Helicoils don't stop bolts from coming back out. They are for when the threads are no longer useable and you still want to use the same bolt size as the original. They work well but the hole must be drilled out larger.
It is hard to say though without the milage and age to see if the hg may have already been done. Since a 20 plus year old car can get passed around alot over the years.
