Stuck plug removal 101

I ended up stripping out the head on my stock plug, so in desperation and madness I attempted to drill it out. That didnt work but it did lead to the discovery of a trick way to remove a stuck coolant crossover plug. I used a 1/2" drill bit to drill into the plug approx. 1/4" I then took an Allen wrench that was slightly larger than 1/2" and with a small hammer drove the short end down into the plug. The 5" length of the Allen wrench gave me enough leverage to turn the plug right out.

The 1/2 drill bit above worked but use whatever size bit that you have an slightly larger allen wrench to drive into the plug. Remember when hitting the allen wrench with the hammer to drive it down into the plug that this is a case of just enough force, not as much as you can muster. Hope this helps!
