New Tires

[Tom Warner]

Tom according to the Detroit diesel factory manual that I have there
are two different thermostats that can be used in your 8V92, a 170
degrees F or a 180 degrees F, they should keep the coolant in the
range of 170-187 or 180-197 degrees respectively. For the 170 degree
thermostat the coolant range should be 170-187 degrees and for the
180 degree thermostat it should be 180-197 degrees. The maximum
temperature of the coolant cannot exceed 210 degrees and the alarm
should go off at 215.

It appears that you are already exceeding these limits and I would
have your thermostats replaced and radiator and water pump checked.
