Product Description
Shop with Blessed Performance for the DIESELSITE 203* THERMOSTAT for your 1996-2003 FORD 7.3L Powerstroke diesel.
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°. Our Dieselsite 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.
203° IS THE TEMPERATURE THAT NAVISTAR DESIGNED YOUR TRUCK TO RUN AT. THIS IS THE THERMOSTAT THAT WAS AND STILL SHOULD BE IN EVERY POWERSTROKE 7.3L.
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.
Torque Specs for Thermostat Housings: 100-110 in-lbs.
