I finally decided to purchase and install the HD oil cooler today after oil temps hit about 270. Everything was going great until I put the torque wrench on the mounting nut. After a few turns, and before the torque wrench clicked, I snapped the stud bolt. I figured I would just replace the stud bolt and pulled everything back off. Unfortunately, the stud didn't come out after I tapped it with a hammer a few times. Is it actually welded in place or do I just need to keep tapping?
