"Well...160F would be 71C -- awfully cold."

Thanks for the translation.  I switched to the 87 degree at Mark
Drillock's suggestion.  The goal is, I believe to get the engine coolant
hotter before so that what is circulating in the heating system is also
naturally hotter.  It worked for me.

Thanks,
Mike Pidcoe
