Step3- Now it is for 2 to 3 minutes. Till the coolant becomes stable and stops moving. Now start the engine of your vehicle.

Step4- Now to receive a response to the bleeding. Turn your vehicle heat to high and the fan to low. This will allow all the air bubbles to move upward. Keep this way for more than 10 minutes. The coolant will fill the radiator and all the air will remove by popping all the bubbles out.

Step5- Now keep an eye on the coolant level. If the air will remove then the coolant level will decrease as the coolant will fill in the engine. So make sure you keep an eye on before and after levels. This will give you an idea of how much air has been bleeding out from the vehicle.

Step6- Now when the coolant level stops dropping you should check the engine temperature. By checking the normal engine range you will make sure that the air bleeding has been done properly.
