    Hi all,

    Last year I tried to change my inverter coolant but the drain plug had been over torqued so it was a struggle. I stopped as soon as it started to strip the hex with the intention of coming back to it at a later date, armed with a longer bar (which I now have) and some liquid wrench (which I now also have).

    I would like a new plug ready to go if I do manage this time to remove it. I normally use megazip to id part numbers and buy parts but I am really struggling to find it. Does anyone by any chance know the part no?

    Thanks
