Default Coolant leak from Oil Cooler

I've been loosing significant amounts of coolant over the last week (1 litre per 300 miles ish), in my 407 2.0 HDi RHR/BTED4. Mechanic found a significant amount of coolant crystals around the oil cooler, no water in oil or vice versa, but the questions are,

How often do these fail?

I assume the two pipes carry the coolant and engine oil is carried at the rear?

Should I try replacing the seals first or just go the whole hog and replace the whole thing with a new unit:

Oh and lastly, what's the recommended coolant?

??

TIA
