You have a thermosyphan coolant system. This simply means that there is no thermostat or water pump. The coolant circulates by the engine getting the water inside the bolck hot enough that it rises upward to the top of radiator and at the same time pulls the cooler coolant in the engine from the lower radiator. This creates a downward circulation through the radiator where the coolant is cooled. Coolant expandes when it is heated, therefore if you filled radiator brim full then the expansion is going to cause some overflow. These systems are ussually not pressurized, so an inche or two of air at the top of radiator is normal to allow for expansion, but note that the level of coolant must be above radiator cores and the top radiator hose for the system to work. I would fill the radiator brim full and ignore a little overflow and keep it at that level as long as you can look in the top and see the coolant level isn't below where the system won't fuction. The coolant level should be brim full with the engine completely warmed up but will be lower than that when cold. I would pretty much bet, that is your problem. But if it is by chance overheating, coolant will continue to come out overflow when engine is completely warmed up and the engine will get hotter than normal and the more hotter it gets the more coolant will come out (it will likely steam or boil over). In this case, a clogged up radiator will likely be the problem. I would likely guess that you are experiencing normal overflow from filling radiator brim full when cold rather than overheating. You will just have to check it out.

Today's Featured Article -
New Life for an Old Allis - by Tyler Woods. My friend Jon, has an old '39 Allis Chalmers B. He thought it a marginal tractor that had long since served its time.

Jon's Allis has a small front loader and though it doesn't carry much, it serves his needs. It was the hard starting and low power that made him think it was time to replace the old girl. Jon called me to help him discover why his tractor wouldn't start
