BT 5186 – Aluminum Komatsu Oil Cooler

The BT 5186 all aluminum, heavy duty oil cooler is an exact fit, OEM replacement for Komatsu D51EX-22 Crawler Dozers and Komatsu D51PX-22 Crawler Dozers. Manufactured in the USA using controlled atmosphere brazing, the epoxy-free core is built using our most durable heat exchanger design that is capable of withstanding tremendous heat and pressure. Solid, extruded tubes are brazed together as one unit without the use of header plates, thereby eliminating thousands of potential failure points. The core measures 35.25 inches from tank to tank, 8.875 inches from side to side, and 5.50 inches thick. Thick wall, U-channel tanks are TIG welded to the core to ensure the strongest possible bond. Each unit is individually tested prior to shipping and guaranteed to be 100% leak free.
