The subject of special water pump lubricants for the Model A, Model B and 1932 V8 engines is covered by Ford Service Bulletins for Sept-Oct 1932.

It is covered in more detail but I will quote a rather long sentence:

" The water pumps (both 4 cylinder and V8) were designed to use pressure gun lubricants which melt at temperatures below the temperatures reached by the water in the cooling system, and offer little resistance to the flow of the water should any find its way into the cooling system, whereas many of these special water pump lubricants have a melting point considerably higher than the maximum water temperature which permits such surplus, as is forced into the cooling system, to lodge in the radiator tubes and effectively blocking them.""
