After 10 years of Northeast weather, my wastegate solenoid failed [broken and corroded wire]. No amount of pliers, vice grips or, 6" pipe wrench would free it. Accessibility was also an issue. This is the tooling I came up with to remove it. The collet/socket has a 1" hex on the end to turn and a standard length 1" open end box combo wrench gives you plenty of torque to loosen the solenoid. I cut my old carb fuel inlet wrench to install the new one in place.
