Locating Radiator Drain plug on e 320 cdi to drain the coolant
I am looking for the radiator drain plug and DIY for changing the coolant on e320 cdi 2005. Also I am thinking of installing the circulating heater in place of the plug for heating the coolant for canadian winter (any thoughts on this)
On the W210 it is on the lower left corner. The petcock (blue or red) is recessed into the lower radiator cross member and the front anti=noise panel needs to be removed. The nozzle faces (forward?) and you can attach a 14mm ID tygon tube to drain into a container.
