    Have above Volvo, can't seem to get the Zinc plug out of the after cooler. (square nut just shears off at corners). does anyone know if it is right or left thread for sure (neither seems to work). Have tried small amount of heat but no help, the gasket prevents solvents from entering joint. Really don't want to pull the head off. The square part of the plug sticks out about 3/8 inch and is about 17mm and still quit square in spite of wrench slipping off. Have tried 12 point, flat front, open end,and pipe wrench to point of slippage.
    Frustrated any help appreciated.
