How do you bleed the cooliong system?

To bleed the cooling system, start by ensuring the engine is cool and the radiator cap is removed. Fill the radiator with coolant until it's full, then run the engine with the heater on high. As the engine heats up, air bubbles will escape; keep an eye on the coolant level and add more if necessary. Once no more bubbles appear and the coolant level stabilizes, replace the radiator cap securely.
