CHT terminal comes loss every 2 year

[Indianarob]

I have a 20-1 with IO-360 installed and about every 2 years the terminal on the CHT probe losses contact due to hight heat around the exhaust stacks.  I have been cutting it off and recripping a new terminal on it.

But I was wondering if anyone else had a better recommendation.  I was going to try soldering it this time.

Any inputs would be greatly appreciated.
