  • Coolant hose bleed screw

    Alright chaps,

    Is there a fix for my leaking coolant bleed screw, I'm reluctant to try and unscrew it incase it disintegrates completely!

    Not checked if a new hose is available, no doubt NLA!!!

    Cheers
    Gordon

    If you're stuck I think you can use a short M8 bolt with some plumbers PTFE thread tape.

    edit : I can't be certain of the thread pitch. Maybe its M6 you'd need to check.

      Smaller than M8, maybe even M5.

      Remember this is only 15PSI and you are sealing against rubber, over a tiny area, so a self tapper would likely hold fine, and in a pinch run with the expansion tank hose off.

      Hose is NLA, definitely, there are some silicone versions available if that is your thing -search ebay by the part number that is on the hose.

        I have resorted to jamming a short bolt into one of these in the past, though I honestly can't recall what size.

        1992 C4 100 2.8 Avant quattro, daily driver.
        1995 RS2, MTM K26/7, 380 BHP conversion.
        1997 C4 2.8 30V quattro, currently breaking for spares.
        1991 MK2 Golf G60. For sale.
        1990 Corrado G60. Looking sad.

          Cheers for the info guys, I wasn't sure what kind of thread was on it but if a small metric bolt/cap screw will fit then happy days, I'll find something suitable to plug it.
