Why Is Lower Radiator Hose Larger?
In the design of a tractor cooling system, seemingly small details like the size of bulk radiator hose plays a significant role in the overall efficiency and performance of the engine. Kubota tractors, like many other heavy machinery, often feature a noticeable difference in the size of the upper and lower radiator hoses. Specifically, the lower radiator hose tends to be larger than the upper one. This difference in size may appear puzzling at first glance, but it serves several critical purposes in maintaining the optimal function of the tractor’s engine.
