How to Remove a Broken Spark Plug?
1 Answers
Methods to remove a broken spark plug: 1. Welding Method: Weld a thin, long iron bolt onto the broken spark plug head, then remove the broken spark plug; 2. Reverse Thread Tool: Special reverse thread tools for removing broken spark plugs are available in many places. Use the reverse thread tool to tap threads inside the broken spark plug head, then turn the tool to extract the broken piece. After removal, use a magnetic rod to clean up any fallen metal fragments as much as possible. If a properly sized long flat-head screwdriver is wedged into the broken head and force is applied to shatter it into the cylinder, then a magnetic rod is used to extract the broken spark plug fragments, this method not only damages the threads on the cylinder but also fails to clean up all the fragments, potentially harming the engine. Therefore, this method is not recommended.
