A damaged expansion tank can lead to coolant loss and potential overheating. During inspection, an expansion tank may show cracks or stress marks from thermal cycling. The tank's condition directly affects the cooling system's ability to maintain proper pressure. Keeping an expansion tank in sound condition helps prevent air from entering the coolant circuit. This aftermarket replacement part references the Bobcat catalog and carries the part number BC78688.9. The tank serves as a reservoir for excess coolant as it expands when heated.
