How To Add Coolant To The Coolant Surge Tank - Chevrolet 2011 Cruze Owner's Manual

The coolant surge tank is located
in the engine compartment on the
driver side of the vehicle. See
for more information on
location.
If no problem is found, check to
see if coolant is visible in the
coolant surge tank. If coolant is
visible but the coolant level is not
at the indicated level mark, add a
50/50 mixture of clean, drinkable
water and DEX-COOL coolant at
the coolant surge tank, but be sure
the cooling system, including the
coolant surge tank pressure cap, is
cool before you do it.
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. They are
under pressure, and if you turn
the coolant surge tank pressure
cap even a little they can
come out at high speed. Never
turn the cap when the cooling
system, including the coolant
surge tank pressure cap, is hot.
Wait for the cooling system and
coolant surge tank pressure cap
to cool if you ever have to turn
the pressure cap.
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water
and other liquids, can boil before
the proper coolant mixture will.
The coolant warning system is
set for the proper coolant mixture.
With plain water or the wrong
mixture, the engine could get
too hot but you would not get the
overheat warning. The engine
could catch fire and you or
others could be burned. Use a
50/50 mixture of clean, drinkable
water and DEX-COOL coolant.
