    I had the same problem on the deefer, the plastic nut had rounded and was stuck fast, H got a wide tipped flat head screw driver and heated it up till red hot then inserted it through the plastic plug, went had a coffee came back and unscrewed it, saved getting any plastic in the rad.

    That would not do the screwdriver any good hope it was a cheapie.

    You can get a flanged BSPP plug from any decent supplier of hose and hydraulic fittings. $2 or $3.

    Will see how i go when the replacement i ordered on ebay turns up, the aroldite is holding well enough for the moment.

    If i'm really lucky the bond will be strong enough to carefully get it unscrewed, or at least loosened enough to tap it round - otherwise it'll be the saw it out approach since the whole plastic top has come off so there wont be anywhere to get a hot screwdriver into.

    I can get a 1/2" BSP blanking plug in nickel plated brass with O-ring seal (yes there is a recess for it) with a 10mm Allen key socket.
    O-ring is NBR so this would have to be changed to Viton to withstand the temperature.

    Cost is about $3 each plus the cost of the viton O-ring.

    I'll check out viton O-rings and maybe finally get round to changing mine.
