4.
With the coolant surge
tank pressure cap
off,
start the engine and let it
run until you can feel
the upper radiator hose
getting hot. Watch out
for
the engine cooling fan.
By this time, the coolant level inside the coolant
surge tank
may be lower. If the level
is
lower than
the FULL COLD mark, add more of the proper
mixture to the coolant surge tank until the
level reaches the FULL COLD mark.
5.
Then replace
the
pressure cap.
Be
sure
the
pressure
cap
is
hand-tight and
fully
seated. See
your
dealer,
if
necessary.
