Which prompted me to ask this question: What are normal operating
temps for the 8V92? My coach runs ~200-210 on the freeway, ~220-225
when climbing a long grade. I've never seen it hit the 230 mark,
though. Is this normal? And, what would you all consider to be the
emergency shutdown temperature, also known as the point at which the
driver poops himself trying to get the coach off the road and the
engine shut down as quickly as possible? Would like to know, in case I
do have a problem some day, would be nice to be able to save the
engine. :-)
