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 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.

  • Oil Cooler for 1.9L Volkswagen Diesel Engine
    Diesel engines in general operate at higher temperatures than gasoline engines. Gas engines have a typical oil temp of 200 - 250 degrees F, while diesel engine temps can reach as much as 600 degrees (!) within the cylinders. Your 1.9L Volkswagen diesel can be fitted with an oil cooler, according to my contact at Derale, as long as its oil pump is in good shape. Oil coolers are not vehicle-specific, nor fluid-specific; you can use as large and efficient a cooler as you have space to install...

  • Could Derale Engine Oil Cooler D15001 Fit 2005 Nissan Xterra to Replace Factory Cooler
    Our oil coolers install between the oil filter and the vehicle block like the part # D15501 that you referenced. This would perform the same function as your factory cooler and since it comes with a thread adapter that fits the oil filter of your 2005 Nissan Xterra it also is a confirmed fit so this would be a solution.

  • How to Install Derale Tube-Fin Engine Oil Cooler # D15501 in 2001 Jeep Cherokee
    Coolers like the Derale Tube-Fin Engine Oil Cooler # D15501 are not vehicle-specific so you can install as large an oil cooler as you have room to mount it. This unit measures 12-3/4 wide x 7-5/8 tall x 3/4 deep and ideally mounts in front of your AC condenser for maximum air flow and cooling. This kit includes a sandwich adapter that mounts in place of your existing oil filter and that provides a range of threaded inserts, one of which will match your filter size. Your filter will then...

  • Will the Derale Tube-Fin Engine Oil Cooler Kit # D15501 Fit a 2014 Ford Flex SE 3.5L V6
    The Derale Tube-Fin Engine Oil Cooler Kit # D15501 comes with multiple thread sizes for the sandwich adapter. It looks like your 2014 Ford Flex SE with the 3.5L V6 engine has a 22 mm x 1.5 mm thread size which means you need to use the connector with the green mark on it. I have linked the installation details for you to reference as well.

  • Transmission, Engine Oil, and Power Steering Cooler Recommendations for a 2006 Honda Odyssey
    If the vehicle manufacturer recommends a transmission cooler, power steering cooler, and/or oil cooler, it is best to follow their recommendation. Even when towing light loads, there will be extra stresses on the vehicles components and it is better to be safe than sorry. For a transmission cooler, a small one will work fine for your application. You can use # D12901. I have included a link to our FAQ article on transmission coolers for you to view.

  • Transmission Cooler and Engine Oil Cooler Recommendations for a 2008 Chevy Express Van, 4.8 Liter V8
    Transmission coolers are not vehicle specific, but there are ones that are recommended for certain engine sizes. What I did was look up the recommended coolers for the 4.8 liter engine for the 2008 Silverado to get an idea of what we recommend for that engine size. The most popular cooler for the 4.8 is the Derale Transmission Cooler, # D13502, and GM fitting, # D13035. The cooler is listed for a load of up to 3,500 pounds. Before deciding on a cooler though it will be a good idea to...

    You can use a transmission cooler like an engine oil cooler, however, to make it work properly there are adapters and modifications that will be required.

When picking out an engine oil cooler the guideline is to pick a cooler that can accommodate the same engine oil filter thread....

  • Engine Oil Cooler for a 1997 Chevy Pickup Truck with 5.7 Liter Motor
    In 1997 Chevy and GMC trucks were just called either a C series or K series. Silverado was only a trim level at that time. The trucks weren't called just Silverados until 1999/2000. But oil coolers and sandwich adapters are not fit guided anyway. You can add an oil cooler to your 1997 Chevy pickup but you would not use the cooler portion of the radiator since it was designed for use with the transmission fluid. What I recommend is a kit, # D15501, so that the oil has its own cooler....
