Rad drain procedure

[Brit01]

I have a 2012 aveo G3 1.6 LS (not sonic).

Need to drain and refill rad coolant.

I see there is a small plastic drain plug at the bottom of the rad on passenger side.

Any issues removing this? I'm a little afraid that plastics become brittle with heat and seals age.
Is there a risk this could break or not seal properly after removing?

Thanks

Make sure the temp is not too hot, twist the small plastic drain plug open and keep the top off of the coolant reservoir. It will drain slowly.

You can get it done faster by loosening the lower rad hose clamp and draining from there.
