      Dieselsite 203* Thermostat for 1996-2003 Ford 7.3L Powerstroke

       

      THIS THERMOSTAT WILL FIT 1996-2003 Ford 7.3L trucks starting with Engine Serial #201681. Not for use with 1994-1995 trucks unless you have installed a 1996-2003 water pump. 

       

      203° IS THE TEMPERATURE THAT NAVISTAR-INTERNATIONAL DESIGNED THE 7.3L POWERSTROKE TO RUN AT. THIS IS THE THERMOSTAT THAT SHOULD BE IN EVERY POWERSTROKE 7.3L.

       

      Until 1996, all 7.3L Powerstrokes that were manufactured used an International water pump and an International short stem 203° thermostat.  In 1996, Ford changed the water pump design in turn changing the thermostat to a lower degree 195°.  All 1996-2003 Ford Powerstrokes now come equipped with a long stem 195° thermostat. The factory replacement thermostat available at the parts counter changed to 192° recently. Dieselsites 203° uses the correctly sized t-stat with the correct temperature spring so that we no longer have to give up the benefits of running our vehicles where they were meant to run.
