Mercedes SLK350
From day one my 182 has been losing coolant. Hoses and engine are covered in a yellow powdery residue. This residue is spattered everywhere and I top up the header tank weekly.
Renault have pressure tested the system without finding any leaks. So they have handed the car back to me, if they cant find the problem they cant fix it. Probably because its not right under their noses. But I still lose coolant.
Does anyone have any ideas where it could be coming from?
Many thanks in advance, Lee.
