In a discussion about old flat head Fords, the question came up as to when Ford first pressurized the cooling system? I think 1936 was the first year to have the radiator cap under the hood, but when did presurized caps begin? 1934 Ford's since 1972

1946...See > https://www.themotorhood.com/themotorhood/2015/9/22/the-history-of-fords-iconic-flathead-engine 1946 - Fords get Mercury’s larger flathead. It has new pressurized cooling, revised aluminum pistons, and silver alloy bearings for longer life. The rod journal size is increased. To reduce cracking, the angle between the valves (passenger’s side to driver’s side) is decreased from 101.5 degrees to 100 degrees. The fan is moved up to just above the distributor to spray less water over the engine in wet weather. The distributor gets a new one piece cap, eliminating the old two piece system. http://myflatheadford.com/spec-history-ford-flathead-v8-1932-1953/ This message was edited by MG on 2-10-20 @ 8:05 PM

My '46 Coupe has a pressure cap. The 1941-48 book, on page 5-19, lists the cap as P/N 41A-8100 with a 3.5 to 4.5 psi rating.
