My biggest concern with that is getting the hole drilled straight.
Probably would need to remove the radiator to have more room to work.

Having done all of the above, I would helicoil it.

I do not think I am going to helicoil it. I see the potential to make
it much worse. I see several folks on the forums mentioning they just
coated the threads with JB Weld and it has been fine. I also have seen
this Locktite thread repair and thought about trying it. Basically you
coat the bolt with a release agent, then mix the 2 part epoxy. Coat the
bolt with it then run the bolt in the hole for 5 minutes. After 5
minutes, remove the bolt and then let the epoxy set for 30 minutes
before then screwing the bolt in. Supposedly it it forms new threads
using the bolt as the pattern.

My next concern would be cleaning up the shavings after tapping and
installing the helicoil. I have first hand experience with this from
helicoiling a head hold down stud in a VW case once - despite out best
efforts at containing and then removing the chips, the engine seized in
about a mile or two. Tear-down revealed lots of aluminum shavings in the
crank bearings.
I read a tip on an airplane forum the other day where he
recommended filling the area with shaving cream before drilling, tapping,
and breaking off the tang of the helicoil, then vacuuming it out
afterwards. He claimed that you get all the chips out and that the
shaving
cream (soap) doesn't hurt anything. I've never tried this, YMMV.
It's a metric thread, use a pair of calipers and measure the diameter ---
If you don't have a pair of calipers, I can recommend this set (the HF
ones
died early and were not repeatable)

I like them so much that I bought two, one for each side of the hangar so
I'm running back and forth all the time looking for them.

Any idea what size helicoil it would be?

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?
