Drain plug on the E 320 cdi radiator

Hi,
I am looking for the drain plug or DIY procedure for flushing the coolant on e 320 cdi 2005. Also, I am thinking of installing the coolant circulating heater in the drain plug.
Thanks

Have you reached 250 000 km already? At least it should not be 15 years old yet.

Anyway, it should have a drain plug at the bottom of the radiator, you should find it after you remove the underside shields.
