Abstract
An apparatus and method for cooling a work machine is disclosed. The apparatus has a fan element located inside an engine compartment of the work machine in a horizontal orientation. The fan element draws external air from above the work machine into the engine compartment. A deflector directs the air through a plurality of cooling cores which are radially spaced about the engine compartment and interspersed with a plurality of core spaces. The apparatus can be cleaned by spraying fluid from the outside through the plurality of cooling cores, causing any trapped debris to fall to the bottom of the engine compartment, where it can be removed through a cleanout.
