hi I,m costermonger and I have owned citroens as taxis for more than 15 years m, I love em BUT I need the bleed valve that is on the front of the thermostat housing on my 08 model [ latest] cv5 16 valve hdi rhr and I cannot get one , why? because some less than bright soul who composed the parts drawing on the computer did not include it ,consequently no one has the first idea how to order it,any one know ?I am not a great fan of drawing office staff because this type of lackadaisicalness has cost me in the past, I rang citroen france after falling down rapidly at the first [ and probably last[] call to the new office in Coventry but my lack of french of speakable quality kind of put up a barrier, they were however much more helpful than coventrys girl, help please guys
