To bleed air from the cooling system on a Cadillac STS, first ensure the engine is cool, then locate the bleed valve, usually found near the thermostat housing or on the radiator. Start the engine and allow it to reach operating temperature, then open the bleed valve slowly until coolant flows out without bubbles. Close the valve, check the coolant level in the reservoir, and add more if necessary. Finally, run the engine for a few minutes to ensure the system is free of air and monitor the temperature gauge.
