The new cube-shaped cooling system on the 621D wheel loader from Case provides premium performance in extreme conditions while the loader itself delivers 133 net hp from the fuel-efficient Case 6BT-590 turbocharged engine. The D Series cooling system uses a Case-exclusive mid-mount, cube-shaped module that supplies the cleanest air and more efficiently cools the engine and components. By eliminating stacked coolers, the cooling system design prevents debris from plugging between coolers. This reduces owning and operating costs through less fluid breakdown and lower component wear. www..com
