FYI, All this talk of theromstat temps is funny, if you fit a 190 (88C) Stat that is the opening temp, the enginner I talked to at Stant says the fully open temp is 20 deg F higher. So at the fully open temp is when the by-pass is covered (closed) allowing full flow to the rad. Which is in the realm of the most efficient temps for a diesel. What UD said earlier.
WHEN DOES A THERMOSTAT START TO OPEN?
The thermostat starts to open at the rated temperature, plus or minus 2 degrees (F).
WHEN IS A THERMOSTAT FULLY OPEN?
The thermostat is usually fully opened at 15 - 20 degrees (F) above the opening temperature.
