Hi, I own a 2001 Citroen Berlingo van 1.4i petrol and am having problems finding the cylinder block drain valve. I've managed to drain and flush the radiator but have not managed to find the drain valve for the cylinder block, the Haynes manual hasn't really helped me on the case either. I'm also having trouble finding the other two bleed screws on the heater matrix and thermostat housing. If anyone has advice or could at least tell me what the drain valve looks like I'd greatly appreciate it. Thanks Ed
