How to Add Coolant to the Coolant Recovery Tank
If you haven't found a problem yet, but the coolant level isn't at or above the
ADD mark,
add a 50hO mixture of clean water (preferably distilled) and a
proper antifreeze at the coolant recovery tank. (See "Engine Coolant" in the
Index for more information about the proper coolant mix.)
When the coolant in the coolant recovery tank is
at or above the ADD mark,
start your vehicle.
I f the overheat warning continues, there's one more thing you can try. You
can add the proper coolant mix directly to the radiator, but be sure the
cooling system is
cool
before you do
it.
A
Steam and scalding liquids
from
a hot coofing system can blow out
and burn you badly. They are under pressure, and if you turn the
radiator pressure cap-even a little-they can come aut at high
speed.
Never
turn the
pressure
cap
when
the cooling
system,
including
the
radiator pressure cap, is hot. Wait for the cooling
system and
radiator
pressure
cap
to
cool
i f you
ever have
to turn
the pressure cap.
