Engine bolts experience extreme stress during normal operation. This, as well as over-tightening, can sometimes lead to stripped bolts. This is potentially detrimental to your engine, and the overall safety of your vehicle. Fixing a stripped bolt is a two-part process as the bolt hole should also be repaired. Both procedures are very easy to accomplish with minimum skill and tools.
Remove stripped bolt.
Tap the hole with a tap bit slightly larger than the original threads.
Install a new bolt sized according to the tap bit you used on the hole.
