1. Park the vehicle on level ground and turn off the engine.
2. Allow the engine to cool down completely.
3. Open the hood and locate the coolant reservoir. It is usually a translucent plastic tank located near the front of the engine compartment.
4. Remove the cap from the coolant reservoir.
5. Start the engine and let it run for a few minutes. This will circulate the coolant and help to release any trapped air.
6. While the engine is running, squeeze the upper radiator hose several times. This will help to dislodge any air bubbles that may be trapped in the hose.
7. Continue to run the engine until the thermostat opens and the coolant begins to flow through the radiator. You can check this by feeling the upper radiator hose. It will become hot when the thermostat opens.
8. Once the thermostat has opened, turn off the engine and allow it to cool down completely.
9. Check the coolant level in the reservoir and add more coolant if necessary.
10. Replace the cap on the coolant reservoir.
Test drive the vehicle to ensure that the cooling system is working properly. If the vehicle overheats, there may still be air trapped in the system. Repeat steps 5-10 until all of the air has been removed.
