicle-specific fit. It will work for your 2017 Ram 1500 so long as you have the required space to mount it; the heat exchanger is 16-5/8" wide x 7-5/8" tall x 3/4" deep so as long as you have that amount of space it will work for you.

  • Does Derale Engine Oil Cooler # D15551 Come with Thread Size for 1999 Ford F-150 5.4 Liter
    You are correct, the Derale Engine Oil Cooler Kit part # D15551 that you referenced does come with the correct M22x1.5 thread size that your 1999 Ford F-150 with a 5.4 liter engine comes with so it would work great for you.

  • Does Derale Oil Cooler Use a Thermostat
    The Derale Tube-Fin Oil Cooler # D15551 does not use a thermostat. The filter installs inline with the oil lines and a thermostat will block the flow of oil until the specific temperature is reached. Depriving your engine of oil is certainly not something you want to do. The Derale cooler is a great choice for your 2014 Ram 1500. It will cool the engine oil, prolonging the life of your engine, without over cooling in low temperatures.

  • Engine Oil Cooler for a 2007 Chevy Silverado New Body Style with 6.0 Liter Motor
    Since the Derale Combination Transmission and Engine Oil Cooler # D15902 is both a transmission and oil cooler it would need to take the place of the cooler that you have. However this will likely provide less transmission fluid cooling than your existing external cooler. What I recommend for your 2007 Silverado (New Body) with 6.0 liter motor is to just add a small oil cooler only so that you will get the maximum benefit of both coolers. I recommend Derale Tube-Fin Engine Oil Cooler Kit...

  • Can an Oil Cooler and Filter Relocation Kit be Used Together
    Yes, you can use the Derale Oil Filter Relocation Kit # D15748 with an oil cooler. The cooler should be placed so that the oil goes through the cooler last. The addition of an oil cooler and the hoses for it will increase the amount of oil you will need so be sure to check the oil after installation and add however much is needed. You could use kit # D15551 which is a cooler and it has the relocation parts all in one kit. We installed this set up on a co-worker's truck. I have linked the...

    There are three basic types of heat exchangers. Tube and fin, plate and fin and stacked plate. Stacked plate being the most efficient.

The cooler I recommend is the Derale stacked plate oil cooler kit with Sandwich adapter # D15602 because it's super efficient and one of our most popular ones we currently offer. It will reduce oil temps by as much as 50 degrees. The external lines via the sandwich adapter makes installation...

  • How to Install a Derale Engine Oil Cooler, Part # D15505, in a 1970 to 1974 Hotrod
    Engine oil coolers are not brand- or model-specific; you can install an oil cooler as large as the space you have available to mount one, which is generally in front of the radiator and/or air-conditioning condenser on vehicles so equipped. With coolers, larger is better. This particular kit is intended for vehicles with an engine block oil filter landing between 2-3/4 inches and 3-1/2 inches. If your vehicle oil filter landing falls outside this range you will need to select an alternate...

    It sounds like it could be a transmission cooler. What you can do is when the vehicle is cold, start it up and place it in drive for about 10 seconds or so. Then return it to park and turn off the motor. Feel the hoses and if one is noticeably cooler than the other then it is a transmission cooler. Coolers are normally found inside of the radiator. It is possible that someone has installed a supplemental one on the vehicle if there were other owners before you. If it looks like # D13260...

This pan as you referenced is 6-1/8" tall from the top flange to the bottom base.
