1. 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.
Remove the coolant surge tank pressure
cap by slowly turning the pressure cap
counterclockwise about one full turn. If you
hear a hiss, wait for that to stop. A hiss means
there is still some pressure left.
2. Then keep turning the pressure cap slowly,
and remove it.
3. Fill the coolant surge tank with the proper
mixture, to the FULL COLD mark.
