As Jack's answer implies, the presence of a water pump is often a symptom of a poor cooling system. There are two likely reasons. One is that the radiator and all the passages need a good cleaning out. The other is that the radiator is shot. Start with the cleaning. Here are some videos:

If the vehicle overheats after a thorough cleaning, it's time to spend some dough. After ninety years of vibration the cooling fins have come loose from the tubes in many of these old radiators. Both solutions to that cost money. One is to have a good radiator shop install a new core. The other is to buy a new radiator. I recently had a 1915 radiator recored because that was $200 less expensive than buying a new one, and because I like the original tank better than the new ones.
