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
counterclockwise (left) about two

you hear a hiss, wait
for
that
to
stop. This will allow any pressure
still
left
to
be vented out the discharge hose.

Then keep turning the
pressure
