## Questions & Answers

**Q: Will this fixed a stripped oil pan drain plug in a aluminum oil pan?**
A: Yes if your Oil Pan Drain Plug is one of the sizes in this kit.
- M5 x 0.8 x 6.7 mm
- M6 x 1.0 x 8.0 mm
- M8 x 1.25 x 10.8 mm
- M10 x 1.5 x 13.5 mm
- M12 x 1.75 x 16.3 mm

**Q: I fix my own car, but never repaired threads before. Is it hard and is this a good kit?**
A: I used this kit to repair a piece of restaurant equipment...and it worked great!  Make sure that you drill carefully and slowly, and pull out the drill regularly to shake off the drilled metal.  When "re-tapping" the newly-drilled hole, be sure that you're level to the material so that you don't tap on an angle.  Work slowly!  Tap a short distance and then back out the tapping tool and remove the metal and then continue tapping.  If I recall, I watched a few YouTube videos before doing the job.  Also, if I recall, I used some cutting oil to make the process go smoother.  Be sure to use the right size bits, coils, etc. for your application.  I had a little trouble breaking off the tab at the bottom of the coil on my first try...so I "unscrewed" the coil that I mucked up and installed a new one.  The repair has held up for more than a year, and the repair saved me over $1000 by not having to replace a part on that piece of restaurant equipment.  I have to admit, however, that I was really scared never having done this before.  Here is the cutting oil that I bought on Amazon: Forney 20857 Tap Magic Industrial Pro Cutting Fluid, 4 oz

**Q: Will it work on spark plug holes on ford aluminum heads that are off the engine**
A: Spark plugs holes are much bigger. Look for that specific tool.

**Q: Will this work for an 18mm bolt hole that needs to be rethreaded?**
A: The description clear states can go up to a M12x1.75 bolt/thread size.
You will have to determine the actual bolt/thread size being used. 18mm is the bolt head size not bolt/thread size.
Go to any hardware store and they can tell you the actual bolt/thread size.
