In checking the coolant level recently, I noticed a hole in the back of the
overflow tank.  Apparently, this was caused by heat from the engine being
transferred through the A/C compressor housing.  The compressor, while not
touching the coolant tank, is in close enough proximity to melt the plastic
of the tank.

In thinking about how to avoid a recurrence of this problem, it occurred to
me that there might be some kind of thin material with insulating and/or
heat reflective properties that I could glue onto the back of the
replacement coolant overflow tank.  Can anyone recommend such an item?
