Default Crack Under Coolant temperature sensor

Hi guys,
I'm new to the forums so I hope I'm posting this In the right spot. I just got this 2000 grand am. It needed a new coolant temperature sensor so I decided to change it myself. Turns out I tightened it too tight and put a crack in the block or manifold? I put some JB weld on it but I'm not sure if it'll hold well or at all. If you were me, what would you do. Thanks!


The crack under the sensor

how in the world do you overtighten a sensor like that?

That is an area that is going to expand and contract due to the coolant/heat of the engine....no amount of JB Weld is going to seal that.....

Unfortunately, you have screwed yourself....

Tech II is right, JB weld could not maintain those temps you'll get in that area for more than 10 minutes or so.
But, you may have some luck with another product they make.

"" HighHeat is a hand mixable epoxy putty stick specifically formulated to bond and repair materials that will be exposed to high temperatures in automotive and industrial maintenance applications. It cures to a tough, hard bond with little to no shrinkage. This industrial-strength product outperforms conventional epoxy putties at high temperatures and sets in 1 hour at room temperature. After 8 hours, it can be drilled, tapped, machined, ground, filed and painted. HighHeat is rated at a tensile strength of 800 PSI and cures to a machine grey in color. It is able to withstand continuous heat exposure of 400F and intermittent heat exposure to 550F

Exhaust Manifolds
Tail Pipes
Mufflers

1/2" MATCO impact rated for 1300ftlbs to install a temp sensor. Seems legit.

Not my fingers. I lost fine dexterity a couple years ago due to a bad disc in my neck.
