Stripped screws

[Christopher]

Hello all, I was replacing my thermostat, and whoever did the work before me used thread lock on the bolts. When I took them out the threads came with it. I tried to tap them, but the threads keep coming with it. Now I’m two bolt sizes up, and I’m at a loss. Any suggestions for how to proceed?

Stop tapping the holes.

I suggest you research Helicoil

Are they blind holes or through holes?

Also, I’m assuming that this is a case of steel bolts threading into aluminum.

Actually it is not uncommon.
I had removed a distributor hold down bolt.
Once removed, I noticed what I thought was some type of lock tite on the bolt itself.
Turned out to be the threads from the tapped blind hole of the block.
After cleaning the remains off the bolt and reinstalling it, it basically dropped in and bottomed out with absolutely no thread engagement.
Either it was originally over tightened from the factory or by some galvanic action, the blind hole threads came out with the bolt.

Found a solution. Mr. Grip, it’s these strips of metal I Insterted into the holes, that gave a gripping surface. Thanks for all the help!

That’s not a solution. Mr. Grip is meant to be used in hobbyist woodworking, not auto mechanics.

I hope it works for you, but I think you’ll be dealing with this situation again sooner rather than later.

I know, I just needed to find a solution to keep coolant In the engine long enough to get it to someone who actually knows what they’re doing without a tow truck!
