Chevrolet STFF6S Automobile User Manual


 
The coolant level
should be
at
or above
the
COLD
mark.
If
it
isn’t, you may have a
leak in the radiator
hoses, heater hoses,
radiator, water pump
or somewhere else in
the cooling system.
NOTICE:
Engine damage from running your engine without coolant isn’t
covered
by
your warranty.
If
there seems to be no leak, start the engine again. See
if
the fan speed
increases when idle speed
is
doubled by pushing the accelerator pedal down.
If it doesn’t, your vehicle needs service. Turn
off
the
engine.
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
COLD
mark, add a
50/50
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.)
