I have tried to change de coolant opening the drain plug in my CRD 2.0 4x4 and I couldn't. There is no space to do it, even getting out the fascia. Soon I'll try to do it with a manual pump and getting out the lower hose. I'll tell you how it goes. Regards.Not a long time ago I could read in other forum that the drain plug can be accesed removing the passenger wheelhouse splash shield. In three or four month I'll try it and I'll tell you if I got it.
Have anybody tried in this way?
