I agree with Richard C.  If you have the standard 7 psi radiator cap
(and it is working) the coolant won't boil at 212F (exact boiling temp
depends also on how much antifreeze).  In my opinion 190F is nothing
to worry about unless you stop and the fuel in the float chambers
starts to boil.  We drove our BJ7 up over Cahuenga Pass into the LA
basin with air temps above 100F.  That's stop and go traffic.  I
watched the temp needle start to work its way out of the temp gauge
part of the dial and approach the oil pressure part but the car kept
on running and there was no place to pull out of traffic anyhow.  No
sign of boil over.  No fun for the driver, though.
