Update - Thermostat and radiator service, with 6,000 pound in tow.

[Curt Sprenger]

Update...The past few days I ran the bus about 400 miles, 6,000 pounds
in tow, outside temperature in the 80's. On the flat the coolant
temperature run 180-185, oil temperature 220. Climbing Whitewater Grade
out of Palm Springs, 40 mph head wind, the coolant temperature got up to
190 degrees, oil just over 230. I'd say changing the thermostats and
clean/rodding the radiator was a good thing to do.
