Review on 🔧 Biltek 131pc Thread Repair Kit: Professional Re-Thread Set for M5-M12 Damaged Threads, Black (NPTC-TRS131-1U) by Tyrone Narvaez

The previous owner of my 91 f150 5.8L truck chose to weld the stripped water pump studs to the block. I tried replacing the bolt with a bolt puller and broke the bolt in the head. I then bought this kit to re-cut the hole and replace the threads. Appears to be as strong as a heli coil and maybe a step below the timeline (but the corresponding timeline was too small). Bought the 131 piece kit for a little more than the m10x1.5 helix coil kit and $30 less than the m10x1.50 timing kit. Bolted the truck up and found that the PO had messed up the thermostat water neck as well (but due to my thread repair there was no leak). I would buy it again in the future but this kit means the future is a long way off. The only problem I had with the set was that the M10 tap was too big for the body and ruined the bit holder. I'm a strict reviewer so this kit only gets 4 stars (but probably worth 5). Time will tell if this kit is reliable enough for use, but so far I'm very satisfied.
