what about presently using 92-98 deg C thermostate

The C-15 & C-18 engines come from the factory with 195 degree farenheit thermostats, which is equal to 90.56 degrees celsius. Cat doesn't sell a lower temperature thermostat here in the U.S. We have used 180 degree thermostats from Cummins engines in the C-15, but you have to use the rubber Cat seals inside the thermostat housing with the Cummins thermostat.
