Hi all,

Please which v8 Rad Cap should we choose for 440 or 383, maybe does it make a difference

CT6119 - 15lbs Rad Radiator Cap
CT5048 - 13lbs Rad Radiator Cap

It would be good to know - The radiator cap is a non-blowoff. This cap is just for the expansion tank

Thank you
Neil

Mk1 Owners handbook says 13psi
Mk2 Owners handbook says 16psi
Don't know for Mk3.

By the hand book the expansion cap for a mk 3 440 is 13lb not sure if this answers your question ?

MK3 handbook - 1972 - 440 H series

Page 24 - Cooling System

The cooling system is pressurised to 13 psi and therefore operates at a higher temperature than normal.

I wonder the reason for the 16lbs for the mk2 and the 383

cheers
Neil
