Radiator Cap

[Bob G]

I have a 1987 Avanti.  I need to replace the radiator cap.  Does anyone know what max. PSI the cap should hold?  I have been told 7 PSI by one parts dealer and 14 PSI by another.

Thanks,

Bob

Thanks.  I actually opened the owner's manual and it also states RC27, AC Delco

Real men don't need no stinking owners manuals.

Good luck,
