I thought I'd ask this one with a wide audience. I have an R12 plastic expansion tank in the R8, with its orginal BLACK cap. My spare cap is GREEN, like our Citroen CX. They are Bailly Comte brand from Lyon. These tanks came in various cars with various pressure ratings. My spare (green) seems to be rated at 1 bar. I don't know what pressure rating applies to the black one. They came in blue as well, and similar later caps came in white on black and black on white.
Does anyone know what pressure ratings apply to the different caps? I've not had much luck looking on line. I want to replace the very old cap on the R8 but am not sure what pressure to use or, indeed, whether it really matters.
All comments most welcome! Thanks in advance.
