For easier cleaning and servicing, the trucks feature a modular radiator design that provides more space than previous models. The new design features a single-pass flow system, which is said to cool more efficiently than the dual-pass system previously offered. Caterpillar says the trucks have 100-percent more glass area for improved visibility.
