How do you get the air out of the engine after changing the thermostat on a Saturn sl2?

Don't worry about it. If the engine has not been damaged, all you need to do is keep the coolant reservoir full, and run the engine enough to get it hot at which point it will push out a lot of the air. After it cools again, it will pull in the coolant.
Keep the coolant level up by checking it every time you get ready to go somewhere. You'll notice when the coolant level no longer drops.
Note that if the engine has overheated, it could have been damaged. If that happened, there could be a failed head gasket or cracked head. When either of those happen, combustion gas is forced into the coolant space, forcing coolant out of the engine and causing the engine to overheat rapidly. Unfortunately, if that has happened, the only option is to replace the faulty parts and re-surface the head.

Why does a 1999 Saturn heats up to half way on temperature gauge then cools off to quarter when parked idling?
The 1999 Saturn S-Series engine heats up the coolant, the thermostat valve opens and the coolant circulates between the radiator and the engine. Then the radiator fans turn on to cool it back down. The fans are also turned on when the air conditioner is turned on to aid in cooling the radiator and the air conditioner condensor.
