core plugs / freeze plugs

[Nick Challacombe]

The reason that it has a 15lb radiator cap is that is what Bristol Cars
recommend,
It is what is in the handbook and workshop manual, it is what Brian Marelli
keeps
in stock for them.
As there is no correlation between the engines or cooling systems on the
cars I expect the workshop
manual on the 411 shows a 13lb cap on that car/engine set up.
I do not pretend to know about 411's only 407,408 engines and cars.

I would never presume to pull up the fountain of all knowledge on 411's but
I do have a workshop
manual for a 407, I would never dream of disputing you on a 411 so why
question me and a 407/8.
