Want to change coolant on 2006 Aveo

[Zomok]

How would I change the engine coolant? I didn't see a drain plug on the radiator or even a radiator cap.
I couldn't find any service manuals locally or any info online. Any help would be greatly appreciated.

Thanks

Remove the bottom hose from the rad!

There's a drain on the radiator. lower passenger side. Facing the side of the car. You'll need a 10mm socket I think to remove it.
It's plastic.
