This tool worked really well. I broke the heads off the bolts in my thermostat housing on my pickup truck. I have never changed it and I don't think it was changed recently by any previous owners. Because these bolts endure heat cycles and are just steel bolts, their heads twisted right off when I hit them with my ratchet and socket. What I did prior to using this tool was heat the bolts with a propane torch (MAP gas) and while it was hot, spray with PB Blaster. I did 4 or 5 rounds of this and tapped the ends of the bolts with a ball peen hammer like you would a nail. After several rounds of that and a ball of flame (PB Blaster is flammable, so keep your kids back), I attached the tool to the bolt. It is reverse threaded, so as you use your ratchet to "loosen", it is really tightening the tool around the bolt. I extracted the first easily. You hold the large chrome her nut with a BIG Crescent wrench and reverse the bolt out. Then came the second. It worked just as well on the second bolt, and I was VERY relieved as I didn't want to have to drill out the bolts. You can see in the pics of the bolts that the tool bites and holds on exposed threads well. It crushed them as you can see from the shiny threads where it bit in. Overall, I give it a 5 🌟 review. These bolts were fused to the surface of the block due to years of corrosion and nasty old thermostat gasket. I'm very happy I bought and tried this one.

The best 17 dollars I’ve ever spend literally got it in the mail had two exhaust manifold bolts broken I tried everything decided to buy this and man it broke the bolt loose so easy I would have to say it works very well

This item is very big in size. It can not fit in any tight spots to retract the bolt.
