Radiator cap pressure.

Looking for the proper lbs. pressure cap for my 49 Commodore 8. 
Thanks in advance.

According to parts book pressure caps were not used until 1950.

My 49 has a pressure cap of 7 lbs. maybe it has a 50 radiator I don't know for sure. 7 lbs seems high to me. Should I be concerned?

You need to confirm the year of the radiator as pressure caps can indeed put undue stress on earlier built radiators and internal cabin heater coils

Let assume it's a 1950, is 7 lbs. ok?

7 lbs is fine for radiators from the 1950s. Any more than that, might tend to damage the radiator, just because the tank is so large.

Thanks for the info.
