Review on πŸ’‘ Helicoil 5521-5 5/16-18 Inch Coarse Thread Repair Kit: The Ultimate Solution for Thread Repair by Tropingzz Cece

Revainrating 5 out of 5

Great product, saves time, saves parts.

Works better than I could have imagined. Problem: broken screw in the 289 timing case cover. I drilled and tried two different "simple exits" but they didn't work. There must be corrosion or the wrong thread size/pitch. Ordered with the matching drill. Selected the correct size drill bit, used an excellent quality tap, installed the mentioned spiral coil. I like that it fits the screw better than the rest of the holes. very glad I did not ah. You must remove the timing cover to repair it, b. you need to change the timing cover. An absolute health saver.

Pros
  • Simple and easy to use
