How do you remove air lock on Skoda fabia?

To remove an air lock in a Skoda Fabia, start by ensuring the vehicle is on a level surface and the engine is cool. Open the radiator cap and fill the cooling system with the appropriate coolant. Then, start the engine and allow it to reach operating temperature with the heater set to maximum. This will help circulate the coolant and push out any trapped air; keep an eye on the coolant level and top off as necessary until no more bubbles escape.
