Saturn 2008 Aura - Manual (Page 281)

Cooling System
When you decide it is safe to lift the hood, this is what
you see:
A. Engine Cooling Fans
B. Engine Coolant Surge Tank
C. Pressure Cap
{ CAUTION:
An electric engine cooling fan under the hood
can start up even when the engine is not
running and can cause injury. Keep hands,
clothing, and tools away from any underhood
electric fan.
If the coolant inside the coolant surge tank is boiling,
do not do anything else until it cools down. The vehicle
should be parked on a level surface.
