Engine Overheating - Chevrolet Captiva Owner's Manual

3. Fill the coolant surge tank with the
proper coolant between the MIN
and MAX lines.
4. With the coolant surge tank pressure
cap off, start the engine and let it run
until the upper radiator hose can be
felt 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, add more
of the proper coolant to the coolant
surge tank until the level reaches
between the MIN and MAX lines.
5. Then replace the pressure cap. Be
sure the pressure cap is hand-tight.
Check the level in the surge tank when
the cooling system has cooled down. If
the coolant is not at the proper level,
repeat Steps 1 to 3 and reinstall the
pressure cap. If the coolant still is not at
the proper level when the system cools
down again, see the CHEVROLET
retailer.
