Re: Pressurized cooling system on a 1939 120

1. Not sure, but 1941 was pressurized, 4 lb for non AC cars.
2. Perhaps, but to what gain? The car was engineered with plenty of cooling capacity with its original system so if you have the system in good condition, you shouldn't have a problem sitting in traffic. Many of us with older Packards crawl along in July 4th parades on 95 F. days and do just fine without a pressure system or overflow tank.
3. No benefit apparent to me.
