How to Bleed Air When Replacing Coolant in a Porsche?

[StRhett]

To bleed air when replacing coolant in a Porsche, follow these steps: 1. Run the engine until the coolant temperature reaches 90°C, then turn off the engine. 2. Let the engine cool down to room temperature. 3. Pull the hood release lever. 4. Lift the hood upwards. 5. Slowly unscrew the cap of the coolant expansion tank to release high-pressure air from the system. 6. Disconnect the radiator return hose to drain the coolant, then reconnect it. 7. Fill the expansion tank with coolant to the maximum level. 8. Repeat the process twice to ensure all air is purged from the cooling system. Taking the 2020 Porsche 911 as an example, it is a 2-door, 4-seater hardtop sports car with dimensions of 4519mm in length, 1852mm in width, and 1298mm in height, a wheelbase of 2450mm, and a fuel tank capacity of 64 liters.
