Re: 51 300 Radiator Cap?

There may be a couple of misprints -- or changes with the cap pressure.. Originally 51 - 52 were 7 psi but in SC Vol27#2 they introduced a 12 psi pressure cap for the 26th series senior models. Said it was also available as a service part for 24 and 25 series cars and they didn't appear to restrict it to any particular models. The specs for 53 seniors and all 54 except 1 chassis says 12psi. Parts book doesn't mention that 12psi cap but has another part # listed as a 13 psi for all 51-4.
