You can remove the coolant surge tank pressure cap
when the cooling system,-including the coolant surge
tank pressure cap and upper radiator hose, is
no
longer hot. Turn the pressure cap slowly about
one-quarter
turn
to the left and then stop.
If
you hear
a
hiss,
wait for that to stop.
A
hiss
means
there is still some pressure left.

Then keep turning the pressure cap slowly, and
remove it.
