Why is my 1972 Case 450 dozer running hot?

My 1972 Case 450 dozer starts running hot while pushing dirt. The temperature climbs to around 220F and begins pushing coolant out, even after replacing the radiator cap. The thermostat has been removed, and the radiator is clean. I also noticed the fan pushes air through the radiator toward the blade-is that normal for this model? Any ideas on what else I should check?
