BT 5059 – Komatsu WA700-3L Oil Cooler


The BT 5059 all aluminum, heavy duty oil cooler is an exact fit, OEM replacement for a Komatsu WA700-3L. 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 57.25 inches from tank to tank, 58.625 inches from side to side, and, 3.150 inches thick. Thick wall, U-channel tanks are TIG welded to the core to ensure the strongest possible bond and has an 1 inch inlet and outlet. Each unit is individually tested prior to shipping and guaranteed to be 100% leak free.
