    Question Top Radiator Hose Bleed Screw

    Have once again got an issue with the bleed screw moulded nut coming loose in the top radiator hose of the 2001 TD5. I replaced this hose a couple of years ago because of the same problem. I now have a small leakage problem (with the bleed screw that is ) and will have a go at trying to glue the nut back in place. Just wondering if anyone else has done this successfully, and, if so, how?
    My intention is to clean around the rubber/nut as well as possible using contact cleaner then use some loctite super glue between the rubber/nut and finish of with a bit of JB Weld over and around the union. If anyone can suggest something better (other than another new top hose) I'm all ears.

    Had mine dislodge during a coolant changeout, ended up in the thermostat, spent hours locating it, **** idea.

    Gonna look at silicon hoses from Roose Motorsport which don't have the bleed screw in them as an alternative.

    I changed all my intercooler line hoses over to silicon a couple of years ago but did not do the coolant side because I need to use the bleed screw fitting.

    thanks sierrafery, sounds like Loctite 380 is the way to go.
    neat bleed screw replacement in your link... don't have to completely remove the screw to bleed. unfortunately, I have an 'engine saver' sensor fitted in place of the original screw so I can't use one of these or use a replacement silicon hose as suggested above.

    I don't recall where I bought the hose but I vaguely remember there being a LR sticker on it initially.... why do you ask?

    hi Dhickm, are you referring to a BMW hose or brass bleed valve screw?
    as I mentioned above, I need the bleed screw nut (moulded into the hose) to fit my 'engine saver' sensor.
