Radiator cap question

[IROCKWITHDIRT]

All the radiator caps I see for 9n's are for a conventional neck like you would expect to see on a car. What've I got going on here?

Thanks for any help!

Rocky....it appears you have the original 9n radiator and it will require the 9n8100 cap.If not available here,you can get it at nnalert. don b 1

Rocky.......the original coffin-tank 9N radiator were UNPRESSURIZED and require a different cap than the 4-psi pressurized radiators later N's used. Modern Belchfire-V8 use 14-psi radiator. (higher pressure, more heat capacity before boiling) ......Dell

It looks like You are missing the radiator pad that goes between the radiator and hood.---lha
