What Tap for the CrankShaft Balancer Bolt
I have extracted a broken bolt out of the crankshaft. This is the Balancer Bolt that holds the Harmonic Balancer in place. I was trying to determine the proper tap that I need to use to clean the thread out. I have figured out it is an M16 Tap but am not sure whether it is 1, 1.5, or 2. I have looked everywhere and can not find any information online about what this is. The dealership of course wont help. Im gonna try and contact 800 GM TOOLS on Monday and will post the information if they know it. Otherwise im hoping someone on here might definitively know what the correct tap to use is....
