This 180 Degree Cummins 3802968 Thermostat is an OEM replacement Thermostat for Cummins B3.9L/B5.9L Diesel engines. This thermostat is the stock replacement part needed for a leak-proof change for the correct engine operating temperatures.

This OEM Cummins 180 Degree Replacement Thermostat Kit contains the following required Original Equipment Manufacturer parts:

  • 3972071 Thermostat

This Cummins 3802968 Replacement Thermostat applications:

  • Cummins 4B 3.9L Diesel Engines

  • Cummins 6B B5.9L Diesel Engines
  • Cummins 6BT 5.9L Diesel Engines

Note: If your B3.9L/B5.9L engine is experiencing coolant temperature gauge cycling, replace your existing thermostat with this Cummins 3802968 180 degree thermostat. The new Cummins 3802968 thermostat provides a slower coolant response rate to reduce dramatic engine temperature cycling. This slower engine response rate does not affect the engine performance.

The Cummins 3802968 Thermostat on your B3.9L/B5.9L Cummins engine allows low-temperature coolant from the radiator into the engine to keep the operating temperature within a predetermined range. Operating a Cummins engine with a bad thermostat will cause the thermostat to get stuck in the open or closed position. A defective thermostat will cause the engine to operate either below the correct operating temperature or above it leading to an overheat condition. If you are currently experiencing any of these systems we recommend the purchase of this new and improved replacement thermostat kit to optimze engine performance. 

This 3802968 Replacement Cummins OEM  Thermostat is for the B3.9L/B5.9L Cummins engines that are MADE IN THE USA!

  • Cummins 3972071 thermostat
  • Cummins 3287754 thermostat 
  • Cummins 3917324 thermostat 
  • Cummins 3283589 thermostat 

The new and improved thermostat kit contains a 2-jiggle-pin design for
venting the coolant system compared to the previous 3-jiggle-pin design. This change was made to standardize thermostat parts across engine platforms.
