How do you bleed the cooling system on a 2001 Volvo S60?

To bleed the cooling system on a 2001 Volvo S60, start by ensuring the engine is cool and the radiator cap is removed. Fill the coolant reservoir to the proper level and then run the engine with the heater set to maximum until it reaches operating temperature, allowing the thermostat to open. As the engine runs, keep an eye on the coolant level, adding more if necessary, and squeeze the upper radiator hose to help release any trapped air. Once the air is purged and the coolant level stabilizes, replace the radiator cap securely.
