203° is the temperature that Navistar designed your truck to run at. This is the thermostat that was and still should be in every 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 to a lower degree 195° thermostat. They changed water pump designs at this time as well. The new pumps required the new long stem 195° thermostat in place of the short stem to properly seat the bypass disk. All 1996-2003 Ford PSD's now come equipped with a long stem 195° thermostat. Recently the factory replacement thermostat available at the parts counter changed to 192°. This Dieselsite 203° uses the correctly sized t-stat with the correct temperature spring so that you no longer have to give up the benefits of running your vehicle where it was meant to run.
