How to bleed air from the cooling system?
To bleed the cooling system: Fill the expansion bottle with a mixture of coolant and water. Keep the cap off. Turn on your car and let it idle. Squeeze the top radiator hose until no more bubbles appear in the expansion bottle. It’s better to do this when the car is warm and the thermostat is open, thus allowing the water to circulate.
