How to Bleed Air from Your Cooling System
To bleed air from a air cooling system means to release air pockets that are trapped in cooling systems such as radiators. These air pockets that form inside your radiator can cause overheating simply because you will assume that your radiator’s coolant reservoir seams full but in fact it is just air that is regulating around it. Since 70 percent of gasoline in your car is converted into energy, heat is also produced and it is the car’s cooling system to keep everything balanced. Too much heat and less air cooling in the engine can cause overheating problems and can kill the engine. The car’s cooling system’s job it to take this heat and convert it into air. And since an engine also requires the right amount of heat, the cooling systems will allow the engine to heat up as quickly as possible but keep it regulated. Here is a way to bleed air from your cooling system to make sure that your radiator functions properly and you can know when it is time to replace the coolant in your car when it is below the amount required.
Tools and Materials Needed
Step 1 – Mix Water with Antifreeze Mixture
Make a mixture of ½ water and ½ antifreeze. Put it into the radiator making sure to fill it up to the rim. Fill the coolant or overflow reservoir with the same ½ water and ½ antifreeze mixture.
Step 2 – Turn Off Engine and Radiator Cover
Keep the radiator cover off. Turn off your engine and let it run until the radiator bleeds out air. The way a radiator bleeds air is when you observe the coolant level drop plus you see a large air bubble, and perhaps hear it, come out of the top of the rim. This is how the system bleeds out the air from the radiator.
Step 3 – Observe the Temperature
Observe the temperature gauge as this is happening. You should expect the temperature gauge go down to normal or close to normal. This process is not helping the radiator feed off the coolant making the radiator function properly. It is not air anymore circulating around your radiator but fresh coolant.
Step 4 – Refill the Radiator
Refill the radiator once again and the coolant reservoir as it will definitely be half full again since earlier it was simply air that makes it seam full. Fill until the top once again.
Step 5 – Cover the Radiator Rim
Cover the radiator rim with the cap. You have now bleeded your car of its air bubbles. Your car’s temperature gauge should be back to normal and you now know that it is coolant that fills your radiator and coolant reservoir and not air pockets.
