I would not try to heli-coil this, not in that place. Helicoil has limits on strength of the threads. I would try to tap new threads in place first, even if it means going with maybe a more coarse thread pitch than you had before, i.e. same diameter bolt, but fewer threads per inch.
Problem is heli-coil is only going to be as strong as those springs, which require that you tap the hole anyway with a coarse threaded tool, that's what keeps the coil in place. If you can do that, why not just tap it for a larger bolt or better, one with a deeper and larger thread pattern?
Whatever the current threads are, go one step coarser, get a t-handle style tap, some cutting oil, try that first. Helicoil for me would be last resort.
Yes the fronts have some potential to bust loose inside, they thread into a small block of metal welded onto the inside of the radiator support.
My U13 had a sand/salt trap there and rusted through just in that area, you can see what you're threading into up front is not amazingly robust. I had to cut out the entire radiator support, removing all the spot welds, get a new one, etc.
Good idea to regularly blast this area out from underneath when you clean the car, make sure it drains even if you're not in the Rust Belt. I took very good care of this car but this one area wasn't getting clean, live and learn. Royal PITA job to replace and body shop quote was about $1800, so I tackled it myself instead.
