t  Only remove the new cylinder head gasket from its packing immediately before installing.
t  Handle the new gasket with extreme care. Damaging will lead to leaks.
–  Place a clean cloth in cylinders so that no dirt or emery cloth particles can get in between cylinder wall and piston.
–  Also prevent dirt and emery cloth particles from getting into the coolant.
–  Carefully clean cylinder head and cylinder block sealing surfaces. Thereby ensuring that no scoring or scratches are formed (when using abrasive paper the grade must not be less than 100).
