Be careful pressurizing your cooling/heating system for long periods of time. The 1948 system was designed for 0psi (maybe up to 4psi in large trucks).

Good find on the hose. Remember that the coolant level should hold steady at about 2 inches under the filler cap.

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.
