    Default Vectra C metal coolant pipe bleed screw

    About a month ago I find that there was a leak of cooling fluid by the bleed screw of my Z19DHT.

    Tried to buy a new bleed screw at GM/Opel, but in Portugal they only sell the complete pipe for € 265.00.

    From what I read in the forum, it's the same in the UK.

    After searching the internet, I discovered that the VW / Audi dealers sell the same bleed screw for € 5.30.

    For those who are interested the VW/Audi bleed screw part number is the following WHT-000-316.

    Hope it helps

    The best way of slackening the bleed screw is to use a 15mm bihex ring spanner as it will fit the screw perfectly. Using a slotted screwdriver inverably ends up by breaking the slot in the bleed screw.Like xpeixeiro says you can use a M10 x 1.5mm pitch set screw and some teflon plumbers tape if you haven't a spare.
