Re: 1938 Super 8 coolant leak

I rather doubt that the leak, if at the shaft packing, will "seal itself". The packing nut is a normal hex-head but access with a regular wrench is difficult if not impossible; there was a special which you can still buy (Byron York has them), or you cold get a stock "Martin pump wrench" in the correct size from MSC, perhaps McMaster. I'll post if I already have a picture.
I'm rethinking my comment that the two ball bearings were open bearings with seals, but you'll find out. If you buy the original split-ring packing you should be able to do it with the pump on the car, but removing the pump is so simple I wouldn't bother - but your choice. I'll enclose a scan of the 37 Super 8 pump, 38 is the same except it has larger bearings and a lightly different body, shaft and impellor.
