A cooling system mounting arrangement includes a platform of an article of construction machinery and an engine enclosure and a cab and cab riser mounted to the platform. The engine enclosure includes an engine and associated engine cooling system. The cab is mounted atop the cab riser, and the cab riser is adapted for ducting cooling air to an auxiliary cooling system disposed in the cab riser separate from the engine cooling system. The auxiliary cooling system includes a heat exchanger and a fan assembly for flowing cooling air across the heat exchanger. The fan assembly is movably mounted to the cab riser for movement between a first position adjacent to the heat exchanger for flowing cooling air across the heat exchanger and a second position spaced apart from the heat exchanger to permit access to the downstream side of the heat exchanger for cleaning and maintenance. An inlet screen is mounted to an inlet of the cab riser and is similarly movable between a first position adjacent to the heat exchanger and a second position spaced apart from the heat exchanger to permit access to the upstream side of the heat exchanger for cleaning and maintenance.
