Engineered for Harley-Davidson Touring models from 1984 to 2016 (including 2014-2016 Twin Cooled motors), Softails from 1985 to 2017, and Dynas from 1990 onward, this ULTRACOOL side mount oil cooler is designed for 1 1/4" or 1 1/8" frames. The system utilizes a specially designed dual pass aluminum heat exchanger featuring turbulators to maximize heat dissipation, aiming to maintain optimal oil temperatures between 200 and 230 degrees. A thermal switch with waterproof connectors automatically activates the cooling system when oil reaches 210 degrees, keeping the fans engaged until the temperature drops to 185 degrees.
The unit features sealed waterproof IP68 dual fans that generate 220 CFM of airflow, paired with black nylon coated stainless steel braided oil lines and AN6 fittings. Installation is simplified by a plug-and-play wiring harness with a relay and waterproof connectors that link directly to the battery under the seat. An L.E.D. indicator light on a black perch mount provides visual confirmation of fan operation, while the kit includes a special oil line fitting wrench and detailed instructions for a straightforward setup.
