: I recently saw a posting discussing that a 5 psi pressurized was used. This sounds like a good idea to me. If my old physics is still good, it should add 5 C temperature protection from boiling.to 221 F.My question, is how is this done, is there a limit on how much pressure would work and how do you maintain the pressure (type of cap, etc.)
Tony, my opinion on pressurizing the cooling system; Why. If the cooling system in your car is restored to original condition andthe car is driven as Henry intended there is no need for pressurization. I reconditioned the radiator and verified flow rate of 30 gal per minute min. Rebuilt the water pump repairing the block to minimize end play and run distilled water with soluble oil and drive almost daily in Phoenix, Arizona with no problems. Climbing the infamous Yarnell Hill north of Phoenix poses NO problems. I never add water between flushings and I flush (read drain, flush with garden hose and replace) every 6 months. My only accomodation to modern tech is a plastic fan. Keep it original and keep it clean and it won't overheat.
