11" Wide x 3-7/8" tall x 1-1/4" deep, radiator-style heat exchanger improves the performance and overall functioning of your vehicle's transmission. Includes hose-barb adapters to fit the 1/2" NPT inlets.
Features:
Specs:
Note: The Derale Insta-dapt radiator adapter fits most vehicles with 5/16" transmission lines, but not all. In some cases, additional fittings or alteration of the OEM lines or hoses may be required for installation.
One of the more popular cooling systems available, the radiator-style, plate-and-fin heat exchanger provides increased surface area so that fluids can spread out along the finned chambers to cool faster. In addition to the increased surface area, this cooler also features turbulator technology, whereby fluids are agitated continuously, not only to facilitate heat transfer, but also to prevent any undesirable drop in pressure.
