A pressurized coolant reservoir would have a thread on cap which acts as the " rad " cap
ALSO, Keep in mind that your coolant system is designed to be pressurized. When it is under pressure the coolant can work very efficiently to keep your engine at operating temp. If you have a small leak, even a pinhole (or head gasket leak etc.) your engine will easyily overheat because the "boiling temperature" of the coolant is significantly decreased when its not pressurized. For example when the coolant is pressurized it can withstand about 270 degrees, but when not pressurized it can maybe withstand 230 degrees.
A surge tank is basically a pressurized coolant reservoir. As your engine heats and cools the coolant expands and contracts. Because of this You need a place for extra coolant to go to when it expands and be drawn from when it contracts. Conventionally the recovery tank or reservoir was not pressurized. A tube from the radiator cap allowed coolant to be sucked and drained in to the reservoir. However, on many newer vehicles like yours the reservoir is pressurized and called a surge tank.
Pressurised coolant boils at a higher temperature than unpressurised

location of 2003 cadillac coolant temperature sensor
The coolant used in a pressurized water reactor is typically purified water. This water is pressurized to prevent it from boiling and is circulated through the reactor core to remove heat generated during the nuclear reaction.
where is the coolant temperature sensor located in a 1999 cadillac seville sls?
Yes; it's on the coolant reservoir. The entire coolant reservoir on the Saturns is pressurized.
