How to bleed the cooling system on a Chevrolet Sonic 2012-2020

In this video, I show you only the exact location of the air bleeder valve and the key connection points needed to properly bleed the cooling system on a 2012-2020 Chevrolet Sonic.

Finding the precise spot to release trapped air will save you time and eliminate frustration if you are tackling a DIY cooling system service.

Common Symptoms of Air Trapped in the Cooling System:

• The engine is overheating or the temperature gauge spikes erratically
• The heater inside the cabin blows cold air or barely gets warm, even when the engine is hot
• A bubbling, gurgling, or rushing water sound coming from behind the dashboard
• The coolant level in the expansion tank constantly drops or fluctuates rapidly after a repair
• The radiator cooling fans run continuously at maximum speed

Safety First

Always prioritize safety when dealing with the cooling system. You must ensure the engine is completely cool and turned off before loosening any plugs or valves; opening a hot system can release pressurized boiling fluid and steam, causing severe burns. Protect your eyes and skin by wearing safety glasses and fluid-resistant work gloves, and keep your full attention focused on the job.
