Time for a Helicoil thread repair kit.
That mounting is a high stress area, with a repeated high failure rate.. It
needs full thread contact and regular inspection of the bolt for working
loose.
Spend the money and time to repair the thread, It should last for a good
while... Don't repair it, just kluge it with JB or something, and when it
lets go and the pulley/ belt/ fan eats whatever is handy at highway
speed... you get to buy lots of new parts and labor...
Your call... Helicoil repair kit would be mine..

Working on my fathers 98 e300 doing routine maintenance. Noticed the belt
tensioner was cockeyed. Typical. On this car the tensioner was loose with
the PO and he I believe used some lock tight and tightened it back down.
The threads were somewhat stripped out. I was aware at some point it could
become an issue. When I removed the bolt it was tight, not loose so I’m
sure the tensioner is just worn out. When I go to replace it I don’t think
I’m going to be able to crank down on it like normal. It appears the first
half of the threads are stripped so it’s just grabbing with the back half.
Think I should clean it up real good and used either red or blue locktite?
What about JB welding it? What about running a tap down the hole to clean
it up? Anybody know what size it would be or if that would even work? See
photos and video below.
