BT 5088 – Aluminum Komatsu D39-PX21 Dozer Oil Cooler

The BT 31202632 all aluminum, heavy duty oil cooler is an exact fit, OEM replacement for Komatsu D39-PX21 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 30.50 inches from tank to tank, 19.84 inches from side to side, and 2.625 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.
