psi
above
atmospheric
pressure
The
relief
valve
consisting
of
a
blow
off
valve
and
a
vacuum
valve
helps
to
prevent
the
coolant
from
boiling
by
giving
pressure
to
it
How
ever
when
the
pressure
is
reduced
below
atmospheric
pressure
the
vacu
wn
valve
allows
air
to
re
enter
the
radiator
preventing

up
to
an
extent
the
pressure
relief
valve
provided
in
the

opens
to
release

provid
ed
in
