However, getting all the air out can sometimes be tricky. To help the process:
* Run the engine: Let the engine run with the heater on full blast. This helps circulate coolant throughout the system, including the heater core, which is a common air trap location.
* Check the coolant level: Monitor the coolant level in the overflow reservoir and add more as needed. Keep the radiator cap off while doing this to allow air to escape.
* Squeeze the upper radiator hose: Gently squeeze the upper radiator hose while the engine is running (but be careful, it'll be hot!). This can help dislodge air bubbles.
* Rev the engine slightly (carefully): Briefly increasing engine speed can help improve coolant circulation.
If you still have overheating issues *after* trying these steps, there might be a more serious problem such as a blockage in the cooling system, a faulty water pump, or a head gasket leak. You should take it to a mechanic for diagnosis and repair.
