How Do You Remove A Stripped Head Bolt On A Car?
A stripped head bolt is difficult to remove. If the bolts on your engine head become stripped, usually due to over-torquing, you’ll need to drill them out. Drilling involves serious risks but is probably the only way to remove a head bolt once the threads have been stripped or the head has been broken off. You’ll need hardened drill bits for this job and a heavy-duty drill. Fit the drill bit to the head bolt. You want the drill bit to be just slightly smaller than the bolt. There is a danger that you will destroy the threads on the engine head by drilling out the bolt. Reduce this risk by using a drill bit that is smaller than the head bolt but large enough to destroy the bolt enough so that you can remove it. Secure the drill bit into the drill and tighten the chuck by turning it counterclockwise. Center the drill bit on the head bolt and start drilling slowly. You want to create a starter groove so that at higher speeds, the drill bit does not wander and damage the engine head. Incre
