If this is for an S-Series, you don't have to, The system has a deairiation line and does it on its own.
To burp the cooling system on a 2002 Saturn, start by ensuring the coolant reservoir is filled to the proper level. Next, with the engine cold, remove the radiator cap and start the engine, allowing it to reach operating temperature. As the thermostat opens, check for air bubbles escaping from the radiator; add coolant as needed. Finally, replace the radiator cap once the bubbles stop and the coolant level stabilizes.
You need to burp the radiator and cooling system.
It should have a bleeder screw on top of the thermostat housing.

If you don't burp your engine, air bubbles can remain trapped in the cooling system, which can lead to overheating and inefficient engine performance. These air pockets can prevent proper coolant circulation, potentially causing engine damage over time. Additionally, neglecting to burp the engine can result in fluctuating temperature readings and reduced effectiveness of the cooling system. Regular maintenance, including burping, helps ensure optimal engine operation.
Locate the plug on the bottom of the radiator to drain it. Put some radiator cleaner in and drain it again.
The air bleeder plugs on a 2002 Saturn cooling system are typically located near the highest points of the system, such as near the radiator or on the engine block. They are used to release any air trapped in the system to ensure proper coolant circulation. Consult your vehicle's manual for specific locations.
You carefully remove the top coolant hose to the heater, not totally off, just enough so air can get out.
Remove coolant cap, allow engine to get to operating temperature, turn on heater full blast and patiently wait for air to escape system.
