Where is the radiator drain plug on a 2006 Chevy Trailblazer?

The radiator drain plug on a 2006 Chevy Trailblazer is located at the bottom of the radiator, on the driver's side. It's usually a small bolt or plug. You'll likely need a wrench, possibly a small basin or container to catch the coolant.

Important Note: Because the location can vary slightly depending on the specific engine and radiator configuration, it's best to consult your owner's manual for the precise location and instructions. A picture in the manual would be incredibly helpful. Improper draining can cause damage, so accuracy is key.
