The CAT 84909G radiator is engineered specifically for the CAT TEREX MT5500 Rock Truck to tackle common cooling system failures under heavy-duty mining conditions. It features a multi-braced header design and seam-welded mounting points to prevent cracking at high-stress zones typical in large-frame rock trucks. The staggered louvered fins are treated with an anti-dust coating to reduce debris buildup and maintain airflow without frequent cleaning. Vibration-resistant tube bundles with interlocked construction minimize fatigue failure caused by constant impact and shifting loads. This radiator delivers targeted protection in extreme environments, directly addressing the MT5500’s vulnerability to frame flex, dust clogging, and vibration-induced leaks—effectively extending service life and reducing unplanned downtime.
Features
High-efficiency copper tube and fin core for improved heat transfer.
