"you can add a bolt retention device"

Do I take this to mean that the three bolts are holding the pulley to the damper, and that the damper itself is only held in place due to the close tolerance of the damper vs. the crankshatf?

Matt, I have the same hook.

It has been ten years since I tore into a stovebolt, please excuse my memory failure. I simply do not wish to remove the radiator and risk damaging if i can avoid doing so.
