Review on 🔧 GEARWRENCH 87911: 7 Pc. Metric Bolt Biter Impact Extraction Socket Set by Eric Surabhi

Lifebelt for removing rusted or stuck exhaust manifold bolts. You'll need a MAPGAS blowtorch, a PB blaster, and these extractors. The key is the first step, heat the bolt to cherry red, let it cool, spray on the PB blaster, leave for a while. Connect these puller tips to a 1/2" 24" snapper adapter "the longer the better". Depending on the amount of rust, you may need to try this technique multiple times. ****IMPORTANT**** Do not overtighten the screw! If the screw is stuck, do a 1/4 turn, then back, then forward, spray more PB blaster onto the threads. If you click on a rusty bolt, it will shear off. Remember patients are a virtue and MAPGAS is your friend.
