Stacked-plate heat exchangers have long been considered the most effective type of oil or transmission cooler, primarily because of their increased surface area. Allowing fluid to spread out over this larger surface area decreases the time required for heat transfer to take place. As a result, plate coolers typically manage to cool a greater volume of fluid faster than tube-and-fin, or even plate-and-fin, varieties. Add to that the turbulator technology - whereby fluids are agitated continuously to not only facilitate heat transfer, but also to prevent any undesirable drop in pressure - and you have an absolutely superior cooling system.

  • Comparing a Remote Mount and Standard Transmission Cooler
    The Derale Hyper-Cool Remote Transmission Cooler Kit w/ Fan part # D13960 would absolutely provide greater cooler power than the Derale 25-Row High-Performance Stacked-Plate Cooler part # D52508.

If you find yourself in a lot of stop and go traffic then the cooler with a fan would...

  • Supplemental Transmission Cooler Recommendation for a 2008 Cadillac Escalade
    Actually for best results you would want to keep your factory transmission cooler and then add a supplemental one like the part # D52508 that you referenced. You would also need two of the barb fittings part # D98202 and then hose like part # D15700 and hose clamps # D13008 as well. You will want to route the cooler downstream of the factory cooler so that it first goes through it and then through the Derale. Your fluid temps are crazy high right now, but with an efficient cooler like...

  • Suggestions For Dealing With Overheating Motorhome
    Although it is always a great idea to add supplemental coolers to help improve overall engine performance, from the information you have provided, I think the issue may be something other than the transmission being overworked, I would have an auto service check out the vehicle to eliminate other potential causes for the overheating problem. After any issues are taken care of and it is running properly, we do offer some cooler options for you. Before considering a cooler for your 2005...

  • Recommended Transmission Cooler for a 2013 Chevy Tahoe
    I have the perfect transmission cooler option for you. Generally speaking, the best transmission cooler to use would be the largest one you have available space for. The best place to install a transmission cooler is in front of the radiator/condenser behind the grill on your 2013 Chevy Tahoe. I recommend using the Derale 25-Row, High-Performance, Stacked-Plate Cooler part # D52508 because the plate and fin technology incorporated into this transmission cooler is far more efficient than...

  • Fittings and Other Parts Needed to Install Transmission Cooler D52508 in a 2010 Chevy Tahoe
    Derale Snap-In Radiator Adapter Fitting # D13035 is recommended when installing a transmission cooler on the 2010 Chevy Tahoe. I have linked a video featuring this fitting for you. In addition to the fitting and the core, # D52508, you will also need a bracket kit # D50020 to mount the cooler, hose clamps, # D13008, and about 10 feet of hose, # D15700. We also have a 25 foot length of hose, # D15799, if you want to err on the side of caution; especially if you are also installing a bypass...
