How to drain the coolant from a Chevrolet Sonic 2012-2020

In this video, I show you only the exact location of the coolant drain plug (petcock) and the drainage points on a 2012-2020 Chevrolet Sonic.

Finding the precise spot where the drain is located will save you time and prevent a major mess if you are planning a DIY coolant flush or cooling system repair.

Common Symptoms and Reasons for Draining the Coolant:

• The coolant is old, discolored, or contaminated and needs a routine fluid flush
• The engine is overheating due to a clogged or failing radiator
• You need to drain the system to replace a leaking water pump, thermostat housing, or coolant hose
• Debris, rust, or scale buildup inside the cooling system is restricting proper flow
• A drop in cabin heating efficiency caused by a clogged heater core that needs service

Safety First

Always put your safety first when working with automotive fluids. You must ensure the engine is completely turned off and cool to the touch before opening the drain plug; hot coolant is under high pressure and can cause severe burns. Protect yourself by wearing safety glasses and fluid-resistant work gloves, make sure you use an appropriate drain pan to catch the fluid, and stay fully focused throughout the process.
