The heli coil is the best solution.

T-stat housing would have to be modified too. Helicoil is cheap enough, don't cobjob it.

Heli coil will bring the threads back to the original size...

Listen to the masses. Get a Helicoil kit.

Also with the Heli-coil use a dab of RTV to seal the bolt

No Sir !! You will regret doing that !! Heli Coil is hands down your best option ! Helicoil you will be able to use your factory bolt !!

Using the helicoil you only have to drill out the manifold, tap it and insert the helicoil in the manifold. Original thermostat bolt can now be reused. Housing does not get drilled. It seems you want to take the easy way out and drill out the manifold and put next size up bolt. The guys here give their opinion on how the best way to correct the problem. You now have choices so do what you want.

With 2 helicoil installs you could change course threads to fine threads. Less likely to strip out again.

The helicoil kit comes with the correct tap to install the helicoil! You will take that tap and tap out the hole! Then insert the helicoil .. Now your hole will be back to original size ! Quick easy and safe !!
