I have just changed the coolant to my Cinq and upon bleeding the system of air , the bleed screw coming from the bulk head has snapped off. Does any one know the part number( I have looked on eper) or know where I can get another valve/ pipe ? Thanks.
What was in mine when I bought it was a small bolt and a small rubber O-ring. I have since seen the same size rubber O-ring at B&Q in a multi pack that had several different sizes in. There is a tapered recess where the bleed screw goes and this is how the O-ring is able to seal when using a small bolt.
